Description

Technical Field

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

[0002] Organic light-emitting diode (OLED) display panels have been widely used in many fields such as flat panel display, flexible display, car display and solid-state lighting due to their advantages such as wide color gamut, high contrast, energy saving and foldability. With the development of display technology, under-screen sensor solutions (under-screen optical device solutions) such as under-screen camera solutions and under-screen fingerprint recognition solutions have also become one of the solutions for full-screen displays. For example, the under-screen camera solution (CUP technology) is to set the camera under the display panel. When used, the camera receives light passing through the display panel for imaging. In order to improve the imaging effect of the under-screen camera, it is necessary to ensure that the display area corresponding to the camera has a large transmittance.

[0003] However, the under-screen sensor solution in the prior art has the problem that it is difficult to optimize both the display effect and the transmittance at the same time. Summary of the invention

[0004] Based on this, it is necessary to provide a display panel and a display device, aiming to solve the problem in the prior art that it is difficult to simultaneously optimize the display effect and transmittance of the under-screen sensor solution.

[0019] In some embodiments, at least the first color sub-pixel group and the third color sub-pixel group each include at least 2 sub-pixels;

[0020] Different sub-pixels in the same sub-pixel group are formed by using the same evaporation opening on the evaporation mask.

[0037] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or there may be intervening elements. Further, when a layer is referred to as being "under" another layer, it can be directly under or there may be one or more intervening elements. It is also understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there may be one or more intervening elements.

[0040] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0041] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present application.

[0042] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0043] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0044] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0045] As mentioned in the background technology section, the existing under-screen sensor solution has the problem that it is difficult to optimize both the display effect and the transmittance at the same time. The inventors found that the reason for the above phenomenon is that the transmittance of the optical device area needs to be increased to improve the imaging quality. However, increasing the light transmittance of the optical device area will lead to a decrease in the display effect of the optical device area.

[0046] Based on the above technical problems, the inventors have found that by optimizing the pixel arrangement in the optical device area, the light transmittance in the optical device area can be ensured while optimizing the display quality in the optical device area. The inventors have found that a plurality of large pixel groups arranged at intervals are arranged in the optical device area (second display area), and the large pixel group includes four sub-pixel groups, and the four sub-pixel groups include a first color sub-pixel group, two second color sub-pixel groups, and one third color sub-pixel group; in the large pixel group, the first color sub-pixel group and the third color sub-pixel group are adjacently arranged along the first direction, and the two second color sub-pixel groups are arranged along the second direction and are located on both sides of the line between the center of the first color sub-pixel group and the center of the third color sub-pixel group, and the first direction intersects with the second direction. In the embodiment of the present application, the sub-pixel group is centrally arranged in the large pixel group, and the area between the adjacent two large pixel groups is a light-transmitting area. On the first hand, in some embodiments, it is possible to avoid the first electrodes (such as anodes) of multiple light-emitting devices being arranged in the entire area of ​​the second display area, so that the first electrodes of multiple light-emitting devices between the adjacent two large pixel groups are removed; on the second hand, in some embodiments, it is convenient to centrally arrange the second electrodes (such as cathodes) of multiple light-emitting devices in the large pixel group, so that the second electrodes of multiple light-emitting devices between the adjacent two large pixel groups are removed. Based on one or both of these aspects, the light transmittance of the second display area can be improved, thereby improving the imaging quality of the optical device. In an embodiment of the present application, on the first aspect, a large pixel group includes four sub-pixel groups, and the four sub-pixel groups include a first color sub-pixel group, two second color sub-pixel groups and a third color sub-pixel group. The number of second color sub-pixel groups is twice that of the first color sub-pixel groups, and the number of second color sub-pixel groups is twice that of the third color sub-pixel groups, which can reduce the use of the second color sub-pixel groups, thereby improving the resolution of the second display area and the display effect; on the second aspect, in the large pixel group, the first color sub-pixel group and the third color sub-pixel group are adjacently arranged along the first direction, and the two second color sub-pixel groups are arranged along the second direction and are located on both sides of the line between the center of the first color sub-pixel group and the center of the third color sub-pixel group, so that in one large pixel group, the first color sub-pixel group, the two second color sub-pixel groups and the third color sub-pixel group are evenly distributed, avoiding excessive concentration of sub-pixel groups of a certain color, thereby improving display uniformity and improving display quality.

[0047] See also Figures 1 to 8. Figure 1 A schematic top view of a display panel provided in an embodiment of the present application.

