Display panel and display device

Abstract

A display panel includes a light-transmitting opening, which comprises a first light-transmitting segment. The line connecting the midpoint of the first light-transmitting segment and the center of the light-transmitting opening is a light-transmitting rotation line. The angle between different light-transmitting rotation lines and a first direction is a light-transmitting rotation angle. In the same light-transmitting opening, at least some of the first light-transmitting segments have different light-transmitting rotation angles. By controlling the light-transmitting rotation angle, the position of the first light-transmitting segment at the edge of the light-transmitting opening can be controlled, thereby changing the amount of light transmitted at different positions on the edge of different light-transmitting openings. This causes the reflected light from ambient light to produce a destructive interference effect when passing through different light-transmitting openings, reducing or eliminating the possibility of color separation in visual effects. This invention also provides a display device including the above-described display panel.

Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology

[0002] By forming a color filter layer on the encapsulation layer (COE, Color On Encapsulation), the polarizer is removed, making the display panel thinner, increasing light transmittance, and thus reducing power consumption.

[0003] Ambient light reflected at the edge of the light-transmitting opening will diffract. Since different colors of light have different wavelengths, different colors of light will produce different diffracted light waves. The diffracted light waves from different light-transmitting openings will interfere and enhance to form diffracted halos of different colors, resulting in color separation in the visual effect.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art.

Detailed Implementation

[0062] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted. Furthermore, the drawings are merely illustrative of the present invention and are not necessarily drawn to scale.

[0063] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0064] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0065] FMLOC (Flexible Multi-Layer On Cell) design is currently mainstream in the OLED touch display field. FMLOC design refers to fabricating a metal electrode layer on the encapsulation layer 17 of the display substrate. The surface of this metal electrode layer significantly reflects ambient light. To improve the contrast of the display panel and reduce reflected light, a polarizer is typically placed on the light-emitting side of the light-emitting layer 16 so that the display panel appears black when it is not lit. However, the polarizer causes a decrease in the light intensity of the display panel and results in a larger display panel thickness.

[0066] like Figure 1 As shown, in order to reduce the thickness of the display panel and improve the light emission gain, a color filter layer is set on the light emission side of the light-emitting layer 16 to replace the polarizer. The color filter layer is still located on the side of the encapsulation layer 17 away from the driving backplate 10. The color filter layer includes a light-shielding layer 19 and a light-filtering layer 21. Most of the ambient light is absorbed by the light-shielding layer 19, and there is no light intensity attenuation in the light emission area of ​​the light-emitting layer 16. The emitted light is emitted directly from the light-filtering layer 21, thereby improving the light emission gain of the display panel. However, this will cause the emitted light from the light-emitting unit 162 with a large oblique angle to directly enter the light-shielding layer 19, resulting in a low utilization rate of the emitted light and a large power consumption of the display panel.

[0067] like Figure 2 As shown, in order to improve the light emission efficiency of the display panel from the front viewing angle, a first cover layer 20 is provided on the side of the touch electrode layer away from the driving back plate 10. The first cover layer 20 includes a plurality of first cover portions 205. The touch electrode layer includes a plurality of touch units. The first cover portions 205 are provided on the side of the first touch unit 1811 away from the driving back plate 10. The first cover portions 205 cover the first touch unit 1811. A dimming opening 201 is formed between the sides of the first cover portions 205 that are close to each other. A light-shielding layer 19 is provided on the side of the first cover layer 20 away from the drive back plate 10. The light-shielding layer 19 includes a plurality of light-shielding parts 191. A light-transmitting opening 192 is formed between the sides of the light-shielding parts 191 that are close to each other. A first filter unit 211, a second filter unit 212 and a third filter unit 213 of different colors are provided in each dimming opening 201. The first filter unit 211, the second filter unit 212 and the third filter unit 213 cover the side of the first cover part 205 and extend to the side of the first cover part 205 away from the substrate 11.

[0068] Because the width and thickness of the first touch unit 1811 are relatively small, the side of the first cover portion 205 is beveled. The refractive indices of the first filter unit 211, the second filter unit 212, and the third filter unit 213 are greater than the refractive index of the first cover portion 205. Therefore, the light emitted from the light-emitting unit 162 at an oblique angle can undergo total internal reflection at the interface between the side of the first cover portion 205 and the first filter unit 211, the second filter unit 212, and the third filter unit 213, deflecting the light emitted from the oblique angle to the direction of the normal angle, thus improving the light emission efficiency of the display panel at the normal angle. Therefore, there is no need to set a polarizer, reducing the thickness of the display panel and contributing to the thinning of the display panel.

[0069] But regardless Figure 1 still Figure 2 In the display panel, reflected ambient light diffracts at the edge of the light-transmitting opening 192. Because different colors of light have different wavelengths, they produce different diffracted light waves. The diffracted light waves from different light-transmitting openings 192 interfere and enhance each other, forming diffraction rings of different colors, resulting in a color separation phenomenon in the visual effect. For example... Figure 3 As shown, when light of the same color is diffracted at the edge of the light-transmitting opening 192, multiple diffraction rings that gradually diffuse outward will be formed, and the diffraction rings have relatively clear boundaries.

[0070] Based on this, the present invention provides a display panel. For example... Figures 4 to 20 As shown, the display panel includes a driving backplate 10, a pixel defining layer 15, and a light-shielding layer 19. The pixel defining layer 15 is disposed on one side of the driving backplate 10 and has different types of pixel openings 151. The light-shielding layer 19 is disposed on the side of the pixel defining layer 15 away from the driving backplate 10 and has different types of light-transmitting openings 192. The orthographic projection of the pixel openings 151 on the driving backplate 10 lies within the orthographic projection of the light-transmitting openings 192 on the driving backplate 10. The edges of the light-transmitting openings 192 have a first... The light-transmitting segment and the light-transmitting opening 192 are defined as follows: the distance between the first light-transmitting segment and the center of the light-transmitting opening 192 is the first light-transmitting distance; the distance between the second light-transmitting segment and the center of the light-transmitting opening 192 is the second light-transmitting distance; the second light-transmitting distance is not equal to the first light-transmitting distance; the line connecting the midpoint of the first light-transmitting segment and the center of the light-transmitting opening 192 is the light-transmitting rotation line; the angle between different light-transmitting rotation lines and the first direction OA is the light-transmitting rotation angle; in the same type of light-transmitting opening 192, at least some of the first light-transmitting segments have different light-transmitting rotation angles.

