Description

Technical Field

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

[0066] 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, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed 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 invention and are not necessarily drawn to scale.

[0067] 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.

[0068] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the existence 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 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.

[0069] 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.

[0070] like Figure 1As shown, in order to improve the light emission efficiency of the display panel at the front viewing angle and reduce the thickness of the display panel, a first cover layer 191 is provided on the side of the touch electrode layer away from the substrate 11. The first cover layer 191 includes a plurality of first cover portions 1911. The touch electrode layer includes a plurality of touch units. The first cover portions 1911 are located on the side of the first touch unit 1811 away from the substrate 11, and the first cover portions 1911 cover the first touch unit 1811. A dimming opening 1912 is formed between the sides of the first cover portions 1911 that are close to each other. A light-shielding layer 192 is provided on the side of the first cover layer 191 away from the substrate 11. The light-shielding layer 192 includes a plurality of light-shielding portions 1921. A light-transmitting opening 1922 is formed between the sides of the light-shielding portions 1921 that are close to each other. A filter unit 193 of a different color is provided in each dimming opening 1912. The filter unit 193 covers the side of the first cover portion 1911 and extends to the side of the first cover portion 1911 away from the substrate 11.

[0071] Because the width and thickness of the first touch unit 1811 are relatively small, the side of the first cover portion 1911 is beveled. The refractive index of the filter unit 193 is greater than that of the first cover portion 1911. 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 1911 and the filter unit 193, deflecting the light emitted from the oblique angle to the direction of the normal angle. This improves the light emission efficiency of the display panel at the normal angle, thus eliminating the need for a polarizer, reducing the thickness of the display panel, and contributing to the thinning of the display panel.

[0072] like Figure 2 As shown, the orthographic projection of the dimming opening 1912 on the drive backplate 10 lies within the orthographic projection of the light-transmitting opening 1922 on the drive backplate 10, and the center of the orthographic projection of the dimming opening 1912 on the drive backplate 10 coincides with the center of the orthographic projection of the light-transmitting opening 1922 on the drive backplate 10. Figure 3 and Figure 4 As shown, because the frequencies of the reflected ambient light rays at the light-transmitting aperture 1922 and the dimming aperture 1912 are close, under poor matching conditions, the light wave S1 of the reflected ambient light rays at the light-transmitting aperture 1922 and the light wave S2 of the dimming aperture 1912 superimpose. The waveforms of the two light waves superimpose at their peaks, causing interference expansion and forming brighter optical fringes; conversely, the peaks and troughs of the two light waves superimpose, causing interference destructive and forming darker optical fringes. Therefore, optical interference easily causes poor fringing with alternating bright and dark patterns.

[0073] Based on this, embodiments of the present invention provide a display panel. For example... Figures 5 to 22As shown, the display panel includes a driving backplate 10, a pixel defining layer 15, multiple pixel electrodes 161, multiple light-emitting units 162 of different colors, a common electrode 163, a first cover layer 191, a filter layer, and a light-shielding layer 192. The pixel defining layer 15 is disposed on one side of the driving backplate 10 and includes multiple pixel defining portions. Pixel openings 151 are formed between the sides of the pixel defining portions that are close to each other. The multiple pixel electrodes 161 are respectively disposed within different pixel openings 151. The multiple light-emitting units 162 of different colors... Units 162 are respectively disposed on the side of each pixel electrode 161 away from the driving backplate 10; a common electrode 163 is disposed on the side of multiple light-emitting units 162 away from the driving backplate 10; the first cover layer 191 includes multiple first cover portions 1911, the first cover portions 1911 are disposed on the side of the common electrode 163 away from the driving backplate 10, and dimming openings 1912 are formed between the sides of the first cover portions 1911 that are close to each other, and the slope angle of the side of the first cover portion 1911 is less than 90 degrees; the filter layer includes different colors A filter unit 193 is disposed within a different dimming opening 1912. The filter unit 193 covers the side of the first covering portion 1911. The orthographic projection of the filter unit 193 onto the drive back plate 10 overlaps the orthographic projection of the light-emitting unit 162 onto the drive back plate 10. The refractive index of the filter unit 193 is greater than that of the first covering portion 1911. A light-shielding layer 192 includes multiple light-shielding portions 1921, which are disposed on the side of the first covering portion 1911 away from the drive back plate 10. A light-transmitting opening 1922 is formed between the sides of the light-transmitting parts 1921 that are close to each other. The orthographic projection of the dimming opening 1912 on the drive back plate 10 is located within the orthographic projection of the light-transmitting opening 1922 on the drive back plate 10. The light-transmitting opening 1922 has a first part 1926 and a second part 1927. The distance between the first part 1926 and the edge of the dimming opening 1912 is a first distance, and the distance between the second part 1927 and the edge of the dimming opening 1912 is a second distance. The first distance is not equal to the second distance.