[0048] The present application provides a display panel 100, which includes a display area AA, wherein the display area AA includes a first display area AA1 and a second display area AA2, and the second display area AA2 is multiplexed as an optical device area; the display panel 100 includes a plurality of large pixel groups P10, and the plurality of large pixel groups P10 are arranged at intervals in the second display area AA2; wherein the large pixel group P10 includes four sub-pixel groups 10, and the four sub-pixel groups 10 include a first color sub-pixel group P01, two second color sub-pixel groups P02, and one third color sub-pixel group P03; in the large pixel group P10, the first color sub-pixel group P01 and the third color sub-pixel group P03 are adjacently arranged along a first direction Y, and the two second color sub-pixel groups P02 are arranged along a second direction X, and are located on both sides of a line between the center of the first color sub-pixel group P01 and the center of the third color sub-pixel group P03, and the first direction Y intersects with the second direction X.

[0049] For example, the display panel 100 may include a display area AA and a non-display area BB surrounding the display area AA, the display area AA may include a first display area AA1 and a second display area AA2, the second display area AA2 is an area corresponding to optical devices such as a camera or a fingerprint sensor, the first display area AA1 is a normal display area, and the transmittance of the second display area AA2 is greater than the transmittance of the first display area AA1, so that more light reaches optical devices such as cameras.

[0050] For example, an optical device such as a camera or a fingerprint sensor is disposed on a side of the second display area AA2 away from the light emitting side, and the second display area AA2 can also display an image.

[0051] For example, in some embodiments, a transition display area may be further provided between the first display area AA1 and the second display area AA2, the transmittance of the second display area AA2 is greater than that of the transition display area, and the transmittance of the transition display area is greater than that of the first display area AA1.

[0052] It should be noted that the second display area AA2 may be a region corresponding to a camera sensor, the second display area AA2 may be a region corresponding to a fingerprint recognition sensor, or the second display area AA2 may be a region corresponding to a camera sensor.

[0053] For example, Figure 2 As shown, in the second display area AA2, the display panel 100 includes a plurality of large pixel groups P10 arranged at intervals, the sub-pixel group 10 is centrally arranged in the large pixel group P10, and the area between the two adjacent large pixel groups P10 is a light-transmitting area TA1, and light can pass through the light-transmitting area TA1 to reach the optical device, and / or, light emitted by the optical device can pass through the light-transmitting area TA1 to reach the light-emitting side of the second display area AA2.

[0054] For example, one or more light-emitting devices in the first color sub-pixel group P01 emit light of a first color. One or more light-emitting devices in the second color sub-pixel group P02 emit light of a second color. One or more light-emitting devices in the third color sub-pixel group P03 emit light of a third color.

[0055] For example, Figure 3 As shown, the two second color sub-pixel groups P02 are arranged along the second direction X, the line between the center of the first color sub-pixel group P01 and the center of the third color sub-pixel group P03 is the first line C1-C1, and the two second color sub-pixel groups P02 are arranged along the second direction X and are located on both sides of the first line C1-C1, so that in one large pixel group P10, one first color sub-pixel group P01, two second color sub-pixel groups P02 and one third color sub-pixel group P03 are evenly distributed.

[0056] By way of example, the first direction Y and the second direction X may be perpendicular to each other, but are not limited thereto.

[0057] In the embodiment of the present application, the sub-pixel group 10 is centrally arranged in the large pixel group P10, and the area between the two adjacent pixel groups P10 is the light-transmitting area TA1. On the one hand, in some embodiments, it is possible to avoid the first electrodes (such as anodes) of multiple light-emitting devices being arranged in the entire area of ​​the second display area AA2, so that the first electrodes of multiple light-emitting devices between the two adjacent pixel groups P10 are removed; on the other hand, in some embodiments, it is convenient to centrally arrange the second electrodes (such as cathodes) of multiple light-emitting devices in the large pixel group P10, so that the second electrodes of multiple light-emitting devices between the two adjacent pixel groups P10 are removed. Based on one or both of these aspects, the light transmittance of the second display area AA2 can be improved, thereby improving the imaging quality of the optical device.

