[0002] In order to improve the contrast of the display panel, a light path regulation layer may be provided on the side of the light emitting layer away from the driving backplane, thereby improving the light extraction efficiency of the display panel at a normal viewing angle.

[0003] When the exposure and development process of the light-shielding layer was adjusted, a serious peeling problem occurred in the light-shielding portion on the side of the first covering portion away from the driving backplane, causing some light-transmitting openings to become larger. The reflectivity of light in the enlarged light-transmitting openings increased, resulting in defective vertical stripes of alternating light and dark on the display panel.

[0066] The FMLOC (Flexible Multi-Layer On Cell) design is currently mainstream in the OLED touch display field. The FMLOC design involves fabricating a metal electrode layer on the encapsulation layer 17 of the display substrate. The surface of the 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 to make the display panel appear black when not illuminated. However, the polarizer causes the light intensity of the display panel to attenuate and results in a thicker display panel.

[0067] like Figure 1 As shown, in order to improve the light extraction efficiency of the display panel at a normal viewing angle and reduce the thickness of the display panel, a first covering layer 191 is provided on the side of the touch electrode layer away from the base substrate 11. 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 provided on the side of the first touch unit 1811 away from the base substrate 11. The first covering portion 1911 covers the first touch unit 1811. 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 base 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. The orthographic projection of the dimming opening 1912 on the driving backplane 10 is located within the orthographic projection of the light-transmitting opening 1922 on the driving backplane 10. 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 covering portion 1911 and extends to the side of the first covering portion 1911 away from the base substrate 11.

[0068] Because the first touch unit 1811 is relatively small in width and thickness, and the side surfaces of the first covering portion 1911 are inclined, the refractive index of the filter unit 193 is greater than that of the first covering portion 1911. Therefore, light emitted from the light-emitting unit 162 at oblique angles can be totally reflected at the interface between the side surfaces of the first covering portion 1911 and the filter unit 193, deflecting the oblique-angled light toward the normal-angle direction. This improves the light extraction efficiency of the display panel at normal angles, thus eliminating the need for a polarizer and reducing the thickness of the display panel, thereby facilitating a thinner and lighter display panel.

[0069] like Figure 2As shown, a first set of manufacturing processes is used to form multiple light-shielding portions 1921. The specific process is as follows: a light-shielding coating 21 of a first thickness is formed on the side of the first covering layer 191 away from the base substrate 11. The light-shielding coating 21 of the first thickness is baked for a first time to make the light-shielding coating 21 and the first covering layer 191 more tightly bonded. The cured light-shielding coating 21 is exposed to light of a first intensity through a mask 22. The exposed light-shielding coating 21 is developed for a second time to form multiple light-shielding blocks 211. The light-shielding blocks 211 are rinsed with a first rinse intensity. After rinsing, the light-shielding blocks 211 are baked to form the light-shielding portions 1921. During this process, the light-shielding portions 1921 are prone to remain in the dimming opening 1912.

[0070] like Figure 3 As shown, in order to improve the problem of the light shielding layer 192 remaining in the dimming opening 1912, the manufacturing process of the light shielding layer 192 has been significantly adjusted. A second set of manufacturing processes is used to form multiple light shielding portions 1921. The specific process is as follows: a light shielding coating 21 of a second thickness is formed on the side of the first cover layer 191 away from the base substrate 11, the light shielding coating 21 of the second thickness is baked for a third time to make the light shielding coating 21 and the second cover layer 20 more tightly bonded, the cured light shielding coating 21 is exposed to light of a second intensity through a mask plate 22, the exposed light shielding coating 21 is developed for a fourth time, the light shielding block 21 is rinsed with a second rinse intensity, and after rinsing, the light shielding block 211 is baked to form the light shielding portion 1921.

[0071] It should be noted that the second thickness is greater than the first thickness, the second duration is greater than the first duration, the second intensity is greater than the first intensity, the fourth duration is greater than the second duration, and the second flushing intensity is greater than the first flushing intensity.

