The display substrate includes a cutting area and a non-cutting area, and the non-cutting area includes a plurality of identical pixel areas arranged in an array, and one pixel area corresponds to one pixel. By setting the topological structure area of ​​the pixel in the pixel area adjacent to the cutting area to be smaller than the area of ​​the corresponding pixel area, the center of the pixel deviates from the center of the corresponding pixel area and is away from the corresponding cutting area and is close to the pixel area adjacent to it, wherein the pixel includes a light-emitting device, a driving circuit for driving the light-emitting device to emit light, and a signal line for providing the signal required by the driving circuit, so that each edge pixel in the pixel array is far away from the cutting path, and the light-emitting device, driving circuit and connected signal line of each edge pixel are far away from the cutting path, thereby better avoiding the metal film layer from falling off, the overlapping metal film layer short-circuiting and the cutting edge collapse during cutting.

Description

Technical Field

[0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display substrate and a display panel. Background Art

[0002] Light-emitting diodes (LEDs) are semiconductor electronic components that convert electrical energy into light. Due to their small size, long lifespan, rich colors, and low energy consumption, they are widely used in lighting, display screens, backlighting, and other fields. Mini LEDs, also known as sub-millimeter light-emitting diodes, typically measure 80 to 200 microns. They are a new generation of LED technology that inherits the high efficiency, high reliability, high brightness, and fast response time of fine-pitch LEDs, while also reducing power consumption and cost.

[0003] Before multiple Mini LED display substrates can be spliced ​​together without borders, the borders on each display substrate need to be removed first. However, whether it is cut by a cutter wheel or laser cutting, there is a certain degree of precision. In the design of traditional display substrates, the metal routing design of all pixels in the pixel array is the same. When cutting near the edge pixels, it is often easy to cause the metal film layer to fall off or the overlapping metal film layer to short-circuit, thereby affecting the yield rate of the display substrate after cutting; furthermore, the layout and arrangement of all pixels in the pixel array are the same. Therefore, when cutting a small-pitch LED display substrate, there is bound to be a problem of insufficient safety distance for the cutting path (including cutter wheel cutting or laser cutting, etc.), which is easy to cause the edge pixels to be missing or damaged due to edge collapse.

[0004] For example, Figure 1 This is a top view of the structure of a traditional display substrate. Figure 1 The display substrate includes a frame 01 and a pixel array located within the frame 01. The metal routing design of all pixels in the pixel array is the same. When cutting near the edge pixel 001, it is easy to cause the metal film layer of the metal routing 02 to fall off or the metal film layer of 002 at the overlap. The layout and arrangement of all pixels in the pixel array are the same. The cutting path safety distance is insufficient, which can easily cause the edge pixels 001 to be missing or damaged due to edge chipping. Summary of the Invention

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0041] Figure 2 is a schematic diagram of a top view of a display substrate provided by an embodiment of the present invention, with reference to Figure 2 The display substrate includes: a cutting area AA and a non-cutting area NAA, and the cutting area AA is arranged around the non-cutting area NAA; the non-cutting area NAA includes a plurality of identical pixel areas 200 arranged in an array, and one pixel area 200 corresponds to one pixel 500; the topological structure area of ​​the pixel 500 in the pixel area 200 adjacent to the cutting area AA is smaller than the area of ​​the corresponding pixel area 200, and the center of the pixel 500 deviates from the center of the corresponding pixel area 200 and is away from the corresponding cutting area AA and close to the pixel area 200 adjacent thereto; the topological structure area of ​​the pixel 500 in the pixel area 200 not adjacent to the cutting area AA is equal to the area of ​​the corresponding pixel area 200, and the center of the pixel 500 coincides with the center of the corresponding pixel area 200; wherein, the pixel 500 includes a light-emitting device, a driving circuit for driving the light-emitting device to emit light, and a signal line 300 for providing a signal required by the driving circuit.

[0042] Specifically, the display substrate can be divided into a cutting area AA and a non-cutting area AAN by the cutting streets 100 . The cutting area AA is an area of ​​the display substrate that needs to be removed, and serves as a frame of the display substrate.

