Display panel and display device

Abstract

A display panel includes at least two light-shielding layers. In adjacent light-shielding layers, the edge of the light-transmitting opening on the light-shielding layer farther from the driving back panel overlaps with the edge of the light-transmitting opening on the light-shielding layer closer to the driving back panel, or the edge of the light-transmitting opening on the light-shielding layer farther from the driving back panel is at least partially located within the edge of the light-transmitting opening on the light-shielding layer closer to the driving back panel. By changing the relative positions of the light-transmitting openings on adjacent light-shielding layers, reflected ambient light exhibits destructive interference when passing through the light-transmitting openings in different layers, thereby reducing or eliminating the diffraction ring formed by reflected ambient light and improving the color separation phenomenon in the dark state of the display panel. This invention also provides a display device including the above-described display panel.

Description

Technical Field

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

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

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

[0063] 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.

[0064] like Figure 1As shown, in order to reduce the thickness of the display panel and improve the light emission gain, a color filter layer is provided on the light emission side of the light-emitting layer 16 to replace the polarizer. The color filter layer is still located on the side of the encapsulation layer 17 away from the driving backplate 10. The color filter layer includes a light-shielding part 20 and a light-filtering layer 22. The light-shielding part 20 absorbs most of the ambient light, and there is no light intensity attenuation in the light emission area of ​​the light-emitting layer 16. The emitted light is emitted directly from the light-filtering layer 22, thereby improving the light emission gain of the display panel. However, this will cause the emitted light from the light-emitting unit 162 with a large oblique angle to directly enter the light-shielding part 20, resulting in a low utilization rate of the emitted light and a large power consumption of the display panel.

[0065] like Figure 2 As shown, to improve the light emission efficiency of the display panel at the front viewing angle, a first cover layer 23 is provided on the side of the first touch control layer 181 away from the driving backplate 10. The first cover layer 23 includes multiple first cover portions 19, and the first touch control layer 181 includes multiple touch units. The first cover portions 19 are located on the side of the first touch unit 1811 away from the driving backplate 10, covering the first touch unit 1811. A dimming opening 191 is formed between the sides of the first cover portions 19 that are close to each other. A light-shielding portion 20 is provided on the side of the first cover layer 23 away from the driving backplate 10, and it has multiple light-transmitting openings 21. A first light filter portion 221, a second light filter portion 222, and a third light filter portion 223 of different colors are provided in each dimming opening 191. The first light filter portion 221, the second light filter portion 222, and the third light filter portion 223 cover the side of the first cover portion 19 and extend to the side of the first cover portion 19 away from the substrate 11.

[0066] Because the width and thickness of the first touch unit 1811 are relatively small, the side of the first cover portion 19 is beveled. The refractive indices of the first filter portion 221, the second filter portion 222, and the third filter portion 223 are greater than the refractive index of the first cover portion 19. 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 19 and the first filter portion 221, the second filter portion 222, and the third filter portion 223, deflecting the light emitted from the oblique angle to the direction of the normal angle, thus improving the light emission efficiency of the display panel at the normal angle. Therefore, there is no need to set a polarizer, reducing the thickness of the display panel and contributing to the thinning of the display panel.

[0067] But regardless Figure 1 still Figure 2 In the display panel, reflected ambient light diffracts at the edge of the light-transmitting opening 21. Since different colors of light have different wavelengths, different colors of light will produce different diffracted light waves. The diffracted light waves from different light-transmitting openings 21 will interfere and enhance to form diffraction rings of different colors. Multiple diffraction rings gradually diffuse outward, and there are relatively clear boundaries between the diffraction rings, resulting in color separation in the visual effect.

[0068] Based on this, the present invention provides a display panel. For example... Figures 3 to 19 As shown, the display panel includes a driving backplate 10, a pixel defining layer 15, and at least two light-shielding layers 20. The pixel defining layer 15 is disposed on one side of the driving backplate 10 and includes multiple pixel defining portions, with a pixel opening 151 formed between two adjacent pixel defining portions. Each light-shielding layer 20 has multiple light-transmitting openings 21. The orthographic projection of the pixel opening 151 on the driving backplate 10 is located within the orthographic projection of the light-transmitting opening 21 on the driving backplate 10. In adjacent light-shielding layers 20, The edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding portion 20 away from the drive back plate 10 overlaps with the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding portion 20 near the drive back plate 10, or the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding portion 20 away from the drive back plate 10 is at least partially located within the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding portion 20 near the drive back plate 10.