[0071] The line connecting the midpoint of the first light-transmitting segment and the center of the light-transmitting opening 192 is the light-transmitting rotation line. The angle between different light-transmitting rotation lines and the first direction OA is the light-transmitting rotation angle. In the same type of light-transmitting opening 192, at least some of the first light-transmitting segments have different light-transmitting rotation angles. By controlling the light-transmitting rotation angle, the position of the first light-transmitting segment at the edge of the light-transmitting opening 192 can be controlled to be different, thereby changing the amount of light transmitted at different positions on the edge of different light-transmitting openings 192. This causes the reflected light from the ambient light to produce a destructive interference effect when passing through different light-transmitting openings 192, reducing or eliminating the possibility of color separation in visual effects.

[0072] The display panel involved in the embodiments of this utility model will be described in detail below with reference to specific examples.

[0073] like Figure 4 As shown, a display panel may generally include a substrate 11 and a driving circuit layer 13. The driving circuit layer 13 is disposed on one side of the substrate 11. The display panel may also include a buffer layer 12, which is disposed between the substrate 11 and the driving circuit layer 13.

[0074] The substrate 11 can be an inorganic material or an organic material. For example, in one embodiment of this invention, the substrate 11 can be made of glass materials such as soda-lime glass, quartz glass, or sapphire glass, or it can be made of metal materials such as stainless steel, aluminum, or nickel.

[0075] In another embodiment of the present invention, the substrate 11 may also be a flexible substrate 11, for example, the material of the substrate 11 may be polyimide (PI). The substrate 11 may also be a composite of multiple materials. For example, in one embodiment of the present invention, the substrate 11 may include a bottom film, a pressure-sensitive adhesive layer, a first polyimide layer and a second polyimide layer stacked sequentially.

[0076] The driving circuit layer 13 is provided with a driving circuit for driving the light-emitting unit 162. The driving circuit is located in the display area, and any driving circuit can include a transistor, which can be a thin-film transistor (TFT). The TFT can be selected from top-gate TFTs, bottom-gate TFTs, or dual-gate TFTs. Taking a top-gate TFT as an example, the driving circuit layer 13 may include a first active layer 131, a first gate insulating layer 1321, a first gate 1331 layer, a second gate insulating layer 1322, a second gate 1332 layer, and a first source / drain metal layer, sequentially disposed along a direction away from the substrate 11, wherein:

[0077] The first active layer 131 is disposed on one side of the substrate 11. The material of the first active layer 131 can be amorphous silicon semiconductor material, low-temperature polycrystalline silicon semiconductor material, metal oxide semiconductor material, organic semiconductor material, or other types of semiconductor material. Therefore, the thin film transistor can be an N-type thin film transistor or a P-type thin film transistor. The first active layer 131 may include a channel region and two doped regions of different doping types located on both sides of the channel region.

[0078] The first gate insulating layer 1321 is disposed on the side of the active layer 131 away from the substrate 11. The first gate insulating layer 1321 can cover the active layer 131 and the substrate 11. The first gate 1331 layer can include the first gate 1331. The first gate 1331 is disposed on the side of the first gate insulating layer 1321 away from the substrate 11 and is directly opposite to the active layer 131. That is, the projection of the first gate 1331 on the substrate 11 is located within the projection range of the active layer 131 on the substrate 11. For example, the projection of the first gate 1331 on the substrate 11 coincides with the projection of the channel region of the active layer 131 on the substrate 11. The second gate insulating layer 1322 is disposed on the side of the first gate 1331 away from the substrate 11. The second gate insulating layer 1322 can cover the first gate 1331 and the first gate insulating layer 1321. The second gate 1332 layer can include the second gate 1332, which is disposed on the side of the second gate insulating layer 1322 away from the substrate 11 and is directly opposite the active layer 131. The materials of the first gate insulating layer 1321 and the second gate insulating layer 1322 are both insulating materials such as silicon oxide.

[0079] The thin-film transistor may further include an interlayer dielectric layer 134, which is disposed on the side of the second gate 1332 away from the substrate 11, and may cover the second gate 1332 and the second gate insulating layer 1322. A first source / drain metal layer is disposed on the surface of the interlayer dielectric layer 134 away from the substrate 11, and may include a first source 135 and a drain 136, which are connected to the first active layer 131. For example, the first source 135 and the drain 136 are respectively connected to two doped regions of the corresponding first active layer 131 through vias. A protective layer 137 may also be provided on the side of the first source 135 away from the substrate 11, and the protective layer 137 covers the first source 135 and the drain 136. The driving circuit layer 13 may also include a planarization layer group 139, which includes a first planarization layer 1391. The first planarization layer 1391 is disposed on the side of the protective layer 137 away from the substrate 11, and the first planarization layer 1391 covers the protective layer 137.

[0080] The driving circuit layer 13 may further include a second source / drain metal layer, which is disposed on the side of the first planarization layer 1391 away from the substrate 11. The second source / drain metal layer may include a second source 138, which is connected to the first source 135. The planarization layer group 139 may further include a second planarization layer 1392, which is disposed on the side of the second source 138 away from the substrate 11. The second planarization layer 1392 covers the second source 138 and the first planarization layer 1391.

[0081] The display panel may further include a pixel defining layer 15 and a light-emitting layer 16. The pixel defining layer 15 is disposed on the side of the first planarization layer 1391 or the second planarization layer 1392 away from the array substrate. The pixel defining layer 15 includes a plurality of pixel defining portions, and a pixel opening 151 is formed between two adjacent pixel defining portions. The light-emitting layer 16 may include a plurality of light-emitting units 162, which are respectively disposed in different pixel openings 151. Each light-emitting unit 162 may include a pixel electrode 161, a light-emitting unit 162, and a common electrode 163. The pixel electrode 161 is located on the surface of the first planarization layer 1391 or the second planarization layer 1392 away from the substrate 11. The light-emitting unit 162 is disposed on the surface of the pixel electrode 161 away from the substrate 11, and the common electrode 163 is disposed on the surface of the light-emitting unit 162 away from the substrate 11. The light-emitting unit 162 can be driven to emit light through the pixel electrode 161 and the common electrode 163 to display an image.