[0043] A plurality of pixels 500 arranged in an array are disposed within a frame, with one pixel 500 occupying one pixel region 200. That is, the pixel region 200 is the region of the display substrate used to dispose the pixel 500. Two adjacent pixel regions 200 are connected; two pixel regions 200 being identical means that the two pixel regions 200 have the same area, i.e., the two pixel regions 200 occupy the same area of ​​the display substrate. Figure 2 The shape of the pixel region 200 is exemplarily shown as a rectangle, and this embodiment does not limit the shape of the pixel region 200.

[0044] Pixel 500 includes a light emitting device ( Figure 2 The light emitting device is, for example, an LED chip. The driving circuit is, for example, a TFT (Thin Film Transistor) pixel driving circuit. Figure 2 The exemplary drive unit 400 shown in FIG. 1 is composed of all the drive circuits of a pixel 500. For example, if a pixel 500 includes three LED chips, the pixel 500 includes three drive circuits. These three drive circuits constitute a drive unit 400, where one drive circuit drives each LED chip to emit light. The signal lines 300 may include scan signal lines, data signal lines, power signal lines, initialization signal lines, and light-emission control signal lines. The signal lines 300 are further divided into row signal lines 310 and column signal lines 320.

[0045] The pixel area adjacent to the cutting area AA can be understood as the pixel area next to the cutting area AA, that is, the pixel area next to the border, that is, the edge pixel area in the plurality of pixel areas arranged in an array, and the edge pixel area corresponds to the edge pixel. Figure 2 , Figure 2 4×4=16 pixel areas are exemplarily illustrated in the figure. Pixel areas adjacent to the cutting area AA are, for example, pixel area 200_1, pixel area 200_2, pixel area 200_3, pixel area 200_4, pixel area 200_5, pixel area 200_6, pixel area 200_7, pixel area 200_8, pixel area 200_9, pixel area 200_10, pixel area 200_11, and pixel area 200_12; pixel areas not adjacent to the cutting area AA are, for example, pixel area 200_13, pixel area 200_14, pixel area 200_15, and pixel area 200_16.

[0046] The topological area of ​​a pixel refers to the area of ​​a closed figure with the largest area formed by connecting the two ends of the two furthest-separated row signal lines and the two ends of the two furthest-separated column signal lines in the pixel area corresponding to the pixel. This area can cover the area of ​​the signal lines themselves. For example, refer to Figure 2The topological structure area of ​​pixel 500_2 is the area of ​​the largest closed figure formed by linearly connecting the two ends of the two furthest-separated row signal lines 310 and the two furthest-separated column signal lines 320 within the pixel region 200_2 corresponding to pixel 500_2. This area also covers the area of ​​the signal lines themselves. The topological structure area of ​​pixel 500_1 is the area of ​​the largest closed figure formed by linearly connecting the two ends of the two furthest-separated row signal lines 310 and the two furthest-separated column signal lines 320 within the pixel region 200_1 corresponding to pixel 500_1. This area also covers the area of ​​the signal lines themselves. Figure 2 The signal line 300 shown in FIG is an equivalent signal line, which may be composed of one or more actual signal lines. Figure 2 In the figure, two different filling patterns are used to illustrate two row signal lines 310 connecting a row of pixels 500, and one filling pattern is used to illustrate two column signal lines 320 connecting a column of pixels 500.

[0047] The center of a pixel refers to the center of its topological structure. The topological structure of a pixel is defined as the maximum area of ​​a closed figure formed by connecting the two ends of the two furthest-separated row signal lines and the two ends of the two furthest-separated column signal lines within the pixel region corresponding to the pixel. The center of this closed figure with the largest area is the center of the pixel's topological structure, and the area of ​​this closed figure with the largest area is also the pixel's topological structure area.

[0048] Based on the above, in the embodiment of the present invention, the topological structure area of ​​the pixels in the pixel area not adjacent to the cutout area AA is equal to the area of ​​the corresponding pixel area, and the center of the pixel coincides with the center of the corresponding pixel area. That is, compared with the traditional display substrate, the layout, arrangement and routing design of the pixels in the pixel area not adjacent to the cutout area AA are not changed, and remain the same. For example, continue to refer to Figure 2 The pixel area 200_14 is not adjacent to the cutting area AA, the topological structure area of ​​the pixels in the pixel area 200_14 is equal to the area of ​​the pixel area 200_14, and the center of the pixel coincides with the center of the pixel area 200_14.