[0069] In two adjacent light-shielding layers 20, the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding layer 20 away from the driving back plate 10 overlaps with the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding layer 20 near the driving back plate 10, or the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding layer 20 away from the driving back plate 10 is at least partially located within the edge of the orthographic projection of the light-transmitting opening 21 on the light-shielding layer 20 near the driving back plate 10. By changing the relative position of the light-transmitting openings 21 on the two adjacent light-shielding layers 20, the reflected light from the ambient light produces a destructive interference effect when passing through the light-transmitting openings 21 of different layers, thereby weakening or eliminating the diffraction ring formed by the reflected light from the ambient light and improving the color separation phenomenon in the visual effect of the display panel in the dark state.

[0070] The display panel involved in the embodiments of this utility model will be described in detail below with reference to specific examples.

[0071] like Figure 3 and Figure 4 As shown, a display panel may generally include a substrate 11 and a driving circuit layer 13. The driving circuit layer 13 is disposed on one side of the substrate 11. The display panel may also include a buffer layer 12, which is disposed between the substrate 11 and the driving circuit layer 13.

[0072] The substrate 11 can be an inorganic material or an organic material. For example, in one embodiment of this invention, the substrate 11 can be made of glass materials such as soda-lime glass, quartz glass, or sapphire glass, or it can be made of metal materials such as stainless steel, aluminum, or nickel.

[0073] In another embodiment of the present invention, the substrate 11 may also be a flexible substrate 11, for example, the material of the substrate 11 may be polyimide (PI). The substrate 11 may also be a composite of multiple materials. For example, in one embodiment of the present invention, the substrate 11 may include a bottom film, a pressure-sensitive adhesive layer, a first polyimide layer and a second polyimide layer stacked sequentially.

[0074] 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:

[0075] 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.

[0076] 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.

[0077] 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.

The second planarization layer 1392 covers the second source 138 and the first planarization layer 1391.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Furthermore, the display panel of this utility model may also include an encapsulation layer 17, which is disposed on the side of the light-emitting layer 16 away from the substrate 11, thereby covering the light-emitting layer 16 and preventing water and oxygen corrosion. The encapsulation layer 17 may be a single-layer or multi-layer structure, and the material of the encapsulation layer 17 may include organic or inorganic materials, without special limitation. In this embodiment, the encapsulation layer 17 may include a first inorganic encapsulation layer 171, an organic encapsulation layer 172, and a second inorganic encapsulation layer 173. The first inorganic encapsulation layer 171 is disposed on the side of the light-emitting layer 16 away from the substrate 11, the organic encapsulation layer 172 is disposed on the side of the first inorganic encapsulation layer 171 away from the substrate 11, and the second inorganic encapsulation layer 173 is disposed on the side of the organic encapsulation layer 172 away from the substrate 11.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] The display panel may further include a first cover portion 19, which has a plurality of dimming openings 191. The orthographic projection of the pixel opening 151 on the substrate 11 lies within the orthographic projection of the dimming opening 191 on the substrate 11. The slope angle of the side of the first cover portion 19 is less than 90 degrees, specifically, the slope angle of the side of the first cover portion 19 can be 55-85 degrees. The refractive index of the filter portion is greater than the refractive index of the first cover portion 19, wherein the refractive index of the first cover portion 19 can be 1.45-1.5, and the refractive index of the filter portion is greater than or equal to 1.55. The thickness of the first cover portion 19 can be 1.5-2.5 μm.

