Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel, a method for manufacturing the display panel, and a display device. Background Technology

[0002] Currently, liquid crystal displays (LCDs) are used in various fields of life where displays are needed. Their great advantages are clear picture quality and large production volume. In pursuit of the ultimate performance, people have developed different display modes: TN, IPS, VA, etc. However, different modes have their common problems, namely, they rely on liquid crystal driving to display, which will result in slow response speed and problems such as image ghosting and color fading. This is especially prominent in the current display environment that requires high refresh rates.

[0003] A liquid crystal display device includes an array substrate and a color filter substrate assembled together, and a liquid crystal layer located between the array substrate and the color filter substrate. The liquid crystal layer comprises liquid crystal molecules, and the liquid crystal display generates an image by applying an electric field to the liquid crystal layer. In response to the electric field applied to the liquid crystal layer, the liquid crystal molecules in the liquid crystal layer rotate. Therefore, the electric field changes the orientation of the liquid crystal molecules in the liquid crystal layer, and when the orientation of the liquid crystal molecules changes, the light transmittance of the liquid crystal layer is adjusted.

[0004] Some performance characteristics of liquid crystal display devices, such as response time, are closely related to the liquid crystal layer. However, the properties of liquid crystal molecules change at low temperatures, causing liquid crystal stagnation, which in turn leads to poor image display in liquid crystal display devices. Summary of the Invention

[0006] This application discloses a display panel, including a first substrate, a second substrate, and a liquid crystal layer disposed opposite to each other.

[0010] Optionally, the thickness of the heat-absorbing layer is 200A-250A.

[0011] Optionally, the first substrate further includes a plurality of micro-bump structures disposed on the substrate and corresponding one-to-one with the spacers, wherein the micro-bump structures protrude toward the light-emitting surface of the first substrate.

[0012] Optionally, the width of the micro-convex structure is greater than or equal to the width of the color resist, and the height of the micro-convex structure is less than or equal to 1 / 3 of the width of the color resist.

Detailed Implementation

[0019] It should be understood that the terminology, specific structural and functional details used herein are merely for describing particular embodiments and are representative. However, this application may be implemented in many alternative forms and should not be construed as being limited to the embodiments set forth herein.

[0020] Figure 1 This is a schematic diagram of the structure of the display panel provided in this application, such as... Figure 1 As shown, this application discloses a display panel 100, including a first substrate 110, a second substrate 130 disposed opposite to each other, and a liquid crystal 140 layer located between the first substrate 110 and the second substrate 130. The first substrate 110 is divided into a display area and a non-display area, including: a substrate 111, a plurality of color resists 112, a plurality of black matrices 113, and a plurality of spacers 114; the plurality of color resists 112 are spaced apart on the substrate 111; the plurality of black matrices 113 are disposed one-to-one between two adjacent color resists 112; the plurality of spacers 114 are disposed one-to-one with the black matrices 113 in the display area, and each spacer 114 is at least partially located within the liquid crystal 140 layer; wherein, at least a portion of the spacers 114 absorb light and convert light energy into heat energy to heat the liquid crystal 140, thereby increasing the deflection speed of the liquid crystal 140.

[0021] Compared to existing technologies that improve the driving response speed of the display panel 100 by reducing cell thickness and viscosity of liquid crystal 140, which can affect display brightness, the first substrate 110 of the display panel 100 in this application includes: a substrate 111, a plurality of color resists 112, a plurality of black matrices 113, and a plurality of spacers 114; the plurality of color resists 112 are spaced apart on the substrate 111; the plurality of black matrices 113 are disposed one-to-one between two adjacent color resists 112; the plurality of spacers 114 are disposed one-to-one with the black matrices 113 in the display area, serving as supports to maintain the liquid crystal 140 cell between the first substrate 110 and the second substrate 130. To ensure a stable cell thickness, spacers 114 protrude into the liquid crystal 140 layer. At least a portion of the spacers 114 can absorb light and convert light energy into heat energy. This heat from the spacers 114 heats the surrounding liquid crystal 140 within the display panel 100, raising its temperature and reducing its viscosity. This allows the liquid crystal 140 with reduced viscosity to rotate rapidly under the same voltage. Thus, without reducing the cell thickness, the amount of liquid crystal 140 within the display panel 100 is maintained, improving the brightness and speed of the display panel 100.

[0022] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments.

