The first pixel circuits are electrically connected to the first light-emitting elements, the first light-emitting elements are located in the first display region, and the first pixel circuits are located in the third display region. The second pixel circuits are electrically connected to the second light-emitting elements, and the second pixel circuits and the second light-emitting elements are located in the second display region.

The present disclosure provides a display panel.
The display panel 100 includes a first display region DA1, a second display region DA2, a third display region DA3, and a fourth display region DA4. The third display region DA3 is located at least one side of the first display region DA1 along a first direction X. The second display region DA2 at least partially surrounds the first display region DA1 and the third display region DA3. The first display region DA1 is reused to be a photosensitive element integration region. The fourth display region DA4 is located between the third display region DA3 and the second display region DA2, and between the first display region DA1 and the second display region DA2 along a second direction Y which intersects with a first direction X. In some embodiments, the display panel 100 further includes a non-display region (not shown). The non-display region surrounds the first display region DA1, the second display region DA2, the third display region DA3, and the fourth display region DA4.
The display panel 100 further includes a first pixel circuit C1 and a first light-emitting element P1 that are electrically connected to each other, a second pixel circuit C2 and a second light-emitting element P2 that are electrically connected to each other, a third pixel circuit C3 and a third light-emitting element P3 that are electrically connected to each other, a fourth pixel circuit C4 and a fourth light emitting element P4 that are electrically connected to each other.
The first light-emitting element P1 is located in the first display region DA1, and the first pixel circuit C1 is located in the third display region DA3. In some embodiments, each first pixel circuit C1 is electrically connected to at least one first light-emitting element P1 through corresponding connection lines CL. The second pixel circuit C2 and the second light emitting element P2 that are electrically connected to each other are located in the second display region DA2. The third pixel circuit C3 and the third light emitting element P3 that are electrically connected to each other are located in the third display region DA3. The fourth pixel circuit C4 and the fourth light-emitting element P4 that are electrically connected to each other are located in the fourth display region DA4. In some embodiments, in addition to the first pixel circuit C1 and the third pixel circuit C3, a virtual pixel circuit CD may also be arranged in the third display region DA3. The virtual pixel circuit CD can balance density of etching patterns of different display regions, improving etching uniformity or display uniformity. In some embodiments, the virtual pixel circuit CD may not be provided in the third display region DA3. It can be understood that in order to ensure that the first display region DA1 can display an image normally, the light-emitting elements of the first display region DA1 meet a number, and the number of connecting line CL is large, and the connecting lines CL may be set densely at adjacent positions between the first display region DA1 and the third display region DA3.
The fourth pixel circuits C4 are arranged in at least one row in the fourth display region DA4. Each row of the fourth pixel circuits C4 includes at least one first arrangement unit U1 arranged along the first direction X. Each first arrangement unit U1 includes N fourth pixel circuits C4 and a first interval space K1, where N is a positive integer. The N fourth pixel circuits C4 are successively arranged adjacent to each other along the first direction X, and the first interval space K1 is located at a side of the N fourth pixel circuits C4 along the first direction X.
The display panel 100 further includes multiple first data lines 110. Each first data line 110 is electrically connected to at least one first pixel circuit C1 and at least one second pixel circuit C2. At least one first data line 110 passes through the first interval space K1, so that orthographic projections of multiple first data lines 110 on the display surface do not overlap with orthographic projections of the connecting lines CL on the display surface.
According to the display panel 100 of the embodiments of the present disclosure, the fourth pixel circuits C4 are arranged in at least one row in the fourth display region DA4, and each row of the fourth pixel circuits C4 includes first arrangement units U1. Each first arrangement unit U1 includes the first interval space K1, that is, at least one pixel circuit in the fourth display region DA4 that is not connected to the light-emitting element is removed to obtain the first interval space K1. The first interval space K1 can be used as a winding space for the first data lines 110, and at least one first data line 110 passes through the first interval space K1, thereby reducing or even preventing the first data lines 110 from passing through the first display region DA1. Therefore, overlapping between the orthographic projection of the first data line 110 on the display surface and the orthographic projection of the wire (e.g., the connection line CL) connected to the first display region on the display surface is reduced, and it is avoided that densely arranged wires that overlap with the first data lines 110 affect the loads of the first data lines 110, thereby avoiding affecting the data signals. In this case, a load difference between the part of the first data line 110 in the third display region DA3 and the part of the first data line 110 in the second display region DA2 is greatly reduced, and a load difference between the data lines in different display regions can also be reduced. The influence of the wire, such as the connection line CL, on the coupling crosstalk of the first data line 110 is reduced, so that the brightness of the first light emitting element P1 tend to be the same as that of the second light emitting element P2, thereby improving the uniformity of the display brightness of the display panel 100. In general, in order to match the brightness of light-emitting elements in different regions, the driving current corresponding to the light-emitting element with lower brightness can be increased, however, increasing the driving current can shorten the service life of the light-emitting element, which can affect the service life of the entire display panel and display effect. In this case, by changing the structural design of the display panel, the load difference between the part of the first data line 110 in the third display region DA3 and the part of the first data line 110 in the second display region DA2 can be reduced, and the brightness difference between the first light-emitting element P1 and the second light-emitting element P2 can be reduced, thereby improving the uniformity of display brightness of the display panel 100, while improving the service life of the first light-emitting element P1, and further increasing the service life of the display panel 100.