[0082] Pixel electrode 161 is connected to either the first source 135 or the second source 138. A pixel defining layer 15 is provided on the side of pixel electrode 161 away from the substrate 11. When the thin-film transistor includes only the first source 135, pixel electrode 161 is connected to the first source 135, and pixel defining layer 15 covers pixel electrode 161 and the first planarization layer 1391. When the thin-film transistor also includes the second source 138, pixel electrode 161 is connected to the second source 138, and pixel defining layer 15 covers pixel electrode 161 and the second planarization layer 1392.

[0083] The common electrode 163 can serve as the cathode, and the pixel electrode 161 can serve as the anode. Light emission from the light-emitting unit 162 can be driven by applying a signal to the pixel electrode 161; the specific light emission principle will not be detailed here. The light-emitting unit 162 may contain an electroluminescent organic light-emitting material and can be formed using processes such as vapor deposition. For example, the light-emitting unit 162 may include a hole injection layer, a hole transport layer, a light generation layer, an electron transport layer, and an electron injection layer sequentially stacked on the pixel electrode 161. It should be noted that, depending on the emitted color, the light-emitting unit 162 may include a first light-emitting unit 1621, a second light-emitting unit 1622, and a third light-emitting unit 1623.

[0084] Furthermore, the display panel of this utility model may also include an encapsulation layer 17, which is disposed on the side of the light-emitting layer 16 away from the substrate 11, thereby covering the light-emitting layer 16 and preventing water and oxygen corrosion. The encapsulation layer 17 may be a single-layer or multi-layer structure, and the material of the encapsulation layer 17 may include organic or inorganic materials, without special limitation. In this embodiment, the encapsulation layer 17 may include a first inorganic encapsulation layer 171, an organic encapsulation layer 172, and a second inorganic encapsulation layer 173. The first inorganic encapsulation layer 171 is disposed on the side of the light-emitting layer 16 away from the substrate 11, the organic encapsulation layer 172 is disposed on the side of the first inorganic encapsulation layer 171 away from the substrate 11, and the second inorganic encapsulation layer 173 is disposed on the side of the organic encapsulation layer 172 away from the substrate 11.

[0085] The display panel also includes a touch control layer 18, which can be a mutual capacitive touch control layer. The touch control layer 18 includes a first touch control layer 181 and a second touch control layer 182. The first touch control layer 181 is a metal mesh layer (MM), and the second touch control layer 182 is a bridge metal layer (BM). The metal mesh is located in the display area and can be divided into touch driving (Tx) metal mesh and touch sensing (Rx) metal mesh according to the horizontal and vertical directions. One of the touch sensing (Rx) metal mesh and the touch driving (Tx) metal mesh is interconnected, while the other is connected through the bridge metal layer.

[0086] The first tactile control layer 181 is disposed on the side of the substrate 11 away from the encapsulation layer 17, and the second tactile control layer 182 is disposed between the first tactile control layer 181 and the encapsulation layer 17. The tactile control layer 18 may further include a touch blocking layer 183 and a touch isolating layer 184, with the touch blocking layer 183 disposed between the encapsulation layer 17 and the second tactile control layer 182, and the touch isolating layer 184 disposed between the first tactile control layer 181 and the second tactile control layer 182.

[0087] The first tactile control layer 181 may include a plurality of first touch units 1811, which are spaced apart. The orthographic projection of a first touch unit 1811 on the substrate 11 is located between the orthographic projections of two adjacent light-emitting units 162 on the substrate 11. The second tactile control layer 182 may include a plurality of second touch units 1821, whose orthographic projections on the substrate 11 overlap with the orthographic projections of the first touch units 1811 on the substrate 11.

[0088] The display panel may further include a light control layer, which may include a light-shielding layer 19. The light-shielding layer 19 includes multiple light-shielding portions 191, which are located on the side of the first cover portion 205 away from the driving backplate 10. The orthographic projection of the light-shielding portion 191 on the substrate 11 covers the orthographic projection of the first touch unit 1811 on the substrate 11. That is, the orthographic projection of the first touch unit 1811 on the substrate 11 is located within the orthographic projection of the light-shielding portion 191 on the substrate 11, and the area of ​​the orthographic projection of the first touch unit 1811 on the substrate 11 is smaller than the area of ​​the orthographic projection of the light-shielding portion 191 on the substrate 11. A light-transmitting opening 192 is formed between the sides of the light-shielding portions 191 that are close to each other. The light control layer may further include a light filter layer 21, which may include multiple light filter units of different colors, and the multiple filter units are respectively located in different light-transmitting openings 192. The display panel may also include a second cover layer 22 that covers the side of the filter layer 21 away from the drive backplate 10.

[0089] like Figure 4 and Figure 5 As shown, the light-transmitting opening 192 includes a first light-transmitting opening 193, a second light-transmitting opening 194, and a third light-transmitting opening 195. The multiple filter units include a first filter unit 211, a second filter unit 212, and a third filter unit 213. The first filter unit 211 is disposed in the first light-transmitting opening 193, the second filter unit 212 is disposed in the second light-transmitting opening 194, and the third filter unit 213 is disposed in the third light-transmitting opening 195.

[0090] The orthographic projection of the first filter unit 211 on the substrate 11 covers the orthographic projection of the first light-emitting unit 1621 on the substrate 11. The orthographic projection of the second filter unit 212 on the substrate 11 covers the orthographic projection of the second light-emitting unit 1622 on the substrate 11. The orthographic projection of the third filter unit 213 on the substrate 11 covers the orthographic projection of the third light-emitting unit 1623 on the substrate 11. The color of the first light-emitting unit 1621 is the same as the color of the first filter unit 211. The color of the second light-emitting unit 1622 is the same as the color of the second filter unit 212. The color of the third light-emitting unit 1623 is the same as the color of the third filter unit 1.