[0087] A first light-shielding portion 201 is provided on the side of the first covering portion 19 away from the substrate 11. The first light-shielding portion 201 is a black matrix, and the thickness of the first light-shielding portion 201 can be 0.5-2μm. The orthogonal projection of the first light-shielding portion 201 on the substrate 11 covers the orthogonal projection of the first touch unit 1811 on the substrate 11. That is, the orthogonal projection of the first touch unit 1811 on the substrate 11 is located within the orthogonal projection of the first light-shielding portion 201 on the substrate 11, and the area of ​​the orthogonal projection of the first touch unit 1811 on the substrate 11 is smaller than the area of ​​the orthogonal projection of the first light-shielding portion 201 on the substrate 11.

[0088] The first light-shielding portion 201 is provided with a plurality of first light-transmitting openings 211. The edges of the first light-transmitting openings 211 are outwardly flared relative to the edges of the dimming openings 191, that is, the orthographic projection of the dimming openings 191 on the substrate 11 is located within the orthographic projection of the first light-transmitting openings 211 on the substrate 11. The distance between the edge of the orthographic projection of the first light-transmitting openings 211 on the substrate 11 and the edge of the orthographic projection of the pixel openings 151 on the substrate 11 is a first distance d1. The first distance d1 is 1.5-4 times the thickness of the first covering portion 19, and specifically, the first distance d1 can be 3-8 μm.

[0089] The display panel may further include a light filter layer 22, which may have at least three different colored filter portions. These different filter portions are disposed within different dimming openings 191. The filter portions extend along the sides of the dimming openings 191 and the first light-transmitting opening 211 to the side of the first light-shielding portion 201 away from the substrate 11. That is, the thickness of the light filter layer 22 is greater than or equal to the sum of the thicknesses of the first covering portion 19 and the first light-shielding portion 201. The display panel may further include a first covering layer 23, which is disposed on the side of the light filter layer 22 away from the substrate 11 and fills the gap between two adjacent filter portions.

[0090] The filter section with at least three different colors includes a first filter section 221, a second filter section 222 and a third filter section 223. The orthographic projection of the first filter section 221 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 section 222 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 section 223 on the substrate 11 covers the orthographic projection of the third light-emitting unit 1623 on the substrate 11.

[0091] The color of the first filter 221 can be the same as the color of the first light-emitting unit 1621, the color of the second filter 222 can be the same as the color of the second light-emitting unit 1622, and the color of the third filter 223 can be the same as the color of the third light-emitting unit 1623. For example, the first filter 221 and the first light-emitting unit 1621 can be red, the second filter 222 and the second light-emitting unit 1622 can be green, and the third filter 223 and the third light-emitting unit 1623 can be blue.

[0092] The display panel may further include a second light-shielding portion 202, which is a black matrix. The second light-shielding portion 202 has a plurality of second light-transmitting openings 212. The edge of the orthographic projection of the second light-transmitting opening 212 on the driving backplate 10 overlaps with the edge of the orthographic projection of the first light-transmitting opening 211 on the driving backplate 10, or the edge of the orthographic projection of the second light-transmitting opening 212 on the driving backplate 10 is at least partially located within the orthographic projection of the first light-transmitting opening 211 on the driving backplate 10. The distance between the edge of the orthographic projection of the second light-transmitting opening 212 on the substrate 11 and the edge of the orthographic projection of the pixel opening 151 on the substrate 11 is a second distance d2. The second distance d2 is 1-4 times the thickness of the first covering portion 19, specifically 2-8 μm. The display panel may further include a second cover layer 24, which is disposed on the side of the second light-shielding portion 202 away from the substrate 11.

[0093] The distance between the edge of the orthographic projection of the second light-transmitting opening 212 on the driving back plate 10 and the edge of the orthographic projection of the first light-transmitting opening 211 on the driving back plate 10 is a third distance d3, that is, the difference between the first distance d1 and the second distance d2 is equal to the third distance d3. The third distance d3 is 0-2 times the thickness of the first covering part 19, preferably the third distance d3 is greater than 0. By changing the relative position of the first light-transmitting opening 211 and the second light-transmitting opening 212 by the third distance d3, the light transmission difference between the first light-transmitting opening 211 and the second opening is controlled, so that the reflected light of the ambient light produces an interference cancellation effect when passing through the first light-transmitting opening 211 and the second light-transmitting opening 212 in sequence, thereby weakening or eliminating the diffraction ring formed by the reflected light of the ambient light and improving the color separation phenomenon produced in the visual effect when the display panel is in a dark state.