[0072] The inverted trapezoid of the light shading block 211, when the second set of manufacturing processes is used, the angle between the side of the light shading block 211 away from the base substrate 11 and the side of the light shading block 211 becomes smaller, making the light shading block 211 weaker at the angle. The light shading block 211 is broken during the flushing process, resulting in a serious peeling problem of the light shading portion 1921 on the side of the first covering portion 1911 away from the base substrate 11. After baking, the angle between the side of the light shading block 211 close to the base substrate 11 and the side of the light shading block 211 increases, resulting in the enlargement of some light-transmitting openings 1922. The reflectivity of light in the enlarged light-transmitting openings 1922 increases, forming bright stripes, while the reflectivity in the non-enlarged light-transmitting openings 1922 is smaller, forming dark stripes, resulting in the display panel having defective vertical stripes of alternating light and dark.

[0073] Based on this, the present invention provides a display panel. Figures 4 to 21As shown, the display panel includes a driving backplane 10, a pixel defining layer 15, a plurality of pixel electrodes 161, a plurality of light-emitting units 162 of different colors, a common electrode 163, a first covering layer 191, a filter layer, a support layer 194 and a light-shielding layer 192, the pixel defining layer 15 is arranged on one side of the driving backplane 10, the pixel defining layer 15 includes a plurality of pixel defining portions 152, and a pixel opening 151 is formed between the sides of the pixel defining portions 152 that are close to each other; the plurality of pixel electrodes 161 are respectively arranged in different pixel openings 151; the plurality of light-emitting units 162 of different colors are respectively arranged on the side of each pixel electrode 161 away from the driving backplane 10; the common electrode 163 is arranged on the side of the plurality of light-emitting units 162 away from the driving backplane 10; the first covering layer 191 includes a plurality of first covering portions 1911, the first covering portion 1911 is arranged on the side of the common electrode 163 away from the driving backplane 10, and a dimming opening 1912 is formed between the sides of the first covering portions 1911 that are close to each other. The slope angle of the side of the portion 1911 is less than 90 degrees; the filter layer includes filter units 193 of different colors, each filter unit 193 is respectively arranged in 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 on the driving backplane 10 covers the orthographic projection of the light-emitting unit 162 on the driving backplane 10, and the refractive index of the filter unit 193 is greater than the refractive index of the first covering portion 1911; the support layer 194 includes a plurality of support portions 1941, the support portion 1941 is arranged on the side of the first covering portion 1911 away from the base substrate 11, the support portion 1941 is arranged around the dimming opening 1912, and a support gap 1942 is formed between two adjacent support portions 1941; the light-shielding layer 192 includes a plurality of light-shielding portions 1921, the light-shielding portions 1921 are arranged in the support gap 1942, the light-shielding portions 1921 at least cover the side surfaces of the support portions 1941, and a light-transmitting opening 1922 is formed between the sides of the light-shielding portions 1921 that are close to each other.

[0074] The display panel includes a plurality of first covering portions 1911, a plurality of supporting portions 1941, and a plurality of light shielding portions 1921. The supporting portion 1941 is provided on a side of the first covering portion 1911 away from the driving backplane 10. A supporting gap 1942 is formed between two adjacent supporting portions 1941 on the same first covering portion 1911. The light shielding portion 1921 is provided within the supporting gap 1942. A light-transmitting opening 1922 is formed between the sides of the light shielding portions 1921 that are close to each other. Before the light shielding block 211 is solidified to form the light shielding portion 1921, the supporting effect of the supporting portion 1941 prevents the light shielding block 211 from peeling off from the first covering portion 1911 during the washing process. The shape and size of each light shielding portion 1921 are substantially the same, so the shape and size uniformity of each light-transmitting opening 1922 is good, and the reflectivity of light in each light-transmitting opening 1922 is the same, thereby improving the defective vertical stripes of alternating light and dark on the display panel.

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

[0076] like Figures 4 to 6 As shown, the display panel may generally include a base substrate 11 and a driving circuit layer 13 , wherein the driving circuit layer 13 is arranged on one side of the base substrate 11 . The display panel may further include a buffer layer 12 , wherein the buffer layer 12 is arranged between the base substrate 11 and the driving circuit layer 13 .

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

[0078] In another embodiment of the present invention, the substrate 11 may be a flexible substrate 11. For example, the substrate 11 may be made of polyimide (PI). The substrate 11 may also be a composite of multiple layers. 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 in sequence.

