Description

Technical Field

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

[0002] Currently, users have privacy protection requirements for display products in some usage scenarios, such as when using electronic products in public places, or in large-screen car displays to prevent the passenger from interfering with the driver's screen. Although privacy films can meet users' privacy protection needs, only users facing the screen can clearly see the content on the screen after applying the film, which also limits the use environment of the display product after the film is applied. In recent years, active privacy protection technology that can flexibly switch between privacy protection and non-privacy protection has also made certain progress. To implement active privacy protection technology, the pixels in the panel need to be segmented, which will inevitably affect the pixel pitch and service life. Therefore, how to layout the sub-pixels in the panel has become a research focus in active privacy protection technology. Summary of the Invention

[0003] Embodiments of the present invention provide a display panel, a display device, and a vehicle, so as to provide a sub-pixel layout solution to meet the requirements of active anti-peeping technology.

[0004] In a first aspect, an embodiment of the present invention provides a display panel, comprising a plurality of pixels, each pixel comprising a first sub-pixel and at least two second sub-pixels of the same color, wherein the at least two second sub-pixels are located on both sides of the first sub-pixel.

[0005] In a second aspect, based on the same inventive concept, an embodiment of the present invention further provides a display device, comprising the display panel provided by any embodiment of the present invention.

[0006] On the third aspect, based on the same inventive concept, an embodiment of the present invention further provides a vehicle, comprising the display device provided by any embodiment of the present invention.

[0007] The display panel, display device and vehicle provided by the embodiments of the present invention have the following beneficial effects: the pixels are set to include a first sub-pixel and a second sub-pixel of the same color, and the second sub-pixel is arranged on both sides of the first sub-pixel, that is, the second sub-pixel is arranged around the first sub-pixel, and the first sub-pixel is roughly located in the center area of ​​the pixel where it is located. In this way, the arrangement rule of the first sub-pixels of different colors in the display panel can be the same as the arrangement rule of the pixels of different colors, and the first sub-pixels of different colors cooperate to display white dots. In addition, the second sub-pixel is located on the periphery of the first sub-pixel, and the spacing between the second sub-pixels of different colors of adjacent pixels of different colors will also be relatively small, and the effect of the second sub-pixels of different colors cooperating to display white dots will also be better. In the application, the first sub-pixel can be used as an anti-peeping sub-pixel and the second sub-pixel can be used as a non-anti-peeping sub-pixel. The light emission of the first sub-pixel and the second sub-pixel can be controlled according to the usage scenario to achieve switching between anti-peeping mode and non-anti-peeping mode, meeting the needs of active anti-peeping technology.

DETAILED DESCRIPTION

[0010] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0011] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a," "an," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0012] Figure 1 A partial schematic diagram of a display panel provided by an embodiment of the present invention. Figure 1 Schematic diagram of an arrangement of multiple pixels in the display area. Figure 1As shown, the display panel includes multiple pixels P. Each pixel P includes a first subpixel sp1 and at least two second subpixels sp2 of the same color. Within each pixel P, the at least two second subpixels sp2 are located on either side of the first subpixel sp1. It will be appreciated that to display a color image, the pixel P includes a first pixel P1, a second pixel P2, and a third pixel P3 of different colors. The first pixel P1, the second pixel P2, and the third pixel P3 are each a red pixel, a green pixel, or a blue pixel. Each of the three color pixels P includes a first subpixel sp1 and a second subpixel sp2 of the corresponding color.

[0013] In a display panel provided by an embodiment of the present invention, a pixel P includes a first subpixel sp1 and a second subpixel sp2 of the same color. The second subpixel sp2 is arranged on either side of the first subpixel sp1, that is, arranged around the first subpixel sp1, with the first subpixel sp1 approximately located in the center of the pixel P in which it resides. This ensures that the arrangement of the different-colored first subpixels sp1 in the display panel is consistent with the arrangement of the different-colored pixels P, effectively displaying a white dot with the different-colored first subpixels sp1. Furthermore, the second subpixel sp2's location around the first subpixel sp1 reduces the spacing between the different-colored second subpixels sp2 of adjacent different-colored pixels P, further improving the display effect of the different-colored second subpixels sp2. In applications, the first subpixel sp1 can be used as an anti-peeping subpixel, while the second subpixel sp2 can be used as a non-anti-peeping subpixel. The illumination of the first and second subpixels sp1 and sp2 can be controlled based on the usage scenario to switch between anti-peeping and non-anti-peeping modes, thus meeting the requirements of active anti-peeping technology.