[0074] The display panel includes a first cover portion 1911 and a light-shielding portion 1921. A dimming opening 1912 is formed between the adjacent sides of the first cover portion 1911, and a light-transmitting opening 1922 is formed between the adjacent sides of the light-shielding portion 1921. The orthographic projection of the dimming opening 1912 on the drive back plate 10 is located within the orthographic projection of the light-transmitting opening 1922 on the drive back plate 10. The light-transmitting opening 1922 has a first portion 1926 and a second portion 1927. The first portion 1926 is adjacent to the edge of the dimming opening 1912. The distance between the two parts is the first distance, and the distance between the edge of the second part 1927 and the dimming opening 1912 is the second distance. The first distance is not equal to the second distance, which causes the centroids of the light-transmitting opening 1922 and the dimming opening 1912 to be misaligned. This can change the frequency relationship of the reflected light from the ambient light in the light-transmitting opening 1922 and the dimming opening 1912, and avoid the possibility of interference between the light waves of the reflected light from the ambient light in the light-transmitting opening 1922 and the light waves of the dimming opening 1912, thereby eliminating stripe defects in the displayed image.

[0075] The display panel involved in the embodiments of the present invention will be described in detail below with reference to specific examples.

[0076] like Figure 5 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.

[0077] The substrate 11 can be an inorganic material substrate 11 or an organic material substrate 11. For example, in one embodiment of the present invention, the material of the substrate 11 can be a glass material such as soda-lime glass, quartz glass, or sapphire glass, or a metal material such as stainless steel, aluminum, or nickel.

[0078] 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 layer, a pressure-sensitive adhesive layer, a first polyimide layer and a second polyimide layer stacked sequentially.

[0079] 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:

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] Furthermore, the display panel of the present invention 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.

[0088] like Figure 5 As shown, 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.

[0089] 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.

[0090] 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.

[0091] like Figure 5 As shown, the display panel may further include a light control layer 19, which includes a first cover layer 191. The first cover layer 191 includes a plurality of first cover portions 1911. The first cover portions 1911 are disposed on the side of the first touch unit 1811 away from the substrate 11. The first cover portions 1911 cover the first touch unit 1811. A dimming opening 1912 is formed between two adjacent first cover portions 1911. The slope angle of the side of the first cover portion 1911 is less than 90 degrees.

[0092] The light control layer 19 may further include a light-shielding layer 192, which includes a plurality of light-shielding portions 1921. The light-shielding portions 1921 are located on the side of the first covering portion 1911 away from the driving backplate 10. The orthographic projection of the light-shielding portions 1921 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 portions 1921 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 portions 1921 on the substrate 11. A light-transmitting opening 1922 is formed between the adjacent sides of the light-shielding portions 1921. The orthographic projection of the dimming opening 1912 on the substrate 11 is located within the orthographic projection of the light-transmitting opening 1922 on the substrate 11.

[0093] The light control layer 19 may further include a filter layer, which includes filter units 193 of different colors. The filter units 193 are disposed within the dimming openings 1912 formed by two adjacent first covering portions 1911. The thickness of the filter units 193 is greater than the thickness of the first covering portions 1911. The filter units 193 cover the side of the first covering portions 1911 and the light-shielding portion 1921 is disposed in a portion of the first covering portion 1911 away from the substrate 11. The portion of the first covering portion 1911 that does not overlap with the filter units 193 is an exposed area. The light-shielding portion 1921 is disposed in the exposed area, and the distance between the light-shielding portion 1921 and the filter units 193 is greater than 0. The display panel may further include a second covering layer 20, which covers the side of the filter units 193 and the light-shielding portion 1921 away from the substrate 11, as well as the gap formed between the filter units 193 and the light-shielding portion 1921.