[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. Any driving circuit may include a transistor, which may be a thin film transistor. The thin film transistor may be selected from a top-gate thin film transistor, a bottom-gate thin film transistor, or a dual-gate thin film transistor. Taking a top-gate thin film transistor as an example, the driving circuit layer 13 may include a first active layer 131, a first gate insulating layer 1321, a first gate electrode 1331, a second gate insulating layer 1322, a second gate electrode 1332, and a first source and drain metal layer, which are sequentially arranged in a direction away from the base substrate 11.

[0080] The first active layer 131 is disposed on one side of the base substrate 11. The material of the first active layer 131 can be amorphous silicon semiconductor material, low-temperature polysilicon semiconductor material, metal oxide semiconductor material, organic semiconductor material, or other types of semiconductor materials. 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 can include a channel region and two doped regions of different doping types located on either side of the channel region.

[0081] The first gate insulating layer 1321 is arranged on a side of the active layer 131 away from the substrate 11. The first gate insulating layer 1321 may cover the active layer 131 and the substrate 11. The first gate 1331 layer may include a first gate 1331. The first gate 1331 is arranged on a side of the first gate insulating layer 1321 away from the substrate 11 and is 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 a side of the first gate 1331 away from the substrate 11. The second gate insulating layer 1322 may cover the first gate 1331 and the first gate insulating layer 1321. The second gate 1332 layer may include a second gate 1332. The second gate 1332 is disposed on a side of the second gate insulating layer 1322 away from the substrate 11 and directly opposite the active layer 131. The first gate insulating layer 1321 and the second gate insulating layer 1322 are both made of insulating materials such as silicon oxide.

[0082] The thin film transistor may further include an interlayer dielectric layer 134, which is disposed on a side of the second gate electrode 1332 away from the base substrate 11. The interlayer dielectric layer 134 may cover the second gate electrode 1332 and the second gate insulating layer 1322. A first source-drain metal layer is disposed on a surface of the interlayer dielectric layer 134 away from the base substrate 11. The first source-drain metal layer may 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 the two doped regions of the corresponding first active layer 131 through vias. A protective layer 137 may also be disposed on a side of the first source electrode 135 away from the base substrate 11, and the protective layer 137 covers the first source electrode 135 and the drain electrode 136. The driving circuit layer 13 may 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 a side of the protection layer 137 away from the base substrate 11 . The first planarization layer 1391 covers the protection layer 137 .

[0083] The driving circuit layer 13 may further include a second source-drain metal layer, which is arranged on the side of the first planarization layer 1391 away from the base substrate 11. The second source-drain metal layer may include a second source electrode 138, which is connected to the first source electrode 135. The planarization layer group 139 may further include a second planarization layer 1392, which is arranged on the side of the second source electrode 138 away from the base substrate 11. The second planarization layer 1392 covers the second source electrode 138 and the first planarization layer 1391.

[0084] The display panel may further include a pixel definition layer 15 and a light-emitting layer 16. The pixel definition 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 definition layer 15 includes a plurality of pixel definition portions 152, with pixel openings 151 formed between adjacent pixel definition portions 152. The light-emitting layer 16 may include a plurality of light-emitting units 162, each disposed within a different pixel opening 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. The common electrode 163 is disposed on the surface of the light-emitting unit 162 away from the substrate 11. The pixel electrodes 161 and the common electrode 163 can be used to drive the light-emitting units 162 to emit light, thereby displaying an image.

[0085] The pixel electrode 161 is connected to the first source electrode 135 or the second source electrode 138. A pixel defining layer 15 is provided on the side of the pixel electrode 161 away from the substrate 11. When the thin film transistor includes only 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 also 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.

[0086] The common electrode 163 can serve as a cathode, and the pixel electrode 161 can serve 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 described in detail here. The light-emitting unit 162 may include an electro-induced organic light-emitting material and may be formed by a process such as evaporation. For example, the light-emitting unit 162 may include a hole injection layer, a hole transport layer, a light generating layer, an electron transport layer, and an electron injection layer sequentially stacked on the pixel electrode 161. It should be noted that 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, depending on the color of the light emitted.

