Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel, a manufacturing method thereof, and a display device. Background Art

[0002] With the continuous development of OLED (Organic Light-Emitting Diode) display technology, the application of OLED in displays such as smartphones, tablets, computers, and televisions is becoming more and more extensive. OLED displays have the advantages of being thin and light, high contrast, fast response, wide viewing angle, high brightness, and full color. In order to reduce the reflectivity of external light in OLED displays, the current mainstream solution is to attach a circular polarizer to the light-emitting surface of the OLED display. However, this solution reduces the light-emitting effect due to the large light loss of the circular polarizer. Another solution is to set a color filter on the light-emitting surface of the OLED display to improve the light-emitting efficiency through the color filter, and the effect of ambient light reflection in the OLED display can be reduced by setting a black matrix (BM).

The present application greatly reduces the possibility of ambient light entering the display panel by setting color filter dots on the surface of the color filter layer, thereby improving the display quality of the display panel, especially the display quality under strong light.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0031] Figure 1 is a schematic diagram of a display panel according to the first embodiment of the present application, see Figure 1As shown, the present application discloses a display panel 100, which includes an opening area 101 and a non-opening area 102, wherein the opening area 101 and the non-opening area 102 are mainly divided by a pixel definition layer 130, and the opening position of the pixel definition layer 130 corresponds to the light-emitting unit 120, which is the opening area 101, and the position of the pixel definition layer 130 is the non-opening area 102.

[0032] Specifically, the display panel 100 also includes a substrate 110, a light-emitting unit layer, a pixel definition layer 130, an encapsulation layer 140 and a color filter layer 150; the light-emitting unit layer is provided with a plurality of light-emitting units 120, and the plurality of light-emitting units 120 are arrayed on the substrate 110 and located in the opening area 101; the pixel definition layer 130 is provided on the substrate 110 and located in the non-opening area 102, and two adjacent light-emitting units 120 are separated by the pixel definition layer 130; the encapsulation layer 140 is provided on the light-emitting unit 120 and the pixel definition layer 130; the color filter layer 150 is provided on the encapsulation layer 140; wherein, a plurality of color filter dots 180 are provided on the surface of the color filter layer 150 facing away from the substrate 110, and at the same position of the opening area 101 or the non-opening area 102, the color of the color filter dots 180 is different from the color of the color filter layer 150.

[0033] The present application provides color filter dots 180 on the surface of the color filter layer 150, and the color filter dots 180 and the color filter layer 150 have different colors. When ambient light strikes the display panel 100, it is first filtered by the color filter dots 180, thereby reducing reflection from the color filter layer 150. Regarding the opening area 101, when the color filter dots 180 are provided on the color filter layer 150 in the opening area 101, due to the different colors of the color filter dots 180 and the color filter layer 150, some ambient light is filtered by the color filter dots 180 and then absorbed by the underlying color filter layer 150, preventing some ambient light from entering the display panel 100, resulting in light reflection. Furthermore, the color filter dots 180 can reduce light reflected from the color filter layer 150. When color filter dots 180 are disposed on the color filter layer 150 in the non-aperture area 102, the filter dots reduce the reflective effect on the color filter layer 150 in the non-aperture area 102. Some light is filtered by the filter dots and then absorbed by the color filter layer 150, significantly improving the color filter layer 150's ability to absorb ambient light. By disposing color filter dots 180 on the surface of the color filter layer 150, the present application significantly reduces the likelihood of ambient light entering the display panel 100, thereby improving the display quality of the display panel 100, particularly under strong sunlight.

[0034] Specifically, the substrate 110 is located at the bottom layer of the display panel 100. A pixel driving layer is generally formed on the substrate 110. The pixel driving layer is composed of multiple metal layers and insulating layers stacked together, and is mainly used to form multiple thin film transistors, circuits that drive the light-emitting unit 120 to emit light, etc. A pixel definition layer 130 and a light-emitting unit layer are respectively formed on the pixel driving layer.