[0049] The topological structure area of ​​the pixels in the pixel area adjacent to the cutting area AA is smaller than the area of ​​the corresponding pixel area, and the center of the pixel deviates from the center of the corresponding pixel area and is set away from the corresponding cutting area AA and close to the adjacent pixel area. That is, compared with the traditional display substrate, the layout, arrangement and routing design of the pixels in the pixel area adjacent to the cutting area AA are changed. The change is to reduce the topological structure area of ​​the pixel, and set the center of the pixel to be away from the cutting area AA and close to the pixel area adjacent to the pixel when it deviates from the center of the pixel area, so that the pixel in the pixel area adjacent to the cutting area AA is farther away from the cutting area AA, and the pixel's light-emitting device, driving circuit and signal line are all farther away from the cutting area AA, that is, the light-emitting device, driving circuit and signal line of the edge pixel are all farther away from the cutting road 100, and a relatively sufficient safety distance is reserved for the cutting road 100, thereby better avoiding the metal film layer of the signal line of the edge pixel falling off, the overlapping metal film layer short-circuiting and the cutting edge breaking when cutting the cutting area AA. The embodiment of the present invention thereby improves the cutting yield of the display substrate and ensures that the structure of the edge pixel is not damaged.

[0050] For example, continue to refer to Figure 2 The topological area of ​​pixel 500_1 is smaller than the area of ​​pixel region 200_1. The center of pixel 500_1 is offset from the center of pixel region 200_1 and away from cutting area AA. It is located closer to adjacent pixel regions 200_2 and 200_12, that is, closer to pixel region 200_13. This arrangement significantly distances pixel 500_1 from dicing street 100, leaving a larger clearance area between dicing street 100 and pixel 500_1. This provides a sufficient safety distance for dicing street 100. Therefore, when dicing area AA along dicing street 100 is removed, the metal film layer of signal line 300 connected to pixel 500_1 is effectively prevented from falling off, shorting of overlapping metal film layers, and edge chipping.

[0051] You can also compare Figure 2 and Figure 1 , compared to Figure 1 , Figure 2 The middle edge pixels are obviously farther away from the cutting road 100, and the empty area between the cutting road 100 and the edge pixels is larger, which can leave a sufficient safety distance for the cutting road 100. Therefore, when the cutting area AA is cut along the cutting road 100, the metal film layer of the signal line of the edge pixel can be better avoided from falling off, the overlapping metal film layer short-circuiting, and the cutting edge breaking.

[0052] To sum up, the display substrate provided by the embodiment of the present invention maintains the original layout, arrangement and routing design of the pixels in the pixel area not adjacent to the cutting area, and the topological structure area of ​​the pixel is equal to the area of ​​the corresponding pixel area, and the center of the pixel coincides with the center of the corresponding pixel area; while the layout, arrangement and routing design of the pixels in the pixel area adjacent to the cutting area are redesigned, which reduces the topological structure area of ​​the pixel, and sets the center of the pixel away from the cutting area and close to the pixel area adjacent to the pixel when it deviates from the center of the pixel area; thereby, it can better avoid the metal film layer of the signal line of the edge pixel from falling off, the overlapping metal film layer short-circuiting and the cutting edge breaking when the cutting area is cut off, thereby ensuring that the structure of the edge pixel is not damaged.

[0053] In addition, for the layout, arrangement and routing design of pixels in the pixel area adjacent to the cutting area, the degree of reduction in the topological structure area of ​​the specific pixel, the degree to which the center of the pixel deviates from the center of the pixel area, and the degree to which the center of the pixel is away from the cutting area and close to the pixel area adjacent to the pixel can all be set according to the needs of actual conditions, ensuring that the edge pixels are as far away from the cutting path as possible without affecting other settings.

[0054] In the above embodiment, the display substrate may be composed of a driving substrate and a light-emitting substrate. The light-emitting substrate is disposed on the driving substrate, and multiple identical pixel regions arranged in an array are located in the non-cutting area of ​​the light-emitting substrate and the driving substrate. The frame of the display substrate is located in the cutting area of ​​the light-emitting substrate and the driving substrate.

