[0042] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0045] Embodiment 1

[0046] Refer to Figures 1 to 3 An embodiment 1 of the substrate of the present invention is proposed.

[0047] Refer to Figures 1 to 3 , in Embodiment 1, the substrate includes: a transparent substrate 10, a black matrix 20 and a color resist layer. The black matrix 20 and the color resist layer are disposed on the transparent substrate 10. A plurality of spaced-apart opening regions are provided on the black matrix 20. The color resist layer is located within the opening regions. The color resist layer includes a plurality of color resist blocks 30, and the color resist blocks 30 correspond to the opening regions one by one. The substrate further includes: a first dimming color resist block 40;

[0048] The first dimming color resist block 40 is disposed on at least one of the color resist blocks 30 or within at least one color resist block 30, and the color of the first dimming color resist block 40 is different from the color of the color resist block 30 where it is located.

[0049] It should be noted that in this application, the substrate can be a color film substrate provided with a color filter layer. The transparent substrate 10 can use a glass material substrate to avoid affecting the light transmittance of the substrate. The black matrix 20 is a light-shielding layer that plays a role in light shielding. However, since there are open areas on the black matrix partition 20, light leakage is likely to occur. The material of the black matrix 20 is a highly conductive black light-shielding material, and specifically, black metals (such as iron, chromium, etc.), or black resins with high conductivity, or ordinary black resins doped with silver nanowires and carbon nanotubes can be selected. Generally, the layer where all the color resistors are located is called the color resistor layer, and the color resistor layer can be used to block the passage of light of different colors. The color resistor layer specifically includes a red color resistor block, a green color resistor block, and a blue color resistor block, and the red color resistor block, the green color resistor block, and the blue color resistor block are arranged at intervals in their respective corresponding open areas.

[0050] It can be understood that the first dimming color resistor block 40 is a color resistor layer used to adjust the light transmittance of the color resistor layer. The color of the first dimming color resistor block 40 is not the same as the color of the color resistor block 30 to be set, otherwise the effect of reducing the light transmittance of the color resistor block 30 cannot be achieved. For example, when it is necessary to reduce the light transmittance of the red color resistor block, the color of the first color resistor dimming layer 40 can be selected as the reverse color blue, the intermediate color green, or white.

[0051] In addition, in order to avoid causing too large a change in the overall color resistance of the color resistor block 30, when the color of the first color resistor adjustment layer 40 is the reverse color or the intermediate color, the size of the first color resistor adjustment layer 40 cannot be greater than half of the size of the color resistor block 30 where it is located. For example, when it is necessary to reduce the light transmittance of the red color resistor block, the first color resistor dimming layer 40 is blue or green, and when the size of the first color resistor dimming layer 40 is greater than half of the size of the red color resistor block, the red color resistor block will become a blue color resistor block or a green color resistor block.

[0052] In Figure 1 this, the first dimming color resistor block 40 can be set on the corresponding color resistor block 30 according to the specific color deviation of the display panel. Of course, considering that setting the first dimming color resistor block 40 on the color resistor block 30 will have a certain impact on the overall thickness of the display panel. Therefore, referring to Figure 2 in this application, the first dimming color resistor block 40 can also be set inside the corresponding color resistor block 30. For example, by removing part of the structure on the color resistor block 30 to form a slot, and then filling the slot with the first dimming color resistor block 40, the display chromaticity can be adjusted without changing the substrate.

[0053] When adjusting the color of the display panel, the position of the first dimming color resistance block 40 can be determined according to the color deviation of the display panel. For example, when the color currently displayed on the display panel is yellowish, the first color resistance adjustment layer 40 can be set on the red color resistance block, thereby reducing the light transmittance of the entire red color resistance block and shifting the display effect of the display panel towards the blue direction. Of course, when the color currently displayed on the display panel is bluish, the first color resistance adjustment layer 40 can be set on the blue color resistance block to reduce the light transmittance of the entire blue color resistance block.

