[0025] In related technologies, in Micro OLED display panels, light emitted from sub-pixels can be focused from a large angle to a small angle through the converging effect of lenses to improve brightness. Micro OLED display panels are commonly used in Virtual Reality (VR) display products, with appropriate lens structures paired according to the light emission angle type of the display panel. Pancake optical engines with folded optical paths are generally paired with outward-expanding principal ray angle (CRA) lenses for imaging, meaning the principal ray is deflected outwards from the center to the edge of the screen and then reflected into the pancake optical engine. Aspherical lenses and Fresnel lenses are generally paired with inward-retracting CRA lenses for imaging, meaning the principal ray is deflected inwards from the center to the edge of the screen. However, both outward-expanding and inward-retracting CRA panels require a large number of lenses, resulting in a large overall size of the display product, affecting the user experience and making it difficult to reduce costs.

[0026] This application provides a display panel, such as... Figure 1 , Figure 2 As shown, the display panel includes: The substrate 1 includes a display area AA and a peripheral area NA surrounding the display area AA; the display area AA includes: a first area AA1 and a second area AA2 located between the first area AA1 and the peripheral area NA; the second area AA2 surrounds the first area AA1, and the center of the first area AA1, the center of the second area AA2 and the center Z0 of the display area AA coincide. Multiple pixels PX are located in display area AA; pixel PX includes multiple sub-pixels S; the direction in which the light emitted from sub-pixels S has the strongest light intensity is a first light emission direction T1; in one of the first regions AA1 and the second region AA2, at least part of the angle between the first light emission direction T1 and the direction Z- away from the center Z0 of display area AA is less than 90 degrees. In the other of the first region AA1 and the second region AA2, the angle between at least part of the first light-emitting direction T1 and the direction Z+ toward the center Z0 of the display area AA is less than 90 degrees. .

[0027] It should be noted that the light emitted from the direction with the strongest light intensity from a sub-pixel is the main ray of that sub-pixel; that is, the first emission direction is the emission direction of the main ray of the sub-pixel. As shown in the figure, when the angle between the first emission direction T1 and the direction away from the center Z0 of the display area AA is less than 90 degrees... When the first light-emitting direction T1 is deflected away from the center Z0 of the display area AA, this type of main ray is called an outward-expanding ray. When the angle between the first light-emitting direction T1 and the direction towards the center Z0 of the display area AA is less than 90 degrees... That is, the first light-emitting direction T1 is deflected towards the center Z0 side closer to the display area AA. This type of main light is called an inward-facing light.

[0028] The display panel provided in this application embodiment has different light emission directions (i.e., the deflection directions of the first light emission direction) for the main light rays of the sub-pixels in the first and second regions. At least some sub-pixels in the first region have outward-expanding main light rays, and at least some sub-pixels in the second region have inward-converging main light rays; alternatively, at least some sub-pixels in the second region have outward-expanding main light rays, and at least some sub-pixels in the first region have inward-converging main light rays. That is, the main light rays of the display panel are no longer a single deflection type. When the display panel is applied to a display product, and when a lens structure needs to be set on the light emission side of the display panel, it is beneficial to reduce the number of lens structures, thereby reducing the overall size of the display product and improving the user experience.

[0029] It should be noted that, Figure 2 Only a portion of the first region A1 and the second region A2 are shown in the image. Figure 2 The angle between at least a portion of the first light-emitting direction T1 in the first region AA1 and the direction Z- away from the center Z0 of the display area AA is less than 90 degrees. In the second region AA2, the angle between at least part of the first light-emitting direction T1 and the direction Z+ toward the center Z0 of the display area AA is less than 90 degrees. Let's take an example to illustrate. That is, in the first region, at least some of the sub-pixels have outward-spreading main rays, and in the second region, at least some of the sub-pixels have inward-spreading rays.

In the direction away from the center Z0 of the display area AA, the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 decreases, the absolute value of the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 decreases, the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 decreases, and the absolute value of the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 increases; or, In the direction away from the center Z0 of the display area AA, the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 increases, the absolute value of the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 decreases, the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 increases, and the absolute value of the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 increases.

