Description

Technical Field

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

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

[0003] The reflected light of ambient light undergoes diffraction at the edge of the light-transmitting opening. Since the wavelengths of lights of different colors are different, lights of different colors will generate different diffracted light waves, and the diffracted light waves of different light-transmitting openings will interfere and enhance to form diffracted light rings of different colors, resulting in color separation in the visual effect.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present invention, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0069] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale.

[0070] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the drawings. It can be understood that if the device of the icon is flipped so that it is upside down, the component described as "upper" will become the component described as "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0071] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and are not a limitation on the quantity of their objects.

[0072] The FMLOC (Flexible multi-Layer On Cell) design is currently the mainstream in the field of OLED touch displays. The FMLOC design means that a metal electrode layer is fabricated on the encapsulation layer 17 of the display substrate, and the surface of the metal electrode layer has a significant reflection of ambient light. In order to improve the contrast of the display panel and reduce the reflected light, a polarizer is usually disposed 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 will cause the light intensity of the display panel to attenuate and will result in a relatively large thickness of the display panel.

[0073] As Figure 1 shown, in order to reduce the thickness of the display panel and improve the light extraction gain, a color film layer is disposed on the light-emitting side of the light-emitting layer 16 to replace the polarizer. The color film layer is still disposed on the side of the encapsulation layer 17 away from the driving backplane 10. The color film layer includes a light-shielding layer 192 and a light-filtering layer 195. Most of the ambient light is absorbed by the light-shielding layer 192, and there is no light intensity attenuation in the light-emitting area of the light-emitting layer 16. The emitted light is directly emitted from the light-filtering layer 195, thereby improving the light extraction gain of the display panel. However, this will cause the emitted light rays with a relatively large oblique angle of the light-emitting unit 162 to directly enter the light-shielding layer 192, resulting in a low utilization rate of the emitted light rays and a relatively large power consumption of the display panel.

[0074] As Figure 2As shown in the figure, in order to improve the light extraction efficiency of the display panel from the front view angle, a first covering layer 191 is provided on the side of the touch electrode layer away from the driving backplane 10. The first covering layer 191 includes a plurality of first covering portions 1911. The touch electrode layer includes a plurality of touch units. The first covering portion 1911 is disposed on the side of the first touch unit 1811 away from the driving backplane 10. The first covering portion 1911 covers the first touch unit 1811, and a dimming opening 1912 is formed between the sides of the first covering portions 1911 that are close to each other. A light-shielding layer 192 is provided on the side of the first covering layer 191 away from the driving backplane 10. The light-shielding layer 192 includes a plurality of light-shielding portions 1924. A light-transmitting opening 1920 is formed between the sides of the light-shielding portions 1924 that are close to each other. Different-color first light-filtering portions 193, second light-filtering portions 1941, and third light-filtering portions 1942 are provided in each dimming opening 1912. The first light-filtering portions 193, second light-filtering portions 1941, and third light-filtering portions 1942 cover the side surfaces of the first covering portions 1911 and extend to the side of the first covering portions 1911 away from the substrate 11.

[0075] Because the width and thickness of the first touch unit 1811 are small, the side surface of the first covering portion 1911 is an inclined surface. The refractive indices of the first light-filtering portion 193, the second light-filtering portion 1941, and the third light-filtering portion 1942 are greater than the refractive index of the first covering portion 1911. Therefore, the light rays emitted from the inclined view angle of the light-emitting unit 162 can undergo total internal reflection at the interface between the side surface of the first covering portion 1911 and the first light-filtering portion 193, the second light-filtering portion 1941, and the third light-filtering portion 1942, deflecting the light rays emitted from the inclined view angle to the front view angle direction for emission, improving the light extraction efficiency of the display panel from the front view angle. Therefore, there is no need to provide a polarizing plate, reducing the thickness of the display panel, which is beneficial to the thinning of the display panel.

[0076] However, whether it is Figure 1 or Figure 2 in the display panel, the reflected light of the ambient light will diffract at the edge of the light-transmitting opening 1920. Since the wavelengths of different-color lights are different, different-color lights will generate different diffracted light waves, and the diffracted light waves of different light-transmitting openings 1920 will interfere and enhance to form diffracted light rings of different colors, resulting in color separation phenomenon in the visual effect. As Figure 3 shown, when the same-color light diffracts at the edge of the light-transmitting opening 1920, a plurality of diffracted light rings that gradually spread outwards will be formed, and there are relatively clear boundaries between the diffracted light rings.