The light-emitting substrate includes 4 rows and 4 columns of pixel areas, that is, 4 rows and 4 columns of pixels, and 4 rows and 4 columns of light-emitting units. Each light-emitting unit includes 3 light-emitting devices 600. The 3 light-emitting devices 600 are regarded as a whole, and the center of the whole is the center of the light-emitting unit.

[0057] Continue to refer Figure 3For example, the center of the light-emitting unit formed by all the light-emitting devices in the pixel region 200_1 of the first row and the first column is located near the pixel region of the second row and the second column; the center of the light-emitting unit formed by all the light-emitting devices in the pixel region of the first row and the fourth column is located near the pixel region of the second row and the third column; the center of the light-emitting unit formed by all the light-emitting devices in the pixel region of the fourth row and the first column is located near the pixel region of the third row and the second column; and the center of the light-emitting unit formed by all the light-emitting devices in the pixel region of the fourth row and the fourth column is located near the pixel region of the third row and the third column. This embodiment of the present invention is configured so that the light-emitting devices at the four corners of the light-emitting substrate are all far away from the cutting path. The light-emitting devices at the four corners avoid the cutting tool and are located within a safe distance from the cutting path, thereby ensuring that the light-emitting devices at the four corners of the light-emitting substrate are protected from damage when the display substrate is cut.

[0058] On the basis of the above technical solution, in one embodiment of the present invention, optionally, the center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the Lth row and the 1st column is arranged close to the pixel area of ​​the Lth row and the 2nd column.

The embodiment of the present invention is configured so that each light-emitting device located on the four sides of the light-emitting substrate is far away from the cutting path. Each light-emitting device located on the four sides avoids the cutting tool at a distance and is within a safe distance of the cutting path, thereby ensuring that each light-emitting device on the four sides of the light-emitting substrate is protected from damage when the display substrate is cut.

[0060] As can be seen from the above, the specific positions of the light-emitting devices on the light-emitting substrate in the above technical solution can be understood as dividing the light-emitting substrate into multiple regions and then arranging the specific positions of the light-emitting devices according to the regions. For example, the light-emitting substrate is divided into a first region in the middle, a second region on the upper side, a third region on the lower side, a fourth region on the left side, a fifth region on the right side, a sixth region in the upper left corner, a seventh region in the upper right corner, an eighth region in the lower left corner, and a ninth region in the lower right corner.

The center of the light-emitting unit composed of all light-emitting devices in the pixel area of ​​the Lth row and the Kth column coincides with the center of the pixel area of ​​the Lth row and the Kth column.

The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the Mth row and the Kth column is arranged close to the pixel area of ​​the (M-1)th row and the Kth column, so that the light-emitting devices in the pixels of the Mth row and the Kth column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0065] For example, in combination Figure 3 and Figure 7 , Figure 7 This is a schematic diagram of the position setting of the light-emitting devices in the fourth area on the left side of the light-emitting substrate provided in an embodiment of the present invention. The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the Lth row and the first column is set close to the pixel area of ​​the Lth row and the second column, so that the light-emitting devices in the pixels of the Lth row and the first column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0066] For example, in combination Figure 3 and Figure 8 , Figure 8 This is a schematic diagram of the position setting of the light-emitting devices in the fifth area on the right side of the light-emitting substrate provided in an embodiment of the present invention. The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the Lth row and the Nth column is set close to the pixel area of ​​the Lth row and the (N-1)th column, so that the light-emitting devices in the pixels of the Lth row and the Nth column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0067] For example, in combination Figure 3 and Figure 9 , Figure 9 This is a schematic diagram of the position setting of the light-emitting devices in the sixth area in the upper left corner of the light-emitting substrate provided by an embodiment of the present invention. The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the 1st row and the 1st column is set close to the pixel area of ​​the 2nd row and the 2nd column, so that the light-emitting devices in the pixels of the 1st row and the 1st column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0068] For example, in combination Figure 3 and Figure 10 , Figure 10 This is a schematic diagram of the position setting of the light-emitting devices in the seventh area in the upper right corner of the light-emitting substrate provided by an embodiment of the present invention. The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the 1st row and the Nth column is set close to the pixel area of ​​the 2nd row and the (N-1)th column, so that the light-emitting devices in the pixels of the 1st row and the Nth column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0069] For example, in combination Figure 3 and Figure 11 , Figure 11 This is a schematic diagram of the position setting of the light-emitting devices in the eighth area in the lower left corner of the light-emitting substrate provided by an embodiment of the present invention. The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the Mth row and the first column is set close to the pixel area of ​​the (M-1)th row and the second column, so that the light-emitting devices in the pixels of the Mth row and the first column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0070] For example, in combination Figure 3 and Figure 12 , Figure 12 This is a schematic diagram of the position setting of the light-emitting devices in the ninth area in the lower right corner of the light-emitting substrate provided by an embodiment of the present invention. The center of the light-emitting unit composed of all the light-emitting devices in the pixel area of ​​the Mth row and Nth column is set close to the pixel area of ​​the (M-1)th row and (N-1)th column, so that the light-emitting devices in the pixels of the Mth row and Nth column are far away from the cutting path and are located within the safe cutting distance, which can avoid damage during cutting.

