A gate 205g of the fifth transistor T5 is coupled to the light emitting control signal line pattern EM, a source S5 of the fifth transistor T5 is coupled to the power supply signal line pattern VDD, and a drain D5 of the fifth transistor T5 is coupled to the source S3 of the third transistor T3.

A gate 206g of the sixth transistor T6 is coupled to the light emitting control signal line pattern EM, a source S6 of the sixth transistor T6 is coupled to a drain D3 of the third transistor T3, and a drain D6 of the sixth transistor T6 is coupled to an anode of the light emitting element L. In some embodiments, the light emitting control signal line pattern EM to which the gate 205g of the fifth transistor T5 is coupled and the light emitting control signal line pattern EM to which the gate 206g of the sixth transistor T6 is coupled may transmit different timing signals, without limitation herein.

A gate 207g of the seventh transistor T7 is coupled to the second reset signal line pattern RST2, a drain D7 of the seventh transistor T7 is coupled to the anode of the light emitting element L, and a source S7 of the seventh transistor T7 is coupled to the second initialization signal line pattern VINT2.

A first plate Cst1 of the first capacitor Cst is coupled to the gate 203g of the third transistor T3, and a second plate Cst2 of the first capacitor Cst is coupled to the power supply signal line pattern VDD.

A first end of the second capacitor C1 (i.e., a first plate C11) is coupled to a first end of the data write transistor (e.g., the data line pattern DA), and a second end of the second capacitor C1 (e.g., a second plate C12) is coupled to the power supply signal line pattern VDD. For example: the first plate C11 of the second capacitor C1 is coupled to a data line pattern DA and/or the data write transistor T4, and the second plate C12 of the second capacitor C1 is coupled to the power supply signal line pattern VDD.

Optionally, it may be that the second plate C12 of the second capacitor C1 is electrically connected to the power supply signal line pattern VDD, and the first plate C11 of the second capacitor C1 extends below or above the data line pattern DA such that there is an overlap between orthogonal projections of the first plate C11 and the data line pattern DA on the base substrate.

Optionally, the first end of the data write transistor T4 may also be the source (or a source region, e.g., S4 of FIG. 3), or drain (or a drain region, e.g., D4 of FIG. 3), or gate (e.g., 204g of FIG. 3) of the data write transistor T4. It is to be noted that S and D in FIG. 3 are only one reference number for the purpose of distinguishing.

Optionally, the first end of the data write transistor T4 may also be a connection between the source of the data write transistor T4 and the data line pattern DA.

As shown in FIG. 4, in some embodiments, when the pixel circuit of the above-described structure is in operation, one duty cycle includes a first reset period P1, a write compensation period P2, a second reset period P3, and a light emitting period P4.

In the first reset period P1, a first reset signal input by the first reset signal line pattern RST1 is at an active level, the second transistor T2 is turned on, and an initialization signal transmitted by the first initialization signal line pattern VINT1 is input to the gate 203g of the third transistor T3, so that the gate 203g of the third transistor T3 is reset. For example: a gate-to-source voltage Vgs held on the third transistor T3 in the previous frame is cleared.

In the write compensation period P2, the first reset signal is at an inactive level, the second transistor T2 is turned off, a gate scan signal input through the gate line pattern GA is at an active level, the first transistor T1 and the data write transistor T4 are controlled to turn on, the data line pattern DA writes a data signal, and the data signal is transmitted to the source S3 of the third transistor T3 via the data write transistor T4. At the same time, the first transistor T1 and the data write transistor T4 are turned on, such that the third transistor T3 is formed as a diode structure, thus, by cooperating the first transistor T1, the third transistor T3, and the data writing transistor T4, threshold voltage compensation of the third transistor T3 is achieved, and when the compensation time is long enough, the gate 203g potential of the third transistor T3 may be controlled to eventually reach Vdata+Vth, where Vdata represents a data signal voltage value and Vth represents a threshold voltage of the third transistor T3.

In the second reset period P3, the gate scan signal is at an inactive level, the first transistor T1 and the data write transistor T4 are both turned off, a second reset signal input by the second reset signal line RST2 is at an active level, the seventh transistor T7 is controlled to be turned on, and an initialization signal transmitted by the second initialization signal line pattern VINT2 is input to the anode of the light emitting element L, so that the light emitting element L is controlled not to emit light.

In the light emitting period P4, a light emitting control signal written by the light emitting control signal line pattern EM is at an active level, the fifth transistor T5 and the sixth transistor T6 are controlled to turn on, and a power supply signal transmitted by the power supply signal line pattern VDD is input to the source S3 of the third transistor T3. At the same time, the third transistor T3 is turned on due to the gate 203g of the third transistor T3 being held at Vdata+Vth, and a gate-to-source voltage corresponding to the third transistor T3 is Vdata+Vth−VDD, where VDD is a voltage value of the power supply signal; and a drain current generated based on the gate-to-source voltage flows to the anode of the corresponding light emitting element L to drive the corresponding light emitting element L to emit light.

It is noted that when each transistor is the P-type transistor, the active level may be a low level and the inactive level may be a high level. When each transistor is an N-type transistor, the active level may be a high level and the inactive level may be a low level. The transistors of the pixel circuit may be either P-type transistors or N-type transistors, or include both P-type transistors and N-type transistors, for example: the transistor T3 is a P-type transistor and T1 is an N-type transistor. It will be appreciated that FIG. 4 is merely an exemplary introduction to the timing of operation of the pixel circuit, and the signals RST1, RST2, Ga, EM, Da, and the like may be adapted according to the transistor type of the pixel circuit and the actual situation.

As shown in FIGS. 5A to 5I, in some embodiments, when the above-described transistor array layer ZA is fabricated, the layout of all film layers is as follows: the semiconductor layer 400, the gate insulating layer 910, the third conductive layer 300, an interlayer dielectric layer 920, the second conductive layer 200, a first interlayer insulating layer 930, the first conductive layer 100, and the second interlayer insulating layer 940 are sequentially arranged in a laminated mode in a direction away from the base substrate 1000. It will be appreciated that other metal or insulating layers may also be included between the base substrate 1000 and the semiconductor layer 400. For example, at least one buffer layer or an organic insulating layer is also included between the base substrate 1000 and the semiconductor layer 400, for example, the buffer layer may be silicon oxide or silicon nitride or the like, and the organic insulating layer may be polyimide or the like.

