Technical Field

[0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to an organic light-emitting display panel and a display device. Background Art

[0002] With the continuous development and improvement of display technologies, people's requirements for displays are getting higher and higher. Among them, organic light-emitting display devices have the advantages of self-luminescence, wide viewing angles, wide color gamuts, high luminous efficiencies, being ultra-thin and ultra-light, and low power consumption, and have been widely used. It can be understood that an organic light-emitting display device realizes image display through a plurality of pixels arranged in a matrix form, and different pixel arrangement methods will also have different effects on display brightness and display effects. Therefore, how to improve the display brightness and display effects of organic light-emitting display devices has become a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0003] The present invention provides a pixel circuit, a silicon-based display panel, and a display device to solve the problem that it is difficult to improve the display brightness and display effects of existing organic light-emitting display devices.

[0005] Each pixel unit includes four sub-pixels, namely a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The third sub-pixel and the fourth sub-pixel have the same light-emitting color, and any two of the first sub-pixel, the second sub-pixel, and the third sub-pixel have different light-emitting colors;

[0006] In the same pixel unit, along the first direction, the third sub-pixel overlaps with the first sub-pixel or the second sub-pixel, and the fourth sub-pixel overlaps with the second sub-pixel and does not overlap with the second sub-pixel; along the second direction, the first sub-pixel overlaps with the second sub-pixel, and the third sub-pixel overlaps with the fourth sub-pixel.

[0008] In the technical solution of the embodiment of the present invention, by providing a plurality of pixel units arranged along a first direction and a second direction, the first direction intersects with the second direction, and each pixel unit includes four sub-pixels, namely a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. Among them, the third sub-pixel and the fourth sub-pixel have the same emission color, and any two of the first sub-pixel, the second sub-pixel, and the third sub-pixel have different emission colors, so that the pixel unit performs image display according to the light emitted by the four sub-pixels. In the same pixel unit, along the first direction, the third sub-pixel overlaps with the first sub-pixel or the second sub-pixel, the fourth sub-pixel overlaps with the second sub-pixel, and does not overlap with the first sub-pixel; along the second direction, the first sub-pixel overlaps with the second sub-pixel, and the third sub-pixel overlaps with the fourth sub-pixel, which can make each sub-pixel have a high space utilization rate, so as to improve the aperture utilization rate of the entire pixel unit and ensure that the organic light-emitting display panel has a high display quality.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0026] Figure 1A partial structural diagram of an organic light emitting display panel provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the organic light emitting display panel includes a plurality of pixel units 10 arranged along a first direction X and a second direction Y, and the first direction X intersects with the second direction Y. The pixel unit 10 includes four sub-pixels, and the four sub-pixels are a first sub-pixel 11, a second sub-pixel 12, a third sub-pixel 13 and a fourth sub-pixel 14. The third sub-pixel 13 and the fourth sub-pixel 14 have the same luminous color. Any two of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 have different luminous colors. In the same pixel unit 10, along the first direction X, the third sub-pixel 13 overlaps with the first sub-pixel 11 or the second sub-pixel 12 ( Figure 1 In the figure, the third sub-pixel 13 overlaps with the first sub-pixel 11 as an example for illustration). Along the first direction X, the fourth sub-pixel 14 overlaps with the second sub-pixel 12, and does not overlap with the first sub-pixel 11. Along the second direction Y, the first sub-pixel 11 overlaps with the second sub-pixel 12, and the third sub-pixel 13 overlaps with the fourth sub-pixel 14. In various embodiments of the present invention, the overlap of two sub-pixels along a certain direction means that the two sub-pixels are arranged along the direction.

[0027] It is understood that the shape of the pixel unit 10 includes but is not limited to a rectangle, a circle or other polygonal shapes. Figure 1 The pixel unit 10 is only exemplarily shown as a rectangular structure diagram. Depending on the specific position of the pixel unit 10 in the organic light-emitting display panel, it can be set according to actual needs, and the embodiment of the present invention does not specifically limit this. In addition, the shape, area and relative position relationship of the four sub-pixels in the pixel unit 10 can also be set according to actual needs, and the embodiment of the present invention does not specifically limit this. Figure 1 It is shown for exemplary purposes only.

[0028] Among them, any two of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 have different luminescent colors, and the third sub-pixel 13 and the fourth sub-pixel 14 have the same luminescent color. The embodiment of the present invention does not limit the specific luminescent colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13, and can be set according to actual needs, for example, respectively selected from any one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Exemplarily, the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a green sub-pixel, and the third sub-pixel 13 and the fourth sub-pixel 14 are both blue sub-pixels.