[0053] The display panel provided in this application embodiment has a first angle whose absolute value first increases and then decreases from the center of the display area to the edge of the first sub-region away from the center of the display area, decreasing to 0 in the second sub-region. From the edge of the third sub-region toward the center of the display area to the edge of the second region away from the center of the display area, the absolute value of the first angle increases. This achieves a reversal of the positive and negative values ​​of the first angle on both sides of the second sub-region, reducing the design difficulty of the inverted CRA panel.

[0054] In some embodiments, such as Figure 2 As shown, when the angle between at least part of the first light-emitting direction T1 in the first region AA1 and the direction Z- away from the center Z0 of the display area AA is less than 90 degrees. The angle between at least part of the first light-emitting direction T1 of the second region AA2 and the direction Z+ toward the center Z0 of the display area AA is less than 90 degrees. Then the angle between the first light-emitting direction T1 of the first sub-region AA31 and the direction Z- away from the center Z0 of the display area AA is less than 90 degrees. The angle between the first light-emitting direction T1 of the third sub-region AA33 and the direction Z+ towards the center Z0 of the display area AA is less than 90 degrees. That is, at least some sub-pixels S in the first region AA1 and the first sub-region AA31 have a positive first angle a1, while the first angle a1 corresponding to the sub-pixels S in the second region AA2 and the third sub-region AA33 is negative. In the direction away from the center Z0 of the display area AA, the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 decreases, the absolute value of the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 decreases, the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 decreases, and the absolute value of the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 increases.

[0055] In other words, in the direction away from the center of the display area, from the center of the display area to the edge of the first sub-region away from the center of the display area, the first angle first increases and then decreases, and the absolute value of the first angle first increases and then decreases. In the second sub-region, the absolute value of the first angle decreases to 0. From the edge of the third sub-region towards the center of the display area to the edge of the second region away from the center of the display area, the first angle decreases and the absolute value of the first angle increases. This reverses the positive and negative values ​​of the first angle on both sides of the second sub-region, reducing the design difficulty of the inverted CRA panel.

[0056] Alternatively, in some embodiments, when the angle between at least a portion of the first light-emitting direction in the second region and the direction away from the center of the display area is less than 90 degrees. The angle between at least a portion of the first light-emitting direction in the first region and the direction toward the center of the display area is less than 90 degrees. Then the angle between the first light-emitting direction of the third sub-region and the direction Z- away from the center of the display area is less than 90 degrees. The angle between the first light-emitting direction of the first sub-region and the direction toward the center of the display area is less than 90 degrees. That is, at least some sub-pixels in the first region and the first angle a1 corresponding to the sub-pixels of the first sub-region are negative, while the first angle a1 corresponding to the sub-pixels of the second region and the third sub-region is positive. In the direction away from the center Z0 of the display area AA, the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 increases, the absolute value of the first angle a1 corresponding to different pixel groups PZ of the first sub-region AA31 decreases, the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 increases, and the absolute value of the first angle a1 corresponding to different pixel groups PZ of the third sub-region AA33 increases.

[0057] In other words, in the direction away from the center of the display area, from the center of the display area to the edge of the first sub-region away from the center of the display area, the first angle first decreases and then increases, and the absolute value of the first angle first increases and then decreases. In the second sub-region, the absolute value of the first angle decreases to 0. From the edge of the third sub-region towards the center of the display area to the edge of the second region away from the center of the display area, the first angle increases, and the absolute value of the first angle also increases. This reverses the positive and negative values ​​of the first angle on both sides of the second sub-region, reducing the design difficulty of the inverted CRA panel.

[0058] In some embodiments, the area of ​​the first region is greater than the area of ​​the second region, and the area of ​​the first region is greater than the area of ​​the third region.

[0059] In some embodiments, the area of ​​the second region is larger than the area of ​​the third region.

[0060] In some embodiments, the area of ​​the first region is 50% of the total area of ​​the display area, the area of ​​the second region is 30% of the total area of ​​the display area, and the area of ​​the third region is 20% of the total area of ​​the display area.