As shown in FIGS. 5A to 5I, 6A and 7A, the semiconductor layer 400 is used to form channel regions (e.g., 101pg-107pg), source formation regions (e.g., 101ps-107ps), drain formation regions (e.g., 101pd-107pd), connection formation regions (e.g., 101px, and 102px), etc. of the transistors in the pixel circuit. Of course, other structures may also be formed as desired, such as forming a lightly doped drain (LDD) region, the LDD region doped with low concentration impurities being formed between the drain formation region (e.g., 101pd-107pd) of the at least one transistor and the channel region (e.g., 101pg-107pg) of the transistor, and between the source formation region (e.g., 101ps-107ps) of the transistor and the channel region (e.g., 101pg-107pg) of the transistor. The semiconductor layer 400 corresponding to the source formation region and the drain formation region may have better conductive properties than the semiconductor layer 400 corresponding to the channel region due to doping. Optionally, the semiconductor layer 400 may employ amorphous silicon, poly silicon, combinations thereof, or the like. For example, the semiconductor layer 400 is Low Temperature Poly Silicon (LTPS), the semiconductor layer 400 includes an oxide semiconductor material (e.g., Indium Gallium Zinc Oxide (IGZO)), and the semiconductor layer 400 includes Low Temperature Polycrystalline Oxide (LTPO). For example, as shown in FIG. 3: the semiconductor layer 400 of T3 is LTPS and the semiconductor layer 400 of T1 includes an oxide semiconductor material LTPO.

It is noted that the source formation region, the drain formation region and the connection formation region described above may be conductive regions in which n-type impurities or p-type impurities are doped in the semiconductor layer, so that the source formation region, the drain formation region and the connection formation region may be made as a connection structure of the semiconductor layer to make electrical connection. In some embodiments, the semiconductor layer corresponding to the source formation region and the drain formation region may act directly as a source or a drain of the corresponding transistor. Alternatively, a source in contact with the source formation region may be fabricated using a conductive material (e.g., a metal material) and a drain in contact with the drain formation region may be fabricated using a conductive material (e.g., a metal material).

As shown in FIGS. 5A to 5I, 6B, and 7B, the third conductive layer 300 is used to form the gates (e.g., 201g-207g) of the transistors in the pixel circuit and at least one of the structures of the gate line pattern GA, the light emitting control signal line pattern EM, the first reset signal line pattern RST1, and the second reset signal line pattern RST2 included in the display panel. Optionally, the gate 203g of the third transistor T3 in the pixel circuit is multiplexed into the first plate Cst1 of the first capacitor Cst in that pixel circuit. Of course, the gate 203g of the third transistor T3 in the pixel circuit may also be multiplexed as the second plate Cst2 of the first capacitor Cst in that pixel circuit.

As shown in FIGS. 5A to 5I, 6C, and 7C, the second conductive layer 200 has a plurality of auxiliary conductive portions WD, a plurality of storage conductive portions WCst2 disposed spaced apart from the auxiliary conductive portions WD, and the first initialization signal line pattern VINT1 and the second initialization signal line pattern VINT2 included in the display panel. The sub-pixels include the auxiliary conductive portions. In the same sub-pixel, an orthogonal projection of a first end of the auxiliary conductive portion WD on the base substrate 1000 has an overlapping region with an orthogonal projection of the power supply signal line pattern on the base substrate 1000, and an orthogonal projection of a second end of the auxiliary conductive portion WD on the base substrate 1000 has an overlapping region with an orthogonal projection of the data line pattern on the base substrate 1000. Optionally, the auxiliary conductive portions WD at least partially overlap the power supply signal line pattern, the data line pattern, and the touch electrode.

Further, the sub-pixels include the storage conductive portions WCst2 for forming the second plate Cst2 of the first capacitor Cst, i.e., the storage conductive portions WCst2 are used as the second plate Cst2 of the first capacitor Cst. Of course, the storage conductive portions WCst2 may also act as the first plate Cst1 of the first capacitor Cst. The shape structure of the auxiliary conductive portions WD is not limited, and may be a regular rectangular shape or an irregular pattern having at least one arc-shaped side. In some embodiments, one end of each auxiliary conductive portion WD extends in a row direction F4 to the other end of the auxiliary conductive portion.

As shown in FIGS. 3, 5A to 5I, 6D and 7D, the first conductive layer 100 is used to form the sources (e.g., S1-S7) and drains (e.g., D1-D7) of the transistors in the pixel circuit, as well as the data line patterns (e.g., DA1, DA2, DA3, DA4 and DA5) and the power supply signal line patterns VDD included in the display panel. Optionally, a width of each power supply signal line pattern VDD is greater than a width of the data line patterns (e.g., DA1, DA2, DA3, DA4, and DA5). It is noted that connection lines 401, 402, 403 and 404 in FIGS. 6D and 7D may be formed by the first conductive layer, with specific layouts shown in FIGS. 5A to 5I, 6D and 7D.

Of course, in practical applications, the data line pattern DA and the power supply signal line pattern VDD may also not be disposed on the same conductive layer, for example, as shown in FIGS. 7G and 7H, the first conductive layer 100 may include a first sub-conductive layer 111 and a second sub-conductive layer 112 arranged in a laminated mode with a first sub-insulating layer (not shown) disposed between the first sub-conductive layer 111 and the second sub-conductive layer 112. In some embodiments, at least one of the connection lines 401, 402, 403 and 404 is arranged on the same layer as the data line patterns (e.g. DA1, and DA2) or the power supply signal line pattern VDD. For example, the data line patterns (e.g., DA1, and DA2), and the connection lines 401, 402, and 403 may be disposed at the first sub-conductive layer 111, and the power supply signal line pattern VDD may be disposed at the second sub-conductive layer 112. That is, the data line patterns (e.g., DA1, and DA2) and the power supply signal line pattern VDD are not disposed on the same conductive layer.

In some embodiments, the first sub-conductive layer 111 where the data line patterns (e.g., DA1, and DA2) are located is closer to the base substrate 1000 than the second sub-conductive layer where the power supply signal line pattern VDD is located.

In some embodiments, the connection line 404, as a connection structure between adjacent initialization signal line patterns, may be located within the sub-pixels or may be located in the non-display region. For example, the connection line 404 connects the first initialization signal line pattern VINT1 and the second initialization signal line pattern VINT2.

In more detail, with continued reference to FIGS. 3, and 5A to 5I to 7D, the gate 201g of the first transistor T1 overlaps a first channel region 101pg, the source S1 of the first transistor T1 is located at a first source formation region 101ps, and the drain D1 of the first transistor T1 is located at a first drain formation region 101pd.

The gate 202g of the second transistor T2 overlaps a second channel region 102pg, the source S2 of the second transistor T2 is located at a second source formation region 102ps, and the drain D2 of the second transistor T2 is located at a second drain formation region 102pd.