[0014] The display panel provided by an embodiment of the present invention includes a first mode and a second mode. In the first mode, the first subpixel sp1 emits light, while the second subpixel sp2 does not. In the second mode, the first subpixel sp1 does not emit light, the second subpixel sp2 emits light, or both the first subpixel sp1 and the second subpixel sp2 emit light. The first mode is an anti-peeping mode, and the second mode is a non-anti-peeping mode. Switching between the different modes is achieved by controlling the light emission of the first subpixel sp1 and the second subpixel sp2, meeting the requirements of active anti-peeping technology.

[0015] The display panel provided by the embodiment of the present invention includes a pixel circuit, and the pixel circuit can be any one in the prior art. Figure 2 A schematic diagram of another display panel provided by an embodiment of the present invention. Figure 2 The connection between each sub-pixel and the pixel circuit at the position of a pixel P is only simplified. Figure 2As shown, the pixel circuit 30 includes a first pixel circuit 31 and a second pixel circuit 32 ; the first sub-pixel sp1 is electrically connected to the first pixel circuit 31 , and the second sub-pixel sp2 is electrically connected to the second pixel circuit 32 . Figure 2 The figure shows the signal output terminal W of the pixel circuit 30, and the sub-pixel is electrically connected to the signal output terminal W. In this embodiment of the present invention, pixel circuits 30 are provided for the first sub-pixel sp1 and the second sub-pixel sp2, respectively. This allows for independent control of the first sub-pixel sp1 and the second sub-pixel sp2, meeting the display requirements of different operating modes of the display panel. For example, only one of the first sub-pixel sp1 and the second sub-pixel sp2 can be controlled to emit light at the same time, or both can be controlled to emit light at the same time.

[0016] like Figure 2 As shown, the second sub-pixel sp2 belonging to one pixel P is electrically connected to the same second pixel circuit 32. Such an arrangement can reduce the number of second pixel circuits 32 arranged in the display panel and save wiring space of the display panel.

[0017] In other embodiments, Figure 3 A schematic diagram of another display panel provided by an embodiment of the present invention. Figure 3 The connection between each sub-pixel and the pixel circuit at the position of a pixel P is only simplified. Figure 3 As shown, the pixel circuit 30 includes a first pixel circuit 31 and a second pixel circuit 32; the first subpixel sp1 is electrically connected to the first pixel circuit 31, and each second subpixel sp2 in the pixel P is electrically connected to the second pixel circuit 32 in a one-to-one correspondence. This arrangement allows different second subpixels sp2 in a pixel P to be controlled independently of each other. For example, in some modes, one second subpixel sp2 in the pixel P can be controlled to emit light while another second subpixel sp2 is not, or the second subpixels sp2 can be controlled to emit light at different brightnesses, thereby meeting more display requirements.

[0018] In some embodiments, as Figure 1 As shown, the second sub-pixels sp2 located on both sides of the first sub-pixel sp1 in the pixel P are symmetrical with respect to the first sub-pixel sp1. This arrangement can promote the regularity of the arrangement of the second sub-pixels sp2 of different colors in the display area. It can be used with a sub-pixel rendering algorithm to drive multiple second sub-pixels sp2 of different colors to display images, making the positions of each pixel in the image uniform and improving the overall image display effect.

[0019] In some embodiments, as Figure 1The illustrated pixel P includes two second sub-pixels sp2, one on either side of the first sub-pixel sp1. This allows for a relatively large size of a single second sub-pixel sp2 within the layout space of the pixel P, i.e., a larger opening area for the second sub-pixel sp2, which helps extend the lifespan of the second sub-pixel sp2.

[0020] In other embodiments, Figure 4 Another pixel schematic diagram provided by an embodiment of the present invention. Figure 4 Schematic diagram of the arrangement of the first sub-pixel sp1 and the second sub-pixel sp2 in a pixel P. Figure 4 As shown, the pixel P includes a first sub-pixel sp1 and four second sub-pixels sp2. Two second sub-pixels sp2 are respectively arranged on both sides of the first sub-pixel sp1, and the second sub-pixels sp2 on both sides of the first sub-pixel sp1 are symmetrical with respect to the first sub-pixel sp1.