[0087] In addition, the display panel of the present invention may further include an encapsulation layer 17, which is provided on the side of the light-emitting layer 16 away from the base substrate 11, thereby encapsulating the light-emitting layer 16 to prevent 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, which are not specifically limited here. 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 provided on the side of the light-emitting layer 16 away from the base substrate 11, the organic encapsulation layer 172 is provided on the side of the first inorganic encapsulation layer 171 away from the base substrate 11, and the second inorganic encapsulation layer 173 is provided on the side of the organic encapsulation layer 172 away from the base substrate 11.

[0088] The display panel also includes a touch control layer 18, which can be a mutual capacitance 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 a touch drive (Tx) metal mesh and a touch sensing (Rx) metal mesh in the horizontal and vertical directions. 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 via a bridge metal layer.

[0089] The first touch control layer 181 is disposed on a side of the base substrate 11 away from the encapsulation layer 17, and the second touch control layer 182 is disposed between the first touch control layer 181 and the encapsulation 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 encapsulation 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.

[0090] The first touch control layer 181 may include a plurality of first touch units 1811, which are spaced apart from each other. The orthographic projections of the first touch units 1811 on the base substrate 11 are located between the orthographic projections of two adjacent light-emitting units 162 on the base substrate 11. The second touch control layer 182 may include a plurality of second touch units 1821, whose orthographic projections on the base substrate 11 overlap with the orthographic projections of the first touch units 1811 on the base substrate 11.

[0091] The display panel may further include a light regulation layer 19, which 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 base substrate 11, and the first covering portions 1911 cover the first touch unit 1811. The display panel uses the first covering portions 1911 to insulate the first touch unit 1811, thereby reducing the thickness of the display panel. The orthographic projection of the first covering portion 1911 on the base substrate 11 overlaps with the orthographic projection of the pixel definition portion 152 on the base substrate 11, and the distance between the edge of the orthographic projection of the first covering portion 1911 on the base substrate 11 and the edge of the orthographic projection of the pixel definition portion 152 on the base substrate 11 is less than 3 μm.

[0092] The slope angle of the side of the first covering portion 1911 is less than 90 degrees. That is, the angle between the side of the first covering portion 1911 and the surface of the first covering portion 1911 closest to the substrate 11 is less than 90 degrees. In this embodiment, the angle between the side of the first covering portion 1911 and the surface of the first covering portion 1911 closest to the substrate 11 can be between 45 degrees and 85 degrees. The first covering portion 1911 is trapezoidal in shape, and its side surfaces are conventionally inclined, making the slope angle easier to control. A dimming opening 1912 is formed between two adjacent first covering portions 1911.

[0093] The light control layer 19 may further include a support layer 194 , wherein the support portion 1941 is made of a transparent resin different from the material of the first covering portion 1911 . The support layer 194 includes a plurality of support portions 1941 , which are disposed on a side of the first covering portion 1911 away from the base substrate 11 and surround the dimming opening 1912 .

[0094] 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 driver backplane 10, and are located within the support gap 1942. The light shielding portions 1921 at least cover the side surfaces of the support portion 1941. Light-transmitting openings 1922 are formed between the adjacent sides of the light shielding portions 1921. Due to the support provided by the support portion 1941, the light shielding portions 1921 are substantially identical in shape and size. Therefore, the shape and size of each light-transmitting opening 1922 are relatively uniform, and the reflectivity of light within each light-transmitting opening 1922 is the same, thereby improving the vertical stripes of alternating light and dark on the display panel.

[0095] The orthographic projection of the light shielding portion 1921 on the base substrate 11 covers the orthographic projection of the first touch control unit 1811 on the base substrate 11. That is, the orthographic projection of the first touch control unit 1811 on the base substrate 11 is located within the orthographic projection of the light shielding portion 1921 on the base substrate 11, and the area of ​​the orthographic projection of the first touch control unit 1811 on the base substrate 11 is smaller than the area of ​​the orthographic projection of the light shielding portion 1921 on the base substrate 11. This can reduce the reflection of ambient light by the touch control layer 18 and improve the light extraction efficiency of the display panel at normal viewing angles.