The gate 203g of the third transistor T3 overlaps a third channel region 103pg, the source S3 of the third transistor T3 is located at a third source formation region 103ps, and the drain D3 of the third transistor T3 is located at a third drain formation region 103pd.

The gate 207g of the seventh transistor T7 overlaps a seventh channel region 107pg, the source S7 of the seventh transistor T7 is located at a seventh source formation region 107ps, and the drain D7 of the seventh transistor T7 is located at a seventh drain formation region 107pd.

The gate 203g of the third transistor T3 is multiplexed into the first plate Cst1 of the first capacitor Cst and the second plate Cst2 of the first capacitor Cst is coupled to the power supply signal line pattern VDD.

Optionally, a capacitance-conductive portion includes an auxiliary conductive portion WD, which may include the second plate C12 of the second capacitor C1, i.e., the auxiliary conductive portion may partly or wholly act as the second plate C12 of the second capacitor C1. For example: within the same sub-pixel, the auxiliary conductive portion WD acts as the second plate C12 of the second capacitor C1, and the data line pattern DA acts as the first plate C11 of the second capacitor C1; alternatively, the data line pattern DA overlapping the second plate C12 of the second capacitor C1 is used as the first plate C11 of the second capacitor C1.

As shown in FIGS. 5A to 5I, 6E, and 7E, the first electrode layer 500 is used to form first electrodes (e.g., 510, 520, 530, and 540) of the light emitting element L. In some embodiments, the first electrodes are the anodes (e.g. 510, 520, 530, and 540) of the light emitting element L. It is noted that the pixel defining layer 950 includes a plurality of opening regions (e.g., KK1, KK2, KK3, and KK4). One first electrode corresponds to one opening region, and an orthogonal projection of the opening region on the base substrate 1000 is located within an orthogonal projection of the corresponding first electrode on the base substrate 1000. For example, an opening region KK1 corresponds to a first electrode 510, an opening region KK2 corresponds to a first electrode 520, an opening region KK3 corresponds to a first electrode 530, and an opening region KK4 corresponds to a first electrode 540. In some embodiments, the first electrodes may be directly electrically connected with the semiconductor layer; alternatively, the first electrodes may also be electrically connected with the semiconductor layer through other conductive layers, for example, the first conductive layer 100.

As shown in FIGS. 5A to 5I, 6F, and 7F, the light emitting functional layer 600 is used to form a light emitting layer of the light emitting element L. For example, a first color light emitting layer 610, a second color light emitting layer 620, a third color light emitting layer 630, and a fourth color light emitting layer 640. Further, the light emitting functional layer 600 may further include film layers such as a hole injection layer, a hole transport layer, the light emitting layer, an electron transport layer, and an electron injection layer. The boundaries of the first color light emitting layer 610, the second color light emitting layer 620, the third color light emitting layer 630, and the fourth color light emitting layer 640 may or may not overlap. For example, there is an overlapping region of at least two of the first color light emitting layer 610, the second color light emitting layer 620, the third color light emitting layer 630, and the fourth color light emitting layer 640, e.g., the boundary of the first color light emitting layer 610 extends into the second color light emitting layer 620.

As shown in FIG. 2, in some embodiments, the encapsulation layer FB may include at least one or more layers of FB1, FB2, and FB3, wherein at least one layer of FB1, FB2, and FB3 is an inorganic, organic or organic-inorganic composite material, the inorganic material may be selected as at least one of silicon nitride (SiNx), silicon oxide (SiOX), silicon oxynitride (SiON) or the like, and the organic material may be polyimide (PI) or the like. For example: the encapsulation layer FB may include a first inorganic encapsulation layer FB1, an organic encapsulation layer FB2, and a second inorganic encapsulation layer FB3 disposed on top of each other. The organic encapsulation layer FB2 is located inside the blocking dam 110 and covers the display region AA. The first inorganic encapsulation layer FB1 and the second inorganic encapsulation layer FB3 cover the display region AA, the blocking dam 110 and a peripheral region of the blocking dam 110. An orthogonal projection of the first inorganic encapsulation layer FB1 on the base substrate 1000 overlaps with an orthogonal projection of the second inorganic encapsulation layer FB3 on the base substrate 1000. By extending the first inorganic encapsulation layer FB1 and the second inorganic encapsulation layer FB3 to the peripheral region of the blocking dam 110, a better water and oxygen barrier may be provided to the organic encapsulation layer FB and the display region.

As shown in FIGS. 2, 6G, 8A, and 8B, the touch electrodes 800 may include a plurality of first touch electrodes 810 and a plurality of second touch electrodes 820 arranged in a crossing mode such that an orthogonal projection of the touch electrodes 800 on the base substrate 1000 is shaped as a grid. In some embodiments, the orthogonal projection of the touch electrodes 800 on the base substrate 1000 does not overlap the orthogonal projection of the opening regions (e.g. KK1, KK2, KK3, and KK4) on the base substrate 1000. It will be appreciated that in the display panel, the touch electrodes 800 may be at least one of the plurality of first touch electrodes 810 and the second touch electrodes 820, for example: in a local display region of the display panel. For example: the touch electrodes only include the plurality of first touch electrodes 810 or the plurality of second touch electrodes 820 in sub-pixel regions at least partially corresponding to the first color, the second color, the third color and the fourth color.

In some embodiments, the plurality of first touch electrodes 810 are disposed on the same conductive film layer and the plurality of second touch electrodes 820 are disposed on the same conductive film layer. Also, a layer where the first touch electrodes 810 are located is located on a side of the encapsulation layer FB facing away from the base substrate 1000, and a layer where the second touch electrodes 820 are located is located on a side of the layer where the first touch electrodes 810 are located facing away from the base substrate 1000. An electrode insulating layer 830 is disposed between the layer where the first touch electrodes 810 are located and the layer where the second touch electrodes 820 are located. In some embodiments, the electrode insulating layer 830 may be located at and cover the display region. Alternatively, the electrode insulating layer 830 may cover not only the display region but also the non-display region. Alternatively, an edge of the electrode insulating layer 830 is located between two blocking dams BK. Of course, in practical applications, the design may be made in accordance with the practical applications, without limitation herein.

In some embodiments, one or more insulating layers (not shown) may also be disposed between the first touch electrodes 810 and the encapsulation layer FB. At least one of the insulating layers may be inorganic, organic, or organic-inorganic composite materials, the inorganic material may be selected as at least one of silicon nitride (SiNx), silicon oxide (SiOX), silicon oxynitride (SiON), or the like, and the organic material may be polyimide (PI), or the like. For example: between the first touch electrodes 810 and the encapsulation layer FB3, there is provided at least one touch electrode substrate with a material being silicon nitride (SiNx) or silicon oxide (SiOX) or polyimide (PI).