[0029] Specifically, in the same pixel unit 10, along the first direction X, the third sub-pixel 13 overlaps with the first sub-pixel 11 or the second sub-pixel 12. It can be understood that along the first direction X, the third sub-pixel 13 can overlap only with the first sub-pixel 11 or only with the second sub-pixel 12. In other words, along the first direction X, the third sub-pixel 13 does not overlap with both the first sub-pixel 11 and the second sub-pixel 12. The fourth sub-pixel 14 overlaps with the second sub-pixel 12 and does not overlap with the first sub-pixel 11. Along the first direction X, the fourth sub-pixel 14 does not overlap with both the first sub-pixel 11 and the second sub-pixel 12. Along the second direction Y, the first sub-pixel 11 overlaps with the second sub-pixel 12, and the third sub-pixel 13 overlaps with the fourth sub-pixel 14. It can be seen that in the same pixel unit 10, along the first direction X, the third sub-pixel 13 can overlap with the first sub-pixel 11, and the fourth sub-pixel 14 can overlap with the second sub-pixel 12 (for reference, see Figure 1 shown). Or, in other embodiments, along the first direction X, neither the third sub-pixel 13 nor the fourth sub-pixel 14 overlaps with the first sub-pixel 11, that is, both the third sub-pixel 13 and the fourth sub-pixel 14 overlap with the second sub-pixel 12 (for reference, see Figure 2 shown, Figure 2 which is a schematic diagram of a partial structure of another organic light-emitting display panel provided by an embodiment of the present invention). Thus, through the above arrangement of the four sub-pixels in the pixel unit 10, it is realized that along the first direction X, the third sub-pixel 13 overlaps with only one of the first sub-pixel 11 and the second sub-pixel 12, and the fourth sub-pixel 14 overlaps only with the second sub-pixel 12, so that each sub-pixel has a high space utilization rate, thereby improving the aperture utilization rate of the entire pixel unit 10 and ensuring that the organic light-emitting display panel has a high display quality.

[0030] It should be noted that since there can be multiple actual arrangement ways of the four sub-pixels in the pixel unit 10, in the organic light-emitting display panel, the structures of multiple pixel units 10 arranged along the first direction X and the second direction Y can be completely the same or completely different, that is, it can be a combination of any two or more pixel units 10 with different sub-pixel arrangement structures, including but not limited to Figure 1 and Figure 2 shown in the arrangement structures of multiple pixel units 10. Those skilled in the art can set according to actual needs, and the embodiments of the present invention do not make specific limitations on this.

[0031] In addition, since the third sub-pixel 13 and the fourth sub-pixel 14 have the same emission color, the pixel driving circuits for driving the emission of the third sub-pixel 13 and the fourth sub-pixel 14 can share one or be independent. The embodiments of the present invention do not make specific limitations on this.

[0032] In the embodiments of the present invention, by arranging a plurality of pixel units arranged along a first direction and a second direction, the first direction intersects with the second direction. And each pixel unit includes four sub-pixels, namely a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. Among them, the third sub-pixel and the fourth sub-pixel have the same emission color, and any two of the first sub-pixel, the second sub-pixel, and the third sub-pixel have different emission colors, so that the pixel unit performs image display according to the light emitted by the four sub-pixels. In the same pixel unit, along the first direction, the third sub-pixel overlaps with the first sub-pixel or the second sub-pixel, and the fourth sub-pixel overlaps with the second sub-pixel and does not overlap with the first sub-pixel. Along the second direction, the first sub-pixel overlaps with the second sub-pixel, and the third sub-pixel overlaps with the fourth sub-pixel, which can make each sub-pixel have a high space utilization rate. In this way, the aperture utilization rate of the entire pixel unit can be improved, ensuring that the organic light-emitting display panel has a high display quality.

[0033] Optionally, continue to refer to Figure 1 As shown, the first sub-pixel 11 includes a first sub-pixel upper edge 111 and a first sub-pixel lower edge 112. Along the second direction Y, the first sub-pixel lower edge 112 is located between the first sub-pixel upper edge 111 and the second sub-pixel 12. Along the second direction Y, the fourth sub-pixel 14 is located on the side of the first sub-pixel lower edge 112 away from the first sub-pixel upper edge 111. Along the first direction X, the fourth sub-pixel 14 does not overlap with the first sub-pixel 11, and the fourth sub-pixel 14 does not overlap with both the first sub-pixel 11 and the second sub-pixel 12.

[0034] It can be understood that the first sub-pixel lower edge 112 is located between the first sub-pixel upper edge 111 and the second sub-pixel 12, that is, the second sub-pixel 12 is located on the side of the first sub-pixel lower edge 112 away from the first sub-pixel upper edge 111, and there is a certain distance between the second sub-pixel 12 and the first sub-pixel lower edge 112. This distance can be zero or any value greater than zero. The fourth sub-pixel 14 is located on the side of the first sub-pixel lower edge 112 away from the first sub-pixel upper edge 111, that is, there is a certain distance between the fourth sub-pixel 14 and the first sub-pixel 11. This distance can be zero or any value greater than zero. The embodiments of the present invention do not make any limitations on the distances between the second sub-pixel 12 and the first sub-pixel lower edge 112 and between the fourth sub-pixel 14 and the first sub-pixel 11, and can be set according to actual needs.

