Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a display panel and a display device. Background Art

[0002] OLED (Organic Light-Emitting Diode) display devices are widely used due to advantages such as self-luminescence, wide color gamut, low power consumption, and the ability to achieve flexible display. In order to display images of different colors, current OLED display devices respectively set red sub-pixels, green sub-pixels, and blue sub-pixels, and achieve pure color display or color display by separately displaying the red sub-pixels, green sub-pixels, and blue sub-pixels, or by mixing light of two or three of the red sub-pixels, green sub-pixels, and blue sub-pixels. Specifically, in some OLED display devices, sub-pixels of the same emission color are set in the same column, and sub-pixels of different emission colors are set in the same row, so that sub-pixels of different emission colors in the same row form a pixel, thereby realizing the normal display of the OLED display device. However, in the actual use process, it is found that when any one sub-pixel fails, the corresponding pixel cannot work, resulting in abnormal display during display.

[0003] Therefore, the current OLED display device has the technical problem that abnormal display will occur when any one sub-pixel fails. Summary of the Invention

[0015] According to a second aspect of the present application, a display device is provided, and the display device includes a display panel as described in any one of the above embodiments.

[0016] An embodiment of the present application provides a display panel and a display device. The display panel includes a plurality of repeating units arranged in an array.

[0017] Other features and advantages of the present application will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following drawings are only some embodiments of the present application. For those skilled in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0024] To illustrate the principle of the technical problem in the embodiments of the present application, a comparative display device is provided. It can be understood that this comparative display device cannot be regarded as the prior art of the embodiments of the present application. As Figure 1 shown, the comparative display device includes a red sub-pixel 111, a green sub-pixel 112, and a blue sub-pixel 113. Sub-pixels of the same color are arranged in the same column, and sub-pixels of different emission colors are arranged in the same row. From Figure 1 it can be seen that the red sub-pixels 111 form a column, the green sub-pixels 112 form a column, and the blue sub-pixels 113 form a column. The red sub-pixels 111, the green sub-pixels 112, and the blue sub-pixels 113 are located in the same row. The adjacent red sub-pixels 111, green sub-pixels 112, and blue sub-pixels 113 in the same row form a light-emitting pixel 11. From Figure 1 it can be seen that since each light-emitting pixel 11 has only one sub-pixel of each emission color, when one sub-pixel fails, the light-emitting pixel 11 will fail, resulting in abnormal display of the comparative display device. Therefore, the current OLED display device has the technical problem that any sub-pixel failure will cause abnormal display.

[0025] The embodiments of the present application provide a display panel and a display device to solve the above technical problems.

[0026] As Figures 2 to 3 shown, the embodiments of the present application provide a display panel. The display panel 2 includes a plurality of repeating units 21 arranged in an array. Each repeating unit 21 includes two first sub-pixel units 211, one second sub-pixel unit 212, and one third sub-pixel unit 213. The first sub-pixel unit 211, the second sub-pixel unit 212, and the third sub-pixel unit 213 have different emission colors;

[0027] Wherein, within one of the repeating units 21, one of the first sub-pixel units 211 and the second sub-pixel unit 212 are in the same row, another one of the first sub-pixel units 211 and the second sub-pixel unit 212 are in the same column, and another one of the first sub-pixel units 211 and the third sub-pixel unit 213 are in the same row. The area of the first sub-pixel unit 211 is smaller than the area of the second sub-pixel unit 212, and the area of the second sub-pixel unit 212 is smaller than the area of the third sub-pixel unit 213.

[0028] An embodiment of the present application provides a display panel. By making one repeating unit 21 include two first sub-pixel units 211, one second sub-pixel unit 212, and one third sub-pixel unit 213, and within one repeating unit 21, one first sub-pixel unit 211 and the second sub-pixel unit 212 are in the same row, another first sub-pixel unit 211 and the second sub-pixel unit 212 are in the same column, and another first sub-pixel unit 211 and the third sub-pixel unit 213 are in the same row. The area of the first sub-pixel unit 211 is smaller than the area of the second sub-pixel unit 212, and the area of the second sub-pixel unit 212 is smaller than the area of the third sub-pixel unit 213. Then, the sub-pixel units can be mixed with each other in a crosswise manner up and down. When some sub-pixel units fail, other sub-pixel units can be used for display, thereby improving the yield rate of the display panel. When the display panel is displaying, different combinations of sub-pixel units can be used for display, thereby improving the pixel utilization rate and color gamut of the display panel, and the luminous efficiency and lifespan of different sub-pixels can be made similar or even the same, improving the display effect.