In some embodiments, the touch electrode substrate may be located at and cover the display region. Alternatively, the electrode insulating layer 830 may cover not only the display region but also the non-display region. Alternatively, the edge of the touch electrode substrate is located between two blocking dams BK. Of course, in practical applications, the design may be made in accordance with the practical applications, without limitation herein.

In some embodiments, as shown in FIG. 8A, the shape of the orthogonal projection of the first touch electrodes 810 on the base substrate 1000 and the orthogonal projection of the second touch electrodes 820 on the base substrate 1000 may be a strip. Since the first touch electrodes 810 and the second touch electrodes 820 are arranged in the crossing mode, a grid shape may be formed by the orthogonal projection of the first touch electrodes 810 on the base substrate 1000 and the orthogonal projection of the second touch electrodes 820 on the base substrate 1000. Alternatively, as shown in FIG. 8B, the shape of the orthogonal projection of the first touch electrodes 810 on the base substrate 1000 and an orthogonal projection of part of a structure of at least one of the second touch electrodes 820 on the base substrate 1000 may also be a grid.

In some embodiments, the first touch electrodes 810 and the second touch electrodes 820 are arranged in the crossing mode, and the orthogonal projection of the first touch electrodes 810 on the base substrate 1000 and the orthogonal projection of the second touch electrodes 820 on the base substrate 1000 form a grid shape. Alternatively, at least some of the first touch electrodes 810 and the second touch electrodes 820 are disposed in an overlapping mode, and the orthogonal projection of the first touch electrodes 810 on the base substrate 1000 and the orthogonal projection of the second touch electrodes 820 on the base substrate 1000 overlap.

Of course, the present disclosure includes, but is not limited to, this. In practical applications, the design may be made according to the requirements of the practical applications, and is not limited herein. The second touch electrodes 820 shown in FIG. 8B are described below as an example.

In some embodiments, as shown in FIGS. 8C and 8D, the first touch electrodes 810 may be electrically connected through a first bridge 811. A first end of the first bridge 811 may be electrically connected to one of the first touch electrodes 810 through a through hole 831 penetrating through the electrode insulating layer 830, and a second end of the first bridge 811 may be electrically connected to the other first touch electrode 810 through a through hole 832 penetrating through the electrode insulating layer 830. Similarly, as shown in FIGS. 8C and 8D, the second touch electrodes 820 may be electrically connected through a second bridge 821. A first end of the second bridge 821 may be electrically connected to one of the second touch electrodes 820 through a through hole penetrating through the electrode insulating layer 830, and a second end of the second bridge 821 may be electrically connected to the other second touch electrode 820 through a through hole penetrating through the electrode insulating layer 830.

It is noted that the light emitting element may be set as an electroluminescent diode, for example, at least one of an Organic Light Emitting Diode (OLED) and a Quantum Dot Light Emitting Diode (QLED). The light emitting element may include a first electrode layer 500 (e.g., the anode of the light emitting element), the light emitting functional layer 600, and the second electrode 700 (e.g., a cathode of the light emitting element) arranged in a laminated mode. Of course, the present disclosure includes, but is not limited to, this. In practical applications, the design may be made according to the requirements of the practical applications, and is not limited herein.

In practical applications, materials of the third conductive layer 300, the second conductive layer 200, the first conductive layer 100, the second touch electrodes 820, and the first touch electrodes 810 may or may not be the same. At least one of the third conductive layer 300, the second conductive layer 200, the first conductive layer 100, the second touch electrodes 820, and the first touch electrodes 810 includes a metal material or an alloy material or other conductive materials, such as at least one of metallic aluminum (AL), titanium (Ti), molybdenum (Mo), molybdenum niobium alloy, aluminum neodymium alloy, graphene, and the like.

Optionally, at least one of the third conductive layer 300, the second conductive layer 200, the first conductive layer 100, the second touch electrodes 820, and the first touch electrodes 810 may form a single layer structure, or a laminated structure obtained from sub-layers formed by molybdenum/aluminum/molybdenum, and titanium/aluminum/titanium.

Optionally, at least one of the third conductive layer 300, the second conductive layer 200, the first conductive layer 100, the second touch electrodes 820, and the first touch electrodes 810 has a thickness ranging from 100 nm to 500 nm.

In some embodiments: the third conductive layer 300, the second conductive layer 200, and the first conductive layer 100 may be selected from at least one of metallic aluminum (AL), titanium (Ti), molybdenum (Mo), etc.; alternatively, at least one of the second touch electrodes 820 and the first touch electrodes 810 is a laminated junction obtained from sub-layers formed by titanium/aluminum/titanium; alternatively, the material of at least one of the second touch electrodes 820 and the first touch electrodes 810 includes graphene. Since the surface reflectivity of the conductive layers is high, for example: the surface reflectivity of a molybdenum metal material is high, and the second capacitor C1 is likely to reflect external ambient light or light emitted by the light emitting functional layer 600 into the adjacent opening regions, thereby causing light emitting crosstalk or a poor light mixing effect.

In view of this, an embodiment of the present disclosure provides some display panels including a plurality of repeating units as shown in FIGS. 5A to 5I to 7F. The repeating units may include a plurality of sub-pixels, for example, the plurality of sub-pixels may include first color sub-pixels, second color sub-pixels, and third color sub-pixels. That is, the repeating units may include the first color sub-pixels, the second color sub-pixels, and the third color sub-pixels. This may enable the display panels to mix light from the first color sub-pixels, the second color sub-pixels, and the third color sub-pixels to achieve color display. In some embodiments, first, second, and third colors may be selected from red, green, and blue. For example, the second color is red, the first color is green, and the third color is blue. Of course, the embodiment of the present disclosure includes, but is not limited to, this. The first, second, and third colors described above may also be other colors.

Optionally, the repeating units may also include fourth color sub-pixels. This may enable the display panels to mix light from the first color sub-pixels, the second color sub-pixels, the third color sub-pixels, and the fourth color sub-pixels to achieve color display. In some embodiments, the fourth color sub-pixels may be green sub-pixels, or may be white sub-pixels, or may be yellow sub-pixels, or other colors, which is not limited herein.

The following is described taking an example that the repeating units include the first color sub-pixels, the second color sub-pixels, the third color sub-pixels, and the fourth color sub-pixels, the first and fourth colors are green, the second color is red, and the third color is blue.

In some embodiments, as shown in FIGS. 5A to 5I to 7F, the first color sub-pixels have the pixel circuits of any of the above embodiments, first electrodes 510, first color light emitting layers 610, and the opening regions KK1. An orthogonal projection of the first color light emitting layers 610 on the base substrate 1000 covers an orthogonal projection of the opening regions KK1 in the first color sub-pixels on the base substrate 1000, and light emitting regions of the first color sub-pixels include the opening regions KK1. In some embodiments, the opening regions KK1 may serve as the light emitting regions of the first color sub-pixels.