[0091] The filter layer 21 has m×n groups of light-transmitting openings 192. The m groups of light-transmitting openings 192 extend along a first direction and are arranged along a second direction, while the n groups of light-transmitting openings 192 extend along the second direction and are arranged along the first direction. The light-transmitting openings 192 in the same m group are divided into two rows, which are arranged alternately. One row consists of alternating first light-transmitting openings 193 and third light-transmitting openings 195, while the other row consists of second light-transmitting openings 194. The second light-transmitting openings 194 are arranged along the first direction... Between the first light-transmitting opening 193 and the third light-transmitting opening 195; n sets of light-transmitting openings 192 extend along the second direction and are arranged along the first direction. The same n sets of light-transmitting openings 192 are divided into two columns, and the two columns of light-transmitting openings 192 are arranged alternately. One column of light-transmitting openings 192 consists of alternating first light-transmitting openings 193 and third light-transmitting openings 195, and the other column is a second light-transmitting opening 194. The second light-transmitting opening 194 is located between the first light-transmitting opening 193 and the third light-transmitting opening 195 along the second direction.

[0092] The pixel opening 151 includes a first pixel opening 152, a second pixel opening 153, and a third pixel opening 154. The orthographic projection of the first pixel opening 152 on the driving back plate 10 is located within the orthographic projection of the first light-transmitting opening 193 on the substrate 11. The orthographic projection of the second pixel opening 153 on the driving back plate 10 is located within the orthographic projection of the second light-transmitting opening 194 on the driving back plate 10. The orthographic projection of the third pixel opening 154 on the driving back plate 10 is located within the orthographic projection of the third light-transmitting opening 1923 on the driving back plate 10.

[0093] The orthographic projection of the first light-transmitting opening 193 on the drive back plate 10 is located within the orthographic projection of the first filter unit 211 on the drive back plate 10; the orthographic projection of the second light-transmitting opening 194 on the drive back plate 10 is located within the orthographic projection of the second filter unit 212 on the drive back plate 10; and the orthographic projection of the third light-transmitting opening 195 on the drive back plate 10 is located within the orthographic projection of the third filter unit 213 on the drive back plate 10.

[0094] like Figure 5 and Figure 6 As shown, the light-shielding layer 19 has different types of light-transmitting openings 192. The edge of each light-transmitting opening 192 has a first light-transmitting segment and a second light-transmitting segment. The distance between the first light-transmitting segment and the center of the light-transmitting opening 192 is the first light-transmitting distance, and the distance between the second light-transmitting segment and the center of the light-transmitting opening 192 is the second light-transmitting distance. The first light-transmitting distance is less than the second light-transmitting distance, meaning that the first light-transmitting segment is recessed towards the center of the light-transmitting opening 192 relative to the second light-transmitting segment. The difference between the second light-transmitting distance and the first light-transmitting distance is the first distance difference, which is 2-5 μm.

[0095] In this embodiment, the magnitude of the first light-transmitting distance varies along the extension direction of the first light-transmitting segment. Both the first and second light-transmitting segments are arc-shaped segments, with the curvature of the first and second light-transmitting segments differing. The first light-transmitting segment can be a semi-circular or elliptical arc with a recessed center in the light-transmitting opening 192. Alternatively, the first light-transmitting segment can be a broken line segment, which can be a sharp angle recessed towards the center of the light-transmitting opening 192.

[0096] The line connecting the midpoint of the first light-transmitting segment and the center of the light-transmitting opening 192 is the light-transmitting rotation line. The angle between different light-transmitting rotation lines and the first direction is the light-transmitting rotation angle. In the same type of light-transmitting opening 192, at least some of the first light-transmitting segments have different light-transmitting rotation angles. By controlling the light-transmitting rotation angle, the position of the first light-transmitting segment at the edge of the light-transmitting opening 192 can be controlled to be different, thereby changing the amount of light transmitted at different positions on the edge of different light-transmitting openings 192. This causes the reflected light from the ambient light to produce a destructive interference effect when passing through different light-transmitting openings 192, reducing or eliminating the possibility of color separation in visual effects. To further reduce the possibility of color separation in visual effects, all first light-transmitting segments can be set to be different, and the amount of light transmitted at different positions of all light-transmitting openings 192 can be adjusted so that all light-transmitting openings 192 produce a destructive interference effect.

[0097] For the same type of light-transmitting opening 192, two light-transmitting rotation angles θ satisfy: θ2=θ1+p; where the smaller light-transmitting rotation angle is θ1, and the larger light-transmitting rotation angle is θ2, 0<θ1<θ2≤360, and the interval between two adjacent light-transmitting rotation angles is p, 0<p≤360; different sizes of light-transmitting rotation angles are randomly distributed in different light-transmitting openings 192.

[0098] The light-transmitting opening 192 includes a first light-transmitting opening 193, a second light-transmitting opening 194, and a third light-transmitting opening 195. A first filter unit 211 is disposed within the first light-transmitting opening 193, a second filter unit 212 is disposed within the second light-transmitting opening 194, and a third filter unit 213 is disposed within the third light-transmitting opening 195. The first light-transmitting segment includes a first sub-light-transmitting segment 1931, a third sub-light-transmitting segment 1941, and a fifth sub-light-transmitting segment 1951. The second light-transmitting segment includes a second sub-light-transmitting segment 1932, a fourth sub-light-transmitting segment 1942, and a sixth sub-light-transmitting segment 1952. The first light-transmitting opening 193 includes a first sub-light-transmitting segment 1931 and a second sub-light-transmitting segment 1932. The second light-transmitting opening 194 includes a third sub-light-transmitting segment 1941 and a fourth sub-light-transmitting segment 1942. The third light-transmitting opening 195 includes a fifth sub-light-transmitting segment 1951 and a sixth sub-light-transmitting segment 1952.

[0099] The distance between the center of the first sub-transmitting segment 1931 and the center of the first transmitting opening 193 is the first sub-transmitting distance. The distance between the center of the second sub-transmitting segment 1932 and the center of the first transmitting opening 193 is the second sub-transmitting distance. The first sub-transmitting distance is less than the second sub-transmitting distance. The line connecting the midpoint of the first sub-transmitting segment 1931 and the center of the first transmitting opening 193 is the first transmitting rotation line OB. The angle between different first transmitting rotation lines OB and the first direction OA is the first transmitting rotation angle. Among the multiple first transmitting openings 193, at least some of the first sub-transmitting segments 1931 have different first transmitting rotation angles.

