Description

[0001] The present invention relates to the field of display technology, and in particular to a color film substrate and a display module. Background Art

[0002] With the development of liquid crystal display technology, users' requirements for the image quality of liquid crystal display devices are gradually increasing. For example, the pixel design of liquid crystal display devices is getting smaller and smaller. Figure 1 As shown, due to the limitations of the surface treatment technology of the substrate 01, there will inevitably be some protrusions on the surface of the substrate 01, which causes the light emitted by some pixels to be scattered when passing through the uneven parts on the surface of the substrate 01, while the light that does not pass through the uneven parts on the surface of the substrate 01 will be emitted perpendicular to the substrate 01. There is a difference in brightness observed by the user between the scattered light and the vertically emitted light, which leads to dense uneven brightness in the picture viewed by the user, namely the Sparkling phenomenon. This phenomenon is particularly obvious when the display device is in a grayscale display state, affecting the viewing experience. Summary of the Invention

[0052] Please refer to Figures 2 to 10 (The arrows in the figure represent light). In order to solve the problem of uneven brightness of the liquid crystal display device during display, the embodiment of the present application proposes a color filter substrate 1, which includes a base substrate 11, a color resist layer 12 and at least one light dispersion layer (13, 14). The base substrate 11 is a light-transmitting substrate, such as a glass substrate, for allowing display light to pass through so that the display light can enter the human eye. The color resist layer 12 is arranged on one side of the base substrate 11. Specifically, the color resist layer 12 has a plurality of groups of red, green, and blue resist units 121 for filtering the light incident from the side away from the base substrate 11 to convert the white light into the corresponding color, and then emit it through the above-mentioned base substrate 11, thereby completing the color picture display.

[0053] The light scattering layer is configured to reduce the amount of light perpendicular to the base substrate 11 that enters the base substrate 11; Figures 2 to 6As shown, a light scattering layer is provided on the side of the color resist layer 12 away from the base substrate 11; or, a light scattering layer is provided between the color resist layer 12 and the base substrate 11; or, as shown Figure 11 and Figure 12 As shown, a light scattering layer is provided on the side of the color resist layer 12 away from the substrate 11 and between the color resist layer 12 and the substrate 11. Thus, the light scattering layer can reduce the direct light rays among the light rays entering the color resist layer 12, or reduce the direct light rays among the light rays emitted from the color resist layer 12 toward the substrate 11, or reduce both the direct light rays among the light rays entering the color resist layer 12 and the direct light rays among the light rays emitted from the color resist layer 12 toward the substrate 11, thereby reducing the amount of light rays entering the substrate 11 perpendicular to the substrate 11. Because when display light passes through the substrate 11, direct light rays within the display light continue to travel straight when passing through flat surfaces on the substrate 11, while both direct light rays and oblique light rays continue to travel obliquely when passing through uneven surfaces on the substrate 11, by reducing the amount of light rays entering the substrate 11 perpendicular to the substrate 11, the proportion of direct light rays within the display light can be reduced. In other words, the proportion of oblique light rays within the display light can be increased. Since users usually view the display device from directly in front of it, the brightness of direct light is greater than that of oblique light in terms of human eye perception. Therefore, by increasing the proportion of oblique light in the display light, the brightness difference between the light in the display light can be reduced, so that the intensity of the display light received by the human eye is more uniform, and the occurrence of uneven brightness and darkness of the liquid crystal display device during display can be reduced, that is, the occurrence of sparkling can be reduced.

[0054] It should be noted that, in order to make the expression more concise, this article uses "direct light" to refer to light in a direction perpendicular to the base substrate 11, and uses "oblique light" to refer to light with an angle less than 90° or greater than 90° with the base substrate 11, that is, light that is not perpendicular to the base substrate 11.

[0055] In some embodiments, the light scattering layer includes a light-transmissive first scattering layer 13. Figure 2 and Figure 3 As shown, the first dispersion layer 13 can be arranged on the side of the color resist layer 12 away from the base substrate 11, or be arranged between the color resist layer 12 and the base substrate 11; the first dispersion layer 13 has a lens structure 132, which is used to scatter light to convert direct light into oblique light, thereby reducing direct light while increasing oblique light, so as to increase the proportion of oblique light in the light entering the base substrate 11, thereby reducing the brightness difference between the light in the display light, so that the intensity of the display light received by the human eye is more uniform.