The second color sub-pixels include the pixel circuits of any of the above embodiments, first electrodes 520, second color light emitting layers 620, and the opening regions KK2. An orthogonal projection of the second color light emitting layers 620 on the base substrate 1000 covers an orthogonal projection of the opening regions KK2 in the second color sub-pixels on the base substrate 1000, and light emitting regions of the second color sub-pixels include the opening regions KK2. In some embodiments, the opening regions KK2 may serve as the light emitting regions of the second color sub-pixels.

The third color sub-pixels include the pixel circuit of any of the above embodiments, first electrodes 530, third color light emitting layers 630, and the opening regions KK3. An orthogonal projection of the third color light emitting layer 630 on the base substrate 1000 covers an orthogonal projection of the opening regions KK3 in the third color sub-pixels on the base substrate 1000, and light emitting regions of the third color sub-pixels include the opening regions KK3. In some embodiments, the opening regions KK3 may serve as the light emitting regions of the third color sub-pixels.

The fourth color sub-pixels include the pixel circuit of any of the above embodiments, first electrodes 540, fourth color light emitting layers 640, and the opening regions KK4. An orthogonal projection of the fourth color light emitting layers 640 on the base substrate 1000 covers an orthogonal projection of the opening regions KK4 in the fourth color sub-pixels on the base substrate 1000, and light emitting regions of the fourth color sub-pixels include the opening regions KK4. In some embodiments, the opening regions KK4 may serve as the light emitting regions of the fourth color sub-pixels.

The area of the opening regions KK1 in the first color sub-pixels is smaller than the area of the opening regions KK3 in the third color sub-pixels. The area of the opening regions KK2 in the second color sub-pixels is smaller than the area of the opening regions KK3 in the third color sub-pixels. The area of the opening regions KK4 in the fourth color sub-pixels is smaller than the area of the opening regions KK3 in the third color sub-pixels.

In some embodiments, when the emission efficiency of green light emitting elements and red light emitting elements is higher than that of blue light emitting elements, the influence on the adjacent sub-pixels is large, and thus the area of the opening regions of the green sub-pixels may be made smaller than the area of the opening regions of the blue sub-pixels, and the area of the opening regions of the red sub-pixels may be made smaller than the area of the opening regions of the blue sub-pixels, so that emission of blue light may be increased. In addition, this also results in that the second capacitors C1 of the green sub-pixels and the red sub-pixels have a larger portion that is not shielded by the opening regions, resulting in a larger exposure of the second capacitors C1, further resulting in problems of light emitting interference and poor light mixing effect.

In some embodiments of the present disclosure, as shown in FIGS. 3 to 6G, the transistor array layer includes a plurality of capacitance-conductive portions R, and at least a portion of the sub-pixels includes the capacitance-conductive portions R. There is an overlapping region between the capacitance-conductive portions R and the power supply signal line pattern VDD and/or the data line pattern in the same sub-pixel. For example, there is an overlapping region between the capacitance-conductive portions R and the power supply signal line pattern VDD and the data line pattern in the same sub-pixel. Alternatively, there is an overlapping region between the capacitance-conductive portions R and the power supply signal line pattern VDD in the same sub-pixel. Alternatively, there is an overlapping region between the capacitance-conductive portions R and the data line pattern in the same sub-pixel. Optionally, an overlap area of the capacitance-conductive portions R with the power supply signal line pattern VDD is greater than an overlap area of the capacitance-conductive portions R with the data line pattern DA.

An orthogonal projection of the capacitance-conductive portions R in the second color sub-pixels on the base substrate 1000 has a second auxiliary overlap area S2 with the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000. An orthogonal projection of the capacitance-conductive portions R in the third color sub-pixels on the base substrate 1000 has a third auxiliary overlap area S3 with the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000. An orthogonal projection of the capacitance-conductive portions R in the fourth color sub-pixels on the base substrate 1000 has a fourth auxiliary overlap area S4 with the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000. At least one of the first auxiliary overlap area S1, the second auxiliary overlap area S2 and the fourth auxiliary overlap area S4 is larger than the third auxiliary overlap area S3. For example: the first auxiliary overlap area S1 is larger than the second auxiliary overlap area S2, and the second auxiliary overlap area S2 is larger than the third auxiliary overlap area S3; or the first auxiliary overlap area S1 is larger than the second auxiliary overlap area S2 and the second auxiliary overlap area S2 is equal to the third auxiliary overlap area S3; or the first auxiliary overlap area S1 is substantially equal to the second auxiliary overlap area S2, and the second auxiliary overlap area S2 is larger than the third auxiliary overlap area S3. In this way, the second capacitors C1 may be shielded by the touch electrodes 800, which may relieve the problems of light emitting interference and poor light mixing effect caused by the second capacitors C1.

In some embodiments, as shown in FIGS. 3 to 6G, the transistor array layer ZA includes a plurality of data line patterns (e.g., DA1, and DA2) and a plurality of power supply signal line patterns (e.g., VDD). The transistor array layer ZA includes a plurality of capacitance-conductive portions R, the sub-pixels include the capacitance-conductive portions R, and the capacitance-conductive portions R have overlapping regions with the power supply signal line patterns VDD and/or the data line patterns DA. For example, the plurality of capacitance-conductive portions R are formed in the second conductive layer 200. Of course, they may also be formed in other conductive layers, such as the first conductive layer.

Optionally, at least a part of the capacitance-conductive portions R forms a capacitor with the power supply signal line patterns VDD or the data line patterns DA, i.e., there is at least one insulating layer between the capacitance-conductive portions R and the power supply signal line patterns VDD or the data line patterns DA. For example: the capacitance-conductive portions R form one capacitive plate of the second capacitor C1. Optionally, part or all of the capacitance-conductive portions form the first plate C11 or the second plate C12 of the second capacitor.

For example: the first ends of the auxiliary conductive portions WD are connected to the power supply signal line patterns VDD by a through hole of the first interlayer insulating layer 930. A second end of each auxiliary conductive portion WD extends below the data line patterns, and the auxiliary conductive portions WD have overlapping regions with the power supply signal line patterns and/or the data line patterns, that is, at the moment, the second plate C12 of the second capacitor C1 is formed on the auxiliary conductive portions WD and the first plate of the second capacitor C1 is formed on the corresponding sub-pixel data line patterns DA (e.g., DA1, and DA2); or the first plate of the second capacitor C1 is formed on the corresponding sub-pixel data line patterns DA (e.g., DA1, and DA2) having overlapping regions with the auxiliary conductive portions WD.