In some embodiments, the fourth pixel circuits C4 are arranged in one row in the fourth display region DA4. In other embodiments, the fourth pixel circuits C4 can be arranged in two rows, three rows, or other number of rows in the fourth display region DA4.
Each row of the fourth pixel circuits C4 includes at least one first arrangement unit U1. Each first arrangement unit U1 includes a first interval space K1. In some embodiments, the number of first arrangement units U1 in each row of the fourth pixel circuits C4 is two or more, so that there are two or more first interval spaces K1.
In some embodiments, at least one of the fourth pixel circuits C4 in each row of the fourth pixel circuits C4 can be replaced with a virtual pixel circuit that is configured to not emit light by the light-emitting element.
As shown in
In some embodiments, a length of the first interval space K1 along the first direction X is 0.5 times to 3 times a length of the fourth pixel circuit C4 along the first direction X. For example, in some embodiments, the length of the first interval space K1 along the first direction X is 0.5 times the length of a single fourth pixel circuit C4 along the first direction X. For example, in some embodiments, the length of the first interval space K1 along the first direction X is 3 times the length of the single fourth pixel circuit C4 along the first direction X. When the length of the first interval space K1 along the first direction X is excessively short, an effective wire accommodation space cannot be formed, so that the first data line 110 is difficult to pass through the first interval space K1. When the length of the first interval space K1 along the first direction X is excessively longer, the arrangement space of the fourth pixel circuits C4 will be squeezed, so that the number of the fourth pixel circuits C4 in the fourth display region DA4 is excessively small, which is not conducive to driving display panel with a high pixel density: The length of the first interval space K1 along the first direction X is set to be 0.5 times to 3 times the length of the single fourth pixel circuit C4 along the first direction X, so that it is possible to balance the winding space of the first data line 110 and the arranging space of the fourth pixel circuit C4, thereby reducing the load influence of other wirings on the first data line 110 while ensuring better driving performance.
Multiple row units RX include at least one first row unit R1 adjacent to the fourth display region DA4. Each first row unit R1 includes multiple second arrangement units U2 arranged along the first direction X. Each second arrangement unit U2 includes P first preset pixel circuits and a second interval space K2, where P is a positive integer. The first preset pixel circuit includes at least one of a first pixel circuit C1, a third pixel circuit C3, or a first virtual pixel circuit. P first preset pixel circuits are adjacent to each other along the first direction X, and the second interval space K2 is located at a side of the P first preset pixel circuits along the first direction X. For example, in some embodiments, the second arrangement units U2 each include three first preset pixel circuits, which can be the first pixel circuits C1 or the third pixel circuits C3. Since the second interval space K2 is provided in the third display region DA3, the first data line 110 can also pass through the second interval space K2, which further increases the wiring space of the first data line 110, thereby reducing the overlapping area between the orthographic projection of the first data line 110 on the display surface and the orthographic projection of the connecting line CL on the display surface. Meanwhile, the first data lines 110 passes through the second interval space K, that is, at least a part of the first data sub-lines 111 in the first data lines 110 can be arranged in the second interval space K, so that a distance between the first data line 110 and the data line electrically connected to the third pixel circuit C3 located in the third display region D3 can be increased, and coupling crosstalk between adjacent data signal lines, thereby improving the display effect of the display panel.
In some embodiments, at least one second interval space K2 communicates with the first interval space K1 along the second direction Y, so that the second interval space K2 and the first interval space K1 are connected to each other to form a strip wiring space, which is convenient for the wiring of the first data lines 110 in the second interval space K2 and the first interval space K1.