[0029] Specifically, as Figure 2 shown, the display panel 2 includes a display area 201 and a non-display area 202. The non-display area 202 can be arranged to surround the display area 201, but the embodiment of the present application is not limited thereto. The non-display area 202 can be arranged on one side, both sides, or three sides of the display area 201, and the non-display area 202 can be bent to the back of the display area 201. Taking Figure 2 as an example, the non-display area 202 can include a left border area, a right border area, a lower border area, and an upper border area. A gate driving circuit can be arranged in the left border area and the right border area, and binding terminals can be arranged in the lower border area and bound to a driving chip.

[0030] Specifically, for the widths of the respective borders in the non-display area, the width of the lower border area can be made relatively large, so as to have sufficient space for setting the fan-out routing and bonding terminals, and for bonding the driving chip and / or the flexible circuit board. Moreover, the lower border area can be bent to; for the left border area and the right border area, they can be set to be relatively large, so that there is a relatively large space for setting the gate driving circuit, and a relatively large space for setting the transistors and routing in the gate driving circuit, avoiding problems such as broken wires and short circuits, and enabling the display panel to work properly.

[0031] Specifically, as Figure 2 shown, the display panel 2 includes multiple rows of sub-pixel units and multiple columns of sub-pixel units arranged in an array. Figure 2 Taking the first row of sub-pixel units as the second sub-pixel unit 212 and the first sub-pixel unit 211 arranged alternately, and the second row of sub-pixel units as the first sub-pixel unit 211 and the third sub-pixel unit 213 arranged alternately as an example for illustration. However, the embodiments of the present application are not limited thereto. It is possible that the first row of sub-pixel units is the first sub-pixel unit 211 and the third sub-pixel unit 213 arranged alternately, and the second row of sub-pixel units is the second sub-pixel unit 212 and the first sub-pixel unit 211 arranged alternately.

[0032] Specifically, as Figure 2 shown, the display panel 2 includes multiple rows of sub-pixel units and multiple columns of sub-pixel units arranged in an array. Figure 2 Taking the first column of sub-pixel units as the second sub-pixel unit 212 and the first sub-pixel unit 211 arranged alternately, and the second column of sub-pixel units as the first sub-pixel unit 211 and the third sub-pixel unit 213 arranged alternately as an example for illustration. However, the embodiments of the present application are not limited thereto. It is possible that the first column of sub-pixel units is the first sub-pixel unit 211 and the third sub-pixel unit 213 arranged alternately, and the second column of sub-pixel units is the second sub-pixel unit 212 and the first sub-pixel unit 211 arranged alternately.

[0033] Specifically, the display panel includes pixel units, the pixel units include sub-pixel units, and the sub-pixel units include a first sub-pixel unit 211, a second sub-pixel unit 212, and a third sub-pixel unit 213.

[0034] Specifically, compared with the comparative display device, one light-emitting pixel 11 is composed of a red sub-pixel 111, a green sub-pixel 112, and a blue sub-pixel 113 in the same row. The failure of one sub-pixel will cause the failure of the light-emitting pixel 11, resulting in display abnormalities in the display panel. It can only be repaired or scrapped. The repair process is relatively complex, resulting in low efficiency. Direct scrapping will reduce the yield of the display panel and increase the cost. From Figure 2As can be seen, in the embodiments of the present application, sub-pixel units of different emission colors are staggered. When a sub-pixel unit fails, pixel units can be formed by other sub-pixel units, thereby avoiding display abnormalities caused by sub-pixel failures and improving the yield of the display panel. For example, in a repeating unit, if a first sub-pixel unit 211 fails, another first sub-pixel unit 211 can still display normally, enabling the pixel unit to work properly and improving the yield of the display panel.