[0096] The light control layer 19 may further include a filter layer, which includes filter units 193 of different colors. The filter units 193 are arranged in the dimming opening 1912 formed by two adjacent first covering parts 1911. The filter units 193 cover the side surfaces of the first covering parts 1911. The width of the overlapping area between the orthographic projection of the filter unit 193 on the base substrate 11 and the orthographic projection of the first covering part 1911 on the base substrate 11 is less than or equal to 6 μm.

[0097] The orthographic projection of the filter unit 193 on the driver backplane 10 overlaps the orthographic projection of the light-emitting unit 162 on the driver backplane 10. The filter units 193 of different colors 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 base substrate 11 overlaps the orthographic projection of the first light-emitting unit 1621 on the base substrate 11, the orthographic projection of the second filter unit 1932 on the base substrate 11 overlaps the orthographic projection of the second light-emitting unit 1622 on the base substrate 11, and the orthographic projection of the third filter unit 1933 on the base substrate 11 overlaps the orthographic projection of the third light-emitting unit 1623 on the base substrate 11. The color of the first light-emitting unit 1621 is red, the color of the second light-emitting unit 1622 is green, and the color of the third light-emitting unit 1623 is blue. The color of the first filter unit 1931 is red, the color of the second filter unit 1932 is green, and the color of the third filter unit 1933 is blue.

[0098] The refractive index of the filter unit 193 is greater than that of the first cover portion 1911. Therefore, reflected ambient light at oblique angles can be totally reflected off the side surfaces of the first cover portion 1911, deflecting it toward the normal angle of view. This improves light extraction efficiency at normal angles without loss of energy. In this embodiment, the refractive index of the first cover portion 1911 can be a resin material with a refractive index of 1.45-1.5, while the refractive index of the filter unit 193 can be 1.65-1.75.

[0099] The side of the support portion 1941 close to the base substrate 11 is set as the first support surface, and the side of the first covering portion 1911 away from the base substrate 11 is set as the first covering surface. The edge of the first support surface close to the filter unit 193 is flush with the edge of the first covering surface close to the filter unit 193. This can ensure that the coverage area of ​​the light shielding portion 1921 is maximized, and prevent the support portion 1941 from entering the light shielding opening and affecting the optical effect inside the light shielding opening. Figure 6 As shown, a support gap 1942 is formed between two adjacent support portions 1941, the slope angle θ of the support portion 1941 is 30 degrees to 50 degrees, the angle between the side surface of the support portion 1941 and the surface of the support portion 1941 close to the base substrate 11 is 30 degrees to 50 degrees, and the thickness of the support portion 1941 is 1 μm to 2 μm.

[0100] In order to increase the coverage area of ​​the light shielding portion 1921, the light shielding portion 1921 can also be extended from the side of the support portion 1941 to the side of the support portion 1941 away from the base substrate 11, so that the light shielding portion 1921 and the side of the support portion 1941 away from the base substrate 11 form an overlapping area. In order to ensure that the light shielding portion 1921 covers the side of the first covering portion 1911 away from the base substrate 11 to a large extent, the width of the overlapping area is more than 0.6 times the width of the side of the support portion 1941 away from the base substrate 11. In this embodiment, Figure 6 As shown, the width d1 of the support portion 1941 away from the base substrate 11 is 3μm to 5μm, the width d2 of the support portion 1941 close to the base substrate 11 is less than 5μm, and the width of the overlapping area between the shading portion 1921 and the support portion 1941 away from the base substrate 11 is less than or equal to 3μm.

[0101] The filter unit 193 extends from the side of the first covering portion 1911 to cover the side of the support portion 1941 and at least a portion of the area of ​​the side of the light shielding portion 1921 away from the base substrate 11. It can be understood that the thickness of the filter unit 193 is greater than the sum of the thickness of the first covering portion 1911 and the thickness of the support portion 1941. Figure 6 As shown, in this embodiment, the thickness d3 of the supporting portion 1941 is 1 μm to 2 μm, the thickness d4 of the first covering portion 1911 is 1.5 μm to 2.5 μm, the thickness d5 of the shielding portion 1921 is 1 μm to 2.5 μm, and the thickness d6 of the filter unit 193 is 2 μm to 6 μm.

[0102] The display panel may further include a second cover layer 20, which covers the side of the filter unit 193 away from the base substrate 11 and the side of the light shielding portion 1921 away from the base substrate 11. The refractive index of the second cover layer 20 is 1.45-1.5, and the thickness of the second cover layer 20 is 3μm-6μm.