[0021] In some embodiments of the present invention, the number of the second sub-pixels sp2 in the pixel P may also be 6, and three second sub-pixels sp2 are respectively arranged on both sides of the first sub-pixel sp1, which is not illustrated in the figure here.

[0022] In the embodiment of the present invention, the pixel P may also include an odd number of second sub-pixels sp2. For example, the pixel P includes three second sub-pixels sp2, where one second sub-pixel sp2 is disposed on one side of the first sub-pixel sp1 and two second sub-pixels sp2 are disposed on the other side. The second sub-pixels sp2 located on both sides of the first sub-pixel sp1 have substantially the same total area. That is, the area of ​​one of the three second sub-pixels sp2 is substantially equal to the sum of the areas of the other two second sub-pixels sp2.

[0023] In some embodiments, as Figure 1 As shown, the first sub-pixel sp1 is circular in shape. In the embodiment of the present invention, the first sub-pixel sp1 can be used as an anti-peeping pixel. A corresponding anti-peeping structure needs to be provided on the light-emitting side of the first sub-pixel sp1. Setting the shape of the first sub-pixel sp1 to be circular makes it easier for the anti-peeping structure to cooperate with the first sub-pixel sp1, making the anti-peeping structure easier to design and manufacture, and achieving a better anti-peeping effect.

[0024] A display panel provided by an embodiment of the present invention includes a pixel definition layer having an opening; each sub-pixel includes a stacked first electrode, a light-emitting layer, and a second electrode. At least a portion of the sub-pixel is located within the opening. The opening in the pixel definition layer exposes the first electrode, and the light-emitting layer is located within the opening and extends outside the opening. The opening in the pixel definition layer defines the actual light-emitting area of ​​the sub-pixel. The shape of the sub-pixel is the same as the shape of the opening in which it is located, and the light-emitting area of ​​the sub-pixel is the same as the area of ​​the opening in which the sub-pixel is located.

[0025] In other embodiments, the shape of the first sub-pixel sp1 may be elliptical or polygonal.

[0026] Figure 5 Another pixel schematic diagram provided by an embodiment of the present invention. Figure 5 As shown, a second sub-pixel sp2 is provided on both sides of the first sub-pixel sp1 in the pixel P. The first sub-pixel sp1 is in the shape of a quadrilateral, and the second sub-pixel sp2 is also in the shape of a quadrilateral. While satisfying the arrangement of the first sub-pixel sp1 and the second sub-pixel sp2 in the pixel P in the embodiment of the present invention, the shapes of the first sub-pixel sp1 and the second sub-pixel sp2 can be designed in accordance with actual display requirements.

[0027] In some embodiments, as Figure 1 As shown, in the pixel P, at least the side of the second sub-pixel sp2 away from the first sub-pixel sp1 is arc-shaped. This arrangement makes the outer boundary of the second sub-pixel sp2 arranged around the first sub-pixel sp1 close to a circle, and the second sub-pixels sp2 of different colors cooperate with each other to synthesize a white point with better effect.

[0028] Figure 1 The shape of the first sub-pixel sp1 is circular. Optionally, the side of the second sub-pixel sp2 in the pixel P that is away from the first sub-pixel sp1 and the side of the second sub-pixel sp2 that is close to the first sub-pixel sp1 are both arc-shaped. Around the first sub-pixel sp1, the side of the second sub-pixel sp2 that is close to the first sub-pixel sp1 is designed to match the shape of the first sub-pixel sp1. This also takes into account the coordination of the light emission of the second sub-pixels sp2 between pixels P of different colors. This can maximize the size of the second sub-pixel sp2 and achieve a better effect of synthesizing a white point by cooperating with the second sub-pixels sp2 of different colors.

[0029] In other embodiments, Figure 6 Another pixel schematic diagram provided by an embodiment of the present invention. Figure 6 As shown, in the pixel P, two second sub-pixels sp2 are located on either side of the first sub-pixel sp1. The first sub-pixel sp1 is circular, and the second sub-pixel sp2 is rectangular. In this embodiment, the second sub-pixels sp2 are rectangular, which can increase the area of ​​the second sub-pixels sp2 within a limited space, thereby improving the service life of the second sub-pixels sp2.