[0094] In the thickness direction of the display panel, the distance between the second light-shielding part 202 and the first light-shielding part 201 is a fourth distance d4, which is greater than 0. Specifically, the fourth distance d4 can be 0.5-5 times the thickness of the first covering part 19. By controlling the longitudinal optical path difference between the first light-shielding part 201 and the second light-shielding part 202 through the fourth distance d4, a certain positive gain is generated for the interference cancellation effect. It can be understood that by setting both the third distance d3 and the fourth distance d4, interference cancellation can be generated, reducing the diffraction caused by reflected ambient light and improving the color separation phenomenon in the visual effect when the display panel is in a dark state.

[0095] like Figure 5 As shown, the first light-shielding part 201 is disposed on the side of the first covering part 19 away from the drive back plate 10. The light-filtering part extends along the side of the dimming opening 191 and the side of the first light-transmitting opening 211 to the space between the first light-shielding part 201 and the second light-shielding part 202. The second light-shielding part 202 fills the gap between two adjacent light-filtering parts of different colors. Figure 4 By omitting the first cover layer 23, the second light-shielding part 202 directly covers the side of the filter part away from the substrate 11. At this time, the fourth distance d4 is equal to the thickness of the filter part between the first light-shielding part 201 and the second light-shielding part 202. This reduces the distance between the second light-shielding part 202 and the light-emitting unit 162, allowing more light to emerge from the oblique viewing angle, which helps to reduce the brightness decay rate of the display panel at the oblique viewing angle.

[0096] like Figure 6 As shown, compared to Figure 4The first covering portion 19 has a recessed portion 192. The depth of the recessed portion 192 can be less than or equal to the thickness of the first covering portion 19, that is, the recessed portion 192 penetrates the first covering portion 19. A plurality of first touch units 1811 are respectively disposed in each recessed portion 192. A first light-shielding portion 201 is disposed in the recessed portion 192 and covers the plurality of first touch units 1811. The side of the first light-shielding portion 201 away from the driving back plate 10 is lower than or flush with the side of the first covering portion 19 away from the driving back plate 10. The first covering layer 23 covers the light filter portion, the first light-shielding portion 201, and the area of ​​the first covering portion 19 not covered by the light filter portion.

[0097] By eliminating the thickness of the first light-shielding portion 201, the distance between the second light-shielding portion 202 and the light-emitting unit 162 can be reduced, thus decreasing the brightness decay rate of the display panel at oblique viewing angles. Furthermore, since the second light-shielding portion 202 is formed on the side of the first cover layer 23 away from the substrate 11, the flatness of the second light-shielding portion 202 can be ensured, preventing the accuracy of the second light-transmitting opening 212 from being affected and ensuring the effect of interference cancellation. Figure 7 As shown, in order to ensure the bonding effect between the first light-shielding part 201 and the first covering part 19, the first light-shielding part 201 can extend from the side of the recessed part 192 to the side of the first covering part 19 away from the drive back plate 10.

[0098] like Figure 8 As shown, with Figures 3 to 7 The difference lies in that at least three different colored filter portions are also stacked on the side of the first cover portion 19 away from the drive back plate 10 to form a first light-shielding portion 201, and the second light-shielding portion 202 is a black matrix. In the formed first light-shielding portion 201, the first filter portion 221 is provided on the side of the first cover portion 19 away from the substrate 11, the second filter portion 222 is provided on the side of the first filter portion 221 away from the substrate 11, and the third filter portion 223 is provided on the side of the second filter portion 222 away from the substrate 11.