[0035] Optionally, Figure 3 is a partial structural schematic diagram of another organic light-emitting display panel provided by the embodiments of the present invention. As shown in Figure 3As shown, the length of the first sub-pixel 11 along the second direction Y is L1, the length of the second sub-pixel 12 along the second direction Y is L2, the length of the third sub-pixel 13 along the second direction Y is L3, and the length of the fourth sub-pixel 14 along the second direction Y is L4. The pixel unit 10 includes a first pixel unit 101. In the first pixel unit 101, along the second direction Y, the distance between the first sub-pixel 11 and the first boundary 101' of the first pixel unit 101 is a, the distance between the first sub-pixel 11 and the second sub-pixel 12 is 2a, the distance between the second sub-pixel 12 and the second boundary 101" of the first pixel unit 101 is a, the distance between the third sub-pixel 13 and the first boundary 101' is b, the distance between the third sub-pixel 13 and the fourth sub-pixel 14 is 2b, and the distance between the fourth sub-pixel 14 and the second boundary 101" is a + c. The first boundary 101' and the second boundary 101" are opposite to each other. The first pixel unit 101 satisfies: L3 < L1 + 3a - b, L4 < L2 + 2a - c.

[0036] Among them, the specific values of a, b, and c can be set according to actual needs, and the embodiments of the present invention do not make specific limitations thereon. Optionally, a < b < c.

[0037] Specifically, the length of the first sub-pixel 11 along the second direction Y is L1, and the distance between the first sub-pixel 11 and the first boundary 101' of the first pixel unit 101 is a, and the distance between the first sub-pixel 11 and the second sub-pixel 12 is 2a. Thus, the distance between the edge of the second sub-pixel 12 adjacent to the first sub-pixel 11 and the first boundary 101' of the first pixel unit 101 is L1 + 3a. The distance between the third sub-pixel 13 and the first boundary 101' is b, and the distance between the edge of the third sub-pixel 13 adjacent to the fourth sub-pixel 14 and the first boundary 101' is b + L3. Thus, when the first pixel unit 101 satisfies the relation L3 < L1 + 3a - b, it indicates that there is no overlap between the third sub-pixel 13 and the second sub-pixel 12 in the X direction. Along the first direction X, there is an overlap between the third sub-pixel 13 and the first sub-pixel 11. Along the second direction Y, the distance between the third sub-pixel 13 and the second sub-pixel 12 is the difference between (L1 + 3a - b) and L3. Moreover, the distance between the lower edge 112 of the first sub-pixel and the second boundary 101'' of the first pixel unit 101 is L2 + 3a, and the distance between the edge of the fourth sub-pixel 14 far from the third sub-pixel 13 and the second boundary 101'' of the first pixel unit 101 is a + c. Thus, when the first pixel unit 101 satisfies L4 < L2 + 2a - c, it indicates that there is no overlap between the fourth sub-pixel 14 and the first sub-pixel 11 in the X direction. Along the first direction X, there is an overlap between the fourth sub-pixel 14 and the second sub-pixel 12, and along the second direction Y, the distance between the fourth sub-pixel 14 and the first sub-pixel 11 is the difference between (L2 + 2a - c) and L4.

[0038] Optionally, continue to refer to Figure 3 As shown, the pixel unit 10 further includes a second pixel unit 102. In the second pixel unit 102, along the second direction Y, the distance between the first sub-pixel 11 and the third boundary 102' of the second pixel unit 102 is a, the distance between the first sub-pixel 11 and the second sub-pixel 12 is 2a, the distance between the second sub-pixel 12 and the fourth boundary 102'' of the second pixel unit 102 is a, the distance between the third sub-pixel 103 and the third boundary 102' is a + c, the distance between the third sub-pixel 13 and the fourth sub-pixel 14 is 2b, and the distance between the fourth sub-pixel 14 and the fourth boundary 102'' is b. The third boundary 102' is opposite to the fourth boundary 102''. The second pixel unit 102 satisfies: L1 < c, or L1 > c, L3 < L1 + 2a - c.

[0039] Specifically, the distance between the first sub-pixel 11 in the second pixel unit 102 and the third boundary 102' of the second pixel unit 102 is a, and the distance between the third sub-pixel 103 and the third boundary 102' is a + c. The distance from the lower edge of the first sub-pixel 11 to the third boundary 102' is L1 + a. In the second pixel unit 102, when the second pixel unit 102 satisfies L1 < c, it indicates that along the first direction X, there is no overlap between the third sub-pixel 13 and the first sub-pixel 11. The distance between the third sub-pixel 13 and the first sub-pixel 11 is the difference between c and L1.

[0040] Alternatively, in other embodiments, in the second pixel unit 102, when the second pixel unit 102 satisfies L1 > c, it indicates that along the first direction X, there is an overlap between the third sub-pixel 13 and the first sub-pixel 11. Since the distance between the second sub-pixel 14 in the second pixel unit 102 and the third boundary 102' is L1 + 3a, and the distance between the third sub-pixel 13 and the third boundary 102' is L3 + a + c, and the second pixel unit 102 further satisfies L3 < L1 + 2a - c, that is, along the first direction X, there is no overlap between the third sub-pixel 13 and the second sub-pixel 12, and the distance between the third sub-pixel 13 and the second sub-pixel 12 is the difference between L3 and (L1 + 2a - c).

[0041] Optionally, continue to refer to Figure 3 As shown, along the first direction X, there is one second pixel unit 102 between two adjacent first pixel units 101, and there is one first pixel unit 101 between two adjacent second pixel units 102. Along the second direction Y, there is one second pixel unit 102 between two adjacent first pixel units 101, and there is one first pixel unit 101 between two adjacent second pixel units 102. The second boundary 101” overlaps with the third boundary 102’. The first pixel units 101 and the second pixel units 102 are arranged at intervals one by one along the first direction X, and the first pixel units 101 and the second pixel units 102 are arranged at intervals one by one along the second direction Y.