[0030] In the first mode of the embodiment of the present invention, only the first sub-pixel sp1 emits light. If the area of ​​the first sub-pixel sp1 is small, then to meet the brightness requirement, the driving current needs to be increased. However, the increased driving current increases power consumption and also reduces the service life of the sub-pixel. Therefore, it is necessary to provide a design that balances the areas of the two sub-pixels.

[0031] In some embodiments of the present invention, the area of ​​the first sub-pixel sp1 is S1, the area of ​​the second sub-pixel sp2 is S2, and S1>S2. The number of first sub-pixels sp1 in a pixel P is less than the number of second sub-pixels sp2, and the area of ​​a single first sub-pixel sp1 in the pixel P is set to be larger than the area of ​​a single second sub-pixel sp2. This can balance the areas of the two sub-pixels, thereby balancing power consumption in different modes, and can also ensure that the service life of both sub-pixels is relatively long.

[0032] In some embodiments, S1≤2 S2. If the area of ​​the first subpixel sp1 is set to no more than twice the area of ​​the second subpixel sp2, the difference between the area of ​​a single first subpixel sp1 and a single second subpixel sp2 in the same pixel P will not be too significant. The difference in the area of ​​the luminous region within the pixel P when the first subpixel sp1 is illuminated alone and the second subpixel sp2 is illuminated alone will not be too significant. The overall brightness difference between displaying with the first subpixel sp1 alone and displaying with the second subpixel sp2 alone is small. Therefore, the power consumption in the two display modes is comparable, and the lifespan of the two subpixels is not significantly different.

[0033] Optionally, when the pixel P includes two second sub-pixels sp2, set S1≤2 S2, the area of ​​the first sub-pixel sp1 in the pixel P is not greater than the sum of the areas of the second sub-pixels sp2.

[0034] In some other embodiments, in a pixel P, the area of ​​the first sub-pixel sp1 is S1, the sum of the areas of the second sub-pixels sp2 is S0, and S1≤S0≤2 S1. This embodiment sets the total area of ​​the second sub-pixels sp2 to be no less than the area of ​​the first sub-pixels sp1, and the total area of ​​the second sub-pixels sp2 to be no more than twice the area of ​​the first sub-pixels sp1. When S1=S0, the area of ​​the luminous region in the pixel P is the same when the first sub-pixel sp1 is lit alone and the second sub-pixel sp2 is lit alone. The overall brightness difference is small when the first sub-pixel sp1 is lit alone for display and the second sub-pixel sp2 is lit alone for display. Therefore, the power consumption in the two display modes is equivalent, and the lifespan of the two sub-pixels is not much different. When S1 <S0≤2 S1: When the second sub-pixel sp2 is illuminated alone, the luminous area within the pixel P is relatively large, which makes it suitable for products where the second sub-pixel sp2 is illuminated more frequently. Properly increasing the total area of ​​the second sub-pixel sp2 can extend the service life of the second sub-pixel sp2 to a certain extent. Furthermore, the total area of ​​the second sub-pixel sp2 is not too large, while also taking into account the service life of the first sub-pixel sp1.

[0035] In some embodiments, Figure 7 for Figure 1 A schematic diagram of a cross section at the midline AA'. Figure 7 As shown, the display panel includes a substrate 00, a driving layer 01 located on one side of the substrate 00, and a pixel definition layer 02 located on a side of the driving layer 01 away from the substrate 00. The pixel definition layer 02 has an opening ( Figure 7 (not shown), the sub-pixel is at least partially located in the opening. The driving layer 01 is provided with a pixel circuit ( Figure 7 (not shown), the pixel circuit is used to drive the sub-pixels connected thereto to emit light. Figure 7 It can be seen that the first sub-pixel sp1 and the second sub-pixel sp2 respectively include a stacked first electrode 11, a light-emitting layer 12, and a second electrode 13. The opening of the pixel definition layer 02 exposes the first electrode 11, and the pixel circuit is electrically connected to the first electrode 11. In the pixel P, the light-emitting layer 12 of the first sub-pixel sp1 and the light-emitting layer 12 of the second sub-pixel sp2 are interconnected as a whole. When the display panel is manufactured, the first sub-pixel sp1 and the second sub-pixel sp2 belonging to a pixel P can share the mask opening in the evaporation process, which can reduce the cost of the evaporation process, and can also reduce the spacing between pixels P of different colors and improve the aperture ratio of the display panel. Figure 1 The dotted box around the illustrated pixel P is the shape of the mask opening. This arrangement allows the spacing between the first sub-pixel sp1 and the second sub-pixel sp2 in a pixel P to be set relatively small, thereby ensuring a high pixel density of the entire display panel.