[0094] The different colored filter units 193 include a first filter unit 1931, a second filter unit 1932, and a third filter unit 1933. The orthographic projection of the first filter unit 1931 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 1932 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 1933 on the substrate 11 covers the orthographic projection of the third light-emitting unit 1623 on the substrate 11.

[0095] The first cover 1911 can be made of a low-refractive-index resin material with a refractive index of 1.45-1.5. The refractive index of the first filter unit 1931 is typically 1.65-1.85, and the refractive indices of the second filter unit 1932 and the third filter unit 1933 are typically 1.55-1.7. The refractive indices of the three color filter units 193 are all higher than those of the first cover 1911. Therefore, the reflected light from the ambient light at an oblique angle can undergo total internal reflection on the side of the first cover 1911, deflecting it to the direction of the normal viewing angle and improving the light output efficiency at the normal viewing angle.

[0096] The display panel uses a first cover portion 1911 to insulate the first touch unit 1811, which can reduce the thickness of the display panel. Light emitted from an oblique viewing angle can undergo total internal reflection on the side of the first cover portion 1911, deflecting it to the direction of the normal viewing angle, improving the light emission efficiency at the normal viewing angle without any energy loss. Furthermore, the first cover portion 1911 is trapezoidal in shape, with conventionally beveled sides, making the slope angle easier to control.

[0097] The distance between the first part 1926 and the edge of the dimming opening 1912 is the first distance, and the distance between the second part 1927 and the edge of the dimming opening 1912 is the second distance. The first distance is not equal to the second distance. By misaligning the centroids of the light-transmitting opening 1922 and the dimming opening 1912, the frequency relationship of the reflected light from the ambient light at the light-transmitting opening 1922 and the dimming opening 1912 can be changed. This avoids the possibility of interference between the light waves of the reflected light from the ambient light at the light-transmitting opening 1922 and the light waves of the dimming opening 1912, thereby eliminating stripe defects in the displayed image.

[0098] In this embodiment, the first portion 1926 of the light-transmitting opening 1922 may protrude relative to the second portion 1927, such that the first distance is greater than the second distance. For example... Figures 6 to 22 As shown, the first portion 1926 of the first light-transmitting opening 1923 protrudes relative to the second portion 1927, the first portion 1926 of the second light-transmitting opening 1924 protrudes relative to the second portion 1927, and the first portion 1926 of the third light-transmitting opening 1925 protrudes relative to the second portion 1927. In other embodiments, the first portion 1926 of the light-transmitting opening 1922 may also be concave relative to the second portion 1927, such that the first distance is smaller than the second distance.

[0099] The shape of the dimming opening 1912 is similar to that of the pixel opening 151, and the center of the dimming opening 1912 coincides with the center of the pixel opening 151. It should be noted that "similar shape" means that the shapes of the dimming opening 1912 and the pixel opening 151 are basically the same, only differing in size. For example, when the dimming opening 1912 is circular, the shape of the light-transmitting opening 1922 is a circle surrounding the pixel opening 151; when the dimming opening 1912 is triangular, the shape of the light-transmitting opening 1922 is a triangle surrounding the pixel opening 151; and when the dimming opening 1912 is elliptical, the shape of the light-transmitting opening 1922 is an ellipse surrounding the pixel opening 151.

[0100] The light-transmitting opening 1922 has a first portion 1926 and a second portion 1927. The shape of the second portion 1927 of the light-transmitting opening 1922 is similar to the shape of the dimming opening 1912 at the corresponding position. It should be noted that "similar shape" means that the shape of the light-transmitting opening 1922 and the shape of its second portion 1927 are basically the same, only differing in size. For example, when the dimming opening 1912 is circular, the shape of the second portion 1927 of the light-transmitting opening 1922 is a circle with a notch; when the dimming opening 1912 is triangular, the shape of the second portion 1927 of the light-transmitting opening 1922 is a triangle with a notch; and when the dimming opening 1912 is elliptical, the shape of the second portion 1927 of the light-transmitting opening 1922 is an ellipse with a notch.