[0035] Specifically, compared with the contrast display device, a light-emitting pixel 11 can only be displayed through a red sub-pixel 111, a green sub-pixel 112, and a blue sub-pixel 113 in the same row, resulting in a smaller color gamut. In the embodiments of the present application, the first sub-pixel unit 211, the second sub-pixel unit 212, and the third sub-pixel unit 213 are staggered, and can be displayed through different numbers of sub-pixel units, thereby improving the color gamut. For example, in a repeating unit, there are two first sub-pixel units 211, one second sub-pixel unit 212, and one third sub-pixel unit 213. Then, one first sub-pixel unit 211, one second sub-pixel unit 212, and one third sub-pixel unit 213 can form a pixel unit, or two first sub-pixel units 211, one second sub-pixel unit 212, and one third sub-pixel unit 213 can form a pixel unit, and the sub-pixel units between different repeating units can be borrowed from each other, thereby improving the color gamut.

[0036] Specifically, compared with the contrast display device, a light-emitting pixel 11 is composed of a red sub-pixel 111, a green sub-pixel 112, and a blue sub-pixel 113 in the same row, resulting in a low pixel utilization rate. In the embodiments of the present application, by staggering the sub-pixel units of different emission colors, each pixel unit can borrow the same sub-pixel unit, thereby improving the pixel utilization rate. For example, a third sub-pixel unit 213 can be used as the sub-pixel unit in two pixel units, thereby improving the pixel utilization rate.

[0037] In some embodiments, such as Figure 2 、 Figure 3As shown, the length of one side of the first sub-pixel unit 211 is greater than the length of the adjacent side (for example, the length L1 of the long side 211a of the first sub-pixel unit 211 is greater than the length L2 of the short side 211b of the first sub-pixel unit 211), and the extension directions of the same side of the first sub-pixel units 211 in adjacent rows are different (for example, the long side 211a of the first sub-pixel unit 211 in one row of the first sub-pixel units in adjacent rows extends in the first direction, and the short side 211b of the first sub-pixel unit 211 in the other row extends in the second direction). By making the length of one side of the first sub-pixel unit 211 greater than the length of the adjacent side and the extension directions of the same side of the first sub-pixel units 211 in adjacent rows different, one of the two first sub-pixel units 211 can extend horizontally and the other can extend vertically. Then, when the areas of the second sub-pixel unit 212 and the third sub-pixel unit 213 are different, the arrangement mode of the first sub-pixel unit can be set according to the areas of the second sub-pixel unit 212 and the third sub-pixel unit 213. Through the cooperation of the first sub-pixel unit 211, the second sub-pixel unit 212, and the third sub-pixel unit 213, the occupied area of the repeating unit is reduced, and the pixel density of the display panel is improved.

[0038] Specifically, when setting the second sub-pixel unit 212 and the third sub-pixel unit 213, one of the second sub-pixel unit 212 and the third sub-pixel unit 213 can have a larger area and the other can have a relatively smaller area. When the second sub-pixel unit 212 and the third sub-pixel unit 213 are arranged on the diagonal line, it can be understood that one of the side lengths of the second sub-pixel unit 212 and the third sub-pixel unit is relatively large. Then, the side of the first sub-pixel unit 211 with a larger length can be correspondingly arranged with the side of one of the second sub-pixel unit 212 and the third sub-pixel unit with a larger side length, and the side of the first sub-pixel unit 211 with a smaller length can be correspondingly arranged with the side of one of the second sub-pixel unit 212 and the third sub-pixel unit with a smaller side length, thereby reducing the occupied area of the repeating unit and improving the pixel density of the display panel. However, the embodiments of the present application are not limited thereto. When the length of the side of the first sub-pixel unit 211 with a larger length is less than or equal to the length of the side of one of the second sub-pixel unit 212 and the third sub-pixel unit with a smaller side length, the side of the first sub-pixel unit 211 with a larger length can also be correspondingly arranged with the side of one of the second sub-pixel unit 212 and the third sub-pixel unit with a smaller side length.