[0103] like Figure 7 and Figure 8 As shown, the material of the support portion 1941 can also be the same as that of the first covering portion 1911, and the support portion 1941 and the first covering portion 1911 can be integrally formed. When forming the first covering layer 191, the thickness of the first covering layer can be increased, and a groove with an inverted trapezoidal cross-section can be directly formed on the surface of the first covering layer away from the base substrate 11, thereby forming the first covering portion 1911 and the support portion 1941. The width d1 of the surface of the support portion 1941 away from the base substrate 11 is 3 μm to 5 μm, the width d2 of the surface of the support portion 1941 closer to the base substrate 11 is less than 5 μm, the thickness d3 of the support portion 1941 is 1 μm to 2 μm, and the slope angle θ of the support portion 1941 is 30 degrees to 50 degrees. The width of the overlapping area between the light shielding portion 1921 and the surface of the support portion 1941 away from the base substrate 11 is less than or equal to 3 μm. The thickness of the first covering portion 1911, the thickness of the light shielding portion 1921, and the thickness of the filter unit 193 are Figure 6 The same, no longer repeated here.

[0104] It can be understood that the groove is the support gap 1942, and the protrusion outside the groove is the support portion 1941. The support gap 1942 and the support portion 1941 can be formed through a single process, which is simpler and has lower process costs. The width of the support gap 1942 is usually larger than the width of the support portion 1941, and the precision requirements for the mask plate 22 are relatively low, and the production cost of the mask plate 22 is low. Therefore, the production cost of the display panel is low. The support portion 1941 is formed integrally with the first covering portion 1911, and the support portion 1941 is more tightly coupled to the first covering portion 1911, so that the support effect of the support portion 1941 is better during the flushing process.

[0105] like Figure 9 and Figure 10As shown, the material of the support portion 1941 is the same as that of the closest color filter unit 193, and both are made of the same color resist material. For example, the support portion 1941 closest to the first filter unit 1931 is also made of red color resist, the support portion 1941 closest to the second filter unit 1932 is also made of green color resist, and the support portion 1941 closest to the third filter unit 1933 is also made of blue color resist. The surface of the support portion 1941 facing away from the base substrate 11 is flush with the surface of the filter unit 193 facing away from the base substrate 11. The width d1 of the support portion 1941 facing away from the base substrate 11 is 3 μm to 5 μm, the width d2 of the support portion 1941 facing the base substrate 11 is less than 5 μm, the thickness d3 of the support portion 1941 is 1 μm to 2 μm, and the slope angle θ of the support portion 1941 is 30 degrees to 50 degrees. The width of the overlapping area between the light shielding portion 1921 and the support portion 1941 away from the base substrate 11 is less than or equal to 3 μm, and the thickness of the first covering portion 1911 and the thickness of the light shielding portion 1921 are less than or equal to 3 μm. Figure 6 The thickness of the filter unit 193 is equal to the sum of the thickness of the first covering portion 1911 and the thickness of the supporting portion 1941 .

[0106] While forming the filter unit 193, the color resist material can be directly extended from the side of the first covering portion 1911 to cover the side of the first covering portion 1911 away from the base substrate 11, thereby forming the filter unit 193 and the support portion 1941 in a single process. No additional process is required to form the support portion 1941, resulting in lower process costs. The support portion 1941 not only supports the light shielding portion 1921 but also provides a certain degree of light filtering. The color resist material and the light shielding portion 1921 are tightly fitted together, with no gap between them. This eliminates the need to extend the color resist material to cover the side of the light shielding portion 1921 away from the base substrate 11, thereby reducing the amount of color resist material used.

[0107] like Figure 11 and Figure 12 As shown, Figure 9 and Figure 10 The difference is that the side of the support portion 1941 away from the base substrate 11 is flush with the side of the filter unit 193 away from the base substrate 11. During the display panel manufacturing process, after the first filter unit 1931, the second filter unit 1932, and the third filter unit 1933 are formed in the dimming opening 1912, the support portion 1941 is formed on the side of the first covering portion 1911 away from the base substrate 11.