[0077] Based on this, an embodiment of the present invention provides a display panel. As Figures 4 to 33As shown in the figure, the display panel includes a driving backplane 10, a light-shielding layer 192, and a light-filtering layer 195. The light-shielding layer 192 is disposed on one side of the driving backplane 10, and different types of light-transmitting openings 1920 are provided on the light-shielding layer 192. The light-filtering layer 195 includes a first light-filtering portion 193 and other light-filtering portions 194 of different colors. The first light-filtering portion 193 and other light-filtering portions 194 of different colors are disposed in different light-transmitting openings 1920. The first light-filtering portion 193 is disposed on the side of the light-shielding layer 192 away from the driving backplane 10. Different types of overlapping openings 1930 are provided on the first light-filtering portion 193. The orthographic projections of the overlapping openings 1930 on the driving backplane 10 are respectively located within the orthographic projections of the corresponding light-transmitting openings 1920 on the driving backplane 10. Other light-filtering portions 194 of different colors are respectively disposed in different types of overlapping openings 1930, and the colors of the other light-filtering portions 194 are different from the color of the first light-filtering portion 193. At least one type of overlapping opening 1930 has an overlapping contour line 196 and a non-overlapping contour line 197. The distance between the overlapping contour line 196 and the center of the overlapping opening 1930 is less than the distance between the non-overlapping contour line 197 and the center of the overlapping opening 1930. The first light-filtering portion 193 overlaps with adjacent other light-filtering portions 194 of different colors. The portion of the first light-filtering portion 193 located between the edge of the overlapping contour line 196 and the edge of the corresponding overlapping opening 1930 forms an overlapping portion 1935. The shortest connecting line between the edge of the overlapping contour line 196 and the center of the overlapping opening 1930 is a rotation line, and the angle between different rotation lines and the first direction is a rotation angle. In the same type of overlapping opening 1930, at least some of the rotation angles of the overlapping contour lines 196 are different.

[0078] At least one type of overlapping opening 1930 has an overlapping contour line 196 and a non-overlapping contour line 197. The distance between the overlapping contour line 196 and the center of the overlapping opening 1930 is less than the distance between the non-overlapping contour line 197 and the center of the overlapping opening 1930. The first light-filtering portion 193 overlaps with adjacent other light-filtering portions 194 of different colors. The portion of the first light-filtering portion 193 located between the edge of the overlapping contour line 196 and the edge of the corresponding overlapping opening 1930 forms an overlapping portion 1935. The shortest connecting line between the edge of the overlapping contour line 196 and the center of the overlapping opening 1930 is a rotation line, and the angle between different rotation lines and the first direction is a rotation angle. In the same type of overlapping opening 1930, at least some of the rotation angles of the overlapping contour lines 196 are different. By controlling the different rotation angles of the overlapping contour line 196, the position of the overlapping portion 1935 at the edge of the light-transmitting opening 1920 can be controlled to be different, thereby changing the light-transmitting amount at different positions at the edge of different light-transmitting openings 1920, so that the reflected light of the ambient light produces an interference cancellation effect when passing through different light-transmitting openings 1920, weakening or eliminating the color separation phenomenon in the visual effect.

[0079] The display panel involved in the embodiment of the present invention will be described in detail below with reference to specific embodiments.

[0080] As Figures 4 to 6 shown, the display panel generally may include a substrate substrate 11, a driving circuit layer 13. The driving circuit layer 13 is disposed on one side of the substrate substrate 11. The display panel may further include a buffer layer 12, and the buffer layer 12 is disposed between the substrate substrate 11 and the driving circuit layer 13.

[0081] The substrate substrate 11 may be a substrate substrate 11 made of inorganic materials or an organic material substrate 11.

[0086] The thin film transistor can further include an interlayer dielectric layer 134. The interlayer dielectric layer 134 is disposed on the side of the second gate electrode 1332 away from the substrate 11. The interlayer dielectric layer 134 can cover the second gate electrode 1332 and the second gate insulating layer 1322. The first source-drain metal layer is disposed on the surface of the interlayer dielectric layer 134 away from the substrate 11, and the first source-drain metal layer can include a first source electrode 135 and a drain electrode 136. The first source electrode 135 and the drain electrode 136 are connected to the first active layer 131. For example, the first source electrode 135 and the drain electrode 136 are respectively connected to two doped regions of the corresponding first active layer 131 through vias. A protective layer 137 can also be disposed on the side of the first source electrode 135 away from the substrate 11. The protective layer 137 covers the first source electrode 135 and the drain electrode 136. The driving circuit layer 13 can further include a planarization layer group 139. The planarization layer group 139 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. The first planarization layer 1391 covers the protective layer 137.

[0087] The driving circuit layer 13 can further include a second source-drain metal layer. The second source-drain metal layer is disposed on the side of the first planarization layer 1391 away from the substrate 11. The second source-drain metal layer can include a second source electrode 138. The second source electrode 138 is connected to the first source electrode 135. The planarization layer group 139 can further include a second planarization layer 1392. The second planarization layer 1392 is disposed on the side of the second source electrode 138 away from the substrate 11. The second planarization layer 1392 covers the second source electrode 138 and the first planarization layer 1391.

[0088] The display panel may further include a pixel defining layer 15 and a light-emitting layer 16.

The light-emitting layer 16 may include a plurality of light-emitting units 162, and the plurality of light-emitting units 162 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 substrate 11. The light-emitting unit 162 is disposed on the surface of the pixel electrode 161 away from the substrate substrate 11. The common electrode 163 is disposed on the surface of the light-emitting unit 162 away from the substrate 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.