[0039] In some embodiments, such as Figure 2 、 Figure 3As shown, the shape of the first sub-pixel unit 211 includes a rectangle. The long sides 211a of the first sub-pixel units 211 in one of two adjacent rows are arranged along the first direction X, and the long sides 211a of the first sub-pixel units 211 in the other row of the two adjacent rows are arranged along the second direction Y. The included angle between the first direction X and the second direction Y is greater than 0 and less than or equal to 90 degrees. By making the shape of the first sub-pixel unit 211 include a rectangle, the long sides 211a of the first sub-pixel units 211 in one row are arranged along the first direction X, and the long sides 211a of the first sub-pixel units 211 in the other row are arranged along the second direction Y, such that one row of the first sub-pixel units 211 occupies the space in the first direction X and reduces the space occupied in the second direction Y, and the other row of the first sub-pixel units 211 occupies the space in the second direction Y and reduces the space occupied in the first direction X. The first sub-pixel unit 211 determines its extension direction according to the side lengths of the second sub-pixel unit 212 and the third sub-pixel unit 213, so that the area occupied by the repeating unit formed by each sub-pixel unit is relatively small, and the pixel density of the display panel is improved.

[0040] Specifically, if the first sub-pixel unit 211 is a rectangle, then the length of one side of the first sub-pixel unit 211 is relatively large, and the length of the other side is relatively small. Then, the long side of the first sub-pixel unit 211 can be correspondingly arranged with the side with a relatively large side length among the second sub-pixel unit 212 and the third sub-pixel unit 213, and the short side of the first sub-pixel unit 211 can be correspondingly arranged with the side with a relatively small side length among the second sub-pixel unit 212 and the third sub-pixel unit, thereby reducing the occupied area of the repeating unit and improving the pixel density of the display panel. However, the embodiments of the present application are not limited thereto. When the length of the long side of the first sub-pixel unit 211 is less than or equal to the length of the side with a relatively small side length among the second sub-pixel unit 212 and the third sub-pixel unit 213, the long side of the first sub-pixel unit 211 can be correspondingly arranged with the side with a relatively small side length among the second sub-pixel unit 212 and the third sub-pixel unit 213.

[0041] In some embodiments, such as Figure 2As shown, the short side 211b of the first sub-pixel unit 211 is disposed opposite to the side 212a of the second sub-pixel unit 212, and the long side 211a of the first sub-pixel unit 211 is disposed opposite to the side 213a of the third sub-pixel unit 213. By disposing the short side 211b of the first sub-pixel unit 211 opposite to the side of the second sub-pixel unit 212 and the long side 211a of the first sub-pixel unit 211 opposite to the side of the third sub-pixel unit 213, when the side of the third sub-pixel unit 213 is relatively large, the space occupied by the long side 211a of the first sub-pixel unit 211 is the space occupied by the side of the third sub-pixel unit 213, avoiding the first sub-pixel unit 211 occupying more space, reducing the space occupied by the repeating unit, and improving the pixel density of the display panel.

[0042] In some embodiments, as Figure 2 shown, the shape of the second sub-pixel unit 212 includes a square, the shape of the third sub-pixel unit 213 includes a square, the length L2 of the short side 211b of the first sub-pixel unit 211 is less than the side length L3 of the second sub-pixel unit 212, and the length L1 of the long side 211a of the first sub-pixel unit 211 is equal to the side length L4 of the third sub-pixel unit 213. By making the shape of the second sub-pixel unit 212 a square, the shape of the third sub-pixel unit 213 a square, the length L2 of the short side 211b of the first sub-pixel unit 211 less than the side length L3 of the second sub-pixel unit 212, and the length L1 of the long side 211a of the first sub-pixel unit 211 equal to the side length L4 of the third sub-pixel unit 213, it is possible to make the extending direction of the long side 211a of the first sub-pixel unit 211 the same as the extending direction of the side of the third sub-pixel unit 213, so that the horizontal and vertical occupied spaces of the first sub-pixel unit 211 are opposite to the horizontal and vertical occupied spaces of the third sub-pixel unit 213, avoiding the first sub-pixel unit 211 occupying extra space, reducing the space occupied by the repeating unit, and improving the pixel density of the display panel.