[0042] It can be understood that according to different relationships of L1 < c, or L1 > c, L3 < L1 + 2a - c satisfied by the second pixel unit 102, the specific arrangement ways of the four sub-pixels in the second pixel unit 102 will also be different. Figure 3 Only an exemplary structural schematic diagram when the second pixel unit 102 satisfies L1 < c is shown, that is, in the second pixel unit 102, along the first direction X, there is no overlap between the third sub-pixel 13 and the first sub-pixel 11.

[0043] In other embodiments, the second pixel unit 102 may satisfy L1 > c and L3 < L1 + 2a - c, that is, along the first direction X, the third sub-pixel 13 may overlap with the first sub-pixel 11, and there is no overlap between the third sub-pixel 13 and the second sub-pixel 12. Those skilled in the art can make adaptive adjustments according to actual needs.

[0044] Optionally, Figure 4 FIG. is a partial structural schematic diagram of another organic light-emitting display panel provided by an embodiment of the present invention. As Figure 4 shown, the length of the first sub-pixel 11 along the second direction Y is L1, the length of the second sub-pixel 12 along the second direction Y is L2, the length of the third sub-pixel 13 along the second direction Y is L3, and the length of the fourth sub-pixel 14 along the second direction Y is L4. The pixel unit 10 includes a third pixel unit 103. In the third pixel unit 103, along the second direction Y, the distance between the first sub-pixel 11 and the fifth boundary 103' of the third pixel unit 103 is a, the distance between the first sub-pixel 11 and the second sub-pixel 12 is 2a, the distance between the second sub-pixel 12 and the sixth boundary 103" of the third pixel unit 13 is a, the distance between the third sub-pixel 13 and the fifth boundary 103' is a + c, the distance between the third sub-pixel 13 and the fourth sub-pixel 14 is 2b, and the distance between the fourth sub-pixel 14 and the sixth boundary 103" is a + c. The fifth boundary 103' and the sixth boundary 103" are opposite to each other. The third pixel unit 103 satisfies: L3 < L1 + 2a - c, L4 < L2 + 2a - c.

[0045] Specifically, in the third pixel unit 103, the length of the first sub-pixel 11 along the second direction Y is L1, and the distance between the first sub-pixel 11 and the fifth boundary 103' of the third pixel unit 103 is a, and the distance between the first sub-pixel 11 and the second sub-pixel 12 is 2a. Thus, the distance between the edge of the second sub-pixel 12 adjacent to the first sub-pixel 11 and the fifth boundary 103' of the third pixel unit 103 is L1 + 3a. The distance between the edge of the third sub-pixel 13 away from the fourth sub-pixel 14 and the fifth boundary 103' is L3 + a + c. In the third pixel unit 103, when the third pixel unit 103 satisfies L3 < L1 + 2a - c, it means that along the first direction X, there is no overlap between the third sub-pixel 13 and the second sub-pixel 12. Along the second direction Y, the distance between the third sub-pixel 13 and the second sub-pixel 12 is the difference between L3 and (L1 + 2a - c). Since the distance between the first sub-pixel 11 and the sixth boundary 103" is L2 + 3a, and the distance between the edge of the fourth sub-pixel 14 adjacent to the third sub-pixel 13 and the sixth boundary 103" is L4 + a + c. In the third pixel unit 103, when the third pixel unit 103 satisfies L4 < L2 + 2a - c, it means that along the first direction X, there is no overlap between the fourth sub-pixel 14 and the first sub-pixel 11, and along the second direction Y, the distance between the fourth sub-pixel 14 and the first sub-pixel 11 is the difference between L4 and (L2 + 2a - c).

[0046] Optionally, continue to refer to Figure 4 As shown, along the first direction X and the second direction Y, the third pixel units 103 are arranged in rows and columns. Multiple third pixel units 103 are arranged in rows along the first direction X, and multiple third pixel units 103 are arranged in columns along the second direction Y. The fifth boundary 103' of one third pixel unit 103 overlaps with the sixth boundary 103" of the adjacent third pixel unit 103. It can be understood that the pixel units 10 in the organic light-emitting display panel are all composed of the third pixel units 103 arranged in rows and columns, the manufacturing process is simple and it ensures that each sub-pixel has a high space utilization rate. Thus, the aperture utilization rate of the entire pixel unit 10 is improved, ensuring that the organic light-emitting display panel has a high display quality.

[0047] It should be noted that the pixel units 10 in the organic light-emitting display panel can be composed of any combination of one or more of the first pixel unit 101, the second pixel unit 102, and the third pixel unit 103. The embodiments of the present invention do not make specific limitations in this regard. Optionally, in any of the above embodiments, a < b < c, and its specific value can be set according to actual needs. The embodiments of the present invention do not make specific limitations in this regard.

[0048] Optionally, continue to refer to Figures 1 to 4As shown, the length of the first sub-pixel 11 along the second direction Y is L1, the length of the second sub-pixel 12 along the second direction Y is L2, the length of the third sub-pixel 13 along the second direction Y is L3, and the length of the fourth sub-pixel 14 along the second direction Y is L4. (L3+L4)≤(L1+L2).