[0023] First embodiment: Figure 2 This is a schematic cross-sectional view of the display panel provided in the first embodiment of this application, as shown below. Figure 2 As shown, the display panel 100 can be used in outdoor or indoor environments. The arrows in the figure represent light sources. The spacer 114 is made of a material containing heat-absorbing material, such as carbon nanomaterials, graphene, fullerene, etc. When the display panel 100 is used in an outdoor environment, the light source can be sunlight. After being irradiated by sunlight, the spacer 114 absorbs heat. By utilizing the unique electronic structure and light absorption characteristics of carbon nanomaterials, the photon energy of sunlight is efficiently converted into heat energy (lattice vibration energy) inside the material. Moreover, carbon nanomaterials have high thermal conductivity, and the heat energy generated by lattice vibration will be rapidly conducted inside the material, raising the temperature of the surrounding liquid crystal 140 and reducing the viscosity of the liquid crystal 140.

[0024] The content of the heat-absorbing material in each of the spacers 114 is 2%-20%, which can maintain sufficient elastic recovery rate of the spacers 114 themselves, and enable the spacers 114 to raise the temperature to a range sufficient to reduce the viscosity of the liquid crystal 140 after absorbing heat.

[0025] Furthermore, the multiple black matrices 113 are all made of a material containing heat-absorbing material, and the multiple black matrices 113 serve to block light between adjacent color resists 112. Therefore, when adding heat-absorbing material to the black matrices 113, it is necessary to ensure the light-blocking function of the black matrices 113. Each black matrix 113 contains 80%-85% of the heat-absorbing material, which can further heat the surrounding liquid crystals 140 that are close to the black matrix 113 through the surface of the black matrix 113. In this way, by using the black matrix 113 and the spacer 114 in combination, a better heating effect can be achieved. Through experiments, the inventors found that by setting the two in this way, the temperature can be raised by more than 10°C when the outdoor light intensity is high, which reduces the response speed of the display panel 100 by more than 2ms.

[0026] Figure 3 yes Figure 2 A magnified schematic diagram of a portion of region A in the middle, as shown below. Figure 2 As shown, combined with Figure 2 The first substrate 110 further includes an organic capping layer 120 and a plurality of micro-protrusion structures 119. The organic capping layer 120 is disposed on the side of the black matrix 113 and the color resist 112 away from the substrate 111, and covers the plurality of black matrices 113 and the plurality of color resists 112, isolating chemical reagents (such as cleaning solutions and adhesives) and physical friction in subsequent processes, and preventing the color filter from fading, peeling or pattern damage. The micro-protrusion structures 119 are disposed on the substrate 111 and are disposed one-to-one with the spacers 114. The micro-protrusion structures 119 protrude toward the light-emitting surface of the first substrate 110. The micro-protrusion structures 119 not only concentrate external light, but also reduce the reflectivity of the organic capping layer 120, so that more sunlight is concentrated and directed toward the light-emitting surface of the first substrate 110. The spacers 114 and the black matrix 113 absorb more light, thus converting more light energy into heat energy. This further increases the heating speed of the surrounding liquid crystal 140 and allows for higher heating temperatures. Experiments show that the micro-convex structure 119 reduces the reflectivity of the organic cover layer 120 by more than 0.5, while the temperature of the black matrix 113 and spacers 114 is increased by approximately 15°C, reducing the response time of the display panel 100 by more than 3ms. Furthermore, the micro-convex structure 119 refracts light within the display panel 100. When light emitted from the backlight of the display panel 100 reaches the micro-convex structure 119, it is refracted and changes its path, spreading outwards and improving the viewing angle.

[0027] in, Figure 4This is a schematic cross-sectional view of the micro-convex structure provided in the first embodiment of this application, as shown below. Figure 4 As shown, combined with Figure 3 Multiple micro-convex structures 119 are arranged adjacent to each other. The width d of each micro-convex structure 119 is greater than or equal to the width of the color resist 112. Each micro-convex structure 119 has a sufficiently large coverage area, which also covers part of the area of ​​the color resist 112 around the black matrix 113. After this arrangement, each area of ​​the color resist 112 corresponds to the micro-convex structure 119. When an external light source shines on the micro-convex structure 119, the light can be focused by the micro-convex structure 119, so that more light is focused and then directed towards the spacer 114, causing the temperature of the spacer 114 to rise faster, thereby accelerating the heating of the surrounding liquid crystal 140 to reduce the viscosity of the liquid crystal 140 and further improving the response speed.