[0099] like Figure 9As shown, the first cover portion 19 has a recessed portion 192. Among at least three different colored filter portions, the filter portion of the color closest to the drive back plate 10 fills the recessed portion 192 and extends to the side of the first cover portion 19 away from the drive back plate 10. In the formed first light-shielding portion 201, when the first filter portion 221 is closest to the substrate 11, the first filter portion 221 fills the recessed portion 192, and the second filter portion 222 and the third filter portion 223 are randomly stacked on the side of the first filter portion 221 away from the substrate 11. When the second filter portion 222 is closest to the substrate 11, the second filter portion 222 fills the recessed portion 192, and the first filter portion 221 and the third filter portion 223 are randomly stacked on the side of the second filter portion 222 away from the substrate 11. When the third filter portion 223 is closest to the substrate 11, the third filter portion 223 fills the recess 192, and the first filter portion 221 and the second filter portion 222 are randomly stacked on the side of the third filter portion 223 away from the substrate 11.

[0100] like Figure 10 and Figure 11 As shown, with Figure 8 and Figure 9 The difference lies in that at least two different colored filter portions are also stacked on the side of the first cover portion 19 away from the driving back plate 10 to form a first light-shielding portion 201, and the second light-shielding portion 202 is a black matrix. In the formed first light-shielding portion 201, the first filter portion 221 may be disposed on the side of the first cover portion 19 away from the substrate 11, and the second filter portion 222 may be disposed on the side of the first filter portion 221 away from the substrate 11. Alternatively, the first filter portion 221 may be disposed on the side of the first cover portion 19 away from the substrate 11, and the third filter portion 223 may be disposed on the side of the first filter portion 221 away from the substrate 11. Another possibility is that the second filter portion 222 may be disposed on the side of the first cover portion 19 away from the substrate 11, and the third filter portion 223 may be disposed on the side of the first filter portion 221 away from the substrate 11.

[0101] exist Figure 8 and Figure 10 In the illustrated embodiment, when two or three light-filtering sections are stacked on the side of the first cover 19 away from the substrate 11 to form the first light-shielding section 201, the first touch control layer 181 is disposed on the side of the first cover 23 away from the driving back plate 10. The first touch control layer 181 includes a plurality of first touch units 1811, and the second light-shielding section 202 covers the plurality of first touch units 1811.

[0102] like Figure 11As shown, the first cover portion 19 has a recessed portion 192. Among at least two different colored filter portions, the filter portion of the color closest to the drive back plate 10 fills the recessed portion 192 and extends to the side of the first cover portion 19 away from the drive back plate 10. In the formed first light-shielding portion 201, when the first filter portion 221 is closest to the substrate 11, the first filter portion 221 fills the recessed portion 192; when the second filter portion 222 is closest to the substrate 11, the second filter portion 222 fills the recessed portion 192; and when the third filter portion 223 is closest to the substrate 11, the third filter portion 223 fills the recessed portion 192.

[0103] exist Figure 9 and Figure 11 In the embodiment shown, first touch units 1811 are respectively disposed in each recess 192, and a color filter portion of one color closest to the driving back plate 10 covers multiple first touch units 1811. When the first filter portion 221 fills the recess 192, the first filter portion 221 covers multiple first touch units 1811; when the second filter portion 222 fills the recess 192, the second filter portion 222 covers multiple first touch units 1811; when the third filter portion 223 fills the recess 192, the third filter portion 223 covers multiple first touch units 1811.

[0104] like Figure 12 As shown, the first light-shielding portion 201 is a black matrix, and at least three different colored filter portions are stacked on the side of the first light-shielding portion 201 away from the driving backplate 10 to form the second light-shielding portion 202. The filter portion closest to the first light-shielding portion 201 surrounds the first light-shielding portion 201. For example, the first filter portion 221 surrounds the first light-shielding portion 201, the second filter portion 222 is disposed on the side of the first filter portion 221 away from the substrate 11, and the third filter portion 223 is disposed on the side of the second filter portion 222 away from the substrate 11.