[0056] Furthermore, in some embodiments, Figure 2 and Figure 3 As shown, the first dispersion layer 13 includes a transparent adhesive layer 131, which covers the surface of the color resist layer 12 away from the base substrate 11, or covers the surface of the base substrate 11 close to the color resist layer 12; the lens structure 132 is arranged on the side of the transparent adhesive layer 131 away from the base substrate 11, and the lens structure 132 is integrally formed with the transparent adhesive layer 131.

[0057] For example, for the first dispersion layer 13 in the aforementioned embodiment, its manufacturing steps may be: first, a layer of light-transmitting adhesive material is coated on the side of the color resist layer 12 away from the base substrate 11 or on the side of the base substrate 11 close to the color resist layer 12, and the light-transmitting adhesive material layer is photocured using a mask to cure the surface of the light-transmitting adhesive material to form the above-mentioned protruding lens structure 132, and finally, an exposure process is used to remove the uncured light-transmitting adhesive material to obtain a first dispersion layer 13 having a lens structure 132 on one side.

[0058] Furthermore, in some embodiments, the lens structure 132 includes a plurality of lenses distributed along a plane parallel to the base substrate 11 , and one side surface of each lens is connected to the corresponding light-transmitting adhesive layer 131 , and the other side is a curved surface.

[0059] In some specific embodiments, Figure 2 and Figure 4 As shown, the multiple lenses include convex lenses and / or pyramidal lenses. That is, the multiple lenses can all be convex lenses, or all be pyramidal lenses, or some of the multiple lenses can be convex lenses and others can be pyramidal lenses. Moreover, in a direction parallel to the base substrate 11, the multiple lenses are circular or square, and the multiple lenses are arranged in an array.

[0060] It should be noted that convex lenses and pyramidal mirrors have a good light deflection effect, are simple in shape, and are easy to manufacture. However, in actual production, the multiple lenses can also have other lens shapes that can deflect light; for example, the multiple lenses can also be cylindrical prisms or cylindrical semicircular mirrors. In a direction parallel to the base substrate 11, the multiple lenses are arranged parallel to each other and in parallel.

[0061] In some embodiments, the light scattering layer includes a second scattering layer 14. Figure 5 and Figure 6As shown, the second dispersion layer 14 is disposed on the side of the color resist layer 12 away from the base substrate 11, or between the color resist layer 12 and the base substrate 11. The second dispersion layer 14 includes a light-transmitting portion and a light-blocking portion disposed in the same layer; the light-blocking portion is used to block light, and the light-transmitting portion is used to allow light to pass through. In this way, when the display light enters the color resist layer 12 or passes from the color resist layer 12 to the base substrate 11, a portion of the direct light in the display light is blocked and cannot enter the base substrate 11, and only a portion of the direct light passes through the base substrate 11. This reduces the probability of the direct light passing through the flat surface of the base substrate 11 and continuing to be directed, thereby reducing the brightness difference between the display light rays, so that the display light intensity received by the human eye is more uniform.

[0062] In some embodiments, the second dispersion layer 14 includes a light-blocking mesh. The light-blocking mesh is disposed parallel to the base substrate 11. The light-blocking mesh includes a mesh body 141 made of a light-blocking material. The mesh body 141 serves as a light-blocking portion to block a portion of direct light in the display light. The mesh body 141 is formed with light-transmitting mesh holes 142. The light-transmitting mesh holes 142 serve as light-transmitting portions to allow the remaining direct light to pass through.

[0063] For example, Figures 7 to 10 As shown, the light-transmitting mesh hole 142 can be a circular hole or a rectangular hole, which is simpler and easier to manufacture.

[0064] Exemplarily, the number and size of the light-transmitting mesh holes 142 can be designed according to the actual display device conditions. For example, in the design stage, a light-blocking mesh template can be prefabricated first, and then installed in the color film substrate 1 and the display condition of the display module with the color film substrate 1 can be tested. The number and size of the light-transmitting mesh holes 142 in the light-blocking mesh template can be adjusted according to the conditions, and a new round of testing can be carried out on the adjusted light-blocking mesh template until a light-blocking mesh that meets the display requirements is obtained.