[0036] In some embodiments, Figure 8 A partial schematic diagram of another display panel provided by an embodiment of the present invention. Figure 8 As shown, the pixels P include a first pixel P1, a second pixel P2, and a third pixel P3 of different colors. Optionally, the first pixel P1 is a green pixel, and one of the second pixel P2 and the third pixel P3 is a red pixel and the other is a blue pixel.

[0037] The centers of the four first sub-pixels sp1 of the four first pixels P1 constitute a first virtual quadrilateral 21, the centers of the two first sub-pixels sp1 of the two second pixels P2 and the centers of the two first sub-pixels sp1 of the two third pixels P3 constitute a second virtual quadrilateral 22. The two first sub-pixels sp1 of the two second pixels P2 are located at opposite corners of the second virtual quadrilateral 22, and the two first sub-pixels sp1 of the two third pixels P3 are located at opposite corners of the second virtual quadrilateral 22. The center of the first sub-pixel sp1 is the geometric center of the pattern of the opening in the pixel definition layer where the first sub-pixel sp1 is located. Figure 8 Taking the shape of the first sub-pixel sp1 as a circle for illustration, the opening of the pixel definition layer where it is located is a circle, and the center of the circle is the center of the first sub-pixel sp1.

[0038] Depend on Figure 8 It can be seen that there is a second pixel P2 or a third pixel P3 in the first virtual quadrilateral 21, and a first pixel P1 in the second virtual quadrilateral 22. The first virtual quadrilateral 21 is a parallelogram, a rectangle, or a trapezoid, and the second virtual quadrilateral 22 is a parallelogram, a rectangle, or a trapezoid.

[0039] The arrangement of the multiple pixels P in the display panel can also be described as follows: multiple first pixels P1 are arranged in a first pixel column in a first direction y, the second pixels P2 and the third pixels P3 are alternately arranged in the first direction y to form a second pixel column, the first pixel column and the second pixel column are alternately arranged in a second direction x, and the pixels in adjacent first pixel columns and second pixel columns are staggered in the second direction x. Multiple first pixels P1 are arranged in a first pixel row in the second direction x, the second pixels P2 and the third pixels P3 are alternately arranged in the second direction x to form a second pixel row, the first pixel row and the second pixel row are alternately arranged in the first direction y, and the pixels in adjacent first pixel rows and second pixel rows are staggered in the first direction y.

[0040] like Figure 8As shown, in the second virtual quadrilateral 22, the first subpixel sp1 of the first pixel P1 is adjacent to the second subpixel sp2 of the second pixel P2, and the second subpixel sp2 of the first pixel P1 is adjacent to the first subpixel sp1 of the third pixel P3; alternatively, the first subpixel sp1 of the first pixel P1 is adjacent to the second subpixel sp2 of the third pixel P3, and the second subpixel sp2 of the first pixel P1 is adjacent to the first subpixel sp1 of the second pixel P2. This arrangement ensures that the second subpixels sp2 of two adjacent pixels P of different colors are not directly opposite each other in the adjacent direction of the two pixels P. In other words, only one second subpixel sp2 of the pixel P is disposed between the center lines connecting the two first subpixels sp1 of the two adjacent pixels P of different colors. Combined with the design of the second subpixels sp2 of the pixels P located on both sides of the first subpixel sp1 in the embodiment of the present invention, the second subpixels sp2 of different colors can be arranged in a regular pattern, and the spacing between pixels P of different colors can be reduced, making the pixels P of different colors more densely arranged and improving the aperture ratio.

[0041] like Figure 8 As shown, in the first pixel P1, the second subpixels sp2 located on both sides of the first subpixel sp1 are symmetrical about the first virtual line X1; in the second pixel P2, the second subpixels sp2 located on both sides of the first subpixel sp1 are symmetrical about the second virtual line X2; in the third pixel P3, the second subpixels sp2 located on both sides of the first subpixel sp1 are symmetrical about the third virtual line X3; wherein, the second virtual line X1 and the third virtual line X3 are parallel, the second virtual line X2 is perpendicular to the first virtual line X1, and the third virtual line X3 is also perpendicular to the first virtual line X1. This arrangement can coordinate with the arrangement of the first subpixels sp1 to make the arrangement of the second subpixels sp2 of different colors more regular, and can also make the arrangement of pixels P of different colors more compact, reduce the distance between pixels P of different colors, improve the aperture ratio, and improve the display effect of the synthetic white point of the subpixels of different colors.