[0058] In the embodiment of the present application, on the first aspect, the large pixel group P10 includes four sub-pixel groups 10, and the four sub-pixel groups 10 include a first color sub-pixel group P01, two second color sub-pixel groups P02 and a third color sub-pixel group P03. The number of the second color sub-pixel groups P02 is twice that of the first color sub-pixel group P01, and the number of the second color sub-pixel groups P02 is twice that of the third color sub-pixel group P03, which can reduce the use of the second color sub-pixel group P02, thereby improving the resolution of the second display area AA2 and improving the display effect; on the second aspect, in In the large pixel group P10, the first color sub-pixel group P01 and the third color sub-pixel group P03 are adjacently arranged along the first direction Y, and the two second color sub-pixel groups P02 are arranged along the second direction X and are located on both sides of the line between the center of the first color sub-pixel group P01 and the center of the third color sub-pixel group P03, so that in one large pixel group P10, the first color sub-pixel group P01, the two second color sub-pixel groups P02 and the one third color sub-pixel group P03 are evenly distributed, avoiding excessive concentration of a certain color sub-pixel group, thereby improving display uniformity and display quality.

[0059] In some embodiments, Figure 2 As shown, at least one large pixel group P10 is disposed adjacent to six large pixel groups P10 , the six large pixel groups P10 disposed adjacent to one large pixel group P10 are arranged in a hexagon, and one large pixel group P10 disposed adjacent to the six large pixel groups P10 is located at the center of the hexagon 101 .

[0060] For example, Figure 2As shown, it is illustrated that multiple pixel groups P10 include a first large pixel group P11, a second large pixel group P12, a third large pixel group P13, a fourth large pixel group P14, a fifth large pixel group P15, a sixth large pixel group P16 and a seventh large pixel group P17. The first large pixel group P11 is adjacent to the second large pixel group P12, the third large pixel group P13, the fourth large pixel group P14, the fifth large pixel group P15, the sixth large pixel group P16 and the seventh large pixel group P17. The second large pixel group P12, the third large pixel group P13, the fourth large pixel group P14, the fifth large pixel group P15, the sixth large pixel group P16 and the seventh large pixel group P17 are arranged in a hexagon 101. The first large pixel group P11 is located at the center of the hexagon 101, so that the arrangement uniformity of the multiple large pixel groups P10 in the second display area AA2 can be improved, thereby improving the display quality of the second display area AA2.

[0061] For example, six large pixel groups P10 adjacent to a large pixel group P10 are arranged in a hexagonal shape. In the first direction Y, adjacent large pixel groups P10 are staggered, so that the distribution of multiple spaced large pixel groups P10 is more uniform, the display effect of the second display area AA2 is better, and the sawtooth phenomenon such as oblique lines can be optimized. The distribution of the evaporation openings on the precision metal mask plate (FMM) is also more uniform, which is beneficial to the improvement of the flatness and mechanical strength of the precision metal mask plate.

[0062] In some embodiments, Figure 2 As shown, the first direction Y is perpendicular to the sides of the hexagon.

[0063] In some embodiments, Figure 2 As shown, the hexagon is an equilateral hexagon.

[0064] In some embodiments, Figure 2 As shown, the first direction Y is perpendicular to the second direction X.

[0065] For example, when at least one of the following conditions is met, the arrangement uniformity of the plurality of large pixel groups P10 in the second display area AA2 can be improved, thereby improving the display quality of the second display area AA2: the first direction Y is perpendicular to the side of the hexagon; the hexagon is an equilateral hexagon; the first direction Y is perpendicular to the second direction X.

[0066] For example, Figure 2 As shown, the hexagon is an equilateral hexagon, and the angle between the line connecting the adjacent large pixel group P10 located at the corner of the hexagon and the large pixel group P10 located at the center of the hexagon is 60 degrees ( Figure 2 The first angle α is 60 degrees), the large pixel group P10 is distributed more evenly in the second display area AA2, so that the second display area AA2 has a better display effect for oblique lines, arcs, etc. at different angles.

[0067] In some embodiments, Figure 3 As shown, in the same large pixel group P10, the first color sub-pixel group P01 includes a first side P01a adjacent to the third color sub-pixel group P03, the third color sub-pixel group P03 includes a second side P03a adjacent to the first color sub-pixel group P01, and the first side P01a is adjacent to the second side P03a.

[0068] For example, in some embodiments, the first side P01a and the second side P03a do not actually exist, and at least one light-emitting device in the first color sub-pixel group P01 is disposed adjacent to at least one light-emitting device in the third color sub-pixel group P03.

[0069] By way of example, in some embodiments, the first side P01a is the side of at least one light-emitting device in the first color sub-pixel group P01, the second side P03a is the side of at least one light-emitting device in the third color sub-pixel group P03, and at least one light-emitting device in the first color sub-pixel group P01 is arranged adjacent to at least one light-emitting device in the third color sub-pixel group P03.