[0035] The light-emitting unit layer is generally provided with multiple light-emitting units 120. Each light-emitting unit 120 can emit light of a single color, such as red, green, blue, or white light. When the light-emitting units 120 emit red, green, or blue light, multiple adjacent light-emitting units 120 emitting light of different colors combine to form a pixel. For example, multiple pixels may include several red light-emitting units 120 emitting red light, several green light-emitting units 120 emitting green light, and several blue light-emitting units 120 emitting blue light. Generally speaking, a pixel includes at least three light-emitting units 120 of different colors, but is not limited to light-emitting units 120 emitting red, green, and blue. It can also be composed of multiple light-emitting units 120 emitting other colors. The light-emitting unit 120 generally includes a bottom electrode 121, a light-emitting layer 122, and a top electrode 123. Because the bottom electrode 121 is formed of a metal material, ambient light entering the pixel is reflected by the bottom electrode 121 and emitted through the color filter layer 150, causing glare and other problems.

[0036] The encapsulation layer 140 generally serves the primary function of encapsulating the light-emitting unit layer to prevent external moisture or oxygen from entering the interior of the light-emitting unit 120 and causing damage to the light-emitting unit 120. The encapsulation layer 140 may be a laminated encapsulation method comprising inorganic and organic materials. For example, the encapsulation layer 140 may include a first inorganic layer 141, an organic layer 142, and a second inorganic layer 143, wherein the organic layer 142 is disposed between the first inorganic layer 141 and the second inorganic layer 143, the first inorganic layer 141 covers the light-emitting unit 120 and the pixel definition layer 130, and the color filter layer 150 is disposed on the second inorganic layer 143.

[0037] Figure 2 This is a schematic diagram of the second display panel of the first embodiment of the present application, see Figure 2As shown, in this embodiment, the color filter layer 150 includes a black matrix 170 and a plurality of color filter portions 160, the black matrix 170 is arranged in the non-opening area 102, the color filter portion 160 is arranged in the opening area 101, and adjacent color filter portions 160 are separated by the black matrix 170; wherein, in each of the non-opening areas 102, a plurality of pits 151 are arranged on the surface of the black matrix 170 facing away from the substrate 110, and a plurality of the color filter dots 180 are arranged in the plurality of the pits 151, and the material of the color filter dots 180 is the same as that of the color filter portion 160.

[0038] In the present application, color filter dots are provided on the black matrix 170 with the same material as the color filter portion 160. When external ambient light is directed toward the display panel 100, when the light is directed toward the black matrix 170, the reflection effect on the black matrix 170 is reduced due to the effect of the color filter dots. Part of the light is filtered by the color filter dots and then absorbed by the black matrix 170, which greatly improves the black matrix 170's ability to absorb ambient light, so that a small amount of light is reflected by the black matrix 170, thereby improving the display quality of the display panel 100, especially the display quality under strong light.

[0039] Specifically, the filter dots in this embodiment can be red, green, or blue filter dots 181. Ambient light generally includes the entire visible light band or a wide spectrum band. Therefore, when light is directed to the filter dots corresponding to the black matrix 170, most of the light can be filtered out by the filter dots, allowing red, green, or blue light to enter the black matrix 170. Since it is monochromatic light and the light intensity is weakened after passing through the filter dots, it is directly absorbed by the black matrix 170, thereby reducing the reflectivity of the black matrix 170.

[0040] In another embodiment, in addition to filling the pits 151 on the black matrix 170, the color filter dots can also be set above the black matrix 170 in the form of convex dots. By setting the color filter convex dots, the surface of the black matrix 170 away from the substrate 110 is uneven, so that when light is emitted to the black matrix 170, part of the light is diffusely reflected by the uneven surface, and most of the light is filtered by the color filter convex dots and then absorbed by the black matrix 170, which greatly reduces the reflection effect of the black matrix 170.

[0041] Figure 3 This is a schematic diagram of the steps of the method for manufacturing the display panel of the present application, see Figure 3 As shown, the present application also discloses a method for manufacturing a display panel, comprising the steps of:

[0042] S10: forming a pixel definition layer and a light-emitting unit layer on a substrate;

[0043] S20: forming an encapsulation layer on the light-emitting unit and the pixel definition layer;

[0044] S30: forming a color filter layer on the encapsulation layer;

[0045] S40: forming a plurality of color filter dots on a surface of the color filter layer away from the substrate;

[0046] Wherein, at the same position of the opening area or the non-opening area, the color of the color filter dots is different from the color of the color filter layer.