[0043] Specifically, as Figure 2 shown, it can be seen that the long side 211a of the first sub-pixel unit 211 is correspondingly disposed with the side of the third sub-pixel unit 213. Since the side of the third sub-pixel unit 213 necessarily occupies the space corresponding to its side length, disposing the long side 211a of the first sub-pixel unit 211 correspondingly with the side of the third sub-pixel unit 213 enables the first sub-pixel unit 211 not to occupy extra space. Compared with the long side of the first sub-pixel unit 211 having the same arrangement direction, the space occupied by the repeating unit can be reduced, and the pixel density of the display panel can be improved.

[0044] In some embodiments, as Figure 2As shown, in the first direction X, the pitch K1 between the first sub-pixel unit 211 and the second sub-pixel unit 212 is less than the pitch K2 between the first sub-pixel unit 211 and the third sub-pixel unit 213. In the second direction Y, the pitch K3 between the first sub-pixel unit 211 and the second sub-pixel unit 212 is less than the pitch K4 between the first sub-pixel unit 211 and the third sub-pixel unit 213.

[0045] In some embodiments, as Figure 3 shown, the short side 211b of the first sub-pixel unit 211 is disposed opposite to the side 213a of the third sub-pixel unit 213, and the long side 211a of the first sub-pixel unit 211 is disposed opposite to the side 212a of the second sub-pixel unit 212. By disposing the short side 211b of the first sub-pixel unit 211 opposite to the side 213a of the third sub-pixel unit 213 and the long side 211a of the first sub-pixel unit 211 opposite to the side 212a of the second sub-pixel unit 212, when the side of the second sub-pixel unit 212 is relatively small and the length of the long side of the first sub-pixel unit 211 is not greater than the side of the second sub-pixel unit 212, the space occupied by the long side 211a of the first sub-pixel unit 211 is the same as the space occupied by the side of the second sub-pixel unit 212, avoiding the first sub-pixel unit 211 occupying more space, reducing the space occupied by the repeating unit, and increasing the pixel density of the display panel.

[0046] In some embodiments, as Figure 3 shown, the shape of the second sub-pixel unit 212 includes a square, the shape of the third sub-pixel unit 213 includes a square, the length L1 of the long side 211a of the first sub-pixel unit 211 is equal to the side length L3 of the second sub-pixel unit 212, and the length L2 of the short side 211b of the first sub-pixel unit 211 is less than the side length L4 of the third sub-pixel unit 213. By making the shape of the second sub-pixel unit 212 a square, the shape of the third sub-pixel unit 213 a square, the length L1 of the long side 211a of the first sub-pixel unit 211 equal to the side length L3 of the second sub-pixel unit 212, and the length L2 of the short side 211b of the first sub-pixel unit 211 less than the side length L4 of the third sub-pixel unit 213, the extending direction of the long side 211a of the first sub-pixel unit 211 can be made the same as the extending direction of the side of the second sub-pixel unit 212, so that the horizontal and vertical occupied spaces of the first sub-pixel unit 211 are opposite to the horizontal and vertical occupied spaces of the second sub-pixel unit 212, avoiding the first sub-pixel unit 211 occupying extra space, reducing the space occupied by the repeating unit, and increasing the pixel density of the display panel.

[0047] Specifically, as Figure 3As shown, it can be seen that the long side 211a of the first sub-pixel unit 211 is correspondingly arranged with the side of the second sub-pixel unit 212. Since the side of the second sub-pixel unit 212 necessarily occupies the space corresponding to its side length, arranging the long side 211a of the first sub-pixel unit 211 corresponding to the side of the second sub-pixel unit 212 enables the first sub-pixel unit 211 not to occupy extra space, which can reduce the space occupied by the repeating unit and improve the pixel density of the display panel.