[0071] In the above technical solution, the embodiment of the present invention makes a new setting for the specific arrangement position of the light-emitting devices at the four corners and along the four sides of the light-emitting substrate on the base substrate, so that the light-emitting devices at the four corners and along the four sides of the light-emitting substrate are all away from the cutting path, within a safe distance from the cutting path, and far away from the cutting path, thereby ensuring that the light-emitting devices at the four corners and along the four sides of the light-emitting substrate are protected from damage when cutting the display substrate. On this basis, the arrangement of the light-emitting devices in the light-emitting units at the four corners and along the four sides of the light-emitting substrate can be various. The following examples illustrate several of them, but they are not intended to limit the present invention.

[0072] On the basis of the above technical solution, in one embodiment of the present invention, optionally, the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the 1st row and the 1st column, the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the 1st row and the Nth column, the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the Mth row and the 1st column, and the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the Mth row and the Nth column are all the first arrangement mode; the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the 2nd row to the (M-1)th row and the 1st column and the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the 2nd row to the (M-1)th row and the Nth column are all the second arrangement mode; the arrangement mode of the multiple light-emitting devices in the pixel area of ​​the 1st row to the Mth row and the 2nd column to the (N-1)th column are all the third arrangement mode; the first arrangement mode, the second arrangement mode and the third arrangement mode are different from each other.

[0073] The pixel includes three light-emitting devices, namely a first light-emitting device, a second light-emitting device, and a third light-emitting device. The first light-emitting device can be a red light-emitting device, a green light-emitting device, or a blue light-emitting device. Correspondingly, the second light-emitting device can be a green light-emitting device, a blue light-emitting device, or a red light-emitting device. The third light-emitting device can be a blue light-emitting device, a red light-emitting device, or a green light-emitting device. The following uses the first light-emitting device 600_R, the second light-emitting device 600_G, and the third light-emitting device 600_B as examples to illustrate the technical solutions of the embodiments of the present invention, but does not limit the present invention. The direction from the 1st column to the Nth column is the row arrangement direction X, and the direction from the 1st row to the Mth row is the column arrangement direction Y. In the embodiments of the present invention, the arrangement direction of the light-emitting devices is parallel to the length direction or long axis direction of the light-emitting devices.

[0077] The arrangement of the light-emitting devices provided in the embodiment of the present invention enables the light-emitting devices at the four corners and along the four sides of the light-emitting substrate to be away from the cutting path, within a safe distance from the cutting path, and farther away from the cutting path, thereby ensuring that the light-emitting devices at the four corners and along the four sides of the light-emitting substrate are protected from damage when the display substrate is cut. In addition, the embodiment of the present invention uses light-emitting devices with a length or a long axis as an example, such as a light-emitting device that is rectangular. Of course, the light-emitting device can also be in other shapes, such as a circle, triangle, rhombus, square, pentagon, hexagon or other regular or irregular shapes. For such shapes, the light-emitting device may not have a length or a long axis. Then, when designing the arrangement of the light-emitting devices, only the arrangement order between each other can be considered without considering the setting direction of the light-emitting devices, and it will not affect the display substrate to achieve the above-mentioned technical effects.