[0089] The pixel electrode 161 is connected to the first source electrode 135 or the second source electrode 138. The pixel defining layer 15 is disposed on the side of the pixel electrode 161 away from the substrate substrate 11. When the thin film transistor only includes the first source electrode 135, the pixel electrode 161 is connected to the first source electrode 135, and the pixel defining layer 15 covers the pixel electrode 161 and the first planarization layer 1391. When the thin film transistor further includes the second source electrode 138, the pixel electrode 161 is connected to the second source electrode 138, and the pixel defining layer 15 covers the pixel electrode 161 and the second planarization layer 1392.

[0090] The common electrode 163 can be used as a cathode, and the pixel electrode 161 can be used as an anode. The light-emitting unit 162 can be driven to emit light by applying a signal to the pixel electrode 161. The specific light-emitting principle will not be elaborated here. The light-emitting unit 162 may contain an electroorganic light-emitting material and can be formed by processes such as evaporation. 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 stacked in sequence on the pixel electrode 161. It should be noted that according to different emission colors, 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.

[0091] In addition, the display panel of the present invention may further include a packaging layer 17, which is disposed on the side of the light-emitting layer 16 away from the substrate 11, so as to wrap the light-emitting layer 16 and prevent water and oxygen from eroding. The packaging layer 17 may be a single-layer or multi-layer structure, and the material of the packaging layer 17 may include organic or inorganic materials, which are not specifically limited herein. In this embodiment, the packaging layer 17 may include a first inorganic packaging layer 171, an organic packaging layer 172, and a second inorganic packaging layer 173. The first inorganic packaging layer 171 is disposed on the side of the light-emitting layer 16 away from the substrate 11, the organic packaging layer 172 is disposed on the side of the first inorganic packaging layer 171 away from the substrate 11, and the second inorganic packaging layer 173 is disposed on the side of the organic packaging layer 172 away from the substrate 11.

[0092] As Figures 4 to 6 shown, the display panel further includes a touch control layer 18, which can be a capacitive touch control. Among them, 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 (MetalMesh, MM), and the second touch control layer 182 is a bridge metal layer (Bridge Metal, BM). The metal mesh is located in the display area, and in the horizontal and vertical directions, the metal mesh can be divided into a touch drive (Tx) metal mesh and a touch sensing (Rx) metal mesh. Among them, one of the touch sensing (Rx) metal mesh and the touch drive (Tx) metal mesh is connected to each other, and the other is connected through the bridge metal layer.

[0093] The first touch control layer 181 is disposed on the side of the substrate 11 away from the packaging layer 17, and the second touch control layer 182 is disposed between the first touch control layer 181 and the packaging layer 17. The touch control layer 18 may further include a touch barrier layer 183 and a touch isolation layer 184. The touch barrier layer 183 is disposed between the packaging layer 17 and the second touch control layer 182, and the touch isolation layer 184 is disposed between the first touch control layer 181 and the second touch control layer 182.

[0094] The first touch control layer 181 may include a plurality of first touch units 1811, and the plurality of first touch units 1811 are arranged at intervals. The orthographic projection of the 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 touch control layer 182 may include a plurality of second touch units 1821, and the orthographic projection of the second touch unit 1821 on the substrate 11 overlaps with the orthographic projection of the first touch unit 1811 on the substrate 11.

[0095] The display panel may further include a light control layer 19. The light control layer 19 includes a first covering layer 191. The first covering layer 191 includes a plurality of first covering portions 1911. The first covering portions 1911 are disposed on a side of the first touch unit 1811 away from the substrate 11. The first covering portions 1911 cover the first touch unit 1811. A dimming opening 1912 is formed between two adjacent first covering portions 1911. An inclination angle of a side surface of the first covering portion 1911 is less than 90 degrees.

[0096] The light control layer 19 may further include a light shielding layer 192. The light shielding layer 192 includes a plurality of light shielding portions 1924. The light shielding portions 1924 are disposed on a side of the first covering portion 1911 away from the driving backplane 10. A positive projection of the light shielding portion 1924 on the substrate 11 covers a positive projection of the first touch unit 1811 on the substrate 11, that is, the positive projection of the first touch unit 1811 on the substrate 11 is located within the positive projection of the light shielding portion 1924 on the substrate 11, and an area of the positive projection of the first touch unit 1811 on the substrate 11 is smaller than an area of the positive projection of the light shielding portion 1924 on the substrate 11. A light transmission opening 1920 is formed between sides of the light shielding portions 1924 close to each other. A positive projection of the dimming opening 1912 on the substrate 11 is located within a positive projection of the light transmission opening 1920 on the substrate 11.

[0097] The light control layer 19 may further include a filter layer 195. The filter layer 195 may include a first filter portion 193 and other filter portions 194 of different colors. The other filter portions 194 of different colors include a second filter portion 1941 and a third filter portion 1942. Colors of the other filter portions 194 are different from a color of the first filter portion 193. The second filter portion 1941 and the third filter portion 1942 are respectively disposed in the dimming opening 1912 formed between two adjacent first covering portions 1911. The first filter portion 193 is disposed in the dimming opening 1912 between the second filter portion 1941 and the third filter portion 1942.