[0049] It is understandable that when preparing each sub-pixel in the pixel unit 10, evaporation technology is usually used, that is, evaporation film forming technology is used to form a light-emitting layer of corresponding color at the corresponding pixel position on the substrate through a high-precision metal mask (Fine Metal Mask, FMM), and the high-precision metal mask is usually referred to as a mask. The mask includes a shielding area and a plurality of evaporation openings, wherein the evaporation opening corresponds to the predetermined sub-pixel position, and the shielding area is a non-evaporation opening area. If the evaporation opening is large and the shielding area of ​​the mask is small, the strength of the mask is poor, which easily causes the mask to deform or be damaged. Therefore, by setting the lengths of the first sub-pixel 11, the second sub-pixel 12, the third sub-pixel 13 and the fourth sub-pixel 14 in the second direction Y to satisfy (L3+L4)≤(L1+L2), it can be ensured that there is a large distance between the third sub-pixel 13 in the pixel unit 10 and the fourth sub-pixel 14 in the adjacent pixel unit 10, that is, the area of ​​the blocking area of ​​the corresponding mask plate is large, so as to avoid deformation of the mask plate when preparing the pixel unit 10 and improve the yield of the preparation process.

[0050] Optional, Figure 5 A partial structural diagram of a pixel unit provided in an embodiment of the present invention is shown in FIG. Figure 5 As shown, the organic light emitting display panel further includes a pixel driving circuit layer 30. The pixel driving circuit layer 30 is located between the substrate 20 and the sub-pixel. The pixel driving circuit layer 30 includes a gate signal line 31 ( Figure 5 Other structures in the pixel driving circuit layer 30 except the selection signal line 31 are omitted). The selection signal line 31 extends along the first direction X. Along the second direction Y, a first gap area D1 is included between the third sub-pixel 13 and the fourth sub-pixel 14. In a direction perpendicular to the substrate 20, the selection signal line 31 at least partially overlaps with the first gap area D1. Optionally, in a direction perpendicular to the plane where the substrate 20 is located, the first gap area D1 covers the selection signal line 31. It should be noted that the sub-pixel and the pixel circuit can optionally be electrically connected through an electrical connection structure (not shown in the figure) to transmit signals. The electrical connection structure may include a first part in the same layer as the anode of the sub-pixel. Optionally, the first part is integrated with the anode of the sub-pixel to reduce process complexity.

[0051] Among them, the substrate 20 can be a rigid substrate, and its material can be glass. The substrate 20 can also be a flexible substrate, and its material can include one or a combination of polymer resins such as polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, and cellulose acetate propionate. Here, the substrate is not limited.

[0052] Specifically, the pixel driving circuit layer 30 is composed of multiple film layers, including a semiconductor layer, an inorganic insulating layer, a metal layer, an organic insulating layer, etc. According to the specific structure of the pixel driving circuit actually used to drive the pixel unit to work, the specific structure of the pixel driving circuit layer 30 will also be different. The embodiments of the present invention do not make special limitations on the specific structure of the pixel driving circuit layer 30. Exemplarily, taking the pixel driving circuit layer 30 including a conventional 7TIC circuit as an example, the pixel driving circuit layer 30 includes a gate signal line 31 for providing a scan signal or a light emission control signal. For the convenience of understanding and description of the technical solution, Figure 5 only an exemplary structural schematic diagram of the pixel driving circuit layer 30 including the gate signal line 31 is shown. Thus, in the direction perpendicular to the substrate 20, the gate signal line 31 overlaps with the first gap region D1, that is, the first gap region D1 is greater than or equal to the width of the gate signal line 31 in the second direction Y, which can avoid the generation of overlapping capacitance between the third sub-pixel 13 or the fourth sub-pixel 14 and the gate signal line 31, affect the stable transmission of the signal on the gate signal line 31, ensure the display uniformity of the organic light-emitting display panel, and improve the display quality.

[0053] It should be noted that in other embodiments, the arrangement of each sub-pixel in the pixel unit 10 can also be other ways. Without special instructions, the following embodiments will all be Figure 5 exemplarily described with the structure of the arrangement of each sub-pixel in the shown pixel unit 10.

[0054] Optionally, Figure 6 is a partial structural schematic diagram of another organic light-emitting display panel provided by the embodiments of the present invention. As Figure 6 shown, the organic light-emitting display panel further includes a substrate 20 and a pixel driving circuit layer 30. The pixel driving circuit layer 30 is located between the substrate 10 and the sub-pixels. The pixel driving circuit layer 30 includes a data line 32 for providing a data signal ( Figure 6 other structures in the pixel driving circuit layer 30 except the data line 32 are omitted in the figure). The data line 32 extends along the second direction Y. The sub-pixel includes an anode 100. In the direction perpendicular to the substrate 20, the anode 100 overlaps with the data line 32.