[0047] The present application provides color filter dots 180 on the surface of the color filter layer 150 to greatly reduce the possibility of ambient light entering the display panel 100, thereby improving the display quality of the display panel 100, especially the display quality under strong light.

[0048] Specifically, the color filter dots 180 include blue filter dots 181 , the color filter portion 160 includes a blue filter portion 163 , and the blue filter dots 181 and the blue filter portion 163 are manufactured in a synchronous process.

[0049] In this embodiment, during the formation of the color filter layer 150, the blue filter portion 163 can be selected as the last process step. Specifically, the black matrix 170 can be formed first, followed by the red filter portion 161 and the green filter portion 162. Finally, when forming the blue filter portion 163, a plurality of blue filter dots 181 are formed on the black matrix 170 in the non-opening area 102. These blue filter dots 181 can be filled within the recesses 151 of the black matrix 170 or formed as protrusions on the black matrix 170. Compared to the color filter dots 180 of other colors, even if the blue filter dots 181 reflect light, the effect is minimal due to the weaker light. Furthermore, when the display panel 100 is in low brightness or black mode, the blue filter dots 181 are less noticeable to the human eye, thereby reducing the occurrence of discoloration on the display panel 100. Of course, the specific impact of the color filter dots 180 on reality is also related to the proportion of the color filter dots 180.

[0050] In another embodiment, the display panel 100 further includes a cover plate 190. The cover plate 190 is generally formed on the color filter layer 150. In some manufacturing processes, the color filter layer 150 can be formed on the cover plate 190. The display panel 100 can be formed by first forming the color filter layer 150 on the cover plate 190 and then laminating the cover plate 190 to the substrate 110. A plurality of color filter dots 180 can be formed on the surface of the cover plate 190. The color filter dots 180 can be formed in the opening area 101 and / or the opening area 101 according to actual conditions. Subsequently, the black matrix 170, the color filter portion 160, etc. are formed.

[0051] In this embodiment, no additional process is required to form the pits 151 on the color filter portion 160 or the black matrix 170. The color filter dots 180 are first formed on the cover plate 190. Then, when the color filter portion 160 or the black matrix 170 is formed on the surface of the cover plate 190 having the color filter dots 180, the color filter portion 160 or the black matrix 170 is directly covered with the color filter dots 180, thereby omitting the process of forming the pits 151.

[0052] Figure 4 This is a top view of the black matrix of the present application, see Figure 4 As shown, the color filter dots 180 can be formed in various shapes, such as hexagons, circles, or ellipses. The size of the color filter dots 180 described in this embodiment refers to the radial width, such as the distance between two opposite sides of a hexagon, the diameter of a circle, and the major axis or minor axis of an ellipse.

[0053] In a non-opening area 102, the total area of ​​the color filter dots 180 is less than or equal to two-thirds of the area of ​​the black matrix 170. When the total area of ​​the color filter dots 180 is too large, the black state of the display panel 100 in strong light or when no display is displayed is insufficient, resulting in a color shift of the color filter dots 180. For example, when the color filter dots 180 are blue filter dots 181, when the proportion of blue filter dots 181 on the black matrix 170 is relatively large, a blue shift is likely to occur, resulting in a decrease in the quality of the display panel 100. When a certain proportion of blue filter dots 181 are set on the black matrix 170, on the one hand, the reflection of light on the black matrix 170 can be reduced, and the incident ambient light from the outside can be scattered. When the coverage area is large, the reflected light of the black matrix 170 can be minimized as much as possible. On the other hand, the reflected light formed by a certain number of blue filter dots 181 improves the emission of blue light to a certain extent, which can solve the yellowing problem of the display panel 100.