[0098] The display panel may further include a second covering layer 20. The second covering layer 20 covers a side of the first filter portion 193 and the other filter portions 194 of different colors away from the substrate 11.

[0099] The orthographic projection of the first light filtering portion 193 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 light filtering portion 1941 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 light filtering portion 1942 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 light filtering portion 193. The color of the second light emitting unit 162 is the same as the color of the second light filtering portion 1941. The color of the third light emitting unit 162 is the same as the color of the third light filtering portion 1942.

[0100] The first covering portion 1911 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 light filtering portion 193, the second light filtering portion 1941, and the third light filtering portion 1942 are generally 1.55 - 1.85. The refractive indices of the light filtering portions of the three colors are all higher than the refractive index of the first covering portion 1911. Therefore, the reflected light of the ambient light at an oblique angle can undergo total internal reflection on the side surface of the first covering portion 1911 and deflect to exit in the direction of the normal angle of view, improving the light extraction efficiency at the normal angle of view.

[0101] The display panel uses the first covering portion 1911 to insulate the first touch control unit 1811, which can reduce the thickness of the display panel. The light rays exiting at an oblique angle can undergo total internal reflection on the side surface of the first covering portion 1911 and deflect to exit in the direction of the normal angle of view, improving the light extraction efficiency at the normal angle of view without production capacity loss. Secondly, the shape of the first covering portion 1911 is trapezoidal, and its side surface is a conventional inclined surface, making it easier to control the slope angle.

[0102] Such as Figure 7 and Figure 8As shown, the light-transmitting opening 1920 includes a first light-transmitting opening 1921, a second light-transmitting opening 1922, and a third light-transmitting opening 1923. The filter layer 195 is provided with m×n groups of light-transmitting openings 1920. The m groups of light-transmitting openings 1920 extend along a first direction and are arranged along a second direction. The n groups of light-transmitting openings 1920 extend along the second direction and are arranged along the first direction. The light-transmitting openings 1920 in the same m groups are divided into two rows, and the two rows of light-transmitting openings 1920 are staggered. One row of light-transmitting openings 1920 is an alternately arranged first light-transmitting opening 1921 and third light-transmitting opening 1923, and the other row is the second light-transmitting opening 1922. The second light-transmitting opening 1922 is located between the first light-transmitting opening 1921 and the third light-transmitting opening 1923 along the first direction. The n groups of light-transmitting openings 1920 extend along the second direction and are arranged along the first direction. The light-transmitting openings 1920 in the same n groups are divided into two columns, and the two columns of light-transmitting openings 1920 are staggered. One column of light-transmitting openings 1920 is an alternately arranged first light-transmitting opening 1921 and third light-transmitting opening 1923, and the other column is the second light-transmitting opening 1922. The second light-transmitting opening 1922 is located between the first light-transmitting opening 1921 and the third light-transmitting opening 1923 along the second direction.

[0103] As Figure 7 and Figure 9 shown, the dimming opening 1912 includes a first dimming opening 1913, a second dimming opening 1914, and a third dimming opening 1915. The orthographic projection of the first dimming opening 1913 on the driving backplane 10 is located within the orthographic projection of the first light-transmitting opening 1921 on the driving backplane 10. The orthographic projection of the second dimming opening 1914 on the driving backplane 10 is located within the orthographic projection of the second light-transmitting opening 1922 on the substrate 11. The orthographic projection of the third dimming opening 1915 on the driving backplane 10 is located within the orthographic projection of the third light-transmitting opening 1925 on the substrate 11.

[0104] As Figure 7 and Figure 10 shown, the pixel opening 151 includes a first pixel opening 1511, a second pixel opening 1512, and a third pixel opening 1513. The orthographic projection of the first pixel opening 1511 on the driving backplane 10 is located within the orthographic projection of the first dimming opening 1913 on the substrate 11. The orthographic projection of the second pixel opening 1512 on the driving backplane 10 is located within the orthographic projection of the second dimming opening 1914 on the driving backplane 10. The orthographic projection of the third pixel opening 1513 on the driving backplane 10 is located within the orthographic projection of the third dimming opening 1915 on the driving backplane 10.

[0105] As Figure 7 , Figure 11 and Figure 12As shown, the orthographic projection of the first light-transmitting opening 1921 on the driving backplane 10 is located within the orthographic projection of the first light-filtering portion 193 on the driving backplane 10. The orthographic projection of the second light-transmitting opening 1922 on the driving backplane 10 is located within the orthographic projection of the second light-filtering portion 1941 on the driving backplane 10. The orthographic projection of the third light-transmitting opening 1923 on the driving backplane 10 is located within the orthographic projection of the third light-filtering portion 1942 on the driving backplane 10.