[0100] The distance between the center of the third sub-transmitting segment 1941 and the center of the second transmitting opening 194 is the third sub-transmitting distance. The distance between the center of the fourth sub-transmitting segment 1942 and the center of the second transmitting opening 194 is the fourth sub-transmitting distance. The third sub-transmitting distance is less than the fourth sub-transmitting distance. The line connecting the midpoint of the third sub-transmitting segment 1941 and the center of the second transmitting opening 194 is the second transmitting rotation line OC. The angle between different second transmitting rotation lines OC and the first direction OA is the second transmitting rotation angle. Among the multiple second transmitting openings 194, at least some of the third sub-transmitting segments 1941 have different second transmitting rotation angles.

[0101] The distance between the center of the fifth sub-transmitting segment 1951 and the center of the third transmitting opening 195 is the fifth sub-transmitting distance. The distance between the center of the sixth sub-transmitting segment 1952 and the center of the third transmitting opening 195 is the sixth sub-transmitting distance. The fifth sub-transmitting distance is less than the sixth sub-transmitting distance. The line connecting the midpoint of the fifth sub-transmitting segment 1951 and the center of the third transmitting opening 195 is the third transmitting rotation line OD. The angle between different third transmitting rotation lines OD and the first direction OA is the third transmitting rotation angle. Among the multiple third transmitting openings 195, at least some of the fifth sub-transmitting segments 1951 have different third transmitting rotation angles.

[0102] Among the multiple first light-transmitting openings 193, the two first light-transmitting rotation angles θa satisfy: θa2=θa1+p1; where the smaller first light-transmitting rotation angle is θa1, and the larger first light-transmitting rotation angle is θa2, 0<θa1<θa2≤360, and the interval between two adjacent first light-transmitting rotation angles is p1, 0<p1≤360; the first light-transmitting rotation angles of different sizes are randomly distributed in different first light-transmitting openings 193.

[0103] Among the multiple second light-transmitting openings 194, the two second light-transmitting rotation angles θb satisfy: θb2=θb1+p2; where the smaller second light-transmitting rotation angle is θb1, and the larger second light-transmitting rotation angle is θb2, 0<θb1<θb2≤360, and the interval between two adjacent second light-transmitting rotation angles is p2, 0<p2≤360; the second light-transmitting rotation angles of different sizes are randomly distributed in different second light-transmitting openings 194.

[0104] Among multiple third light-transmitting openings 195, two third light-transmitting rotation angles θc satisfy: θc2=θc1+p3; where the smaller third light-transmitting rotation angle is θc1, and the larger third light-transmitting rotation angle is θc2, 0<θc1<θc2≤360, and the interval between two adjacent third light-transmitting rotation angles is p3, 0<p3≤360; different sizes of third light-transmitting rotation angles are randomly distributed in different third light-transmitting openings 195.

[0105] When the light-shielding layer 19 has 4×4 sets of light-transmitting openings 192, the first light-transmitting rotation angle θa of the first light-transmitting opening 193 can be set according to the rules in Table 1.

[0106] Table 1 shows the setting rules for the first light transmission rotation angle θa of the first light transmission opening 193 when the light-shielding layer 19 has 4×4 groups of light transmission openings 192.

[0107]

[0108] Take any two adjacent first light-transmitting rotation angles θa. For example, the first light-transmitting rotation angle θa1 of the first light-transmitting opening 193 in the 2nd row × 3rd column is 22.5°, and the first light-transmitting rotation angle θa2 of the first light-transmitting opening 193 in the 3rd row × 2nd column is 33.75°. Therefore, p1 is 11.25°.

[0109] When the light-shielding layer 19 has 4×4 sets of light-transmitting openings 192, the second light-transmitting rotation angle θb of the second light-transmitting opening 194 can be set according to the rules in Table 2.

[0110] Table 2 shows the setting rules for the second light transmission rotation angle θb of the second light transmission opening 194 when the light-shielding layer 19 has 4×4 groups of light transmission openings 1920.

[0111]

[0112] Take any two adjacent second light-transmitting rotation angles θb. For example, the second light-transmitting rotation angle θb1 of the second light-transmitting opening 194 in the first row × first column is 202.5°, and the second light-transmitting rotation angle θb2 of the second light-transmitting opening 194 in the fourth row × fourth column is 213.75°. Therefore, p2 is 11.25°.

[0113] When the light-shielding layer 19 has 4×4 sets of light-transmitting openings 192, the third light-transmitting rotation angle θc of the third light-transmitting opening 195 can be set according to the rules in Table 3.

[0114] Table 3 shows the setting rules for the third light transmission rotation angle θc of the third light transmission opening 195 when the light-shielding layer 19 has 4×4 groups of light transmission openings 192.

[0115]

[0116] Take any two adjacent third light-transmitting rotation angles θc. For example, the third light-transmitting rotation angle θc1 of the third light-transmitting opening 195 in the 1st row × 4th column is 213.75°, and the third light-transmitting rotation angle θc2 of the third light-transmitting opening 195 in the 4th row × 1st column is 202.5°. Therefore, p3 is 11.25°.

[0117] The display panel has multiple pixel units, each pixel unit including a first sub-pixel, a second sub-pixel, and a third sub-pixel with different colors. The first light-transmitting opening 193, the second light-transmitting opening 194, and the third light-transmitting opening 195 corresponding to the same pixel unit have different light-transmitting rotation angles. In addition to the interference cancellation effect between multiple first light-transmitting openings 193, multiple second light-transmitting openings 194, and multiple second light-transmitting openings 195, the first light-transmitting opening 193, the second light-transmitting opening 194, and the third light-transmitting opening 195 corresponding to the same pixel unit can also produce interference cancellation effect, further reducing the possibility of color separation phenomenon in visual effect.

[0118] It is also possible to set any first light transmission rotation angle, any second light transmission rotation angle, and any third light transmission rotation angle to be different from each other, so that interference cancellation can occur between any first light transmission opening 193, any second light transmission opening 194, and any third light transmission opening 195, further enhancing the effect of interference cancellation of reflected ambient light at light transmission opening 192.