[0101] like Figures 6 to 22 As shown, the light-shielding layer 192 is provided with at least three light-transmitting openings 1922, including a first light-transmitting opening 1923, a second light-transmitting opening 1924, and a third light-transmitting opening 1925. The first cover layer 191 is provided with at least three dimming openings 1912, including 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 back plate 10 is located within the orthographic projection of the first light-transmitting opening 1923 on the substrate 11. The orthographic projection of the second dimming opening 1914 on the driving back plate 10 is located within the orthographic projection of the second light-transmitting opening 1924 on the substrate 11. The orthographic projection of the third dimming opening 1915 on the driving back plate 10 is located within the orthographic projection of the third light-transmitting opening 1925 on the substrate 11. The first filter unit 1931 is disposed within the first dimming opening 1913 and the first light-transmitting opening 1923, the second filter unit 1932 is disposed within the second dimming opening 1914 and the second light-transmitting opening 1924, and the third filter unit 1933 is disposed within the third dimming opening 1915 and the third light-transmitting opening 1925.

[0102] The light-shielding layer 192 is provided with m sets of light-transmitting openings 1922 extending in the first direction and arranged in the second direction and n sets of light-transmitting openings 1922 extending in the second direction and arranged in the first direction. The m-th group of light-transmitting openings 1922 is divided into two rows, with the two rows of light-transmitting openings 1922 arranged alternately. One row of light-transmitting openings 1922 consists of alternating first light-transmitting openings 1923 and third light-transmitting openings 1925, and the other row consists of second light-transmitting openings 1924. The second light-transmitting openings 1924 are located between the first light-transmitting openings 1923 and third light-transmitting openings 1925 along the first direction. The n-th group of light-transmitting openings 1922 is divided into two columns, with the two columns of light-transmitting openings 1922 arranged alternately. One column of light-transmitting openings 1922 consists of alternating first light-transmitting openings 1923 and third light-transmitting openings 1925, and the other column consists of second light-transmitting openings 1924. The second light-transmitting openings 1924 are located between the first light-transmitting openings 1923 and third light-transmitting openings 1925 along the second direction.

[0103] All first light-transmitting openings 1923 can have their dimensions in the first direction equal to their dimensions in the second direction, and the second light-transmitting opening 1924 can have their dimensions in the first direction equal to their dimensions in the second direction. The m-th o In the group of light-transmitting openings 1922, the third light-transmitting opening 1925 has a smaller dimension in the first direction than in the second direction. The third light-transmitting openings 1925 are symmetrically arranged about the first direction, and adjacent third light-transmitting openings 1925 have opposite orientations in the first direction. eThe first light-transmitting opening 1922 has a larger dimension in the first direction than in the second direction. The third light-transmitting opening 1925 is symmetrically arranged about the second direction, and two adjacent third light-transmitting openings 1925 have opposite orientations in the second direction.

[0104] It is understood that the first light-emitting unit 1621 corresponds to the first filter unit 1931, the first dimming opening 1913, and the first light-transmitting opening 1923; the second light-emitting unit 1622 corresponds to the second filter unit 1932, the second dimming opening 1914, and the second light-transmitting opening 1924; and the third light-emitting unit 1623 corresponds to the third filter unit 1933, the third dimming opening 1915, and the third light-transmitting opening 1925. The color of the first light-emitting unit 1621 can be red, the color of the second light-emitting unit 1622 can be green, and the color of the third light-emitting unit 1623 can be blue. Similarly, the color of the first filter unit 1931 can be red, the color of the second filter unit 1932 can be green, and the color of the third filter unit 1933 can be blue.

[0105] like Figures 6 to 8 As shown, it can be the m-th o The protruding direction of the first part 1926 of the light-transmitting opening 1922 is the same as that of the mth opening. e The first part 1926 of the light-transmitting opening 1922 has a different protruding direction, and it could also be the nth opening. o The protruding direction of the first part 1926 of the light-transmitting opening 1922 is the same as that of the nth opening. e The first part 1926 of the light-transmitting opening 1922 has a different convex direction; m and n are positive integers, m o and n o If m is an odd number e and n e If the number is even, the first direction is perpendicular to the second direction.