[0042] In some embodiments, both the first virtual quadrilateral 21 and the second virtual quadrilateral 22 are squares, and the side lengths of the first virtual quadrilateral 21 and the second virtual quadrilateral 22 are approximately equal. Such a setting can make the distance between the first sub-pixel sp1 of the first pixel P1 and the first sub-pixels sp1 of the other two colors adjacent to it equal. When the first sub-pixel sp1 is lit for display, the synthesis of white dots in the display area is more uniform, and the display effect is better. Further setting, in the first pixel P1, the second sub-pixels sp2 located on both sides of the first sub-pixel sp1 are symmetric about the first virtual line X1; in the second pixel P2, the second sub-pixels sp2 located on both sides of the first sub-pixel sp1 are symmetric about the second virtual line X2; in the third pixel P3, the second sub-pixels sp2 located on both sides of the first sub-pixel sp1 are symmetric about the third virtual line X3, so that the distance between the second sub-pixels sp2 of the first pixel P1 and the second sub-pixels sp2 of the other two colors adjacent to it is also approximately equal. When the second sub-pixel sp2 is lit for display, the synthesis of white dots in the display area is more uniform, and the display effect is better.

[0043] In some embodiments, the pixel P at least includes a first color pixel and a second color pixel; the emission colors of the first color pixel and the second color pixel are different; the area of the first sub-pixel sp1 of the first color pixel is S11, and the area of the first sub-pixel sp1 of the second color pixel is S21, and S11 < S21. Each sub-pixel includes a light-emitting layer, and the light-emitting layer materials of different color sub-pixels are different, so there are certain differences in the light-emitting efficiencies of different color sub-pixels. In the embodiments of the present invention, the areas of the first sub-pixels sp1 in different color pixels are set differently, which can balance the differences in the light-emitting efficiencies of the first sub-pixels sp1 of different colors, and further balance the differences in the lifetimes of the first sub-pixels sp1 of different colors, so as to make the lifetimes of the first sub-pixels sp1 equivalent as much as possible, and ensure the display effect when the first sub-pixel sp1 is lit alone for display.

[0044] Figure 9 Another partial schematic diagram of the display panel provided by the embodiments of the present invention. As Figure 9 shown, the pixel P includes a first color pixel P-1 and a second color pixel P-2 with different colors. Among them, the area of the first sub-pixel sp1 of the first color pixel P-1 is smaller than the area of the first sub-pixel sp1 of the second color pixel P-2. Optionally, the first color pixel P-1 is a green pixel, and the second color pixel P-2 is a red pixel or a blue pixel.

[0045] In some embodiments, pixel P includes a first color pixel, a second color pixel, and a third color pixel with different colors. Among them, the area of the first sub-pixel sp1 in the first color pixel is smaller than the area of the first sub-pixel sp1 in the second color pixel, and the area of the first sub-pixel sp1 in the second color pixel is smaller than the area of the first sub-pixel sp1 in the third color pixel. For example, the first color pixel is a green pixel, the second color pixel is a red pixel, and the third color pixel is a blue pixel.

[0046] In some other embodiments, the pixel includes at least a first color pixel and a second color pixel; the emission colors of the first color pixel and the second color pixel are different; the area of the second sub-pixel sp2 of the first color pixel is S12, and the area of the second sub-pixel sp2 of the second color pixel is S22, and S12 < S22. By setting the areas of the second sub-pixels sp2 in different color pixels differently in the embodiments of the present invention, the difference in the luminous efficiency of the second sub-pixels sp2 of different colors can be balanced, and further the difference in the lifetimes of the second sub-pixels sp2 of different colors can be balanced, so that the lifetimes of the second sub-pixels sp2 are as equal as possible, ensuring the display effect when the second sub-pixel sp2 is lit alone for display.