[0061] In some embodiments, such as Figure 1 , Figure 2 As shown, the first region AA1 includes a fourth sub-region AA11 and a fifth sub-region AA12. The fifth sub-region AA12 surrounds the fourth sub-region AA11. The fourth sub-region AA11 includes the center Z0 of the display area AA. In the fourth sub-region AA11, the first angle a1 of the sub-pixel S is 0. The absolute value of the first angle a1 in the fifth sub-region AA12 sub-pixel S is greater than 0. .

[0062] In some embodiments, in the display panel, the number of pixels in a row PZ arranged along the first direction X is x1, and the number of pixels in a column PZ arranged along the second direction Y is y1, wherein the first direction X and the second direction Y intersect; within the pixel group PZ, the number of pixels in a row PX arranged along the first direction X is... The number of pixels PX arranged in a row along the second direction Y is The number of pixels PX arranged in a row along the first direction X in the display panel is m, and the number of pixels PX arranged in a row along the first direction X in the display panel is n; the width of pixel PX in the first direction X is a, and the width of pixel PX in the second direction Y is b. like Figure 6 As shown, the display panel also includes a plurality of dummy pixels PX' located in the peripheral area NA; the total number of dummy pixels PX' located on both sides of a row of pixels PX in the display area AA in the first direction X is w1, and the total number of dummy pixels PX' located on both sides of a column of pixels PX in the display area AA in the second direction Y is w2. x1 and y1 satisfy: x1= ; y1= .

[0063] It should be noted that a virtual pixel includes multiple virtual sub-pixels; a virtual sub-pixel includes a virtual light modulation structure and a virtual light-emitting device; when a sub-pixel includes a color filter, the virtual sub-pixel also includes a virtual color filter; therefore, the surrounding area also needs to have patterns of virtual light-emitting devices, virtual color filters, and virtual light modulation structures. Each film layer of the virtual light-emitting device is set on the same layer as each film layer of the light-emitting device, the virtual color filter is set on the same layer as the color filter, and the virtual light modulation structure is set on the same layer as the light modulation structure. This can avoid the thickness of each film layer of the sub-pixels at the edge of the display area being different from the thickness of the central area of ​​the display area, which is beneficial to improving the thickness uniformity of each film layer of the sub-pixel and improving the display effect of the display area.

[0064] In some embodiments, x1 and y1 are positive integers. This divides all pixels within the display area into an integer number of pixel groups, ensuring that the first angle is not exactly the same for pixel groups at different positions and heights. Furthermore, the use of dummy pixels also guarantees that x1 and y1 obtained from the above formula are positive integers.

[0065] In some embodiments, = .

[0066] In some embodiments, such as Figures 2-4 As shown, the surface of the optical modulation structure 4 facing away from the substrate 1 is curved; The center of the light modulation structure 4 in the orthographic projection of the substrate 1 is the first center O1, and the center of the light-emitting area of ​​the light-emitting device 3 in the orthographic projection of the substrate 1 is the second center O2; in at least a part of the first region AA1 and one of the second regions AA2, the first center O1 is located on the side of the second center O2 facing the center Z0 of the display area AA; in the other part of the first region AA1 and the second region AA2, the first center O1 is located on the side of the second center O2 away from the center Z0 of the display area AA.

[0067] In the display panel provided in this application embodiment, in at least a portion of the display area, the first center of the light modulation structure does not coincide with the second center of the light-emitting area of ​​the light-emitting device, thereby enabling at least a portion of the sub-pixels to have an angle greater than 0° between their first light-emitting direction and the direction perpendicular to the plane of the display panel. Furthermore, by adjusting the positions of the first and second centers, the light emission direction (i.e., the deflection direction of the first light emission direction) of the sub-pixel's main light rays can be made different in the first and second regions. This ensures that the main light rays of the display panel are no longer subject to a single deflection type. When the display panel is used in display products, and lens structures are required on the light-emitting side of the display panel, this reduces the number of lens structures, thereby reducing the overall size of the display product and improving the user experience.