[0106] As Figure 13 shown, the first light-filtering portion 193 is provided with overlapping openings 1930 of different types. At least one type of overlapping opening 1930 has an overlapping contour line 196 and a non-overlapping contour line 197. The distance between the overlapping contour line 196 and the center of the overlapping opening 1930 is less than the distance between the non-overlapping contour line 197 and the center of the overlapping opening 1930, that is, the overlapping contour line 196 is recessed towards the center of the overlapping opening 1930 relative to the non-overlapping contour line 197. The orthographic projections of the overlapping contour lines 196 on the driving backplane 10 are respectively located within the orthographic projections of the edges of the corresponding light-transmitting openings 1920 on the driving backplane 10, and the orthographic projections of the non-overlapping contour lines 197 on the driving backplane 10 are respectively located outside the orthographic projections of the corresponding light-transmitting openings 1920 on the driving backplane 10.

[0107] The first light-filtering portion 193 overlaps with other light-filtering portions 194 of different adjacent colors. The portion of the first light-filtering portion 193 located between the edge of the overlapping contour line 196 and the edge of the corresponding light-transmitting opening 1920 forms an overlapping portion 1935. The shortest connection line between the edge of the overlapping contour line 196 and the center of the overlapping opening 1930 is a rotation line, and the angle between different rotation lines and the first direction is a rotation angle. Among the same type of overlapping openings 1930, at least some of the rotation angles of the overlapping contour lines 196 are different. As Figure 5 shown, in order to avoid blocking the light output of the light-emitting unit 162 and affecting the pixel density of the display panel, the orthographic projection of the overlapping portion 1935 on the driving backplane 10 is located within the orthographic projection of the pixel defining portion on the driving backplane 10.

[0108] In the same overlapping opening 1930, the rotation angles of some overlapping contour lines 196 can be set differently. By controlling the different rotation angles of the overlapping contour lines 196, the positions of the overlapping portions 1935 at the edges of the light-transmitting openings 1920 can be controlled differently, thereby changing the light-transmitting amounts at different positions at the edges of different light-transmitting openings 1920, so that the reflected light of the ambient light generates an interference cancellation effect when passing through different light-transmitting openings 1920, and reducing or eliminating the possibility of color separation phenomenon in the visual effect. In order to further reduce the possibility of color separation phenomenon in the visual effect, the rotation angles of all the overlapping contour lines 196 can be set to be different, and the light-transmitting amounts at different positions of all the light-transmitting openings 1920 are adjusted, so that all the light-transmitting openings 1920 generate an interference cancellation effect.

[0109] Among the same m groups of light-transmitting openings 1920, the rotation angles of different overlapping contour lines 196 are different from each other. Among the same n groups of light-transmitting openings 1920, the rotation angles of different overlapping contour lines 196 are different from each other. The rotation angles θ of the overlapping contour lines 196 of two adjacent overlapping openings 1930 of the same kind satisfy: θ2 = θ1 + p; where, the rotation angle of the overlapping contour line 196 with a smaller angle is θ1, the rotation angle of the overlapping contour line 196 with a larger angle is θ2, 0 < θ1 < θ2 ≤ 360, the interval value of the rotation angles of two adjacent overlapping contour lines 196 is a, 0 < p ≤ 360; among the m×n groups of light-transmitting openings 1920, the overlapping contour lines 196 with different rotation angles are randomly distributed in different overlapping openings 1930.

[0110] The different types of overlapping openings 1930 include a first overlapping opening 1931, and a second light-filtering portion 1941 is arranged in the first overlapping opening 1931. Figure 5 In [description], the thickness of the second light-filtering portion 1941 is greater than the thickness of the first covering portion 1911. The second light-filtering portion 1941 covers the side surface of the first covering portion 1911 and a first area on the side of the light-shielding portion 1924 away from the substrate 11. The first light-filtering portion 193 covers the side surface of the first covering portion 1911 and a second area on the side of the light-shielding portion 1924 away from the substrate 11. The first light-filtering portion 193 extends along the second area to overlap with the side of the second light-filtering portion 1941 away from the substrate 11.

[0111] The overlapping opening 1930 includes a first overlapping opening 1931 which has a first overlapping contour line 1963 and a first non - overlapping contour line 1971. The first overlapping contour line 1963 extends between the edge of the first light - transmissive opening 1921 and the edge of the second light - transmissive opening 1922. The first non - overlapping contour line 1971 extends beyond the edge of the second light - transmissive opening 1922 and into the second light - transmissive opening 1922. The part of the first light - filtering portion 193 located between the edge of the overlapping contour line 196 and the edge of the corresponding light - transmissive opening 1920 forms an overlapping portion 1935. The distance between the first overlapping contour line 1963 and the center of the first overlapping opening 1931 is less than the distance between the first non - overlapping contour line 1971 and the center of the first overlapping opening 1931.

[0112] The part of the first light - filtering portion 193 located between the edge of the second light - transmissive opening 1922 and the edge of the first overlapping contour line 1963 is the first overlapping portion 1933. The shortest connection line between the edge of the first overlapping contour line 1963 and the center of the overlapping opening 1930 is the first rotation line OA. The angle between different first rotation lines OA and the first direction is the first rotation angle, and at least part of the first rotation angles of the first overlapping contour line 1963 are different. In order to further reduce the possibility of color separation visually, it can be set that the rotation angles of all the first overlapping contour lines 1963 are different, and the light - transmissive amounts at different positions of all the second light - transmissive openings 1922 are adjusted so that all the second light - transmissive openings 1922 produce an interference - cancellation effect.