[0055] It can be understood that the organic light-emitting display panel generally includes an anode 100 and a cathode arranged opposite to each other ( Figure 6(not shown in the figure), and a light-emitting layer located between the anode 100 and the cathode ( Figure 6 (not shown in the figure). Under the driving of the electric field between the anode 100 and the cathode, the light-emitting layer emits light. With the development of the organic light-emitting display panel towards high PPI (i.e., the number of pixels per inch of the display screen), the larger the pixel aperture ratio, the better. On this basis, the wiring arrangement of the driving circuit layer 30 is also very dense, and there is an inevitable overlap between the signal lines and the structures of other different layers.

[0056] Exemplarily, in the direction perpendicular to the substrate 20, when the sub-pixels in each pixel unit 10 overlap with the data line 32, and the overlapping areas of the sub-pixels of different pixel units 10 with different data lines 32 are different, it will have different effects on the signals transmitted by each data line 32. For example, due to the overlap of the sub-pixels and the data line 32, loads such as impedance or capacitance are generated, thereby affecting the stability of the data signal transmitted by the data line 32 and the light-emitting display uniformity of the light-emitting display panel.

[0057] Based on this, Figure 6 Exemplarily shown in the direction perpendicular to the substrate 20, the anodes 100 corresponding to the third sub-pixel 13 and the fourth sub-pixel 14 in the pixel unit 10 overlap with the same data line 32, and the overlapping situation of each pixel unit 10 with different data lines 32 is the same. In this way, each data line 32 can have the same load situation, which is beneficial to improving the light-emitting display uniformity of the light-emitting display panel.

[0058] In other embodiments, the overlapping areas of the anodes 100 of the sub-pixels in each pixel unit 10 with different data lines 32 are the same or similar, so that each data line 32 has the same or similar load situation, which is beneficial to improving the light-emitting display uniformity of the light-emitting display panel and is also beneficial to the layout of the circuit. Details are not described herein again, and those skilled in the art can make adaptive adjustments according to actual needs. It should be noted that in the known technology, if one data line 32 overlaps with the structure of the first metal layer and another data line 32 overlaps with the structure of the second metal layer, then these two data lines 32 overlap with different metal layers respectively, and the load differences generated on these two data lines 32 are relatively large. In this application, by overlapping each data line 32 with the anodes 100 of the same layer, since each anode 100 is located in the same metal layer, the load differences caused to each data line 32 are relatively small.

[0059] Optionally, continue to refer to Figure 6 As shown, along the second direction Y, a first gap region D1 is included between the third sub-pixel 13 and the fourth sub-pixel 14. In the direction perpendicular to the substrate 20, the data line 32 overlaps with the first gap region D1.

[0060] It can be understood that in an organic light-emitting display panel (exemplarily: medium or large display panel), when a data line 32 has a break, a repair method can be used to repair the break. Among them, generally, the short side dimension of a medium or large organic light-emitting display panel is greater than 10 cm, and the long side dimension is greater than 20 cm. Of course, it is not limited to this data point. Medium or large organic light-emitting display panels can be applied to display devices larger than mobile phone sizes, such as tablets (i.e., pads), computer displays, TV displays, and in-vehicle displays, etc. If there is no gap between the third sub-pixel 13 and the fourth sub-pixel 14, that is, the third sub-pixel 13 and the fourth sub-pixel 14 are an integral whole. When performing welding repair on the data line 32, for example, electrically connecting the two ends of the broken data line 32 using surrounding metal, it may cause the repair path to be too long, thereby affecting the traces or signal line performance in the pixel driving circuit that has no problem, resulting in performance differences between this circuit and other normal circuits (for example, the length, width, resistance, etc. of the signal line are different from those of other normal circuits).

[0061] Figure 7 FIG. is a partial structural schematic diagram of data line repair of an organic light-emitting display panel provided by an embodiment of the present invention. Combining Figure 6 and Figure 7 as shown, by leaving a certain gap, i.e., the first gap region D1, between the third sub-pixel 13 and the fourth sub-pixel 14, and overlapping the data line 32 with the first gap region D1 between the third sub-pixel 13 and the fourth sub-pixel 14 in a direction perpendicular to the substrate 20, the continuous coverage area of the data line 32 in the second direction Y can be reduced, facilitating quick positioning of the break point of the data line 32. Since the first gap region D1 can be used as the repair point of the data line 32, compared with not setting the first gap region D1, the number of repair points of the data line 32 is increased. By introducing other repair wirings to the minimum extent, while enabling the data line 32 to work properly, the differences from other pixel driving circuits or signal lines are reduced. Refer to Figure 7 . When repairing the break point of the data line 32, a nearby signal line can be used, such as a power supply signal line (i.e., PVDD) or a reference signal line (i.e., Vref), etc., and a part of this signal line is intercepted as a repair line 33 and welded to the two ends of the break point of the data line 32 to achieve the repair of the data line 32.