[0054] Furthermore, on the basis that the total area of ​​the color filter dots 180 meets the above conditions, the adjacent color filter dots 180 are spaced at least 3 μm apart. Relatively speaking, the color filter dots 180 do not need to be in direct contact with each other. By setting a certain spacing, a larger area of ​​the black matrix 170 can be covered while keeping the area as small as possible, thereby reducing the reflected light on the black matrix 170.

[0055] In another embodiment, within a non-opening region 102, the total number of color filter dots 180 is constant. In the width direction of the black matrix 170, the size of the color filter dots 180 is less than or equal to the ratio a of the width of the black matrix 170 to the number of color filter dots 180. The number of color filter dots 180 is the sum of the number of color filter dots 180 located on the black matrix 170 within the current non-opening region 102. For example, if n columns of color filter dots 180 are arranged along the length of the black matrix 170, and each column has m color filter dots 180, then the number of color filter dots 180 is n*m. When the width of the black matrix 170 is b, the radial width of the color filter dots 180 should be less than or equal to a=b / (n*m). Therefore, when the radial width of the color filter dots 180 is constant, the larger n is, the smaller m is, and conversely, the smaller n is, the larger m is. When the number of n and m is fixed, the size of the corresponding color filter dots 180 should not be larger than a. This ensures that the proportion of the color filter dots 180 within the non-opening area 102 is constant. Furthermore, the proportion of the color filter dots 180 in this embodiment can meet the two-thirds proportion in the previous embodiment.

[0056] Specifically, the depth of the recess 151 should be less than or equal to half the thickness of the black matrix 170. Relatively speaking, the thickness of the black matrix 170 and its light-shielding capability are limited. When the black matrix 170 is thinner, its light-shielding capability is reduced. However, the color filter dots 180 disposed within the recess 151 have a certain light-filtering capability, which can compensate for the insufficient light-shielding capability caused by the reduced thickness of the black matrix 170. The cross-sectional shape of the recess 151 can be semicircular, with a concave bottom.

[0057] Figure 5 is a schematic diagram of a display panel according to the second embodiment of the present application, see Figure 2 As shown, the present application discloses a display panel 100 . The structure of the display panel 100 in this embodiment is basically the same as that in the previous embodiment, wherein the difference lies in the color filter layer 150 , and further improvements are made to the color filter portion 160 .

[0058] Specifically, the color filter layer 150 includes a black matrix 170 and a plurality of color filter sections 160. The black matrix 170 is disposed in the non-opening area 102, and the color filter sections 160 are disposed in the opening area 101. The color filter sections 160 include a red filter section 161, a blue filter section 163, and a green filter section 162. When the light-emitting units 120 of the display panel 100 are RGB light-emitting units 120, a red light-emitting unit 120 is disposed below the red filter section 161, a blue light-emitting unit 120 is disposed below the blue filter section 163, and a green light-emitting unit 120 is disposed below the green filter section 162. Three adjacent color filter sections 160 of different colors form a pixel.

[0059] Specifically, a plurality of pits 151 are provided on the surface of the plurality of color filter portions 160 facing away from the substrate 110, and the color filter dots 180 are disposed in the pits 151. At the same position of the opening area 101, the color of the color filter dots 180 is different from the color of the color filter layer 150.

[0060] In this embodiment, a plurality of color filter dots 180 are provided on the color filter portion 160. Since the color of the color filter dots 180 is different from that of the color filter layer 150, part of the ambient light is filtered by the color filter dots 180 and then absorbed by the underlying color filter layer 150. This prevents part of the ambient light from entering the display panel 100 and causing light reflection. Furthermore, the color filter dots 180 can reduce the light reflected by the color filter layer 150.

[0061] For normal display, the color filter dots 180 have a limited presence within the color filter section 160, resulting in minimal impact on actual display. On one color filter section, the blue filter dots occupy a range of 8% to 10%. This percentage refers primarily to the area of ​​the color filter section. That is, in orthographic projection of the substrate, the projected area of ​​all blue filter dots accounts for 8% to 10% of the projected area of ​​the color filter section. Within this range, the color filter section's display, including parameters like color accuracy, is not affected. Furthermore, the placement of the color filter dots significantly reduces ambient light reflection.