[0113] The first rotation angle θa of the first overlapping contour line 1963 of two adjacent first overlapping openings 1931 with adjacent angle sizes satisfies: θa1 = θa2 + p1; in the first overlapping opening 1931, the first rotation angle of the first overlapping contour line 1963 with a smaller angle is θa1, and the first rotation angle of the first overlapping contour line 1963 with a larger angle is θa2, 0 < θa1 < θa2 ≤ 360. The interval value p1 between the first rotation angles of two adjacent first overlapping contour lines 1963 with adjacent angle sizes is 0 < p1 ≤ 360; in the m×n groups of light - transmissive openings 1920, the first overlapping contour lines 1963 with different first rotation angles are randomly distributed in different first overlapping openings 1931. In the same m groups of light - transmissive openings 1920, the first rotation angles of different first overlapping contour lines 1963 are different from each other, and in the same n groups of light - transmissive openings 1920, the first rotation angles of different first overlapping contour lines 1963 are different from each other.

[0114] The color of the first light filtering part 193 can be red, the color of the second light filtering part 1941 can be green, and the color of the third light filtering part 1942 can be blue. The color of the first light filtering part 193 can also be blue, the color of the second light filtering part 1941 can also be red, and the color of the third light filtering part 1942 can also be green. As Figure 18 shown, the color of the first light filtering part 193 can also be green, the color of the second light filtering part 1941 can also be red, and the color of the third light filtering part 1942 can also be blue.

[0115] When the color of the first light filtering part 193 is red, the color of the second light filtering part 1941 is green, and the color of the third light filtering part 1942 is blue, the different first rotation angles θa in the 4×4 group of light transmissive openings 1920 can be set according to the rule in Table 1.

[0116] Table 1 Setting rule of different first rotation angles θa in the 4×4 group of light transmissive openings 1920 when the color of the first light filtering part 193 is red

[0117]

[0118] As Figure 6 、 Figure 7 and Figure 13 shown, the overlapping opening 1930 further includes a second overlapping opening 1932. The third light filtering part 1942 is located within the second overlapping opening 1932. The shape of the second overlapping opening 1932 is the same as the shape of the third light transmissive opening 1923. The first light filtering part 193 is located in the part between the edge of the third light transmissive opening 1923 and the edge of the second overlapping opening 1932 to form a second overlapping part 1934, and at least part of the widths of the second overlapping parts 1934 are different. In order to further reduce the possibility of color separation phenomenon visually, it can be set that the widths of all the second overlapping parts 1934 are different, and the light transmissive amounts of all the third light transmissive openings 1923 are adjusted so that all the third light transmissive openings 1923 produce the effect of destructive interference.

[0119] In the same overlapping part 1935 of the same m groups of light transmissive openings 1920, the widths of the overlapping parts 1935 are different from each other. In the same n groups of light transmissive openings 1920, the widths of the overlapping parts 1935 are different from each other. The widths d of two adjacent overlapping parts 1935 of the same kind satisfy: d2 = d1 + t; where, the width of the overlapping part 1935 with a smaller width is d1, the width of the overlapping part 1935 with a larger width is d2, and the width interval value between two adjacent overlapping parts 1935 is t.

[0120] The width of the first overlapping portion 1933 is da. The widths of two adjacent first overlapping portions 1933 with different sizes satisfy: da2 = da1 + ta; where, the width of the first overlapping portion 1933 with a smaller width is da1, the width of the first overlapping portion 1933 with a larger width is da2, and the width interval value between two adjacent first overlapping portions 1933 with different sizes is ta. In the same m groups of light-transmitting openings 1920, two first overlapping portions 1933 with different sizes are randomly distributed. In the same n groups of light-transmitting openings 1920, two first overlapping portions 1933 with different sizes are randomly distributed.

[0121] The width of the second overlapping portion 1934 is dc. The widths of two adjacent second overlapping portions 1934 with different sizes satisfy: dc2 = dc1 + tc; where, the width of the first overlapping portion 1933 with a smaller width is dc1, the width of the first overlapping portion 1933 with a larger width is dc2, and the width interval value between two adjacent first overlapping portions 1933 with different sizes is tc. In the same m groups of light-transmitting openings 1920, two second overlapping portions 1934 with different sizes are randomly distributed. In the same n groups of light-transmitting openings 1920, two second overlapping portions 1934 with different sizes are randomly distributed.

[0122] When the color of the first light filtering portion 193 is red, the width dc of the second overlapping portion 1934 in the 4×4 groups of light-transmitting openings 1920 can be set according to the rule in Table 2.

[0123] Table 2 Setting rule of the width dc of the second overlapping portion 1934 in the 4×4 groups of light-transmitting openings 1920 when the color of the first light filtering portion 193 is red

[0124]

[0125]

[0126] When the color of the first light filtering portion 193 is red, the width dc of the second overlapping portion 1934 in the 4×4 groups of light-transmitting openings 1920 can also be set according to the rule in Table 3.

