In some embodiments, referring to
The display substrate 100 has a light exit surface (e.g., an upper surface of the display substrate 100 in
For example, referring to
As shown in
For example, as shown in
The sub-pixel P is a minimum light-emitting unit of the display substrate 100. For example, the plurality of sub-pixels P may include a plurality of first color sub-pixels P1, a plurality of second color sub-pixels P2 and a plurality of third color sub-pixels P3 (not shown in the figure). When the display substrate works, the first color sub-pixel P1 is used to emit light of the first color, the second color sub-pixel P2 is used to emit light of the second color, and the third color sub-pixel P3 is used to emit light of the third color.
The first color, the second color and the third color may be the three primary colors of light (green, blue and red), respectively. In this way, after the light of the first color, the light of the second color and the light of the third color are mixed, rich colors may be produced. For example, the first color may be green, the second color may be blue, and the third color may be red.
As shown in
A plurality of pixel circuits 130 of the plurality of sub-pixels P are electrically connected to the data drive circuit 120 located in the peripheral region BB by a plurality of data lines DL. For example, multiple pixel circuits 130 of each column of sub-pixels P are electrically connected to the data drive circuit 120 by a data line DL.
The plurality of pixel circuits 130 of the plurality of sub-pixels P are electrically connected to the gate drive circuits 110 by a plurality of first gate lines GL1 and a plurality of second gate lines GL2.

For example, the switching device may be a thin film transistor (TFT) or a field effect transistor (e.g., metal oxide semiconductor transistor, MOS transistor). The embodiments of the present disclosure are described by considering an example where the switching devices are TFTs. That is, the pixel circuit 130 includes a plurality of TFTs. The TFT may be a P-type transistor or an N-type transistor. The P-type transistor is turned on due to the action of a low potential and turned off due to the action of a high potential; and the N-type transistor is turned on due to the action of a high potential and turned off due to the action of a low potential.
For examples, as shown in
The display substrate 100 further includes an anode layer 21, a pixel defining layer 22, a light-emitting functional layer 23 and a cathode layer 24 that are disposed on a side of the pixel circuits 130 away from the substrate 11.

The organic material layer 26 may be used to planarize the light exit surface of the display substrate 100 and release stress of the display substrate 100.
As shown in
Referring to
In some embodiments, the touch layer 200 may further include a buffer layer and a protective layer. For example, the buffer layer is disposed between the encapsulation layer 150 and both the first metal layer 210 and the second metal layer 220, and may play a role of protecting the second inorganic material layer 27. The protective layer is disposed on a side of both the first metal layer 210 and the second metal layer 220 away from the substrate 11, and may play a role of protecting the first metal layer 210 and the second metal layer 220. For example, in a case where the first metal layer 210 is provided further away from the display substrate 100 than the second metal layer 220, the buffer layer may be disposed between the second inorganic material layer 27 and the second metal layer 220, and the protective layer may be disposed on a side of the first metal layer 210 away from the substrate 11.
One of the first metal layer 210 and the second metal layer 220 includes a plurality of first touch electrodes 31, a plurality of second touch electrodes 32 and a plurality of connection portions 33, and the other of the first metal layer 210 and the second metal layer 220 includes a plurality of bridge portions 34. The first insulating layer 230 is provided with a plurality of via holes 35 therein.
For example, referring to
Each connection portion 33 connects two adjacent first touch electrodes 31, and each bridge portion 34 connects two adjacent second touch electrodes 32 through via holes 35 (as shown in
Alternatively, each connection portion connects two adjacent second touch electrodes, and each bridge portion connects two adjacent first touch electrodes through via holes (not shown in the figure).
Referring to
At least one of the first touch electrodes 31, the second touch electrodes 32, the connection portions 33 and the bridge portions 34 includes the metal mesh structure 201. For example, the first touch electrodes 31, the second touch electrodes 32, the connection portions 33 and the bridge portions 34 all include the metal mesh structure 201.
The metal mesh structure 201 includes a plurality of metal lines 40, and the metal mesh structure 201 includes a plurality of grids 50 surrounded by the plurality of metal lines 40. In the embodiments of the present disclosure, a metal line 40 refers to the smallest continuous line segment that surrounds a grid 50 and extends in direction of a straight line. That is, the grid 50 refers to a pattern surrounded by multiple metal lines 40 connected end to end.