[0105] like Figure 13As shown, the first light-shielding portion 201 is a black matrix. Two adjacent light-filtering portions of different colors extend to the side of the first light-shielding portion 201 away from the driving backplate 10. Another light-filtering portion of different colors fills the space between the two adjacent light-filtering portions of different colors and extends to the side of the two adjacent light-filtering portions of different colors away from the driving backplate 10, forming the second light-shielding portion 202. Alternatively, the first light-filtering portion 221 and the second light-filtering portion 222 can be disposed on the side of the first cover portion 19 away from the substrate 11, and the third light-filtering portion 223 can be disposed on the side of the first light-filtering portion 221 and the second light-filtering portion 222 away from the substrate 11. Alternatively, the first light-filtering portion 221 and the third light-filtering portion 223 can be disposed on the side of the first cover portion 19 away from the substrate 11, and the second light-filtering portion 222 can be disposed on the side of the first light-filtering portion 221 and the third light-filtering portion 223 away from the substrate 11. Alternatively, the second filter portion 222 and the third filter portion 223 can be disposed on the side of the first cover portion 19 away from the substrate 11, and the first filter portion 221 can be disposed on the side of the second filter portion 222 and the third filter portion 223 away from the substrate 11.

[0106] like Figure 14 As shown, the first light-shielding portion 201 is a black matrix. Among the two adjacent light-filtering portions of different colors, one color of the light-filtering portion extends to the side of the first light-shielding portion 201 away from the driving backplate 10 and covers the first light-shielding portion 201. The other color of the light-filtering portion extends and overlaps with the side of the first color of the light-filtering portion away from the driving backplate 10, forming the second light-shielding portion 202. Among the three adjacent light-filtering portions of different colors, the first light-filtering portion 221 may cover one first light-shielding portion 201, a part of the second light-filtering portion 222 may overlap with the side of the first light-filtering portion 221 away from the substrate 11, another part of the second light-filtering portion 222 may cover another first light-shielding portion 201, and the third light-filtering portion 223 may overlap with the side of the second light-filtering portion 222 away from the substrate 11.

[0107] like Figure 15 As shown, alternatively, two adjacent light-blocking filters of different colors extend to the side of the first light-blocking portion 201 away from the drive backplate 10, and another light-blocking filter of different colors fills the space between the two adjacent light-blocking filters of different colors and extends to the side of the two adjacent light-blocking filters of different colors away from the drive backplate 10, forming a portion of the second light-blocking portion 202. In the case of two adjacent light-blocking filters of different colors, one color extends to the side of the first light-blocking portion 201 away from the drive backplate 10 and covers the first light-blocking portion 201, while the other color extends and overlaps to the side of the first color filter away from the drive backplate 10, forming another portion of the second light-blocking portion 202.

[0108] It should be noted that for most display devices, the first touch unit 1811 can be located between the encapsulation layer 17 and the first cover portion 19, within the first recess 192, or between the second light-shielding portion 202 and the first cover layer 23. The distance between the first touch unit 1811 and the common electrode 163 mainly affects the noise of the touch signal. Different display devices have different requirements for touch signal noise. For medium to large-sized display devices, such as laptops or tablets, which use an active pen, the touch signal noise needs to be relatively low. Therefore, the first touch unit 1811 needs to be moved as far away from the driving backplate 10 as possible to increase the distance between the first touch unit 1811 and the common electrode 163.

[0109] compared to Figure 16 The diffraction effect diagram before improvement is shown. In all the above embodiments, when the third distance d3 is 0 μm and the fourth distance d4 is 1.5 μm, the spots on the upper and lower sides and the left and right sides of the diffraction center disappear, and the color separation phenomenon caused by the enhanced interference of diffracted light waves is slightly improved, such as... Figure 17 As shown. When the third distance d3 is 0.6 μm and the fourth distance d4 is 4.3 μm, the diagonal diagonal diffraction at the diffraction center disappears, and the spots on the upper, lower, left, and right sides of the diffraction center disappear. The color separation phenomenon caused by the enhanced interference of diffracted light waves is further improved, as shown. Figure 18 As shown. When the third distance d3 is 0 μm and the fourth distance d4 is 4.3 μm, the diagonal diagonal diffraction at the diffraction center disappears, the spots on the upper and lower sides and the left and right sides of the diffraction center disappear, and the number of diffraction rings decreases. The color separation phenomenon caused by the enhanced interference of diffracted light waves is significantly improved, as shown. Figure 19 As shown.