In some embodiments, the length of the second interval space K2 along the first direction X is 0.5 times to 3 times the length of the first pixel circuit C1 along the first direction X. For example, in some embodiments, the length of the second interval space K2 along the first direction X is 0.5 times the length of the single first pixel circuit C1 along the first direction X. For example, in another embodiment, the length of the second interval space K2 along the first direction X is three times the length of the single first pixel circuit C1 along the first direction X. When the length of the second interval space K2 along the first direction X is excessively short, an effective wiring accommodation space cannot be formed, so that the first data line 110 is difficult to pass through the second interval space K2. When the length of the second interval space K2 along the first direction X is excessively longer, the arrangement space of the first pixel circuit C1 and the third pixel circuit C3 will be squeezed, and the pixel densities of the first display region DA1 and the third display region DA3 will be reduced., which is not conducive to driving display panel with a high pixel density. The length of the second interval space K2 along the first direction X is set to be 0.5 times to 3 times the length of the single first pixel circuit C1 along the first direction X, so that it is possible to balance the winding space of the first data line 110 and the arranging space of the first pixel circuit C1 and the third pixel circuit C3, thereby reducing the load influence of other wirings on the first data line 110 while ensuring better driving performance. In addition, when the length of the second interval space K2 along the first direction X is equal to the length of the first interval space K1 along the first direction X, and the second interval space K2 communicates with the first interval space K1, it is convenient to form regular wiring space to accommodate more winding structures of the first data lines 110.
In each second row unit R2, multiple second preset pixel circuits are arranged adjacently in sequence along the first direction X, and include at least one of a first pixel circuit C1, a third pixel circuit C3, or a second virtual pixel circuit. For example, in some embodiments, the second preset pixel circuit in each second row unit R2 simultaneously includes a first pixel circuit C1, a third pixel circuit C3 and a second virtual pixel circuit CD2. In the above embodiments, the first row unit R1 can be obtained by selectively removing part of the pixel circuits on the original structure of the display panel, while the second row unit R2 does not need to be screened to remove the pixel circuits. When the display panel 100 still includes some second row units R2, the process of screening pixel circuits to be removed can be omitted, thereby improving the layout design efficiency.
In some embodiments, in each third display region DA3, the number of first row unit R1 is equal to the number of fourth display region DA4 adjacent to the third display region DA3, and each first row unit R1 is adjacent to a corresponding fourth display region DA4. For example, in the embodiments shown in
In some embodiments, fourth display regions DA4 are provided at both sides of the third display region DA3 along the second direction, that is, for the third display region DA3, If the number of fourth display regions DA4 adjacent to the third display region DA3 is two, the third display region DA3 includes two first row units R1, and each first row unit R1 is disposed corresponding to one adjacent fourth display region DA4.
In some embodiments, all third data sub-lines 113 electrically connected to all the second data sub-lines 112 in a same fourth display region DA4 are all located at the first side E1 of the first row unit R1 adjacent to the fourth display region DA4.
In some embodiments, a first boundary line F1 is formed between each third display region DA3 and the first display region DA1. Between each third display region DA3 and the first display region DA1, multiple first pixel circuits C1 corresponding to multiple first light-emitting elements P1 arranged in sequence along a direction away from the first boundary line F1 are sequentially arranged in the third display region DA3 in a direction away from the first boundary line F1.
As shown in
In the embodiments shown in
As shown in
In some embodiments, for each third display region DA3, the number of fourth display regions DA4 adjacent to the third display region DA3 is one. In the third display region DA3, the second connection points D2 in the first row unit R1 adjacent to the fourth display region DA4 are all located at the second side E2, so that multiple connection lines CL connected to the first row unit R1 are all located at a side of the first row unit R1 away from the fourth display region DA4. In some embodiments, in the third display region DA3, multiple connection lines CL connected to each of the remaining row units RX are all located at a side of the row unit RX facing the fourth display region DA4. In some other embodiments, in the third display region DA3, among the remaining row units RX, multiple connection lines CL connected to at least some of the row units RX are located at a side of the row unit RX away from the fourth display region DA4. In one embodiment, multiple connection lines CL connected to each row unit RX in the third display region DA3 are located at a side of the row unit RX away from the fourth display region DA4, so that the connection lines CL corresponding to the two row units RX are not arranged between adjacent row units RX, and the spacing between the row units RX is more balanced.