[0062] The present application greatly reduces the possibility of ambient light entering the display panel 100 by setting color filter dots 180 on the surface of the color filter layer 150, thereby improving the display quality of the display panel 100, especially the display quality under strong light. The color filter dots 180 disperse most of the ambient light to prevent the ambient light from entering the interior of the display panel 100, especially entering the anode of the light-emitting unit 120 to cause light reflection, thereby improving the display effect.

[0063] Specifically, the color filter dots 180 are blue filter dots 181 or transparent filter dots 182. When the color filter portion 160 is the red filter portion 161 or the green filter portion 162, the color filter dots 180 can be blue filter dots 181 and transparent filter dots 182. When the color filter portion 160 is the blue filter portion 163, the color filter dots 180 can be color filter dots 180 of other colors or transparent filter dots 182.

[0064] In this embodiment, blue filter dots 181 are positioned at the locations of the red filter portion 161 and the green filter portion 162, respectively. Ambient light first passes through the blue filter dots 181, where it is filtered by the blue filter dots 181 to form blue light. This light then enters the red filter portion 161 or the green filter portion 162 and is absorbed, thereby achieving low-reflection display of the display panel 100 under strong light. If the display panel 100 exhibits a yellowish tint, the blue filter dots 181 positioned on the color filter portion 160 can increase the proportion of blue light and reduce the yellowish tint of the display panel 100. Furthermore, the blue filter portion 163 can be replaced with a color filter portion 160 of another color to achieve the aforementioned low-reflection effect. Among them, the transparent filter dots 182 can be formed of the same material as the flat layer, and a concave surface is formed between the flat layer and the color filter portion 160. Due to the different refractive indices between the flat layer and the color filter portion 160, some ambient light is scattered by the concave surface and cannot enter the interior of the display panel 100, thereby weakening the ambient light reflection effect at the position of the blue filter portion 163.

[0065] Relatively speaking, the solution of this embodiment can be implemented separately. For example, the solution of setting color filter dots 180 only on the color filter portion 160 and not setting color filter dots 180 on the black matrix 170 can also be implemented separately, thereby improving the display effect of the display panel 100 under strong light.

[0066] In a specific embodiment, the color filter dot 180 in this embodiment is a blue filter dot 181. Compared with the red filter dot and the green filter dot, the blue filter dot 181 can transmit blue light and also reflect a small amount of blue light. When the display panel 100 is yellowish, it compensates for the blue light and improves the display effect of the display panel 100.

[0067] In the second embodiment, blue filter dots 181 are disposed at the locations of the red filter portion 161 and the green filter portion 162, respectively. Ambient light first passes through the blue filter dots 181, where it is filtered by the blue filter dots 181 to form blue light. This light then enters the red filter portion 161 or the green filter portion 162 and is absorbed, thereby achieving low-reflection display of the display panel 100 under strong light. If the display panel 100 exhibits a yellowish tint, the blue filter dots 181 disposed on the color filter portion 160 can increase the proportion of blue light and reduce the yellowish tint of the display panel 100. Furthermore, the blue filter portion 163 can be provided with a color filter portion 160 of another color to achieve the aforementioned low-reflection effect. By disposing a plurality of color filter dots 180 on the color filter portion 160, since the color of the color filter dots 180 is different from that of the color filter layer 150, part of the ambient light is filtered by the color filter dots 180 and then absorbed by the underlying color filter layer 150. This prevents part of the ambient light from entering the display panel 100 and causing light reflection. In addition, the color filter dots 180 can reduce the light reflected by the color filter layer 150.

[0068] Figure 6 is a schematic diagram of the display device of this application, see Figure 6 As shown, the present application further discloses a display device 200, which includes a driving circuit 210 and the display panel 100 of any of the above embodiments, wherein the driving circuit 210 is used to drive the display panel 100 to display. The present application greatly reduces the possibility of ambient light entering the display panel 100 by providing color filter dots 180 on the surface of the color filter layer 150, thereby improving the display quality of the display panel 100, especially the display quality under strong light.