[0068] In some embodiments, such as Figure 2As shown, the second center O2 coincides with the center of the orthographic projection of the first electrode 310 onto the substrate 1.

[0069] In some embodiments, in at least a portion of the first region AA1, the first center O1 is located on the side of the second center O2 away from the center Z0 of the display area AA, and the angle between the first light emission direction T1 and the direction Z- away from the center Z0 of the display area AA is less than 90 degrees. ; In the second region A2, the first center O1 is located on the side of the second center O2 facing the center Z0 of the display area AA, and the angle between the first light-emitting direction T1 and the direction Z+ facing the center Z0 of the display area AA is less than 90 degrees. .

[0070] Alternatively, in some embodiments, in at least a portion of the first region, the first center is located on the side of the second center facing the center of the display area, and the angle between the first light-emitting direction and the direction facing the center of the display area is less than 90 degrees. ; In the second region, the first center is located on the side of the second center away from the center of the display area, and the angle between the first light-emitting direction and the direction away from the center of the display area is less than 90 degrees. .

[0071] In some embodiments, such as Figure 2 , Figure 4 As shown, in the fourth sub-region AA11, the first center O1 and the second center O2 coincide; in the fifth sub-region AA12, the first center O1 and the second center O2 do not coincide. Figure 2 The example given is that in the fifth sub-region AA12, the first center O1 is located on the side of the second center O2, away from the center Z0 of the display area AA. In the second sub-region AA32, the first center O1 coincides with the second center O2; In the first sub-region AA31 and the first region AA1, the first center O1 is located on the same side as the second center O2; Figure 4 In the first sub-region AA31, the first center O1 is located on the side of the second center O2, away from the center Z0 of the display area AA; In the third sub-region AA33 and the second region AA2, the first center O1 is located on the same side as the second center O2; Figure 2 , Figure 4 In the third sub-region AA33 and the second region AA2, the first center O1 is located on the side of the second center O2 facing the center Z0 of the display area AA; The distance between the first center O1 and the second center O2 of a sub-pixel S is the first distance H1; the first distance H1 of the same pixel group PZ is the same; that is, in the fourth sub-region A11 and the second sub-region A32, the first distance H1 is 0, and in the fifth sub-region A12, the first sub-region AA31, the third sub-region AA33 and the second region AA2, the first distance H1 is greater than 0. In the direction away from the center Z0 of the display area AA, the first spacing H1 of the pixel group PZ of the first region AA1 increases, and the first spacing H1 of the pixel group PZ of the first sub-region AA31 decreases. In the direction away from the center Z0 of the display area AA, the first spacing H1 of the pixel group PZ in the third sub-region AA33 and the second region AA2 increases.

[0072] The display panel provided in this application embodiment has the following characteristics: in the direction away from the center of the display area, from the center of the display area to the edge of the first region away from the center of the display area, the first spacing increases from 0; from the edge of the first region away from the center of the display area to the edge of the first sub-region away from the center of the display area, the first spacing decreases; and the first spacing is 0 in the second sub-region. From the edge of the third sub-region toward the center of the display area to the edge of the second region away from the center of the display area, the first spacing increases.

[0073] In some embodiments, the first spacing of the pixel group in the first sub-region is smaller than the first spacing of the pixel group in a portion of the fifth sub-region.

[0074] In some embodiments, the first spacing of the pixel group in the third sub-region is smaller than the first spacing of the pixel group in a portion of the second region.

[0075] In some embodiments, at least in a portion of the area, the orthographic projection of the light-emitting device onto the substrate overlaps with the orthographic projection of the color filter and / or light modulation structure of the adjacent sub-pixel onto the substrate.

[0076] In some embodiments, the first spacing is less than or equal to This avoids excessive overlap between the light-emitting device and the color filter and / or light modulation structure of adjacent sub-pixels, which could lead to crosstalk between adjacent sub-pixels.