In some embodiments, at least one first pixel circuit C1 in the first row unit R1 is mirrored with at least one first pixel circuit C1 in the remaining row unit RX about a predetermined symmetry axis, and the predetermined symmetry axis is parallel to the first direction X. For example, in some embodiments, multiple row units RX include the first row unit R1 and the second row unit R2, the first pixel circuit C1 in the first row unit R1 is mirrored with the first pixel circuit C1 in the second row unit R2 about a predetermined symmetry axis, and the predetermined symmetry axis is parallel to the first direction X. For example, in the first pixel circuit C1 of the second row unit R2, the second connection point D2 is located at a lower side of the first pixel circuit C1 along the second direction Y, and in the first pixel circuit C1 of the first row unit R1, the second connection point D2 is located at an upper side of the first pixel circuit C1 along the second direction Y. Compared with the first pixel circuits C1 in the remaining row units RX, the at least one first pixel circuit C1 in the first row unit R1 is equivalent to being inverted along the second direction X, which is convenient to set the corresponding second connection point D2 at a side away from the fourth display region DA4, and the possibility of crossing between the connection line CL and the first data line 110 is reduced.
In the embodiments shown in
One embodiment of the present disclosure further provides a display apparatus including a display panel 100 according to any one of the above-mentioned embodiments of the present disclosure. The display panel 100 includes a first display region DA1, a second display region DA2, a third display region DA3, and a fourth display region DA4. The third display region DA3 is located at least one side of the first display region DA1 along a first direction X. The second display region DA2 at least partially surrounds the first display region DA1 and the third display region DA3. The first display region DA1 is reused into a photosensitive element integration region. The fourth display region DA4 is located between the third display region DA3 and the second display region DA2, and between the first display region DA1 and the second display region DA2, along a second direction Y, and the second direction Y intersects the first direction X.
The display panel 100 further includes a first pixel circuit C1 and a first light-emitting element P1 that are electrically connected to each other, a second pixel circuit C2 and a second light-emitting element P2 that are electrically connected to each other, a third pixel circuit C3 and a third light-emitting element P3 that are electrically connected to each other, a fourth pixel circuit C4 and a fourth light emitting element P4 that are electrically connected to each other.
The first light-emitting element P1 is located in the first display region DA1, and the first pixel circuit C1 is located in the third display region DA3. Each first pixel circuit C1 is electrically connected to at least one first light-emitting element P1 through corresponding connection lines CL. The second pixel circuit C2 and the second light emitting element P2 that are electrically connected to each other are located in the second display region DA2. The third pixel circuit C3 and the third light emitting element P3 that are electrically connected to each other are located in the third display region DA3. The fourth pixel circuit C4 and the fourth light-emitting element P4 that are electrically connected to each other are located in the fourth display region DA4.
The fourth pixel circuits C4 are arranged in at least one row in the fourth display region DA4. Each row of the fourth pixel circuits C4 includes at least one first arrangement unit U1 arranged along the first direction X. Each first arrangement unit U1 includes N fourth pixel circuits C4 and a first interval space K1, where N is a positive integer. The N fourth pixel circuits C4 are sequentially arranged adjacent to each other along the first direction X, and the first interval space K1 is located at a side of the N fourth pixel circuits C4 along the first direction X.
The display panel 100 further includes multiple first data lines 110. Each first data lines 110 is electrically connected to at least one first pixel circuit C1 and at least one second pixel circuit C2. At least one first data line 110 passes through the first interval space K1, so that the orthographic projections of multiple first data lines 110 on the display surface do not overlap with the orthographic projections of the connecting lines CL on the display surface.
With the display apparatus according to the embodiments of the present disclosure, in the display panel 100, the fourth pixel circuits C4 are arranged in at least one row in the fourth display region DA4, and each row of the fourth pixel circuits C4 includes first arrangement units U1. Each first arrangement unit U1 includes the first interval space K1, that is, at least one pixel circuit in the fourth display region DA4 that is not connected to the light-emitting element is removed to obtain the first interval space K1. The first interval space K1 can be used as a wiring space for the first data lines 110, and at least one first data line 110 passes through the first interval space K1, thereby reducing or even preventing the first data lines 110 from passing through the first display region DA1. The orthographic projection of a data line 110 on the display surface does not overlap with the orthographic projection of the connection line CL on the display surface, so as to avoid that the connection line CL affects the first data line 110. In this case, a load difference between the part of the first data line 110 in the third display region DA3 and the part of the first data line 110 in the second display region DA2 is reduced, so that the brightness of the first light-emitting element P1 tends to be the same as that of the second light-emitting element P2, thereby improving the uniformity of the display brightness of the display panel 100 and the display apparatus.
In accordance with the embodiments of the present disclosure as described above, these embodiments do not exhaustively describe all the details and do not limit only the embodiments described. Many modifications and variations can be made in light of the above description. These embodiments are selected and described in this specification to better explain the principle and practical application of the present disclosure, so that those skilled in the art can make good use of the present disclosure and modifications based on the present disclosure. The present disclosure is to be limited only by the claims, their full scope and equivalents.