[0062] It should be noted that the power supply signal line (i.e., PVDD) can have a grid-like structure. The power supply signal line includes a horizontal power supply signal line extending along the first direction X and a vertical power supply signal line extending along the second direction Y. As a setting method, the horizontal power supply signal line is on the same layer as the upper electrode plate of the storage capacitor. The horizontal power supply signal line is in the metal layer between the first metal layer and the second metal layer, and can be called the MC metal layer. Among them, the gate of the thin film transistor is located in the first metal layer, and the source and drain of the thin film transistor are located in the second metal layer. The vertical power supply signal line is on the same layer as the data line 32. The vertical power supply signal line is located in the third metal layer. The horizontal power supply signal line and the vertical power supply signal line are on different layers and are electrically connected through vias. Among them, along the direction away from the substrate 20, the first metal layer, the second metal layer, and the third metal layer are arranged in sequence. Since the power supply signal line has a grid-like structure, after a part is cut off, it does not affect its normal use. Then, in an embodiment, a part of the horizontal power supply signal line and a part of the vertical power supply signal line can be cut off, and the cut-off horizontal power supply signal line and vertical power supply signal line are used as the repair line 33. Similarly, the reference signal line can have a grid-like structure, including a horizontal reference signal line and a vertical reference signal line. In an embodiment, a part of the horizontal reference signal line and a part of the vertical reference signal line can be cut off, and the cut-off horizontal reference signal line and vertical reference signal line are used as the repair line 33. In other embodiments, the cut-off horizontal power supply signal line and the vertical reference signal line can also be used as the repair line 33, or the cut-off horizontal reference signal line and the vertical power supply signal line can be used as the repair line 33.

[0063] Optionally, continue to refer to Figure 5 As shown, in the same pixel unit 10, a first gap region D1 is included between the third sub-pixel 13 and the fourth sub-pixel 14, and a second gap region D2 is included between the first sub-pixel 11 and the second sub-pixel 12. Along the first direction X, the first gap region D1 and the second gap region D2 at least partially overlap. The first gap region D1 and the second gap region D2 are oppositely arranged along the first direction X.

[0064] Specifically, the first gap region D1 and the second gap region D2 are set to at least partially overlap. On the one hand, it is convenient for the layout of signal lines. For example, in the direction perpendicular to the substrate 20, the gate signal line for providing a scan signal or a light emission control signal overlaps with the first gap region D1, so that the gate signal line can at least partially overlap with the second gap region D2. In this way, it is avoided that the gate signal line overlaps with all sub-pixels in the pixel unit 10 in the direction perpendicular to the substrate 20 to generate an overlap capacitance, thereby affecting the signal transmission of the gate signal line. On the other hand, due to the existence of the first gap region D1 and the second gap region D2, when actually fabricating the pixel driving circuit layer 30, the vias (not shown in the figure) that electrically connect the circuit for driving the sub-pixels to emit light in the pixel driving circuit layer 30 to the anodes of the sub-pixels are all arranged in the first gap region D1 or the second gap region D2, and each via is on the same straight line parallel to the first direction X, or each via is approximately on the same straight line parallel to the first direction X. In this way, the fabricated pixel driving circuit layout is relatively regular, which is beneficial to simplifying the fabrication process. It should be noted that each via is on the same straight line, or each via is approximately on a straight line, and the pixel driving circuits in each pixel driving circuit layer 30 can be arranged in the original manner without changing the positions of the pixel driving circuits in the pixel driving circuit layer 30, that is, they can be adapted to each sub-pixel in this application.

[0065] Optionally, Figure 8 is a schematic partial structure diagram of another pixel unit provided by an embodiment of the present invention. As Figure 8 shown, the sub-pixel includes an anode 100. The organic light-emitting display panel further includes an anode connection portion 110, and the anode connection portion 110 is on the same layer as the anode 100. Along the first direction X, the width of the anode connection portion 110 is smaller than the width of the anode 100. The anode connection portion 110 connects the anode 100 of the third sub-pixel 13 and the anode 100 of the fourth sub-pixel 14 in the same pixel unit 10.

[0066] Specifically, when the third sub-pixel 13 and the fourth sub-pixel 14 share the same pixel driving circuit, the anode 100 of the third sub-pixel 13 and the anode 100 of the fourth sub-pixel 14 can be the same anode 100.

[0067] Exemplarily, Figure 9 is Figure 8 a schematic cross-sectional structure diagram along the A-A' direction. As Figure 8 and Figure 9As shown, the anode 100 of the third sub-pixel 13 is connected to the anode 100 of the fourth sub-pixel 14 through the anode connection portion 110. The anode connection portion 110 is disposed on the same layer as the anode 100. In this way, there is no need to add a metal layer to connect the anode 100 of the third sub-pixel 13 and the anode 100 of the fourth sub-pixel 14. It is beneficial to the thin and light design of the light-emitting display panel. In the same process, the same material can be used to form the anode 100 of the third sub-pixel 13, the anode 100 of the fourth sub-pixel 14, and the anode connection portion 110 at the same time, which simplifies the manufacturing process.

[0068] Exemplarily, referring to Figure 9 , the sub-pixel includes an anode 100, a light-emitting layer, and a cathode ( Figure 9 not shown in

[0069] In another alternative embodiment, Figure 10 is a partial structural schematic diagram of another pixel unit provided by an embodiment of the present invention, Figure 11 is Figure 10 a cross-sectional structural schematic diagram along the B-B' direction. Referring to Figure 10 and Figure 11 shown, the sub-pixel includes an anode 100. The organic light-emitting display panel further includes a substrate 20 and a pixel driving circuit layer 30. The pixel driving circuit layer 30 is located between the substrate 20 and the anode 100. The pixel driving circuit layer 30 includes a connection wire 34. The connection wire 34 connects the anode 100 of the third sub-pixel 13 and the anode 100 of the fourth sub-pixel 14 in the same pixel unit 10.