[0077] It should be noted that when the surface of the light modulation structure facing away from the substrate is curved, that is, the light modulation structure is a convex lens, the offset direction of the light modulation structure is reversed in the third region. If the reverse offset is too large, it will easily cause the spacing between adjacent light modulation structures to be too small, making the lens difficult to manufacture. During the manufacturing process, the problem of adjacent lenses sticking together is likely to occur, which will affect the yield of the display panel and the display effect.

[0078] In some embodiments, the spacing HS between two adjacent optical modulation structures needs to satisfy: HS ≥ HS_min; Wherein, HS_min is the minimum value under process constraints in the fabrication process of the optical modulation structure; In the third region, the number of pixel groups between adjacent image heights is ; In the third region, the offset difference between adjacent image heights is vu; These are the offsets of adjacent image heights in the third region relative to their respective second centers; In the third region, the relative offset of each pixel group within adjacent image heights is: ; Therefore, in the third region, HS also needs to satisfy: HS= ; in, This is a preset reference value for the spacing between two adjacent optical modulation structures.

[0079] Based on the conditions satisfied by HS above, and given that u, v, j, a, HS_min, and HS_spec are determined, the maximum reversible offset between adjacent image heights can be determined while ensuring that adjacent convex lenses do not stick together. In some embodiments, HS_spec = 0.5 micrometers (μm) and HS_min = 0.4 μm. It can be seen that a relatively large CRA angle reversal can be performed within 1 millimeter (mm). However, in actual design, specific designs can be made based on factors such as lens deflection and imaging.

[0080] In some embodiments, such as Figure 6 As shown, the display panel also includes a plurality of dummy pixels PX' located in the peripheral area NA; the plurality of dummy pixels PX' includes a first dummy pixel PX1'.

[0081] In some embodiments, in the first dummy pixel, the center of the orthographic projection of the dummy light modulation structure onto the substrate does not coincide with the center of the orthographic projection of the light-emitting area of ​​the dummy light-emitting device onto the substrate.

[0082] In some embodiments, such as Figure 6 As shown, the plurality of dummy pixels PX' include a second dummy pixel PX2' located on the side of the first dummy pixel PX1' away from the display area AA.

[0083] In some embodiments, in the second dummy pixel, the center of the dummy light modulation structure in the orthographic projection of the substrate coincides with the center of the light-emitting area of ​​the dummy light-emitting device in the orthographic projection of the substrate.

[0084] In some embodiments, the plurality of dummy pixels includes a plurality of first dummy pixels and / or a plurality of second dummy pixels.

[0085] It should be noted that when the dummy pixel only includes the first dummy pixel, w1 and w2 are the number of the first dummy pixel; when the dummy pixel only includes the second dummy pixel, w1 and w2 are the number of the second dummy pixel; when the dummy pixel includes both the first dummy pixel and the second dummy pixel, w1 is the sum of the number of the first dummy pixel and the second dummy pixel, and w2 is the sum of the number of the first dummy pixel and the second dummy pixel.

[0086] In some embodiments, such as Figure 5 As shown, the surface of the optical modulation structure 4 facing away from the substrate 1 is the first inclined surface Q1, and the angle between the first inclined surface Q1 and the right angle of the plane containing the substrate 1 is greater than 0°. And less than 90 ; The center of the optical modulation structure 4 in the orthographic projection of the substrate 1 is the first center O1, and the center of the light-emitting area of ​​the light-emitting device 3 in the orthographic projection of the substrate 1 is the second center O2. The first center O1 and the second center O2 coincide. The light modulation structure 4 also includes a first side surface Q2 connected to the first inclined surface Q1; the connection between the first inclined surface Q1 and the first side surface Q2 is further away from the substrate 1 than the end of the first inclined surface Q1 that is further away from the first side surface Q2; in at least a part of the first region AA1 and the second region AA2, the first inclined surface Q1 is located on the side of the first side surface Q2 facing the center Z0 of the display area AA, and in the other part of the first region AA1 and the second region AA2, the first inclined surface Q1 is located on the side of the first side surface Q2 that is further away from the center Z0 of the display area AA.