Optionally, the capacitance-conductive portions R may further include second auxiliary conductive portions WN2 (not shown), the second auxiliary conductive portions WN2 are formed in the second conductive layer 200, the second auxiliary conductive portions WN2 are located below the data line patterns (e.g., DA1, and DA2) of the corresponding sub-pixels, and first ends of the second auxiliary conductive portions WN2 are connected to the data line pattern (e.g., the data line pattern DA1) corresponding to each sub-pixel. For example: the first ends of the second auxiliary conductive portions WN2 are connected to the data line pattern (e.g., the data line pattern DA1) corresponding to each sub-pixel by a through hole of the first interlayer insulating layer 930. Second ends of the second auxiliary conductive portions WN2 extend below the power supply signal line patterns, and the second auxiliary conductive portions WN2 have overlapping regions with the power supply signal line patterns and/or the data line patterns, that is, at the moment, the first plate of the second capacitor C1 is formed on the second auxiliary conductive portions WN2 and the second plate of the second capacitor C1 is the power supply signal line pattern VDD; or the second plate of the second capacitor C1 is formed on corresponding sub-pixel power supply signal line patterns VDD having overlapping regions with the second auxiliary conductive portions WN2.

For ease of understanding, at least some of the embodiments described below are exemplified by taking the capacitance-conductive portions R as the auxiliary conductive portions WD. In some embodiments, since the area of the opening regions KK1 in the first color sub-pixels is smaller than the area of the opening regions KK3 in the third color sub-pixels, fewer parts of the capacitance-conductive portions R in the first color sub-pixels are shielded by the opening regions and more parts of the capacitance-conductive portions R in the third color sub-pixels are shielded by the opening regions, resulting in a stronger effect of light emitting of the capacitance-conductive portions R in the first color sub-pixels. The embodiments of the present disclosure can make more parts of the capacitance-conductive portions R in the first color sub-pixels shielded by the touch electrodes 800 by making the first auxiliary overlap area S1 larger than the third auxiliary overlap area S3, thereby reducing the problems of light emitting interference and poor light mixing effect caused by the capacitance-conductive portions R in the first color sub-pixels.

In some embodiments, since the area of the opening regions KK2 in the second color sub-pixels is smaller than the area of the opening regions KK3 in the third color sub-pixels, fewer parts of the capacitance-conductive portions R in the second color sub-pixels are shielded by the opening regions, and more parts of the capacitance-conductive portions R in the third color sub-pixels are shielded by the opening regions, resulting in a stronger effect of light emitting of the capacitance-conductive portions R in the second color sub-pixels. The embodiments of the present disclosure can make more parts of the capacitance-conductive portions R in the second color sub-pixels shielded by the touch electrodes 800 by making the second auxiliary overlap area S2 larger than the third auxiliary overlap area S3, thereby reducing the problems of light emitting interference and poor light mixing effect caused by the capacitance-conductive portions R in the second color sub-pixels.

In some embodiments, since the area of the opening regions KK4 in the fourth color sub-pixels is smaller than the area of the opening regions KK3 in the third color sub-pixels, fewer parts of the capacitance-conductive portions R in the fourth color sub-pixels are shielded by the opening regions, and more parts of the capacitance-conductive portions R in the third color sub-pixels are shielded by the opening regions, resulting in a stronger effect of light emitting of the capacitance-conductive portions R in the fourth color sub-pixels. The embodiments of the present disclosure can make more parts of the capacitance-conductive portions R in the fourth color sub-pixels shielded by the touch electrodes 800 by making the fourth auxiliary overlap area S4 larger than the third auxiliary overlap area S3, thereby reducing the problems of light emitting interference and poor light mixing effect caused by the capacitance-conductive portions R in the fourth color sub-pixels.

In some embodiments of the present disclosure, as shown in FIG. 6E, the area of the opening regions KK1 in the first color sub-pixels may be made smaller than the area of the opening regions KK2 in the second color sub-pixels. For example, the area of the opening regions of the green sub-pixels may be made smaller than the area of the opening regions of the red sub-pixels. Therefore, compared with the second color sub-pixels, in the first color sub-pixels, the capacitance-conductive portions R have fewer parts that are shielded by the opening regions. In the embodiment of the present disclosure, the first auxiliary overlap area S1 is made to be substantially equal to the second auxiliary overlap area S2, or the first auxiliary overlap area S1 is larger than the second auxiliary overlap area S2, so that compared with the second color sub-pixels, in the first color sub-pixels, the capacitance-conductive portions R have more parts that are shielded by the touch electrodes 800, thereby further reducing the problems of light emitting interference and poor light mixing effect caused by the capacitance-conductive portions R in the first color sub-pixels.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6G, the auxiliary conductive portions WD in the third color sub-pixels include third auxiliary exposure portions WD3, and an orthogonal projection of the third auxiliary exposure portions WD3 on the base substrate 1000 does not overlap the orthogonal projection of the data line pattern DA1 and the power supply signal line pattern VDD, respectively, on the base substrate 1000. The third auxiliary overlap area S3 includes a third auxiliary sub-overlap area S13, and the third auxiliary sub-overlap area S13 is located between the orthogonal projection of the third auxiliary exposure portions WD3 on the base substrate 1000 and the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000.

For example, the third auxiliary sub-overlap area S13 may be 0 μm², or 0.5 μm², or 1.0 μm², or 1.2 μm² or 2.5 μm². Of course, in practical applications, design may be determined according to the requirements of the practical application environment, which is not specifically limited herein.