[0127] Table 3 Setting rule of the width dc of the second overlapping portion 1934 in the 4×4 groups of light-transmitting openings 1920 when the color of the first light filtering portion 193 is red

[0128]

[0129] Whether according to the setting rule of the width dc of the second overlapping portion 1934 in Table 2 or according to the setting rule of the width dc of the second overlapping portion 1934 in Table 3, if any two adjacent second overlapping portions 1934 in size are taken, when dc1 is 1.5 μm, dc2 is 2 μm, so tc is 0.5 μm. The setting rule of ta can refer to tc, and ta can be set to 0.5 μm.

[0130] As Figures 14 to 19 shown, when the color of the first light filtering portion 193 is blue, the color of the second light filtering portion 1941 is red, and the color of the third light filtering portion 1942 is also green, the width dc of the first overlapping portion 1933 in the 4×4 group of light transmissive openings 1920 can be set according to the rule in Table 4.

[0131] Table 4 Setting rule of the width dc of the second overlapping portion 1934 in the 4×4 group of light transmissive openings 1920 when the color of the first light filtering portion 193 is blue

[0132]

[0133] When the color of the first light filtering portion 193 is blue, the color of the second light filtering portion 1941 is red, and the color of the third light filtering portion 1942 is also green, the width dc of the first overlapping portion 1933 in the 4×4 group of light transmissive openings 1920 can be set according to the rule in Table 5.

[0134] Table 5 Setting rule of the width dc of the first overlapping portion 1933 in the 4×4 group of light transmissive openings 1920 when the color of the third light filtering portion 1942 is also green

[0135]

[0136] Whether according to the setting rule of the width dc of the second overlapping portion 1934 in Table 4 or according to the setting rule of the width dc of the second overlapping portion 1934 in Table 5, if any two adjacent second overlapping portions 1934 in size are taken, when dc1 is 1.5 μm, dc2 is 2 μm, so tc is 0.5 μm.

[0137] As Figures 20 to 25 shown, when the color of the first light filtering portion 193 is green, the color of the second light filtering portion 1941 is red, and the color of the third light filtering portion 1942 is blue, the second overlapping opening 1932 has a second overlapping contour line 1964 and a second non - overlapping contour line 1972. The second overlapping contour line 1964 extends between the edge of the first light transmissive opening 1921 and the edge of the third light transmissive opening 1923, and the second non - overlapping contour line 1972 extends beyond the edge of the third light transmissive opening 1923 and into the third light transmissive opening 1923.

[0138] The distance between the second overlapping contour line 1964 and the center of the second overlapping opening 1932 is less than the distance between the second non-overlapping contour line 1972 and the center of the second overlapping opening 1932. The third light filtering part 1942 is located within the second overlapping opening 1932. The part of the first light filtering part 193 between the edge of the third light-transmitting opening 1923 and the edge of the second overlapping contour line 1964 is the second overlapping part 1934. The shortest connecting line between the edge of the second overlapping contour line 1964 and the center of the overlapping opening 1930 is the second rotation line OB. The angle between different second rotation lines OB and the first direction is the second rotation angle. The second rotation angles of at least part of the second overlapping contour line 1964 are different.

[0139] For the second rotation angles θb of the first overlapping contour lines 1963 of two adjacent second overlapping openings 1932 with adjacent angle sizes, it satisfies: θb1 = θb2 + p2; in the second overlapping opening 1932, the second rotation angle of the first overlapping contour line 1963 with a smaller angle is θb1, and the second rotation angle of the first overlapping contour line 1963 with a larger angle is θb2, 0 < θb1 < θb2 ≤ 360. The interval value of the second rotation angles of two adjacent first overlapping contour lines 1963 with adjacent angle sizes is p2, 0 < p1 ≤ 360; among the m×n groups of light-transmitting openings 1920, the second overlapping contour lines 1964 with different second rotation angles are randomly distributed in different second overlapping openings 1932. Among the same m groups of light-transmitting openings 1920, the second rotation angles of different second overlapping contour lines 1964 are different from each other. Among the same n groups of light-transmitting openings 1920, the second rotation angles of different second overlapping contour lines 1964 are different from each other.

[0140] When the color of the first light filtering part 193 is green, the first rotation angles θa of the first overlapping contour lines 1963 of different first overlapping openings 1931 in the 8×8 groups of light-transmitting openings 1920 can be set according to the rule in Table 6.

[0141] Table 6 Setting rule of the first rotation angles θa of the different first overlapping contour lines 1963 of different first overlapping openings 1931 in the 8×8 groups of light-transmitting openings 1920 when the color of the first light filtering part 193 is green

[0142]

[0143] When the color of the first light filtering part 193 is green, the second rotation angles θb of the second overlapping contour lines 1964 of different second overlapping openings 1932 in the 8×8 groups of light-transmitting openings 1920 can be set according to the rule in Table 7.