As shown in
A plurality of openings 411 in the plurality of first metal lines 41 divide the metal mesh structure 201 into the plurality of first touch electrodes 31 and the plurality of second touch electrodes 32 that are insulated from each other. For example, as shown in
It can be understood that the shape of the grid 50 may include at least one of a triangle, a rectangle, a pentagon, a hexagon or other irregular shapes. Of course, the shape of the grid 50 may alternatively be in another shape composed of at least one straight line and at least one curve line. The embodiments of the present disclosure do not specifically limit the shape of the grid 50. Therefore, it will be understood that the metal mesh structure 201 shown in
Similarly, the shape of the anode 211 may be a circle, an ellipse, a rectangle, a rhombus, or any other shape. The anode 211 may alternatively be in any other shape composed of at least one straight edge and at least one curved edge. There is no specific limit on this in the embodiments of the present disclosure. The anode 211 shown in
As shown in
When the display panel 1100 works, part of the light emitted by the light-emitting functional patterns 231 exits through the display panel 1100 in a direction substantially perpendicular to the substrate 11 and away from the substrate 11, and part of the light is incident on the anode 211 in a direction substantially perpendicular to the substrate 11 and towards the substrate 11, and then exits through the display panel 1100 in the direction substantially perpendicular to the substrate 11 and away from the substrate 11 after being reflected by the anode 211. Part of the exiting light is directed to metal lines 40 of the metal mesh structure 201, and cannot exit through the light exit surface of the display panel 1100 after being blocked by the metal lines 40.
In the related art, the metal line 40 can block the light exiting from the display substrate 100. However, in the grid 50 formed by the first metal lines 41, the opening 411 of the first metal line 41 cannot block the light exiting from the display substrate 100. Therefore, compared with the amount of light exiting from other positions where the metal line 40 (including the two metal sub-lines of the first metal line 41) is provided, more light exits at the opening 411. As a result, there is a difference between amounts of light exiting from different positions of the display panel 1100, resulting in poor uniformity of light exiting from the display panel 1100, thereby affecting the display effect of the display apparatus 1000.
In order to solve the above technical problem, referring to
In some embodiments, referring to
For example, in a case where the length D1 of the groove 2111 in the first direction M1 is substantially equal to the length D2 of the opening 411 in the first direction M1, two ends of the groove 2111 in the first direction M1 are respectively substantially flush with two ends of the opening 411 in the first direction M1.
For example, as shown in
In some embodiments, in a case where the length D1 of the groove 2111 in the first direction M1 is greater than the length of the opening 411 in the first direction M1, the length of the groove in the first direction M1 is D1, the length of the opening 411 provided opposite to the groove 2111 is D2, and D1 is equal to a sum of D2 and a value ranging from 0.1 μm to 1 μm, inclusive (i.e., D1=D2+ (0.1 μm to 1 μm)). That is, the length of the groove 2111 is 0.1 μm to 1 μm greater than the length of the opening 411. For example, D1 is equal to a sum of D2 and 0.1 μm (i.e., D1=D2+0.1 μm); alternatively, D1 is equal to a sum of D2 and 0.4 μm (i.e., D1=D2+0.4 μm); alternatively, D1 is equal to a sum of D2 and 0.7 μm (i.e., D1=D2+0.7 μm); alternatively, D1 is equal to a sum of D2 and 1 μm (i.e., D1=D2+1 μm). The embodiments of the present disclosure will not list this one by one.
It can be understood that if the length of the groove 2111 in the first direction M1 is too short, part of the light reflected by portions of the anode 211 located on both sides of the groove 2111 may exit from the opening 411, which is not conducive to improving the uniformity of the light exiting from the display panel 1100. Therefore, D1 is greater than or equal to the sum of D2 and 0.1 μm (i.e., D1>D2+0.1 μm). If the length of the groove 2111 in the first direction M1 is too long, the amount of the light reflected by the anode 211 may be caused to be reduced, and thus the light extraction efficiency of the display panel 1100 may be reduced. Based on this, D1 is less than or equal to the sum of D2 and 1 μm (i.e., D1≤D2+1 μm).
For example, the length D2 of the opening 411 in the first direction M1 may be in a range of 3 μm to 5 μm, inclusive. Based on this, the length D1 of the groove 2111 in the first direction M1 may be in a range of 3.1 μm to 6 μm, inclusive. For example, the length D2 of the opening 411 is 3 μm, and the length D1 of the groove 2111 may be 3.1 μm, 3.5 μm, or 4 μm; alternatively, the length D2 of the opening 411 is 3.5 μm, and the length D1 of the groove 2111 may be 3.6 μm, 3.9 μm, or 4.5 μm; alternatively, the length D2 of the opening 411 is 5 μm, and the length D1 of the groove 2111 may be 5.1 μm, 5.3 μm or 6 μm. The embodiments of the present disclosure are not listed one by one here.