[0065] For example, the line width of the mesh body 141 may be about 5 μm. Within this range, the blocking effect of the mesh body 141 on direct light and the transmission effect of the light-transmitting mesh 142 on display light both satisfy the effect of making the display light intensity more uniform.

[0066] Alternatively, in some embodiments, the second dispersion layer 14 includes a plurality of light-blocking bodies arranged in the same layer, each light-blocking body is opaque and serves as a light-blocking portion; adjacent light-blocking bodies are spaced apart to block part of the direct light in the display light; and the intervals between adjacent light-blocking bodies constitute a light-transmitting portion to allow the remaining direct light to pass through.

[0067] For example, the light blocks may be arranged in an array.

[0068] Exemplarily, the manufacturing process of the above-mentioned light-blocking mesh and light-blocking body can be: first, a light-blocking material layer is formed on the surface of the side of the color-blocking layer 12 away from the base substrate 11, or on the surface of the side of the base substrate 11 close to the color-blocking layer 12 by coating or plating; and then the light-blocking material layer is exposed and developed using a mask to retain the corresponding shape of the light-blocking mesh or light-blocking body.

[0069] Specifically, in some embodiments, the color resist layer 12 includes a plurality of color resist units 121. Each of the color resist units 121 is configured to change light passing through it into a corresponding color, namely, red, green, and blue. The orthographic projection of each color resist unit 121 on the base substrate 11 at least partially overlaps with the orthographic projection of at least one light-transmitting portion on the base substrate 11. The orthographic projection of each color resist unit 121 on the base substrate 11 at least partially overlaps with the orthographic projection of at least one light-blocking portion on the base substrate 11. This ensures that a portion of the light passing through each color resist unit 121 or about to enter each color resist unit 121 is blocked, while the remaining portion can continue to enter the base substrate 11.

[0070] In some embodiments, as Figure 11 and Figure 12 As shown, the at least one light scattering layer includes a first scattering layer 13 and a second scattering layer 14. One of the first scattering layer 13 and the second scattering layer 14 is disposed on the side of the color resist layer 12 away from the base substrate 11, and the other is disposed between the color resist layer 12 and the base substrate 11. This can simultaneously block direct light in the display light and convert direct light in the display light into oblique light. This can further reduce the probability of direct light passing through the flat surface of the base substrate 11 and continuing to be directed, thereby further reducing the brightness difference between the light rays in the display light, thereby ensuring that the intensity of the display light received by the human eye is as uniform as possible.

[0071] Specifically, such as Figure 11 As shown, when the first dispersion layer 13 is disposed on the side of the color resist layer 12 away from the base substrate 11, and the second dispersion layer 14 is disposed between the color resist layer 12 and the base substrate 11, the transparent adhesive layer 131 in the first dispersion layer 13 covers the surface of the color resist layer 12 away from the base substrate 11, and the second dispersion layer 14 covers the surface of the base substrate 11 close to the color resist layer 12. Figure 12 As shown, when the first dispersion layer 13 is disposed between the color resist layer 12 and the base substrate 11, and the second dispersion layer 14 is disposed on the side of the color resist layer 12 away from the base substrate 11, the light-transmitting adhesive layer 131 in the first dispersion layer 13 covers the surface of the base substrate 11 close to the color resist layer 12, while the second dispersion layer 14 covers the surface of the color resist layer 12 away from the base substrate 11.

[0072] As another technical solution, an embodiment of the present application also provides a display module, which includes the color filter substrate 1 and the display substrate 2 as described above. The display substrate 2 is connected to the color filter substrate 1 in a box-type manner, and a liquid crystal material 3 is filled between the color filter substrate 1 and the display substrate 2; the display substrate 2 is configured to emit display light to the color filter substrate 1. Specifically, the display substrate 2 acts as a light source, and the light it emits is usually perpendicular to the color filter substrate 1, that is, direct light perpendicular to the base substrate 11. By adopting the color filter substrate 1 proposed in the above-mentioned multiple embodiments, this embodiment can effectively reduce the proportion of direct light in the display light, thereby reducing the brightness difference between the light in the display light, so that the intensity of the display light received by the human eye is more uniform, thereby reducing the occurrence of the Sparkling phenomenon.

[0073] It will be understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art will appreciate that various modifications and improvements can be made without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