[0070] Exemplarily, the pixel driving circuit layer 30 further includes a thin film transistor, and the thin film transistor is located between the connection wire 34 and the substrate 20.

[0071] Specifically, when the third sub-pixel 13 and the fourth sub-pixel 14 share the same pixel driving circuit, the anode 100 of the third sub-pixel 13 and the anode 100 of the fourth sub-pixel 14 can be separated by a pixel defining layer 40. The anode 100 of the third sub-pixel 13 is electrically connected to the connection wire 34 through a via. Similarly, the anode 100 of the fourth sub-pixel 14 is also electrically connected to the connection wire 34 through a via. The connection wire 34 is electrically connected to the source or drain of the driving transistor (not shown in the figure) in the pixel driving circuit layer 30 to realize the light-emitting display of the third sub-pixel 13 and the fourth sub-pixel 14 driven by the same pixel driving circuit. It should be noted that the position of the connection wire 34 in the pixel driving circuit layer 30 is not limited in the embodiment of the present invention, Figure 11 only an exemplary cross-sectional structural schematic diagram of the third sub-pixel 13 and the fourth sub-pixel 14 in the pixel unit 10 is shown.

[0072] Optionally, continue to refer to Figure 10 and Figure 11As shown, in the same pixel unit 10, the pixel opening 351 of the third sub-pixel 13 and the pixel opening 352 of the fourth sub-pixel 14 have the same area.

[0073] Those skilled in the art can understand that for the third sub-pixel 13 and the fourth sub-pixel 14 with the same luminous intensity, the larger the corresponding pixel opening, the greater the luminous flux of the light emitted from the corresponding display area. The smaller the corresponding pixel opening, the smaller the luminous flux of the light emitted from the corresponding display area. Thus, by setting the pixel opening 351 of the third sub-pixel 13 and the pixel opening 352 of the fourth sub-pixel 14 to have the same area, it can ensure that the third sub-pixel 13 and the fourth sub-pixel 14 have the same light-emitting effect, thereby improving the light-emitting display uniformity of the light-emitting display panel.

[0074] Based on any of the above embodiments, optionally, Figure 12 It is a schematic partial cross-sectional structure diagram of an organic light-emitting display panel provided by an embodiment of the present invention, which can be combined with Figure 4 and Figure 12 As shown, the organic light-emitting display panel includes a substrate 20, a pixel defining layer 40, and support pillars 50. The pixel defining layer 40 is provided with a plurality of openings 41, and sub-pixels are located in the openings 41. The support pillars 50 are located on the side of the pixel defining layer 40 away from the substrate 20. Along the second direction Y, the support pillars 50 are located between the third sub-pixel 13 and the fourth sub-pixel 14 of two adjacent pixel units 10, and the distance between the third sub-pixel 13 and the fourth sub-pixel 14 of two adjacent pixel units 10 is (2a + 2c).

[0075] It can be understood that during the preparation process of the display panel, the support pillars 50 can play a role in supporting the evaporation mask. After evaporation, the display panel is encapsulated to isolate water and oxygen. The support pillars 50 can be made of organic materials or inorganic materials. For example, polyimide (PI) or polyethylene terephthalate (PET) can be used, etc. The embodiments of the present invention do not make specific limitations on this.

[0076] Specifically, by arranging the support pillars 50 between the third sub-pixel 13 and the fourth sub-pixel 14 of two adjacent pixel units 10, and the distance between the third sub-pixel 13 and the fourth sub-pixel 14 of two adjacent pixel units 10 is 2a + 2c. By arranging the support pillars 50 at the position where the distance between two sub-pixels is the largest along the second direction Y, it can ensure that the area of the vertical projection of the support pillars 50 on the substrate 20 is large enough, thereby facilitating increasing the height and support strength of the support pillars 50 and improving the reliability of the light-emitting display panel.

[0077] It should be noted that generally, the area of the opening 41 provided in the pixel defining layer 40 is smaller than the area of the anode 100. The area of the opening 41 provided in the pixel defining layer 40 defines the light-emitting area of the sub-pixel. Thus, the opening 41 provided in the pixel defining layer 40 is the pixel opening (including the pixel opening 351 of the third sub-pixel 13 and the pixel opening 352 of the fourth sub-pixel 14).

[0078] Based on the same inventive concept, an embodiment of the present invention further provides a display device, Figure 13 which is a schematic structural diagram of a display device provided by an embodiment of the present invention. As Figure 13 shown, the display device 90 includes the organic light-emitting display panel 91 of any embodiment of the present invention. Therefore, the display device 90 provided by the embodiment of the present invention has the technical effects of the technical solutions in any of the above embodiments. The same or corresponding structures and explanations of terms as those in the above embodiments will not be elaborated herein. The display device 90 provided by the embodiment of the present invention may be Figure 13 the mobile phone shown in the figure, or any electronic product with a display function, including but not limited to the following categories: television sets, laptop computers, desktop monitors, tablet computers, digital cameras, smart bracelets, smart glasses, in-vehicle displays, medical devices, industrial control devices, touch interaction terminals, etc. The embodiment of the present invention does not make special limitations thereto.

[0079] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