[0047] Figure 10 Another partial schematic diagram of the display panel provided by the embodiment of the present invention. As Figure 10 shown, pixel P includes a first color pixel P-1 and a second color pixel P-2 with different colors. Among them, the area of the second sub-pixel sp2 of the first color pixel P-1 is smaller than the area of the second sub-pixel sp2 of the second color pixel P-2. Optionally, the first color pixel P-1 is a green pixel, and the second color pixel P-2 is a red pixel or a blue pixel.

[0048] In some embodiments, pixel P includes a first color pixel, a second color pixel, and a third color pixel with different colors. Among them, the area of the second sub-pixel sp2 in the first color pixel is smaller than the area of the second sub-pixel sp2 in the second color pixel, and the area of the second sub-pixel sp2 in the second color pixel is smaller than the area of the second sub-pixel sp2 in the third color pixel. For example, the first color pixel is a green pixel, the second color pixel is a red pixel, and the third color pixel is a blue pixel.

[0049] In some other embodiments, Figure 11 Another partial schematic diagram of the display panel provided by the embodiment of the present invention. As Figure 11As shown, the display panel includes a first pixel P1, a second pixel P2, and a third pixel P3 of different colors. The area of ​​the first subpixel sp1 in the first pixel P1 is smaller than the area of ​​the first subpixel sp1 in the second pixel P2, and the area of ​​the first subpixel sp1 in the second pixel P2 is smaller than the area of ​​the first subpixel sp1 in the third pixel P3. The area of ​​the second subpixel sp2 in the first pixel P1 is smaller than the area of ​​the second subpixel sp2 in the second pixel P2, and the area of ​​the second subpixel sp2 in the second pixel P2 is smaller than the area of ​​the second subpixel sp2 in the third pixel P3. For example, the first pixel P1 is a green pixel, the second pixel P2 is a red pixel, and the third pixel P3 is a blue pixel.

[0050] In some embodiments, Figure 12 A partial schematic diagram of another display panel provided by an embodiment of the present invention. Figure 13 for Figure 12 A schematic cross-sectional view at the midline BB′. Figure 12 and Figure 13 As shown in FIG. 1 , the display panel includes a substrate 00 and multiple light-shielding structures 40. Each subpixel in the pixel P includes a first electrode 11, a light-emitting layer 12, and a second electrode 13. The light-emitting layer 12 is located between the first electrode 11 and the second electrode 13, and the second electrode 13 is located on the side of the first electrode 11 away from the substrate 00. The light-shielding structure 40 is located on the side of the second electrode 13 away from the substrate 00. Optionally, an encapsulation layer 03 is disposed between the light-shielding structure 40 and the second electrode 13. The encapsulation layer 03 is used to protect the subpixels from corrosion by water and oxygen. The encapsulation layer 03 includes at least one inorganic encapsulation layer and at least one organic encapsulation layer.

[0051] It can be understood that the top view direction is the same as the projection direction of the substrate 00. Figure 12 It can be seen from the top view that the orthographic projection of the light shielding structure 40 on the plane where the substrate 00 is located at least partially surrounds the orthographic projection of the first sub-pixel sp1 on the plane where the substrate 00 is located. Figure 13 It can be seen that the shading structure 40 can block the large-angle light output of the first sub-pixel sp1. When the first sub-pixel sp1 is lit alone for display, the user can view the image when facing the display panel, but cannot see the image when observing the display panel at an angle, thereby achieving an anti-peeping effect.

[0052] like Figure 13 The cross-sectional view shows that in the pixel P: along the direction f parallel to the plane of the substrate 00, the distance between the light shielding structure 40 and the first sub-pixel sp1 is smaller than the distance between the light shielding structure 40 and the second sub-pixel sp2. Figure 12The top view also shows that the light shielding structure 40 is closer to the first sub-pixel sp1 in the pixel P. This embodiment uses the light shielding structure 40 to block the wide-angle light output from the first sub-pixel sp1 while preventing the light shielding structure 40 from blocking the wide-angle light output from the second sub-pixel sp2, thereby ensuring the wide-angle light output from the second sub-pixel sp2 and ensuring a good viewing experience for the user in non-privacy protection mode.

[0053] like Figure 13 The light shielding structure 40 is shown as a ring, and surrounds the first sub-pixel sp1. In other embodiments, Figure 14 A partial schematic diagram of another display panel provided by an embodiment of the present invention. Figure 14 As shown, the display panel includes a light shielding structure 40, which is arranged around the first sub-pixel sp1 and is a non-closed pattern. Optionally, light shielding structures 40 are arranged on both sides of the first sub-pixel sp1.