[0028] The height h of the micro-convex structure 119 is less than or equal to 1 / 3 of the width of the color resist 112. This ensures that the protrusion height of the micro-convex structure 119 is not too high. The light irradiated by the micro-convex structure 119 can not only be focused onto the black matrix 113, but also ensure that more light is focused onto the spacer 114 through the micro-convex structure 119, so that the spacer 114 inserted into the liquid crystal 140 can better perform its heat absorption function.

[0029] Since the heat absorption effect of the heat-absorbing materials in the spacer 114 and the black matrix 113 has an upper limit, and part of the heat energy absorbed by the spacer 114 and the black matrix 113 is also scattered through the organic cover layer 120, the temperature of the heat-absorbing material will not rise continuously after absorbing heat, and the impact on the organic cover layer 120 is also limited. Under normal indoor lighting conditions, the temperature of the organic cover layer 120 can only reach 35°C-45°C, while under outdoor lighting conditions, the temperature of the organic cover layer 120 can only reach 40°C-55°C. The manufacturing process temperature of the color resist 112 is 230°C, and the display panel 100 can be continuously exposed to the sun without affecting the color resist 112 located under the organic cover layer 120.

[0030] Of course, the light source can also be a backlight module 200 that provides a backlight for the display panel 100. The backlight module 200 is disposed opposite to the first substrate 110. Instead of using sunlight, it directly utilizes the backlight emitted by the backlight module 200. Since the backlight module 200 is always in operation when the display panel 100 is running, it can continuously provide light to the spacer 114 and the black matrix 113, ensuring stable light source and continuous heating, so that the temperature can be relatively fixed.

[0031] The display panel also includes a polarizer 121 and an alignment layer 122. The polarizer 121 is disposed on the side of the substrate away from the color resist and is used to display images by controlling the polarization direction of light. The alignment layer 122 is disposed on the side of the organic capping layer 120 away from the black matrix and the color resist and is used to induce the liquid crystal 140 molecules to align in an orderly manner along a specific direction, providing a basis for light modulation.

[0032] Figure 5 This is a schematic diagram of the process steps for manufacturing the display panel provided in this application, as shown below. Figure 5 As shown, this application also discloses a method for preparing a display panel 100, which includes the following steps: S1: Provide a substrate; S2: A plurality of spaced black matrices are formed on the substrate; S3: Forms color resist between two adjacent black matrices; S4: Form spacers on the black matrix to form a complete first substrate; S5: The first substrate and the second substrate are arranged opposite to each other to form a cavity; S6: Inject liquid crystal into the cavity to form a complete display panel; The spacer 114 can absorb light and convert light energy into heat energy to heat the liquid crystal 140, thereby increasing the deflection speed of the liquid crystal 140 and thus improving the response speed of the panel.

[0033] Figure 6 yes Figure 5 A further flowchart of step S4 is shown below. Figure 6 As shown, the step of forming spacers on the black matrix to form a complete first substrate includes the following steps: S41: Mix the heat-absorbing material with the spacer material solution to form a mixed solution; S42: Apply the mixed solution onto the color resist and the black matrix; S43: Using an exposure and development process, the spacer is formed at the position corresponding to the black matrix.

[0034] The preparation of the black matrix 113 and the color resist 112 are both achieved through coating, pre-baking, exposure, development and high-temperature curing steps to finally form a patterned thin film. This is a conventional preparation process for the display panel 100 and will not be described in detail here.

[0035] Second embodiment: Figure 7 This is a schematic cross-sectional view of the spacer provided in the second embodiment of this application, as shown below. Figure 7As shown, as a second embodiment of this application, this embodiment differs from the first embodiment in that the spacer 114 includes a spacer body 115 and a heat-absorbing layer 116. The heat-absorbing layer 116 is disposed on the outer surface of the spacer body 115. The heat-absorbing layer 116 is made of a heat-absorbing material, which is carbon nanotube material. Carbon nanotube material is a highly elastic and highly ductile material that can be stretched. The spacer 114 itself needs to have a certain elasticity to ensure that it can produce a certain deformation displacement after the display panel 100 is pressed, so as to ensure the uniformity of the cell thickness of the display panel 100. Therefore, by wrapping the outer surface of the spacer body 115 with the heat-absorbing layer 116, the elastic function of the spacer 114 itself is also guaranteed.