In some embodiments of the present disclosure, as shown in FIGS. 9B and 9C, the auxiliary conductive portions in the fourth color sub-pixels may further include fourth auxiliary shielding portions WZ4. An orthogonal projection of the fourth auxiliary shielding portions WZ4 on the base substrate 1000 overlaps the orthogonal projection of at least one of the data line patterns and the power supply signal line patterns VDD on the base substrate 1000. The fourth auxiliary shielding portion WZ4 and the fourth auxiliary exposure portion WD4 of the same auxiliary conductive portion are integrally arranged, thereby forming the auxiliary conductive portion. In some embodiments, as shown in FIG. 9B, a width of the fourth auxiliary exposure portions WD4 in the column direction F3 may be made substantially equal to a width of the fourth auxiliary shielding portions WZ4 in the column direction F3. This may reduce the difficulty of preparing the auxiliary conductive portions in the fourth color sub-pixels.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6D, the first auxiliary sub-overlap area S11 may be made larger than the second auxiliary sub-overlap area S12. Therefore, compared with the second color sub-pixels, in the first color sub-pixels, the auxiliary conductive portions in the first color sub-pixels have more parts that are shielded by the touch electrodes 800 (e.g., the second touch electrodes 820), which may reduce the problems of light emitting interference and poor light mixing effect caused by light reflecting by the first auxiliary exposure portions WD1.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6D, the first auxiliary sub-overlap area S11 may be made larger than the third auxiliary sub-overlap area S13. Therefore, compared with the third color sub-pixels, in the first color sub-pixels, the auxiliary conductive portions in the first color sub-pixels have more parts that are shielded by the touch electrodes 800 (e.g., the second touch electrodes 820), which may reduce the problems of light emitting interference and poor light mixing effect caused by light reflecting by the first auxiliary exposure portions WD1.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6D, the fourth auxiliary sub-overlap area S14 may be made larger than the second auxiliary sub-overlap area S12. Therefore, compared with the second color sub-pixels, in the fourth color sub-pixels, the auxiliary conductive portions in the fourth color sub-pixels have more parts that are shielded by the touch electrodes 800 (e.g., the second touch electrodes 820), which may reduce the problems of light emitting interference and poor light mixing effect caused by light reflecting by the fourth auxiliary exposure portions WD4.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6D, the fourth auxiliary sub-overlap area S14 may be made larger than the third auxiliary sub-overlap area S13. Therefore, compared with the third color sub-pixels, in the fourth color sub-pixels, the auxiliary conductive portions in the fourth color sub-pixels have more parts that are shielded by the touch electrodes 800 (e.g., the second touch electrodes 820), which may reduce the problems of light emitting interference and poor light mixing effect caused by light reflecting by the fourth auxiliary exposure portions WD4.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6D, the second auxiliary sub-overlap area S12 may be made larger than the third auxiliary sub-overlap area S13 such that the first auxiliary sub-overlap area S11 is larger than the second auxiliary sub-overlap area S12 which is larger than the third auxiliary sub-overlap area S13. This allows the areas of the first auxiliary exposure portions WD1, the second auxiliary exposure portions WD2 and the third auxiliary exposure portions WD3 which are shielded by the touch electrodes (e.g., the second touch electrodes 820) to increase sequentially, thereby further reducing the problems of light emitting interference and poor light mixing effect caused by light reflecting by the first auxiliary exposure portions WD1, the second auxiliary exposure portions WD2, and the third auxiliary exposure portions WD3. Of course, it is also possible that the second auxiliary sub-overlap area S12 is substantially equal to the third auxiliary sub-overlap area S13, for example: the second auxiliary sub-overlap area S12 is equal to the third auxiliary sub-overlap area S13, both equal to 0; or the fourth auxiliary sub-overlap area S14 is at least equal to one of the first auxiliary sub-overlap area S11, the second auxiliary sub-overlap area S12, and the third auxiliary sub-overlap area S13; or the fourth auxiliary sub-overlap area S14 is larger than at least one of the first auxiliary sub-overlap area S11, the second auxiliary sub-overlap area S12, and the third auxiliary sub-overlap area S13.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 6D, the fourth auxiliary sub-overlap area S14 may be made larger than the first auxiliary sub-overlap area S11. This may make the fourth auxiliary exposure portions WD4 shielded by the touch electrodes (e.g., the second touch electrodes 820) larger than the first auxiliary exposure portions WD1 shielded by the touch electrodes, which may further reduce the problems of light emitting interference and poor light mixing effect caused by light reflecting by the fourth auxiliary exposure portions WD4. Of course, it is also possible that the fourth auxiliary sub-overlap area S14 is substantially equal to the first auxiliary sub-overlap area S11.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 7F, 10A, and 10B, the orthogonal projection of the first capacitors in the first color sub-pixels (e.g., taking the second plates Cst2 of the first capacitors as an example) on the base substrate 1000 has a first storage overlap area SC1 with the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000. In some embodiments, the first storage overlap area SC1 includes an overlap area between an orthogonal projection of the storage conductive portions Cst2 in the first color sub-pixels and the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000.

In some embodiments, as shown in FIGS. 5A to 5I to 7F, 10A, and 10B, the grid structure formed by the touch electrodes in at least one sub-pixel includes at least 5 internal angles, of which there are at least 2 obtuse angles and 2 acute angles. For example: 5 to 10 internal angles, of which there are at least 2 obtuse angles and 2 acute angles.

Optionally, the grid structure formed by the touch electrodes in at least one sub-pixel has at least 4 internal angles which are unequal. For example: in the first color sub-pixels, the second touch electrodes 820 form A1 to A5 internal angles, where A1 equals 90°, A2 and A5 are acute angles of 30° to 80°, and A3 and A4 are continuous obtuse angles of 95° to 150°.

Of course, this is not limited to the above situation. For example, optionally, A2 and A5 are equal acute angles and A3 and A4 are equal obtuse angles. Alternatively, the internal angles of the formed grid are all equal, for example: forming a regular pentagon, or a hexagon.

In some embodiments, as shown in FIGS. 5A to 5I to 7F, 10A, and 10B, the grid structure formed by the touch electrodes in at least one sub-pixel includes at least 5 sides, of which at least 2 sides are not equal in length. For example: in the first color sub-pixels, the second touch electrodes 820 form 5 sides with A1 to A5 internal angles. For example: a1 to a5 are unequal in length.

In some embodiments, as shown in FIGS. 5A to 5I to 7F, 10A, and 10B, the structure formed by the touch electrodes in at least one sub-pixel includes at least 4 sides, of which at least 2 sides are not equal in width. Optionally, a width of at least one of the sides of the touch electrodes in at least one corresponding sub-pixel is gradually reduced. For example: the width of the a4 side becomes smaller from the beginning of the A4 angle to the tail end of the A5 angle direction. Optionally, at least one of the sides of the touch electrodes in one corresponding sub-pixel includes three portions of unequal widths. For example: as shown in FIG. 9B, one side of the touch electrodes includes at least 3 portions of unequal widths, DC1 being greater than DC2 and DC1 being greater than DC4. DC4 is smaller in width, so that the overlap with power supply signal lines may be reduced and the effect on the touch signals may be reduced.