[0144] When the color of the first light filtering part 193 in Table 7 is green, the setting rule of the second rotation angle θb of different second overlapping outlines 1964 of different second overlapping openings 1932 in 8×8 groups of light transmissive openings 1920

[0145]

[0146]

[0147] In the figure, in the first overlapping part 1933 of the same m groups of light transmissive openings 1920, the widths of the first overlapping parts 1933 are different from each other. In the second overlapping part 1934 of the same n groups of light transmissive openings 1920, the widths of the second overlapping parts 1934 are different from each other. The width interval value between two adjacent first overlapping parts 1933 in size can be ta, and the width interval value between two adjacent second overlapping parts 1934 in size can be tc. The sizes of ta and tc can be 0.5 μm.

[0148] Along the extending direction of the edge of the light transmissive opening 1920, the width of the overlapping part 1935 remains unchanged. The overlapping outline 196 includes a first overlapping segment 1961 and a second overlapping segment 1962. Both the first overlapping segment 1961 and the non - overlapping outline 197 are arc segments. The radian of the first overlapping segment 1961 is the same as that of the non - overlapping outline 197. The second overlapping segment 1962 is a straight line. The second overlapping segment 1962 is respectively connected to both ends of the first overlapping segment 1961 and both ends of the non - overlapping outline 197. The second overlapping segment 1962 and the centers of the first overlapping segment 1961 and the non - overlapping outline 197 are located on the same straight line. To avoid affecting the light emission of the light emitting unit 162, the radian of the first overlapping segment 1961 can be set to be the same as the radian of the corresponding pixel opening 151.

[0149] The positive projection of the non - overlapping outline 197 on the driving backplane 10 is located outside the positive projection of the edge of other light filtering parts 194 on the driving backplane 10. The positive projection of the first overlapping segment 1961 on the driving backplane 10 is the first positive projection, the positive projection of the edge of the light transmissive opening 1920 on the driving backplane 10 is the second positive projection, and the positive projection of the pixel opening 151 on the driving backplane 10 is the third positive projection. The first positive projection is at least partially located between the second positive projection and the third positive projection. The positive projection of the second overlapping segment 1962 on the driving backplane 10 overlaps with both the positive projection of the edge of other light filtering parts 194 on the driving backplane 10 and the positive projection of the edge of the first light transmissive opening 1921 on the driving backplane 10.

[0150] As Figures 26 to 31As shown, along the extending direction of the edge of the light-transmitting opening 1920, the width of the overlapping portion 1935 changes. Both the overlapping contour line 196 and the non-overlapping contour line 197 are arc segments, and the curvature of the overlapping contour line 196 is different from that of the non-overlapping contour line 197. The orthographic projection of the overlapping contour line 196 on the driving backplane 10 is the first orthographic projection, the orthographic projection of the edge of the light-transmitting opening 1920 on the driving backplane 10 is the second orthographic projection, and the orthographic projection of the pixel opening 151 on the driving backplane 10 is the third orthographic projection. The first orthographic projection is at least partially located between the second orthographic projection and the third orthographic projection. To ensure that the first orthographic projection is at least partially located between the second orthographic projection and the third orthographic projection, generally, the curvature of the overlapping contour line 196 is less than that of the non-overlapping contour line 197, so that along the extending direction of the edge of the light-transmitting opening 1920, the width of the overlapping portion 1935 first gradually increases and then gradually decreases.

[0151] As Figure 32 shown, on the basis of Figure 25 , it is also possible to set the curvature of the first overlapping segment 1961 to be greater than the curvature of the light-transmitting opening 1920, so that the orthographic projection of the first overlapping segment 1961 on the driving backplane 10 overlaps with the orthographic projection of the edge of the light-transmitting opening 1920 on the driving backplane 10, thereby realizing that the width of the overlapping portion 1935 first gradually increases and then gradually decreases. The curvature of the first overlapping segment 1961 can be increased infinitely, and in the extreme case, the first overlapping segment 1961 can also be set as a straight line. It should be noted that in the above situation, the orthographic projection of the second overlapping segment 1962 on the driving backplane 10 no longer overlaps with the orthographic projection of the edge of the light-transmitting opening 1920 on the driving backplane 10.

[0152] 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.

[0153] By comparing Figure 33 with Figure 3 , it can be seen that by controlling the different rotation angles of the overlapping contour line 196, the position of the overlapping portion 1935 at the edge of the light-transmitting opening 1920 can be controlled differently, and then the light transmission amount at different positions of the edges of different light-transmitting openings 1920 can be changed. When diffracting the same color light at the edge of the overlapping opening 1930, at this time, the diffracted light waves of different overlapping openings 1930 will interfere and cancel each other, the diffraction aperture becomes lighter, and the boundary between adjacent two diffraction apertures becomes blurred. Therefore, the color separation phenomenon is improved.

[0154] Combined with Figure 34 for further analysis, gradually diffusing outward along the radial direction from the center of the diffraction aperture, in the range of a relatively small radius interval (0.000 - 0.162 μm), at the positions with the same radius, the light intensity corresponding to the curve S2 is significantly greater than the light intensity corresponding to the curve S1, which can also explain Figures 4 to 32The display panel of Figure 1 and Figure 2 has more concentrated diffracted light waves of the display panel than those in Figures 4 to 32 The display panel of Figure 1 and Figure 2 has weaker color separation phenomenon of the display panel than those in