[0070] For example, Figure 3 By way of example, the display panel 100 may include three display situations: in a first display situation, the first color sub-pixel group P01, the third color sub-pixel group P03 and the second color sub-pixel group P02 on the left are displayed; in a second display situation, the first color sub-pixel group P01, the third color sub-pixel group P03 and the second color sub-pixel group P02 on the right are displayed; in a third display situation, the first color sub-pixel group P01, the third color sub-pixel group P03, the second color sub-pixel group P02 on the left and the second color sub-pixel group P02 on the right are displayed. The first side P01a and the second side P03a are arranged adjacent to each other, and the two second color sub-pixel groups P02 are arranged along the second direction X and are located on both sides of the line between the center of the first color sub-pixel group P01 and the center of the third color sub-pixel group P03. It can be found that in the above three display situations, the overlapping area of ​​the positions of the multiple sub-pixel groups participating in the display is the largest, which avoids the large area displacement of the sub-pixel groups participating in the display in different display situations. It is not easy for the human eye to observe defects such as flickering or picture displacement, thereby improving the display quality.

[0071] In some embodiments, Figure 3 As shown, in the same large pixel group P10, the line between the center of the first color sub-pixel group P01 and the center of the third color sub-pixel group P03 is perpendicular to the line between the centers of the two third color sub-pixel groups P03.

[0072] For example, Figure 3As shown, the line between the center of the first color sub-pixel group P01 and the center of the third color sub-pixel group P03 is the first line C1-C1, and the line between the centers of the two third color sub-pixel groups P03 is the second line C2-C2. The first line C1-C1 is perpendicular to the second line C2-C2. When the second display area AA2 displays images of arcs, oblique lines, etc. of Chinese characters, the edges of these images are made more neat and smooth, and adjacent and continuous large pixel groups P10 can be involved in displaying images of arcs, oblique lines, etc. of Chinese characters. There is no need to separate one or more large pixel groups P10 from participating in the display, which improves the continuity and resolution rate of the second display area AA2 displaying images of arcs, oblique lines, etc. of Chinese characters, thereby improving the display quality.

[0073] In some embodiments, Figure 3 As shown, in the same large pixel group P10, a second color sub-pixel group P02 and another second color sub-pixel group P02 are arranged in line symmetry or center symmetry.

[0074] For example, Figure 3 As an example, the display panel 100 includes two display situations: in the first display situation, the first color sub-pixel group P01, the third color sub-pixel group P03 and the left second color sub-pixel group P02 are displayed; in the second display situation, the first color sub-pixel group P01, the third color sub-pixel group P03 and the right second color sub-pixel group P02 are displayed. In the same large pixel group P10, a second color sub-pixel group P02 and another second color sub-pixel group P02 are arranged in line symmetry or center symmetry, so that in the same large pixel group P10, the second color sub-pixel group P02 participating in the above two display situations has the same area, similar or symmetrical graphics, and improves the display quality.

[0075] In some embodiments, Figure 3 As shown, the first color sub-pixel group P01 includes at least one first color sub-pixel 11, the second color sub-pixel group P02 includes at least one second color sub-pixel 21, and the third color sub-pixel group P03 includes at least one third color sub-pixel 31; in the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is 1:1:1 or 1:2:1.

[0076] For example, the first color sub-pixel group P01 includes one or more first color sub-pixels, the second color sub-pixel group P02 includes one or more second color sub-pixels, and the third color sub-pixel group P03 includes one or more third color sub-pixels, but in the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is maintained at 1:1:1 or 1:2:1.

[0077] For example, Figure 3 It is illustrated that the first color sub-pixel group P01 includes 2 first color sub-pixels (or two first color light-emitting devices), the second color sub-pixel group P02 includes 2 second color sub-pixels (or two second color light-emitting devices), and the third color sub-pixel group P03 includes 2 third color sub-pixels (or two third color light-emitting devices). In the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is 1:2:1.

[0078] For example, Figure 4 It is illustrated that the first color sub-pixel group P01 includes 3 first color sub-pixels (or three first color light-emitting devices), the second color sub-pixel group P02 includes 3 second color sub-pixels (or three second color light-emitting devices), and the third color sub-pixel group P03 includes 3 third color sub-pixels (or three third color light-emitting devices). In the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is 1:2:1.