In some embodiments, the groove 2111 is arranged symmetrically about a reference plane X. This is beneficial to improving the uniformity of light exiting from both sides of opening 411 in the first direction M1. The reference plane X is perpendicular to the substrate 11 and passes through a center line L4 of the opening 411 extending in the second direction M2. The second direction M2 is parallel to the substrate 11 and perpendicular to the first direction M1.
In some embodiments, in the first direction M1, a difference between the length D1 of the groove 2111 and the length D2 of the opening 411 provided opposite to the groove 2111 is D3, that is, D3 is equal to a difference between D1 and D2 (i.e., D3=D1-D2). In the second direction M2, a depth of the groove 2111 is D4. D4 is equal to a value ranging from 0.3 times D3 to 0.7 times D3 (i.e., D4=(0.3 to 0.7)×D3). That is, the depth of the groove 2111 is 0.3 to 0.7 times the difference between the length of the groove 2111 and the length of the opening 411. In this way, the groove 2111 may not only reduce the light exiting through the opening 411 after being reflected by the anode 211, but also reduce a deformation degree of the light-emitting region of the sub-pixel P caused by the groove 2111 and reduce an influence of the groove 2111 on an overall shape of the anode 211. This is beneficial to improving the light extraction efficiency of the display panel 1100. As shown in
For example, D3 may be in a range of 0.1 μm to 1 μm, inclusive. Moreover, taking into account the ability of the groove 2111 reducing the reflection of the anode 211, the depth D4 of the groove 2111 may be in a range of 0.1 μm to 0.7 μm, inclusive. For example, the depth D4 of the groove may be 0.1 μm, 0.2 μm, 0.5 μm or 0.7 μm. In different products, the depth of the groove 2111 may be specifically set according to the actual optical effect.

For example, referring to
In some embodiments, in a case where the display substrate 100 includes the first display region AA1 and the second display region AA2, and the light transmittance of the first display region AA1 is greater than the light transmittance of the second display region AA2, the plurality of anodes 211 may include both a plurality of first anodes 211A and a plurality of third anodes 211C that are located in the first display region AA1 (as shown in
The metal mesh structure 201 includes a plurality of first grids 51, and each first grid 51 includes at least two first metal lines 41, that is, the first grid 51 includes at least two openings 411. In this way, the at least two openings 411 may divide the first grid 51 into at least two portions that are insulated from each other, so that the first grid 51 is at least located in a first touch electrode 31 and a second touch electrode 32.
An orthogonal projection of the first grid 51 on the substrate 11 surrounds an orthographic projection of at least one first anode 211A on the substrate 11. An edge of each first anode 211A includes at least one groove 2111. That is, some anodes 211 located in the first display region AA1 and surrounded by the first grids 51 are the first anodes 211A, and at least one groove 2111 is provided in the first anode 211A.
An orthogonal projection of each groove 2111 of the first anode 211A on the substrate 11 is provided opposite to an opening 411 of the first grid 51 (the first metal line 41). This is beneficial to improving the display uniformity of the first display region AA1.
In some embodiments, referring to
In some other embodiments, referring to
Referring to
A line width D5 of the first metal line 41 is smaller than a line width D6 of the second metal line 42. That is, in the first display region AA1, the line width of the metal line 40 with the opening 411 is smaller than the line width of the continuous metal line 40 (the metal line 40 without the opening 411). In this way, resistance of a portion of the metal mesh structure 201 located in the first display region AA1 may be reduced through the second metal line 42, and a distance between the first metal line 41 and the anode 211 may be reduced through the first metal line 41, so that the enclosed first grid 51 may have a large space. This is beneficial to enlarging an area of the anode 211, thereby compensating for a decrease in area of the first anode 211A caused by the groove 2111, and ensuring an effective light-emitting area and a light extraction rate of the sub-pixel P where the first anode is located.
In some embodiments, referring to
In some embodiments, as shown in
It can be understood that metal lines 40 that are close to each other in two adjacent grids 50 are shared, that is, each metal line 40 located between two anodes 211 may be used to surround to form at least two grids 50.
The plurality of anodes 211 further includes a plurality of second anodes 211B. The plurality of second anodes 211B are located in the second display region AA2, and an orthogonal projection of each second grid 52 on the substrate 11 surrounds an orthographic projection of at least one second anode 211B on the substrate 11. An orthogonal projection of the opening 411 of the second grid 52 (the first metal line 41) on the substrate 11 is provided opposite to the groove 2111 of the second anode 211B.
In some embodiments, similar to the first grid 51, the orthogonal projection of the second grid 52 on the substrate 11 surrounds an orthographic projection of a single second anode 211B on the substrate 11, and two grooves 2111 are provided in edges of the second anode 211B.