[0119] like Figures 7 to 9 As shown, the edge of the pixel opening 151 has a first pixel segment and a second pixel segment. The distance between the first pixel segment and the center of the pixel opening 151 is the first pixel distance, and the distance between the second pixel segment and the center of the pixel opening 151 is the second pixel distance. The second pixel distance is less than the first pixel distance, that is, the first pixel segment is recessed towards the center of the pixel opening 151 relative to the second pixel segment.

[0120] In this embodiment, the distance between the first pixels varies along the extension direction of the first pixel segment. Both the first and second pixel segments are arc-shaped segments, with the curvature of the first pixel segment differing from that of the second pixel segment. The first pixel segment can be a semi-circular or elliptical arc with a recessed center in the pixel opening 151. Alternatively, the first pixel segment can be a broken line segment, which can be a sharp angle concave towards the center of the pixel opening 151. When the first light-transmitting segment, the first pixel segment, the second light-transmitting segment, and the second pixel segment are all arc-shaped, the curvature of the first light-transmitting segment is the same as that of the first pixel segment, and the curvature of the second light-transmitting segment is the same as that of the second pixel segment, thus avoiding any impact on the light emission of the light-emitting unit 162.

[0121] The difference between the second light transmission distance and the first light transmission distance is the first distance difference. The difference between the second pixel distance and the first pixel distance is the second distance difference. The second distance difference is equal to the first distance difference. Both the first distance difference and the second distance difference are 2-5μm.

[0122] The line connecting the midpoint of the first pixel segment and the center of the pixel opening 151 is the pixel rotation line. The angle between different pixel rotation lines and the first direction OA is the pixel rotation angle. In the same pixel opening 151, at least some of the first pixel segments have different pixel rotation angles. By controlling the pixel rotation angle, the position of the first pixel segment at the edge of the pixel opening 151 can be controlled to be different, thereby changing the amount of light transmitted at different positions on the edge of different pixel openings 151. This causes the reflected light from the ambient light to produce a destructive interference effect when passing through different pixel openings 151, reducing or eliminating the possibility of color separation in visual effect. To further reduce the possibility of color separation in visual effect, all first pixel segments can be set to be different, and the amount of light transmitted at different positions of all pixel openings 151 can be adjusted so that all pixel openings 151 produce a destructive interference effect.

[0123] Pixel opening 151 includes a first pixel opening 152, a second pixel opening 153, and a third pixel opening 154. A first light-emitting unit 1621 is disposed within the first pixel opening 152, a second light-emitting unit 1622 is disposed within the second pixel opening 153, and a third light-emitting unit 1623 is disposed within the third pixel opening 154. A first pixel segment includes a first sub-pixel segment 1521, a third sub-pixel segment 1531, and a fifth sub-pixel segment 1541. A second pixel segment includes a second sub-pixel segment 1522, a fourth sub-pixel segment 1532, and a sixth sub-pixel segment 1542. The first pixel opening 152 includes the first sub-pixel segment 1521 and the second sub-pixel segment 1522. The second pixel opening 153 includes the third sub-pixel segment 1531 and the fourth sub-pixel segment 1532. The third pixel opening 154 includes the fifth sub-pixel segment 1541 and the sixth sub-pixel segment 1542.

[0124] The distance between the center of the first sub-pixel segment 1521 and the center of the first pixel opening 152 is the first sub-pixel distance, and the distance between the center of the second sub-pixel segment 1522 and the center of the first pixel opening 152 is the second sub-pixel distance. The first sub-pixel distance is less than the second sub-pixel distance. The line connecting the midpoint of the first sub-pixel segment 1521 and the center of the first pixel opening 152 is the first pixel rotation line OE. The angle between different first pixel rotation lines OE and the first direction OA is the first pixel rotation angle. Among the multiple first pixel openings 152, at least some of the first sub-pixel segments 1521 have different first pixel rotation angles.

[0125] The distance between the center of the third sub-pixel segment 1531 and the center of the second pixel opening 153 is the third sub-pixel distance, and the distance between the center of the fourth sub-pixel segment 1532 and the center of the second pixel opening 153 is the fourth sub-pixel distance. The third sub-pixel distance is less than the fourth sub-pixel distance. The line connecting the midpoint of the third sub-pixel segment 1531 and the center of the second pixel opening 153 is the second pixel rotation line OF. The angle between different second pixel rotation lines OF and the first direction OA is the second pixel rotation angle. Among the multiple second pixel openings 153, at least some of the third sub-pixel segments 1531 have different second pixel rotation angles.

[0126] The distance between the center of the fifth sub-pixel segment 1541 and the center of the third pixel opening 154 is the fifth sub-pixel distance. The distance between the center of the sixth sub-pixel segment 1542 and the center of the third pixel opening 154 is the sixth sub-pixel distance. The fifth sub-pixel distance is less than the sixth sub-pixel distance. The line connecting the midpoint of the fifth sub-pixel segment 1541 and the center of the third pixel opening 154 is the third pixel rotation line OG. The angle between different third pixel rotation lines OG and the first direction OA is the third pixel rotation angle. Among the multiple third pixel openings 154, at least some of the fifth sub-pixel segments 1541 have different third pixel rotation angles.

[0127] like Figure 7 and Figure 8 As shown, when the orthographic projection of pixel opening 151 on the driving backplate 10 is the same as the orthographic projection of light-transmitting opening 192 on the driving backplate 10, the pixel rotation line and the light-transmitting rotation line are on the same straight line. Therefore, the first light-transmitting rotation angle of the first light-transmitting opening 193 is the same as the first pixel rotation angle of the first pixel opening 152 (see Table 1). The second light-transmitting rotation angle of the second light-transmitting opening 194 is the same as the second pixel rotation angle of the second pixel opening 153 (see Table 2). The third light-transmitting rotation angle of the third light-transmitting opening 195 is the same as the third pixel rotation angle of the third pixel opening 154 (see Table 3). Figure 9 As shown, the pixel rotation line and the light transmission rotation line can also be set to be on different straight lines. Specifically, the angle β between the pixel rotation line and the light transmission rotation line can be 5-90 degrees.