[0079] For example, Figure 5 It is illustrated that the first color sub-pixel group P01 includes 4 first color sub-pixels, the second color sub-pixel group P02 includes 2 second color sub-pixels, and the third color sub-pixel group P03 includes 4 third color sub-pixels. In the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is 1:1:1.

[0080] For example, Figure 6 It is illustrated that the first color sub-pixel group P01 includes 6 first color sub-pixels, the second color sub-pixel group P02 includes 3 second color sub-pixels, and the third color sub-pixel group P03 includes 6 third color sub-pixels. In the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is 1:1:1.

[0081] For example, Figure 7 It is illustrated that the first color sub-pixel group P01 includes 6 first color sub-pixels, the second color sub-pixel group P02 includes 3 second color sub-pixels, and the third color sub-pixel group P03 includes 6 third color sub-pixels. In the same large pixel group P10, the ratio of the number of first color sub-pixels 11, second color sub-pixels 21 and third color sub-pixels 31 is 1:1:1.

[0082] For example, in some embodiments, in the same large pixel group P10, the ratio of the number of the first color sub-pixel 11, the second color sub-pixel 21 and the third color sub-pixel 31 is maintained at 1:2:1, so that the number of pixels in the large pixel group P10 can be increased, the resolution can be improved, and the sub-pixels of multiple colors in different pixels can be distributed as evenly as possible in the large pixel group P10. Figure 3 For example, a large pixel group P10 includes two pixels, each pixel includes a first color sub-pixel 11, a second color sub-pixel 21 in the second color sub-pixel group P02 on the left, a second color sub-pixel 21 in the second color sub-pixel group P02 on the right, and a third color sub-pixel 31.

[0083] For example, in some embodiments, in the same large pixel group P10, the number ratio of the first color sub-pixel 11, the second color sub-pixel 21, and the third color sub-pixel 31 is maintained at 1:1:1, so that the sub-pixels of multiple colors in different pixels are distributed as evenly as possible in the large pixel group P10. Figure 5 For example, a large pixel group P10 includes four pixels, wherein each of the two pixels includes a first color sub-pixel 11, a second color sub-pixel 21 in the second color sub-pixel group P02 on the left, and a third color sub-pixel 31, and each of the other two pixels includes a first color sub-pixel 11, a second color sub-pixel 21 in the second color sub-pixel group P02 on the right, and a third color sub-pixel 31.

[0084] In some embodiments, Figure 3 As shown, at least the first color sub-pixel group P01 and the third color sub-pixel group P03 include at least two sub-pixels respectively; different sub-pixels in the same sub-pixel group 10 are formed using the same evaporation opening on the evaporation mask.

[0085] For example, different sub-pixels in the same sub-pixel group 10 are formed using the same evaporation opening on the evaporation mask. When the light-emitting material of the light-emitting device is evaporated through a precision metal mask (FMM mask), different sub-pixels in the same sub-pixel group 10 can be formed by using the light-emitting material evaporated from the same evaporation opening on the precision metal mask, thereby reducing the number and density of the evaporation openings in the precision metal mask, thereby facilitating the manufacture of the precision metal mask, reducing the cost of the precision metal mask, and improving the flatness and other properties of the precision metal mask in the evaporation process.

[0086] In some embodiments, Figure 3As shown, the first color sub-pixel group P01 is one of the red sub-pixel group and the blue sub-pixel group, the third color sub-pixel group P03 is the other of the red sub-pixel group and the blue sub-pixel group, and the second color sub-pixel group P02 is the green sub-pixel group.

[0087] For example, human eyes are sensitive to green light, and the second color sub-pixel group P02 is a green sub-pixel group. Providing a larger number of green sub-pixel groups 10 can improve the comfort of human eyes when viewing the second display area AA2.

[0088] For example, two green sub-pixel groups are set in the large pixel group P10, so that the green sub-pixel groups are more evenly distributed in the second display area AA2, which can make the picture more delicate and avoid false resolution caused by the sharing of green sub-pixel groups (the green sub-pixel groups do not need to be shared in different pixels), while the sharing of red sub-pixel groups and blue sub-pixel groups in different pixels can increase the area of ​​the light-transmitting area TA1, thereby ensuring the transmittance of the second display area AA2.

[0089] For example, two green sub-pixel groups are arranged in the large pixel group P10. By adding a green sub-pixel group, the resolution of the second display area AA2 can be doubled, thereby further optimizing the display effect.