In some other embodiments, similar to the first grid 51, the orthogonal projection of the second grid 52 on the substrate 11 may surround orthographic projections of multiple (e.g., two) second anodes 211B on the substrate 11, two openings 411 of the second grid 52 are respectively provided opposite to different second anodes 211B, and thus each second anode 211B may include a groove 2111.
In some embodiments, as shown in
In a case where the plurality of metal lines 40 include the plurality of third metal lines 43, the second grid 52 includes at least two first metal lines 41 and multiple third metal lines 43. For example, as shown in
The line width of the first metal line 41 is substantially equal to the line width of the third metal line 43. That is, the line widths of the second grid 52 are equal everywhere. This is beneficial to improving the uniformity of the metal lines 40 in the second display region AA, so that the metal lines 40 have substantially the same blocking effect on the light exiting from the sub-pixel P, thereby improving the display uniformity of the second display region AA2.
It can be understood that for the first anode 211A and the second anode 211B each for forming sub-pixels of the same color, the structures of the two may be the same. However, the first anode 211A is located in the first display region AA1, and the second anode 211B is located in the second display region AA2. For example, the first anode 211A for forming the first color sub-pixel P1 and located in the first display region AA1 may have the same structure as the second anode 211B for forming the first color sub-pixel P1 and located in the second display region AA2.
Referring to
The metal mesh structure 201 further includes a plurality of third grids 53 and a plurality of fourth grids 54. Orthogonal projections of the plurality of third grids 53 and the plurality of fourth grids 54 on the substrate 11 are continuous closed patterns. That is, there are no openings 411 in the third grid 53 and the fourth grid 54. Therefore, the third grid 53 and the fourth grid 54 have substantially the same blocking effect on the light exiting from the sub-pixels P.
An orthogonal projection of each third grid 53 on the substrate 11 surrounds an orthographic projection of a third anode 211C on the substrate 11. That is, the third grid 53 is located in the first display region AA1. In a case where the metal mesh structure 201 (the plurality of metal lines 40) includes a plurality of second metal lines 42 located in the first display region AA1, the third grid 53 may include multiple second metal lines 42 connected end to end.
An orthogonal projection of each fourth grid 54 on the substrate 11 surrounds an orthographic projection of a fourth anode 211D on the substrate 11. That is, the fourth grid 54 is located in the second display region AA2. In a case where the metal mesh structure 201 (the plurality of metal lines 40) includes a plurality of third metal lines 43 located in the second display region AA2, the fourth grid 54 may include multiple third metal lines 43 connected end to end.
In some embodiments, as shown in
For example, as shown in
In some embodiments, areas of the first anode 211A, the second anode 211B, the third anode 211C and the fourth anode 211D included in a plurality of first color sub-pixels P1 are substantially equal. That is, the areas of the anodes 211 of all the first color sub-pixels P1 are substantially equal. In this way, the luminous uniformity of the first color sub-pixels P1 in different regions and/or with different structures of anodes 211 may be improved. That is, each first color sub-pixel P1 has substantially the same effective display area and exits substantially the same light.
Areas of the first anode 211A, the second anode 211B, the third anode 211C and the fourth anode 211D included in a plurality of second color sub-pixels P2 are substantially equal. That is, the areas of the anodes 211 of all the second color sub-pixels P2 are substantially equal. In this way, the luminous uniformity of the second color sub-pixels P2 in different regions and/or with different structures of anodes 211 may be improved. That is, each second color sub-pixel P2 has substantially the same effective display area and exits substantially the same light.
Areas of the first anode 211A, the second anode 211B, the third anode 211C and the fourth anode 211D included in a plurality of third color sub-pixels P3 are substantially equal. That is, the areas of the anodes 211 of all the third color sub-pixels P3 are substantially equal. In this way, the luminous uniformity of the third color sub-pixels P3 in different regions and/or with different structures of anodes 211 may be improved. That is, each third color sub-pixel P3 has substantially the same effective display area and exits substantially the same light.
It can be understood that the above embodiments of the present disclosure may be flexibly combined according to actual needs. For example, only at least part of the first anodes 211A may be provided with the grooves 2111; alternatively, only edges of at least part of the second anodes 211B may be provided with the grooves 2111. The structures of the grooves 2111 in different anodes 211 may be the same or different. For example, an edge of one of the groove 2111 of the first anode 211A and the groove 2111 of the second anode 211B is in a zigzag shape, and an edge of the other is substantially in a straight shape. In the embodiments of the present disclosure, combinations of the above various embodiments are not listed one by one.
The foregoing descriptions are merely specific implementation manners of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Changes or replacements that any person skilled in the art could conceive of within the technical scope of the present disclosure shall all be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