[0048] In some embodiments, in the first direction X, the distance K1 between the first sub-pixel unit 211 and the second sub-pixel unit 212 is greater than the distance K2 between the first sub-pixel unit 211 and the third sub-pixel unit 213. In the second direction Y, the distance K3 between the first sub-pixel unit 211 and the second sub-pixel unit 212 is greater than the distance K4 between the first sub-pixel unit 211 and the third sub-pixel unit 213.

[0049] In some embodiments, as Figure 2 , Figure 3 shown, the area of the first sub-pixel unit 211 is smaller than the area of the second sub-pixel unit 212, and the area of the second sub-pixel unit 212 is smaller than the area of the third sub-pixel unit 213. By making the area of the first sub-pixel unit smaller than that of the second sub-pixel unit and the area of the second sub-pixel unit smaller than that of the third sub-pixel unit, the area can be set according to the lifetimes and luminous efficiencies of different light-emitting materials, so that the lifetimes and luminous efficiencies of the sub-pixel units are similar or even the same.

[0050] Specifically, when the shape of the first sub-pixel unit is rectangular, the shape of the second sub-pixel unit is square, and the shape of the third sub-pixel unit is square, the side length of the third sub-pixel unit can be made greater than the side length of the second sub-pixel unit; the side length of the second sub-pixel unit can be made equal to the length of the long side of the first sub-pixel unit, and the side length of the second sub-pixel unit is greater than the length of the short side of the first sub-pixel unit, or the side length of the second sub-pixel unit is smaller than the length of the long side of the first sub-pixel unit, and the side length of the second sub-pixel unit is greater than the length of the short side of the first sub-pixel unit.

[0051] Specifically, within a repeating unit 21, the area of one sub-pixel unit can be made greater than the area of one second sub-pixel unit, and the area of one second sub-pixel unit can be made greater than the area of one third sub-pixel unit; or the area of one sub-pixel unit can be made greater than the area of one second sub-pixel unit, and the area of one second sub-pixel unit can be made greater than the sum of the areas of two third sub-pixel units.

[0052] In some embodiments, the light-emitting color of the first sub-pixel unit 211 is red, the light-emitting color of the second sub-pixel unit 212 is green, and the light-emitting color of the third sub-pixel unit 213 is blue. By making the light-emitting colors of the first sub-pixel unit 211, the second sub-pixel unit 212, and the third sub-pixel unit 213 be red, green, and blue respectively, and the area of the first sub-pixel unit 211 is smaller than the area of the second sub-pixel unit 212, and the area of the second sub-pixel unit 212 is smaller than the area of the third sub-pixel unit 213, the light-emitting efficiencies and lifetimes of the respective sub-pixel units are made to be similar or even the same.

[0053] Specifically, for example, the lengths of the long side and the short side of the first sub-pixel unit can be 6 micrometers and 3 micrometers respectively, the side length of the second sub-pixel unit can be 5 micrometers, the side length of the third sub-pixel unit can be 6 micrometers, the spacing between the first sub-pixel unit and the second sub-pixel unit can be 4 micrometers, and the spacing between the first sub-pixel unit and the third sub-pixel unit can be 5 micrometers. It is also possible to make the lengths of the long side and the short side of the first sub-pixel unit be 6 micrometers and 2 micrometers respectively, the side length of the second sub-pixel unit can be 5 micrometers, the side length of the third sub-pixel unit can be 6 micrometers, the spacing between the first sub-pixel unit and the second sub-pixel unit can be 4 micrometers, and the spacing between the first sub-pixel unit and the third sub-pixel unit can be 6 micrometers.

[0054] Specifically, the above embodiments have described the display panel in detail from aspects such as the pixel arrangement of the display panel, the colors of the respective sub-pixel units, the areas of the respective sub-pixel units, and the relative positional relationship between the respective sub-pixel units. It can be understood that when there is no conflict among the embodiments, the embodiments can be combined. For example, the short side of the first sub-pixel unit is arranged opposite to the side of the second sub-pixel unit, the long side of the first sub-pixel unit is arranged opposite to the side of the third sub-pixel unit, the light-emitting color of the first sub-pixel unit is red, the light-emitting color of the second sub-pixel unit is green, and the light-emitting color of the third sub-pixel unit is blue.