[0087] The display panel provided in this application embodiment has a light modulation structure including a first inclined surface in at least a portion of the display area, thereby enabling the angle between the first light emission direction of the sub-pixels in at least a portion of the area and the direction perpendicular to the plane of the display panel to be greater than 0. Furthermore, by adjusting the tilt angle of the first inclined surface and its positional relationship with the first side surface, the deflection direction of the main light ray emitted by the sub-pixels (i.e., the first light emission direction) can be different in the first and second regions. This ensures that the main light ray of the display panel is no longer a single type of deflection. When the display panel is used in display products, and when a lens structure needs to be set on the light emission side of the display panel, this helps to reduce the number of lens structures, thereby reducing the overall size of the display product and improving the user experience.

[0088] In some embodiments, such as Figure 5 As shown, in at least a portion of the first region AA1, the first inclined plane Q1 is located on the side of the first side plane Q2 facing the center Z0 of the display area AA, and the angle between the first light emission direction T1 and the direction Z- away from the center Z0 of the display area AA is less than 90 degrees. ; In the second region A2, the first inclined plane Q1 is located on the side of the first side Q2 away from the center Z0 of the display area AA, and the angle between the first light-emitting direction T1 and the direction Z+ toward the center Z0 of the display area AA is less than 90 degrees. .

[0089] Alternatively, in some embodiments, in at least a portion of the first region, the first inclined surface is located on the side of the first side away from the center of the display area, and the angle between the first light-emitting direction and the direction toward the center of the display area is less than 90 degrees. ; In the second region, the first inclined surface is located on the side of the first side facing the center of the display area, and the angle between the first light-emitting direction and the direction away from the center of the display area is less than 90 degrees. .

[0090] In some embodiments, such as Figure 5 As shown, the optical modulation structure 4 also includes a first inclined surface Q1 and a first bottom surface Q3 connected to the first side surface Q2, that is, one end of the first inclined surface Q1 is connected to the first side surface Q2, and the other end of the first inclined surface Q1 is connected to the first bottom surface Q3.

[0091] In some embodiments, such as Figure 5 As shown, the first side surface Q2 is perpendicular to the first bottom surface Q3.

[0092] In some embodiments, such as Figure 5 As shown, the angle between the first inclined plane Q1 and the plane in which the display panel is located is the second angle a2; The second angle a2 is the same as that of the seed pixel S in different pixel groups PZ of the second sub-region AA32; In the direction away from the center Z0 of the display area AA, the second angle a2 of the same seed pixel S in different pixel groups PZ of the first region AA1 increases, the second angle a2 of the same seed pixel S in different pixel groups PZ of the first sub-region AA31 decreases, the second angle a2 of the same seed pixel S in different pixel groups PZ of the second sub-region AA32 increases, and the second angle a2 of the same seed pixel S in different pixel groups PZ of the second region AA2 increases.

[0093] In some embodiments, the second angle a2 of different sub-pixels S in the fourth sub-region AA11 pixel group PZ is the same; In at least a portion of at least one of the fifth sub-region AA12, the second sub-region AA2, and the third sub-region AA3, the second angle a2 of different sub-pixels S in pixel PX is different. This can balance the brightness differences of sub-pixels in different positions and pixels, thus improving the display effect.

[0094] In some embodiments, such as Figure 5As shown, in at least a portion of the fifth sub-region AA12, in a pixel PX, the second angle a2 of the second sub-pixel S2 is less than the second angle a2 of the third sub-pixel S3, and the second angle a2 of the third sub-pixel S3 is less than the second angle a2 of the first sub-pixel S1.

[0095] In some embodiments, such as Figure 5 As shown, in at least a portion of the second region AA2, in a pixel PX, the second angle a2 of the first sub-pixel S1 is less than the second angle a2 of the third sub-pixel S3, and the second angle a2 of the third sub-pixel S3 is less than the second angle a2 of the second sub-pixel S2.