[0078] On the basis of the above technical solution, in another embodiment of the present invention, optionally, referring to Figure 13 , Figure 13 This is a schematic diagram of the top structure of another light-emitting substrate provided by an embodiment of the present invention. The arrangement of the multiple light-emitting devices in the pixel area 200_1 of the 1st row and the 1st column and the arrangement of the multiple light-emitting devices in the pixel area of ​​the Mth row and the 1st column are both the first arrangement of the above embodiment; the arrangement of the multiple light-emitting devices in the pixel area of ​​the 1st row and the Nth column and the arrangement of the multiple light-emitting devices in the pixel area of ​​the Mth row and the Nth column are both the fourth arrangement; the arrangement of the multiple light-emitting devices in the pixel area from the 2nd row to the (M-1)th row and the 1st column and the arrangement of the multiple light-emitting devices in the pixel area from the 2nd row to the (M-1)th row and the Nth column are both the fifth arrangement; the arrangement of the multiple light-emitting devices in the pixel area from the 1st row to the Mth row and the 2nd column to the (N-1)th column are both the third arrangement of the above embodiment; the fourth arrangement, the fifth arrangement, the first arrangement of the above embodiment, the second arrangement of the above embodiment and the third arrangement of the above embodiment are different from each other.

[0079] Among them, continue to refer to Figure 13The pixels in the 1st row and 1st column, the pixels in the 1st row and Nth column, the pixels in the Mth row and 1st column, the pixels in the Mth row and Nth column, and the pixels in the 1st to Mth rows and the 2nd to (N-1)th columns all include three light-emitting devices, which are a first light-emitting device, a second light-emitting device, and a third light-emitting device. The first light-emitting device may be a red light-emitting device, a green light-emitting device or a blue light-emitting device. Accordingly, the second light-emitting device may be a green light-emitting device, a blue light-emitting device or a red light-emitting device. The third light-emitting device may be a blue light-emitting device, a red light-emitting device or a green light-emitting device. The following uses the first light-emitting device, the second light-emitting device and the third light-emitting device as red light-emitting device 600_R, green light-emitting device 600_G and blue light-emitting device 600_B as examples to illustrate the technical solution of the embodiment of the present invention, but does not serve as a limitation of the present invention. Optionally, in the fourth arrangement, the setting direction of the first light-emitting device is along the column arrangement direction, the setting direction of the second light-emitting device and the setting direction of the third light-emitting device are both along the row arrangement direction, and the second light-emitting device and the third light-emitting device are both located to the left of the first light-emitting device along the row arrangement direction.

[0080] On this basis, continue to refer to Figure 13 , the pixels from the 2nd row to the (M-1)th row and the 1st column and the pixels from the 2nd row to the (M-1)th row and the Nth column all include four light-emitting devices, and the four light-emitting devices are respectively a first light-emitting device, a first second light-emitting device, a second second light-emitting device and a third light-emitting device. The first second light-emitting device and the second second light-emitting device can both be red light-emitting devices, green light-emitting devices or blue light-emitting devices. The first light-emitting device, the first second light-emitting device, the second second light-emitting device and the third light-emitting device are respectively a red light-emitting device 600_R, a first green light-emitting device 600_G1, a second green light-emitting device 600G_2 and a blue light-emitting device 600_B; optionally, in the fifth arrangement mode, the setting direction of the first light-emitting device and the setting direction of the third light-emitting device are both along the row arrangement direction, and the first light-emitting device and the second light-emitting device are arranged in sequence along the column arrangement direction, the first second light-emitting device and the second second light-emitting device are arranged in sequence along the row arrangement direction and are both located between the first light-emitting device and the second light-emitting device.

[0081] Specifically, with Figure 3 The difference is, Figure 13The fourth arrangement is adopted, which is mirror-symmetrical to the first arrangement of the above embodiment. With this arrangement, when two display substrates whose cutting areas have been removed are spliced ​​together, the pixels arranged in the first arrangement of one display substrate can borrow sub-pixels from the pixels arranged in the fourth arrangement of the other display substrate (one light-emitting device is one sub-pixel), thereby avoiding the problem that the spacing between pixels at the splicing position is significantly different from the spacing between pixels within the array, which affects the display effect, and ensuring a good display effect after splicing. For example, referring to Figure 14 , Figure 14 This is a schematic diagram of the top-down structure of the light-emitting substrates when two display substrates provided in an embodiment of the present invention are spliced ​​together. The borders of the two display substrates have been cut off, and the second light-emitting devices and the third light-emitting devices in the pixels arranged in the first arrangement of one of the display substrates are shared by the red light-emitting devices in the pixels arranged in the fourth arrangement of the other display substrate; at the same time, the red light-emitting devices in the pixels arranged in the first arrangement of one of the display substrates are shared by the green light-emitting devices and the blue light-emitting devices in the pixels arranged in the fourth arrangement of the other display substrate.