[0128] like Figure 10 and Figure 11 As shown, with Figure 5 and Figure 6 The difference lies in that the first light transmission distance is greater than the second light transmission distance, meaning that the first light transmission segment protrudes away from the light transmission opening 192, and the shape of the first light transmission segment can be any shape among triangles, circles, and ellipses. For example... Figure 12 and Figure 13 As shown, in Figure 10 and Figure 11 Based on this, the first pixel distance can be set to be greater than the second pixel distance, that is, the first pixel segment can be set to protrude in a direction away from the pixel opening 151. The shape of the first pixel segment can be any shape among triangle, circle, and ellipse, and the pixel rotation line and the light transmission rotation line are located on the same straight line. For example Figure 14 As shown, the pixel rotation line and the light transmission rotation line can also be set to be on different straight lines. Specifically, the angle between the pixel rotation line and the light transmission rotation line can be 5-90 degrees.

[0129] In the above embodiments, the curvature of the first light-transmitting segment is typically smaller than that of the second light-transmitting segment, and the curvature of the first pixel segment is smaller than that of the second pixel segment. In other embodiments, the curvature of the first light-transmitting segment can be set to be greater than that of the second light-transmitting segment, and the curvature of the first light-transmitting segment can be increased indefinitely; in extreme cases, the first light-transmitting segment can also be set as a straight line. Similarly, the curvature of the first pixel segment can be set to be greater than that of the second pixel segment, and the curvature of the first pixel segment can be increased indefinitely; in extreme cases, the first pixel segment can also be set as a straight line.

[0130] like Figure 15 As shown, the magnitude of the first light-transmitting distance remains unchanged along the extension direction of the first light-transmitting segment. The first light-transmitting segment includes a straight light-transmitting segment 1921 and an arc-shaped light-transmitting segment 1922. Both the arc-shaped light-transmitting segment 1922 and the second light-transmitting segment are arc-shaped segments. The curvature of the arc-shaped light-transmitting segment 1922 is the same as that of the second light-transmitting segment. The straight light-transmitting segment 1921 is connected to both ends of the arc-shaped light-transmitting segment 1922 and both ends of the second light-transmitting segment. Similarly, the magnitude of the first pixel distance remains unchanged along the extension direction of the first pixel segment. The first pixel segment includes a straight pixel segment 1511 and an arc-shaped pixel segment 1512. Both the arc-shaped pixel segment 1512 and the second pixel segment are arc-shaped segments. The curvature of the arc-shaped pixel segment 1512 is the same as that of the second pixel segment. The straight pixel segment 1511 is connected to both ends of the arc-shaped pixel segment 1512 and both ends of the second pixel segment.

[0131] like Figure 16As shown, the first light-transmitting distance can also be set to be greater than the second light-transmitting distance, that is, the first light-transmitting segment can be set to protrude in a direction away from the light-transmitting opening 192. Alternatively, the first pixel distance can be set to be less than the second pixel distance, that is, the first pixel segment can be set to be recessed in a direction away from the pixel opening 151. For example... Figure 17 As shown, the first light transmission distance can be set to be less than the second light transmission distance, that is, the first light transmission segment can be set to be concave in the direction away from the light transmission opening 192, and the first pixel distance can be set to be greater than the second pixel distance, that is, the first pixel segment can be set to be convex in the direction away from the pixel opening 151. This changes the amount of light transmitted at different positions on the edges of different light transmission openings 192 and different positions on the edges of different pixel openings 151, so that the reflected light from the ambient light produces an interference cancellation effect when passing through different light transmission openings 192 and pixel openings 151, thereby reducing or eliminating the color separation phenomenon in the visual effect.

[0132] like Figure 18 As shown, the light control layer may further include a first cover layer 20, which is disposed between the first touch layer and the light shielding layer 19. The first cover layer 20 includes a plurality of first cover portions 205, which are disposed on the side of the first touch unit 1811 away from the substrate 11. The first cover portions 205 cover the first touch unit 1811. The display panel can use the first cover portions 205 to insulate the first touch unit 1811, thereby reducing the thickness of the display panel.

[0133] A dimming opening 201 is formed between two adjacent first covering portions 205. The orthographic projection of the dimming opening 201 on the substrate 11 is located between the orthographic projection of the light-transmitting opening 192 on the substrate 11 and the orthographic projection of the pixel opening 151 on the substrate 11. A first filter unit 211, a second filter unit 212, and a third filter unit 213 are respectively disposed within the dimming opening 201 formed by the two adjacent first covering portions 205.

[0134] The first cover 205 can be made of a low-refractive-index resin material with a refractive index of 1.45-1.5. The refractive indices of the first filter unit 211, the second filter unit 212, and the third filter unit 213 are typically 1.55-1.85. The refractive indices of the three color filter units are all higher than those of the first cover 205. The slope angle of the side of the first cover 205 is less than 90 degrees. Therefore, reflected light from the ambient light at an oblique angle can undergo total internal reflection on the side of the first cover 205, deflecting it to the direction of the normal viewing angle, thus improving the light extraction efficiency at the normal viewing angle. The first cover 205 is trapezoidal in shape, with conventionally sloped sides, making the slope angle easier to control.

[0135] like Figure 19As shown, the dimming opening 201 includes a first dimming opening 202, a second dimming opening 203, and a third dimming opening 204. The orthographic projection of the first dimming opening 202 on the driving backplate 10 is located between the orthographic projections of the first light-transmitting opening 193 and the first pixel opening 152 on the driving backplate 10. The orthographic projection of the second dimming opening 203 on the driving backplate 10 is located between the orthographic projection of the second light-transmitting opening 194 and the first pixel opening 152 on the substrate 11. The orthographic projection of the third dimming opening 204 on the driving backplate 10 is located between the orthographic projection of the third light-transmitting opening 195 and the third pixel opening 154 on the substrate 11.