[0108] The width d1 of the support portion 1941 away from the base substrate 11 is 3 μm to 5 μm, the width d2 of the support portion 1941 close to the base substrate 11 is less than 5 μm, the thickness d3 of the support portion 1941 is 1 μm to 2 μm, and the slope angle θ of the support portion 1941 is 30 degrees to 50 degrees. The width of the overlapping area between the light shielding portion 1921 and the side of the support portion 1941 away from the base substrate 11 is less than or equal to 3 μm, the thickness of the first covering portion 1911, the thickness of the light shielding portion 1921 and the thickness of the first covering portion 1911 are equal to or less than 3 μm. Figure 6 The thickness of the filter unit 193 is equal to the thickness of the first covering portion 1911 .

[0109] The advantage of this display panel is that the light filter unit 193 is relatively thin, resulting in less light loss when the light emitted by the light emitting unit 162 passes through the light filter unit 193. This improves the light extraction efficiency of the display panel and further reduces the power consumption of the display panel. When using a display panel with this structure, the outer edge of the side of the support portion 1941 closer to the base substrate 11 can extend beyond the edge of the side of the first covering portion 1911 farther from the base substrate 11. Because the light filter unit 193 and the support portion 1941 are made of the same material, there is no additional impact on the light extraction effect.

[0110] like Figure 13 As shown, the material of the support portion 1941 is the same as that of the first filter unit 1931, that is, all the support portions 1941 are made of red color-resistance material. Figure 14 As shown, the material of the support portion 1941 is the same as that of the second filter unit 1932, that is, all the support portions 1941 are made of green color-resist material. Figure 15 As shown, the material of the support portion 1941 is the same as that of the first filter unit 1931, that is, all the support portions 1941 are made of blue color resist material. The advantages of the above three display panels are that all the support portions 1941 can be formed in one process while further reducing power consumption. Figure 11 The process cost of the support parts 1941 of three different colors is lower.

[0111] The display panel of the present invention is further described below with reference to a plan view.

[0112] like Figures 16 to 21As shown, support portion 1941 is provided with a support opening 1943. Support portion 1941 is arranged around dimming opening 1912. The edge of support portion 1941 extends outward relative to the edge of first covering portion 1911 away from base substrate 11, exposing a portion of first covering portion 1911. The edge of light shielding portion 1921 extends outward relative to the edge of first covering portion 1911, exposing a portion of support portion 1941. Light shielding portion 1921 fills support gap 1942 between adjacent support units. The orthographic projection of the edge of dimming opening 1912 on base substrate 11 is located between the orthographic projections of the two sides of support portion 1941 that are away from each other on base substrate 11. As shown in the figure, the filter unit 193 is arranged in the dimming opening 1912 and the supporting opening 1943, and the edges of the filter unit 193 expand outward relative to the edges of the supporting opening 1943 that are away from each other, that is, the orthographic projection of the filter unit 193 on the base substrate 11 covers the orthographic projection of the supporting portion 1941 on the base substrate 11, and the orthographic projection of part of the shading portion 1921 on the base substrate 11.

[0113] The dimming opening 1912 includes a first dimming opening 1913, a second dimming opening 1914 and a third dimming opening 1915, and the light-transmitting opening 1922 includes a first light-transmitting opening 1923, a second light-transmitting opening 1924 and a third light-transmitting opening 1925. The first filter unit 1931 is arranged in the first dimming opening 1913 and the first light-transmitting opening 1923, the second filter unit 1932 is arranged in the second dimming opening 1914 and the second light-transmitting opening 1924, and the third filter unit 1933 is arranged in the third dimming opening 1915 and the third light-transmitting opening 1925. The edge of the first filter unit 1931 expands outward away from the edge of the first dimming opening 1913 relative to the side of the support portion 1941 close to the base substrate 11, the edge of the second filter unit 1932 expands outward away from the edge of the second dimming opening 1914 relative to the side of the support portion 1941 close to the base substrate 11, and the edge of the third filter unit 1933 expands outward away from the edge of the third dimming opening 1915 relative to the side of the support portion 1941 close to the base substrate 11.

[0114] Figure 18 、 Figure 19 and Figure 16 、 Figure 17 They are basically the same, the only difference is that the material of the supporting portion 1941 is the same as the material of the first covering portion 1911 .