[0106] like Figure 6 and Figure 7 As shown, the mth o In the group of light-transmitting openings 1922, the first portion 1926 of the first light-transmitting opening 1923 protrudes positively in the second direction relative to the second portion 1927; the first portion 1926 of the second light-transmitting opening 1924 protrudes positively in the second direction relative to the second portion 1927; the first portion 1926 of the third light-transmitting opening 1925 protrudes positively in the second direction relative to the second portion 1927; the m-th eIn the group of light-transmitting openings 1922, the first part 1926 of the first light-transmitting opening 1923 protrudes in the opposite direction to the second part 1927 along the second direction, the first part 1926 of the second light-transmitting opening 1924 protrudes in the opposite direction to the second part 1927 along the second direction, and the first part 1926 of the third light-transmitting opening 1925 protrudes in the opposite direction to the second part 1927 along the second direction.

[0107] in Figure 6 The first part 1926 is a triangular protrusion that protrudes relative to the second part 1927; Figure 7 The first part 1926 is an arc-shaped protrusion that protrudes relative to the second part 1927. The width of the line connecting the two ends of the first part is equal to the width of the light-transmitting opening. The mth... o The arc-shaped protrusion of the group is equivalent to stretching the light-transmitting opening 1922 upwards, the mth e The arc-shaped protrusion of the group is equivalent to pulling the light-transmitting opening 1922 downward.

[0108] like Figure 8 As shown, the nth o In the group of light-transmitting openings 1922, the first portion 1926 of the first light-transmitting opening 1923 protrudes positively in the second direction relative to the second portion 1927; the first portion 1926 of the second light-transmitting opening 1924 protrudes positively in the second direction relative to the second portion 1927; the first portion 1926 of the third light-transmitting opening 1925 protrudes positively in the second direction relative to the second portion 1927; the nth e In the group of light-transmitting openings 1922, the first part 1926 of the first light-transmitting opening 1923 protrudes in the opposite direction to the second part 1927 along the second direction, the first part 1926 of the second light-transmitting opening 1924 protrudes in the opposite direction to the second part 1927 along the second direction, and the first part 1926 of the third light-transmitting opening 1925 protrudes in the opposite direction to the second part 1927 along the second direction.

[0109] like Figures 9 to 11As shown, the first part 1926 of the first light-transmitting opening 1923 protrudes in the second direction relative to the second part 1927. In the m-th group of light-transmitting openings 1922, the first parts 1926 of the two closest first light-transmitting openings 1923 protrude in opposite directions relative to the second part 1927. One of the first light-transmitting openings 1923 has its first part 1926 protruding in the forward direction relative to the second part 1927, while the other first light-transmitting opening has its first part 1926 protruding in the reverse direction relative to the second part 1927. The first portion 1926 of the two closest second light-transmitting openings 1924 protrudes in the opposite direction to the second portion 1927. In one case, the first portion 1926 of the second light-transmitting opening 1924 protrudes forward relative to the second portion 1927, and in the other case, the first portion 1926 of the second light-transmitting opening 1924 protrudes backward relative to the second portion 1927. Similarly, the first portion 1926 of the two closest third light-transmitting openings 1925 along the first direction protrudes in the opposite direction to the second portion 1927. In one case, the first portion 1926 of the third light-transmitting opening 1925 protrudes forward relative to the second portion 1927, and in the other case, the first portion 1926 of the third light-transmitting opening 1925 protrudes backward relative to the second portion 1927.

[0110] like Figure 9 As shown, in the n groups of light-transmitting openings 1922, the first portion 1926 of the first light-transmitting opening 1923 has the same protrusion direction as the second portion 1927; the first portion 1926 of the third light-transmitting opening 1925 has the same protrusion direction as the second portion 1927; and the first portion 1926 of the second light-transmitting opening 1924 has the same protrusion direction as the second portion 1927.