[0136] The edge of the dimming opening 201 has a first dimming segment and a second dimming segment. The distance between the first dimming segment and the center of the dimming opening 201 is the first dimming distance, and the distance between the second dimming segment and the center of the dimming opening 201 is the second dimming distance. The second dimming distance is not equal to the first dimming distance. The line connecting the midpoint of the first dimming segment and the center of the dimming opening 201 is the dimming rotation line. The angle between different dimming rotation lines and the first direction OA is the dimming rotation angle. In the same dimming opening 201, at least some of the first dimming segments have different dimming rotation angles. The dimming rotation line, the pixel rotation line, and the light transmission rotation line can be set on the same straight line.

[0137] The dimming opening 201 includes a first dimming opening 202, a second dimming opening 203, and a third dimming opening 204. The first dimming segment includes a first sub-dimming segment 2021, a third sub-dimming segment 2031, and a fifth sub-dimming segment 2041. The second dimming segment includes a second sub-dimming segment 2022, a fourth sub-dimming segment 2032, and a sixth sub-dimming segment 2042. The first dimming opening 202 includes a first sub-dimming segment 2021 and a second sub-dimming segment 2022. The second dimming opening 203 includes a third sub-dimming segment 2031 and a fourth sub-dimming segment 2032. The third dimming opening 204 includes a fifth sub-dimming segment 2041 and a sixth sub-dimming segment 2042.

[0138] The distance between the center of the first sub-dimming segment 2021 and the center of the first dimming opening 202 is the first sub-dimming distance, and the distance between the center of the second sub-dimming segment 2022 and the center of the first dimming opening 202 is the second sub-dimming distance. The first sub-dimming distance is less than the second sub-dimming distance. The line connecting the midpoint of the first sub-dimming segment 2021 and the center of the first dimming opening 202 is the first dimming rotation line OP. The angle between different first dimming rotation lines OP and the first direction OA is the first dimming rotation angle. Among the multiple first dimming openings 202, at least some of the first sub-dimming segments 2021 have different first dimming rotation angles.

[0139] The distance between the center of the third sub-dimming segment 2031 and the center of the second dimming opening 203 is the third sub-dimming distance. The distance between the center of the fourth sub-dimming segment 2032 and the center of the second dimming opening 203 is the fourth sub-dimming distance. The third sub-dimming distance is less than the fourth sub-dimming distance. The line connecting the midpoint of the third sub-dimming segment 2031 and the center of the second dimming opening 203 is the second dimming rotation line OQ. The angle between different second dimming rotation lines OQ and the first direction OA is the second dimming rotation angle. Among the multiple second dimming openings 203, at least some of the third sub-dimming segments 2031 have different second dimming rotation angles.

[0140] The distance between the center of the fifth sub-dimming segment 2041 and the center of the third dimming opening 204 is the fifth sub-dimming distance, and the distance between the center of the sixth sub-dimming segment 2042 and the center of the third dimming opening 204 is the sixth sub-dimming distance. The fifth sub-dimming distance is less than the sixth sub-dimming distance. The line connecting the midpoint of the fifth sub-dimming segment 2041 and the center of the third dimming opening 204 is the third dimming rotation line OR. The angle between different third dimming rotation lines OR and the first direction OA is the third dimming rotation angle. Among the multiple third dimming openings 204, at least some of the fifth sub-dimming segments 2041 have different third dimming rotation angles.

[0141] like Figure 20 As shown, the dimming rotation line, pixel rotation line, and light transmission rotation line can also be located on different straight lines, that is, the first pixel rotation angle, the first dimming rotation angle, and the first light transmission rotation angle are all different; the second pixel rotation angle, the second dimming rotation angle, and the second light transmission rotation angle are all different; and the third pixel rotation angle, the third dimming rotation angle, and the third light transmission rotation angle are all different. In other embodiments, the first pixel rotation angle, the first dimming rotation angle, and the first light transmission rotation angle can also be the same; the second pixel rotation angle, the second dimming rotation angle, and the second light transmission rotation angle are all different; and the third pixel rotation angle, the third dimming rotation angle, and the third light transmission rotation angle are all different. Further explanation is not provided here.

[0142] In other embodiments, the dimming rotation line and the pixel rotation line may be positioned on the same straight line, and the light transmission rotation line may be offset at a certain angle relative to the dimming rotation line and the pixel rotation line. Alternatively, the dimming rotation line and the light transmission rotation line may be positioned on the same straight line, and the pixel rotation line may be offset at a certain angle relative to the dimming rotation line and the light transmission rotation line.

[0143] It should be noted that the first direction is the x-direction shown in the figure, and the second direction is the y-direction shown in the figure.

[0144] By controlling the different rotation angles of light transmission, the position of the first light transmission segment at the edge of the light transmission opening 192 can be controlled to be different, thereby changing the amount of light transmitted at different positions at the edge of different light transmission openings 192. When the reflected light from the ambient light diffracts at the edge of the light transmission opening 192, the diffracted light waves from different light transmission openings 192 will interfere and cancel each other out, the diffraction rings become faint, and the boundary between two adjacent diffraction rings becomes blurred, thus improving the color separation phenomenon.

[0145] Combination Figure 21 Analysis shows that curve S1 is... Figure 10 When the distance between the edge of the light-transmitting opening 192 and its center remains essentially constant, and the distance between the edge of the pixel opening 151 and its center also remains essentially constant, that is... Figure 1 The curve showing the relationship between light intensity and distance on the display panel; curve S2 is Figure 10 The curve showing the relationship between light intensity and distance on the display panel, curve S3 is... Figure 12 The curve showing the relationship between light intensity and distance on the display panel. At locations with the same radius, the light intensity corresponding to curve S2 is significantly greater than that corresponding to curve S1, which also illustrates... Figure 10 The display panel in the middle is more Figure 1 The diffracted light waves from the central display panel are more concentrated and the diffraction is less, therefore Figure 10 The display panel in the middle is more Figure 1 The color separation phenomenon is weaker in the display panel. The light intensity corresponding to curve S3 is significantly greater than that corresponding to curve S2, which also indicates... Figure 12 The display panel in the middle is more Figure 10 The diffracted light waves from the central display panel are more concentrated and the diffraction is less, therefore Figure 12 The display panel in the middle is more Figure 10 The color separation phenomenon is weaker in the display panel.

The specific structure and beneficial effects of the display panel have already been described in detail above, and therefore will not be repeated here.