[0082] and Figure 3 What is different is that Figure 13 The fifth arrangement is adopted. Compared with the second arrangement, a pixel in the fifth arrangement includes two second light-emitting devices, namely the first second light-emitting device and the second second light-emitting device. Taking the first second light-emitting device as the first green light-emitting device 600_G1 and the second second light-emitting device as the second green light-emitting device 600_G2 as an example, the first green light-emitting device G1 and the second green light-emitting device G2 are independently controlled; and the first green light-emitting device G1 and the second green light-emitting device G2 are the same size, and both are smaller than the size of the green light-emitting device in the second arrangement. In this way, when the two display substrates whose cutting areas have been cut off are spliced, the pixels arranged in the fifth arrangement of one of the display substrates can borrow sub-pixels from each other with the pixels arranged in the fifth arrangement of the other display substrate, thereby further avoiding the problem that the spacing between pixels at the splicing position is not equal to the spacing between pixels within the array, which affects the display effect, and ensures a good display effect after splicing. For example, continue to refer to Figure 14, the first green light-emitting device G1 in the pixels arranged in the fifth arrangement of one display substrate is shared by the red light-emitting device, the blue light-emitting device and the second green light-emitting device G2 in the pixels arranged in the fifth arrangement of another display substrate; at the same time, the red light-emitting device, the blue light-emitting device and the second green light-emitting device G2 in the pixels arranged in the fifth arrangement of one display substrate share the first green light-emitting device G1 in the pixels arranged in the fifth arrangement of the other display substrate.

[0083] The arrangement of the light-emitting devices provided in the embodiment of the present invention ensures that the light-emitting devices at the four corners and along the four sides of the light-emitting substrate are all away from the cutting path, within a safe distance from the cutting path, and farther away from the cutting path, thereby ensuring that the light-emitting devices at the four corners and along the four sides of the light-emitting substrate are protected from damage when the display substrate is cut; at the same time, when two display substrates whose cutting areas have been cut off are spliced ​​together, it can also avoid the problem of the spacing between pixels at the splicing position being unequal to the spacing between pixels in the array, which affects the display effect, thereby ensuring a good display effect after splicing.

[0084] Based on the above technical solution, the driver circuits on the driver substrate are also positioned specifically according to the specific placement and arrangement of the light-emitting devices on the light-emitting substrate. This prevents the metal film layer of the signal lines of edge pixels from falling off and the overlapping metal film layers from shorting when the display substrate is cut. The driver substrate includes driver circuits distributed in an array. One driver circuit corresponds to one light-emitting device, that is, one driver circuit can drive one light-emitting device.

The center of the driving unit formed by all the driving circuits in the pixel area of ​​the Lth row and the Nth column is arranged close to the pixel area of ​​the Lth row and the (N-1)th column. In this case, the center of each driving circuit in the pixel area of ​​the Lth row and the Nth column can respectively be arranged close to the pixel area of ​​the Lth row and the (N-1)th column.

The embodiment of the present invention is thus arranged so that the driving circuits on the four sides of the driving substrate and the driving circuits at the four corners are all far away from the cutting path. The driving circuits on the four sides and the driving circuits at the four corners are all far away from the cutting tool and are within a safe distance from the cutting path, thereby ensuring that the driving circuits on the four sides and the driving circuits at the four corners of the driving substrate are protected from damage when the display substrate is cut.

This ensures that the metal film layer of the signal lines on the four edges and the four corners of the driver substrate will not fall off or the overlapping metal film layers will short-circuit when cutting the display substrate.

[0090] As can be seen from the above, the specific positions of the signal lines and driving circuits on the driving substrate in the above technical solution can be understood as dividing the driving substrate into multiple areas and then setting the specific positions of the signal lines and driving circuits according to the areas.