Of course, this is not limited to the above situation. For example, optionally, the touch electrodes may form a polygonal structure of equal side length or equal width. For example: a regular pentagon, and a regular hexagon.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 7F, 10A, and 10B, the orthogonal projection of the first capacitors in the second color sub-pixels on the base substrate 1000 has a second storage overlap area SC2 with the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000. In some embodiments, the second storage overlap area SC2 includes an overlap area between the orthogonal projection of the storage conductive portions Cst2 in the second color sub-pixels on the base substrate 1000 and the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 7F, 10A, and 10B, the orthogonal projection of the first capacitors in the third color sub-pixels on the base substrate 1000 has a third storage overlap area SC3 with the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000. In some embodiments, the third storage overlap area SC3 includes an overlap area between the orthogonal projection of the storage conductive portions Cst2 in the third color sub-pixels on the base substrate 1000 and the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) on the base substrate 1000.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 7F, 10A and 10B, at least one of the first storage overlap area SC1, the second storage overlap area SC2, and the fourth storage overlap area SC4 may be made larger than the third storage overlap area SC3. For example, the first storage overlap area SC1, the second storage overlap area SC2, and the fourth storage overlap area SC4 may each be made larger than the third storage overlap area SC3; alternatively, at least one of the first storage overlap area SC1 or the fourth storage overlap area SC4 is larger than the second storage overlap area SC2 which is equal to the third storage overlap area SC3.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 7F, 10A and 10B, the first storage overlap area SC1 may be made larger than the second storage overlap area SC2. This may allow the first capacitors in the first color sub-pixels to be shielded as much as possible by the touch electrodes (e.g., the second touch electrodes 820).

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I to 9B, the touch electrodes (e.g., the second touch electrodes 820) include first electrode portions DC1 and second electrode portions DC2. An orthogonal projection of the first electrode portions DC1 on the base substrate 1000 and the orthogonal projection of the auxiliary conductive portions on the base substrate 1000 have an overlapping region, and an orthogonal projection of the second electrode portions DC2 on the base substrate 1000 and the orthogonal projection of the auxiliary conductive portions on the base substrate 1000 do not overlap. A width of the first electrode portions DC1 may be larger than a width of the second electrode portions DC2. This may allow the touch electrodes to better shield the auxiliary conductive portions.

Optionally, as shown in FIGS. 5A to 5I to 9B, the touch electrodes (e.g., the second touch electrodes 820) include at least 3 portions having different widths, and the touch electrodes include the first electrode portions DC1, the second electrode portions DC2 and third electrode portions DC3 (not shown).

Optionally, the width of the first electrode portions DC1 is smaller than the width of the second electrode portions DC2, and the width of the second electrode portions DC2 is smaller than a width of the third electrode portions DC3.

Optionally, as shown in FIGS. 5A to 5I to 9B, the touch electrodes have bulges at least in one corresponding sub-pixel region, such as DC1. The touch electrodes have bulges in at least two corresponding sub-pixel regions, and the bulges differ in bulging direction or in width.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I, 6F and 6G, the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) located between adjacent opening regions on the base substrate 1000 overlaps an orthogonal projection of at least two different color light emitting layers on the base substrate 1000. Optionally, the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) located between the adjacent opening regions on the base substrate 1000 is covered by the orthogonal projection of the at least two different color light emitting layers on the base substrate 1000.

Optionally, the auxiliary conductive portions are further shielded by having at least part of a boundary ES2 of the second color light emitting layer 620 cover the auxiliary conductive portions.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I, 6F, 6G, and 11, the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) around the opening regions KK3 in the third color sub-pixels on the base substrate 1000 may be made to lie within an orthogonal projection of the third color light emitting layer 630 on the base substrate 1000. This may increase the area of the third color light emitting layer 630 to guarantee the light emitting effect.

Optionally, the auxiliary conductive portions are further shielded by having at least part of a boundary ES3 of the third color light emitting layer 630 cover the auxiliary conductive portions.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I, 6F, 6G, and 11, the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) around the opening regions KK4 in the fourth color sub-pixels on the base substrate 1000 may be made to lie within an orthogonal projection of the fourth color light emitting layer 640 on the base substrate 1000. This may increase the area of the fourth color light emitting layer 640 to guarantee the light emitting effect.

Optionally, the auxiliary conductive portions are further shielded by having at least part of a boundary ES4 of the fourth color light emitting layer 640 cover the auxiliary conductive portions.

It is to be understood that in a region where at least two color light emitting layers overlap, the position where the light emitting layers are laminated is not limited to the cases listed in the embodiment and may be adjusted according to actual circumstances or process conditions, for example: different color light emitting layers are fabricated in a single step or are fabricated in different steps. For example: the position where the light emitting layers are laminated is not limited to that in FIG. 5E, and the order is 610, 620, and 630 sequentially upwards from the pixel defining layer 950, but may be 630, 620, and 610 or 610, 630, and 620, or 630, 610, and 620, or the like sequentially upwards from the pixel defining layer 950.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I, 6F, 6G and 11, for the third color light emitting layer 630 and the second color light emitting layer 620 which are adjacent, the boundary ES3 of the orthogonal projection of the third color light emitting layer 630 on the base substrate 1000 has a first minimum distance W0S1 with a boundary CK3 of the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) surrounding the third color sub-pixels on the base substrate 1000, and the boundary ES2 of the orthogonal projection of the second color light emitting layer 620 on the base substrate 1000 has a second minimum distance W0S2 with a boundary CK1 of the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) surrounding the second color sub-pixels on the base substrate 1000. The first minimum distance W0S1 is greater than the second minimum distance W0S2. Therefore, on one hand, it may further increase the area of the third color light emitting layer 630 to guarantee the light emitting effect. On the other hand, the auxiliary conductive portions are further shielded by covering the auxiliary conductive portions with at least part of the boundary ES3 of the third color light emitting layer 630. Also, since the light emitting area of the second color sub-pixels is smaller, there is less influence on the light emitting effect of the second color sub-pixels when the third color light emitting layer 630 extends into the second color light emitting layer 620.

In some embodiments of the present disclosure, as shown in FIGS. 5A to 5I, 6F, 6G and 11, the area enclosed by the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) surrounding the opening regions KK1 in the first color sub-pixels on the base substrate 1000 is a first grid area WG1. The area enclosed by the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) surrounding the opening regions KK2 in the second color sub-pixels on the base substrate 1000 is a second grid area WG2. The area enclosed by the orthogonal projection of the touch electrodes (e.g., the second touch electrodes 820) surrounding the opening regions KK3 in the third color sub-pixels on the base substrate 1000 is a third grid area WG3. The third grid area WG3 is larger than the second grid area WG2 which is larger than the first grid area WG1. This may make the third grid area WG3, the second grid area WG2, and the first grid area WG1 proportional to the opening regions KK3 in the third color sub-pixels, the opening regions KK2 in the second color sub-pixels, and the opening regions KK1 in the first color sub-pixels, respectively, so that the light transmittance may be improved.

The first grid area WG1 corresponding to the first color sub-pixels may be made larger than the fourth grid area WG4 corresponding to the fourth color sub-pixels.