[0054] In other embodiments, Figure 15 for Figure 12 Another cross-sectional diagram at the mid-tangent line BB′. Figure 15 As shown, the display panel includes a microlens 50 and a light shielding structure 40; along a plane e perpendicular to the substrate 00, the microlens 50 at least partially overlaps with the first sub-pixel sp1. The microlens 50 is located on the side of the light shielding structure 40 away from the substrate 00. The microlens 50 is a convex lens, and the surface of the microlens 50 away from the substrate 00 protrudes in the direction away from the substrate 00. The microlens 50 can deflect the transmission direction of the light, and can converge the light incident on the first sub-pixel sp1, so that the light is emitted as perpendicular to the plane e of the substrate 00 as possible. The microlens 50 allows the first sub-pixel sp1 to emit more light in the direction of the display panel, and increases the light output of the first sub-pixel sp1. At the same time, the light shielding structure 40 blocks the light output at a large angle. The microlens 50 and the light shielding structure 40 cooperate to make the display effect of the display panel better in the anti-peep mode.

[0055] In other embodiments, Figure 16 for Figure 12 Another cross-sectional diagram at the mid-tangent line BB′. Figure 16 As shown, the display panel includes a microlens 50 and a light shielding structure 40 ; along a plane e perpendicular to the substrate 00 , the microlens 50 at least partially overlaps the first sub-pixel sp1 . The microlens 50 is located on a side of the light shielding structure 40 close to the substrate 00 .

[0056] In other embodiments, Figure 17 for Figure 12 Another cross-sectional diagram at the mid-tangent line BB′. Figure 17As shown, the display panel includes a microlens 50 and a light shielding structure 40 . The microlens 50 at least partially overlaps with the first sub-pixel sp1 along a plane e perpendicular to the substrate 00 . The light shielding structure 40 at least partially surrounds the microlens 50 .

[0057] In other embodiments, Figure 18 Schematic diagram of another display panel provided by an embodiment of the present invention. Figure 18 As shown, the display panel includes a substrate 00 and a plurality of microlenses 50; the microlenses 50 are located on the side of the pixel away from the substrate 00; along a plane e perpendicular to the substrate 00, the microlenses 50 at least partially overlap with the first subpixel sp1. The microlenses 50 can deflect the propagation direction of light, converge the light incident on the first subpixel sp1, and make the light emit as perpendicular to the plane e as possible. The microlenses 50 allow the first subpixel sp1 to emit more light in the direction of normal viewing of the display panel, reduce the light emitted by the first subpixel sp1 at large angles, and increase the amount of light emitted by the first subpixel sp1 in the normal viewing direction. Lighting up the first subpixel sp1 alone for display can achieve an anti-peeping effect.

[0058] In some embodiments, Figure 19 Schematic diagram of another display panel provided by an embodiment of the present invention. Figure 19 As shown, the display panel includes a substrate 00 and a pixel definition layer 02 located on one side of the substrate 00. The pixel definition layer 02 has a first opening K1 and a second opening K2. At least a portion of the first subpixel sp1 is located in the first opening K1, and at least a portion of the second subpixel sp2 is located in the second opening K2. The angle formed by the inner wall of the first opening K1 and the plane of the substrate 00 toward the pixel definition layer 02 is a first slope angle θ1. The angle formed by the inner wall of the second opening K2 and the plane of the substrate 00 toward the pixel definition layer 02 is a second slope angle θ2. The first slope angle θ1 is greater than the second slope angle θ2. The openings where the first subpixel sp1 and the second subpixel sp2 are located have different slope angles. The second slope angle θ2 corresponding to the second subpixel sp2 is set to a smaller angle. This ensures that the second subpixel sp2 emits light at a large oblique angle. When the second subpixel sp2 is illuminated for display, a wide-angle viewing effect is guaranteed. Setting the first slope angle θ1 corresponding to the first sub-pixel sp1 to a smaller angle can reduce the light emitted by the first sub-pixel sp1 at large oblique angles, so that the first sub-pixel sp1 can emit more light in the direction facing the display panel. The design of the first slope angle θ1 is combined with the shading structure 40 and / or the microlens 50 to improve the display effect in the anti-peep mode.