[0036] The heat-absorbing layer 116 has a thickness of 200 Å to 250 Å, which ensures that the heat-absorbing layer 116 has sufficient thickness to absorb light energy, and the converted heat energy can also ensure that the liquid crystal 140 is heated to reduce its viscosity, thereby improving the response speed.

[0037] Because the spacer 114 has a relatively high height, the preparation of the spacer 114 involves first preparing a spacer body 115, and then coating the spacer body 115 with carbon nanotube material. Baking can be carried out at the same time as coating to ensure that the carbon nanotube material is firmly connected to the spacer body 115, and to ensure that the thickness of the heat-absorbing layer 116 wrapped on the spacer body 115 is uniform, thus ensuring the uniformity of overall heat generation.

[0038] Third embodiment: As a third embodiment of this application, this embodiment differs from the first and second embodiments in that the black matrix 113 does not contain heat-absorbing material, and the spacer 114 is made of a material containing heat-absorbing material. The heat-absorbing material is antimony-doped tin oxide (ATO) nanoclusters, and the proportion of antimony-doped tin oxide (ATO) nanoclusters in each spacer 114 is 20%-25%. When the spacer 114 absorbs heat, its temperature rises. When the temperature is below 25°C, the spacer 114 is still in a black light-absorbing state. When the temperature of the spacer 114 after absorbing heat is above 25°C, the spacer 114 becomes transparent, and light may pass through directly or be reflected, thus suppressing light absorption. At this time, the temperature of the spacer 114 is sufficient to heat the surrounding liquid crystal 140. After the spacer 114 conducts heat energy to the liquid crystal 140, the temperature of the spacer 114 itself drops below 25°C. At ℃, the spacer 114 returns to its black, light-absorbing state and continues to absorb heat energy. This cycle continues, suppressing high temperatures and protecting the lifespan and properties of the liquid crystal 140 and other film materials.

[0039] Fourth embodiment: Figure 8 This is a schematic cross-sectional view of the spacer structure provided in the fourth embodiment of this application, as shown below. Figure 8 As shown, as the fourth embodiment of this application, this embodiment differs from the first, second, and third embodiments in that the spacer 114 includes a first spacer portion 117 and a second spacer portion 118 connected to each other. The first spacer portion 117 is disposed on the side of the black matrix 113 away from the substrate 111, and the second spacer portion 118 is disposed on the side of the first spacer portion 117 away from the black matrix 113. The height of the first spacer portion 117 is less than the height of the second spacer portion 118, and the proportion of heat-absorbing material in the first spacer portion 117 is less than the proportion of heat-absorbing material in the second spacer portion 118. The height of the first spacer portion 117 is less than or equal to the height of the second spacer portion 118. The height of the spacer 114 is one-third of the total height. Specifically, the heat-absorbing material content in the first spacer portion 117 is 1.8%-2%, and the heat-absorbing material content in the second spacer portion 118 is 2.4%-2.6%. Thus, the spacer 114 has an inverted trapezoidal cross-section with a wider top and narrower bottom. The narrower second spacer portion 118 has a stronger light absorption capacity than the first spacer portion 117. Experiments have shown that the light absorption capacity of the second spacer portion 118 is 30% higher than that of the first spacer portion 117. This can also rapidly heat the liquid crystal 140 located near the second substrate 130 and surrounding the second spacer portion, which may have a larger gap, so as to balance the overall heating range of the spacer 114 in the liquid crystal 140.

[0040] In terms of manufacturing process, after the material of the first spacer portion 117 is coated to form a film, the material of the second spacer portion 118 is coated to form a film, and then exposure and development are performed to complete the stacking of the first spacer portion 117 and the second spacer portion 118 to form a unified spacer 114.

[0041] Figure 9 This is a block diagram of the display device provided in this application, such as... Figure 9 As shown, this application also discloses a display device 10, including a display panel 100 as described above and a backlight module 200. The backlight module 200 is disposed on one side of the display panel 100 and provides a backlight source for the display panel 100. By using the display panel 100 described above, the response speed of the display device 10 is improved and the display effect is better.

The steps listed first can be executed first, later, or even simultaneously. As long as this solution can be implemented, it should be considered to fall within the scope of protection of this application.

[0043] It should be noted that the inventive concept of this application can form many embodiments, but due to the limited space of the application documents, they cannot all be listed. Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effect will be enhanced.