[0096] In some embodiments, such as Figure 5 As shown, in the fourth sub-region AA11, the positional relationship between the first inclined surface Q1 and the first side surface Q2 of different sub-pixels S is not entirely the same. That is, in the fourth sub-region AA11, the first inclined surface Q1 of some sub-pixels S is located on the side of the first side surface Q2 facing the center Z0 of the display area AA, while the first inclined surface Q1 of some sub-pixels S is located on the side of the first side surface Q2 away from the center Z0 of the display area AA.

[0097] In some embodiments, such as Figures 2-5 As shown, the center of the orthographic projection of the light modulation structure 4 onto the substrate 1 is the first center O1, and the center of the orthographic projection of the color filter 5 onto the substrate 1 is the third center O3, which coincides with the first center O1.

[0099] The display device provided in this application embodiment has different light emission directions (i.e., the deflection directions of the first light emission direction) for the main light rays of the sub-pixels in the first and second regions of the display panel. At least some sub-pixels in the first region have outward-expanding main light rays, and at least some sub-pixels in the second region have inward-retracting main light rays; alternatively, at least some sub-pixels in the second region have outward-expanding main light rays, and at least some sub-pixels in the first region have inward-retracting main light rays. That is, the main light rays of the display panel are no longer a single deflection type. This helps reduce the number of lens structures, thereby reducing the overall size of the display device and improving the user experience.

[0100] In some embodiments, such as Figure 7 As shown, the lens structure 7 includes a first lens region 701 and a second lens region 702 surrounding the first lens region 701; the first lens region 701 includes the center of the lens structure 7.

In the second region AA2, the angle between the first light-emitting direction and the direction toward the center of the display area AA is less than or equal to 90 degrees. ; The surface of the first lens area 701 facing the display panel 6 is a curved surface that bulges out towards the display panel 6; The minimum distance h5 between the first lens area 701 and the display panel 6 is less than the minimum distance h6 between the second lens area 702 and the display panel 6.

[0102] In some embodiments, such as Figure 7 As shown, the surface of the second lens area 702 facing the display panel 6 is flat.

[0103] In some embodiments, such as Figure 7 As shown, in the second direction Y, the maximum width h2 of the first region AA1 is less than the maximum width h4 of the first lens region 701, the width h1 of the display panel 6 is greater than the maximum width h4 of the first lens region 701, and the width h1 of the display panel 6 is less than the maximum width h3 of the lens structure 7.

[0104] In some embodiments, .

[0105] Alternatively, in some embodiments, such as Figure 8 As shown, the angle between the first light-emitting direction in the second region AA2 and the direction away from the center of the display area AA is less than or equal to 90 degrees. In the first region AA1, the angle between the first light-emitting direction and the direction toward the center of the display area AA is less than or equal to 90 degrees. ; The surface of the second lens area 702 facing the display panel 6 is a curved surface that bulges out towards the display panel 6; The minimum distance h5 between the first lens area 701 and the display panel 6 is greater than the minimum distance h6 between the second lens area 702 and the display panel 6.

[0106] In some embodiments, such as Figure 8 As shown, in the second direction Y, the maximum width h2 of the first region AA1 is greater than the maximum width h4 of the first lens region 701, the maximum width h2 of the first region AA1 is less than the maximum width h3 of the lens structure 7, and the width h1 of the display panel 6 is less than the maximum width h3 of the lens structure 7.

Implementation of this display device can be referred to the above-described display panel embodiment; repeated details will not be elaborated upon.

[0109] In summary, the display panel and display device provided in this application have different light emission directions (i.e., the deflection directions of the first light emission direction) for the main light rays of the sub-pixels in the first and second regions. At least some sub-pixels in the first region have outward-expanding main light rays, and at least some sub-pixels in the second region have inward-retracting main light rays; or, at least some sub-pixels in the second region have outward-expanding main light rays, and at least some sub-pixels in the first region have inward-retracting main light rays. That is, the main light rays of the display panel are no longer a single deflection type. When the display panel is applied to a display product, if a lens structure needs to be set on the light emission side of the display panel, it is beneficial to reduce the number of lens structures, thereby reducing the overall size of the display product and improving the user experience.