[0054] It should be emphasized that green is the intermediate color between red and blue. When the color currently displayed on the display panel is greenish, the color of the first color resistance adjustment layer 40 can be determined according to the specific needs of the user. If the user hopes to make the current display chromaticity of the display panel yellowish, the first color resistance adjustment layer 40 with the color of red can be set on the green color resistance block, thereby increasing the light transmittance of yellow light in the green color resistance block and adjusting the display chromaticity towards the yellowish side; similarly, if the user hopes to make the current display chromaticity of the display panel bluish, the first color resistance adjustment layer 40 with the color of blue can be set on the green color resistance block.

[0055] Therefore, without considering the intermediate colors green and white, when the first dimming color resistance block 40 is on the red color resistance block, the color of the first dimming color resistance block 40 should be blue; when the first dimming color resistance block 40 is on the blue color resistance block, the color of the first dimming color resistance block 40 should be red; when the first dimming color resistance block 40 is on the green color resistance block, the color of the first dimming color resistance block 40 should be one of red or blue.

[0056] In the first embodiment of the present invention, a substrate is provided. The substrate includes: a transparent substrate and a black matrix provided on the transparent substrate. The black matrix is provided with a plurality of spaced-apart opening areas. The color resistance layer is provided in the opening areas and corresponds to the opening areas one by one. The color resistance layer includes: a red color resistance block, a green color resistance block, and a blue color resistance block; the substrate further includes: a first dimming color resistance block; the first dimming color resistance block is provided on the red color resistance block, the green color resistance block, or the blue color resistance block, and the color of the first dimming color resistance block is different from the color of the color resistance block where it is located. In the first embodiment, by setting the first dimming color resistance block with a color different from that of the color resistance block on the color resistance block, the light transmittance of the color resistance layer can be adjusted without changing the aperture ratio of the color resistance layer, effectively solving the problem of color deviation in the display chromaticity.

[0057] Embodiment Two

[0058] Referring to Figure 4 , Figure 4 is a schematic structural diagram of the substrate in the second embodiment of the present invention. Based on the first embodiment of the above substrate, the second embodiment of the substrate of the present invention is proposed.

[0059] In Embodiment 2, the color filter layer includes: a red color filter block, a green color filter block, and a blue color filter block, and the substrate further includes: a second dimming color filter block 50;

[0060] When the first dimming color filter block 40 is disposed on the red color filter block or the blue color filter block, the second dimming color filter block 50 is disposed on the green color filter block.

[0061] It should be understood that after the first dimming color filter block 40 is disposed, there may still be a certain degree of color deviation in the display panel. For example, the color deviation of the display panel is relatively serious or the size requirement of the first dimming color filter block 40 is large. At this time, the second dimming color filter block 50 can be disposed on the green color filter block to further adjust the color patches of the display panel.

[0062] Refer to Figure 4 and Figure 5 , where the second dimming color filter block 50 is disposed on the green color filter block, and the size of the second dimming color filter block 50 can be determined according to specific dimming requirements. The color of the second dimming color filter block 50 can be the same as the color of the first dimming color filter block 40. For example, in Figure 5 , if the color of the first dimming color filter block 40 disposed on the red color filter block is blue, the color of the second dimming color filter block 50 can also be blue; of course, when the color of the first dimming color filter block 40 is red, the color of the second dimming color filter block 50 can also be red.

[0063] Refer to Figure 6 , in Embodiment 2, when the sizes of the respective color filter blocks 30 are inconsistent, the display color deviation of the display panel can also be adjusted by setting the first dimming color filter block 40 and the second dimming color filter block 50. For the specific adjustment process, reference can be made to the method of adjusting when the sizes of the respective color filter blocks 30 are the same, and details are not described here.

[0064] Refer to Figure 7 , further, in Embodiment 2, the first dimming color filter 40 and / or the second dimming color filter block 50 each include: at least one sub-dimming color filter block, and the color of the sub-dimming color filter block is the same as the color of the dimming color filter block where it is located. It can be understood that the first color filter dimming layer 40 or the second color filter dimming layer is set as a plurality of sub-structures of the same color. In Figure 7 , the first color filter dimming layer 40 includes two sub-dimming color filter blocks, and the second color filter dimming layer 50 includes three sub-dimming color filter blocks. However, in Embodiment 2, the specific number of sub-dimming color filter blocks is not limited and can be set according to actual needs.

[0065] In addition, during the color display process of the display panel, there may be regional liquid crystal disorder in some areas of the liquid crystal layer, resulting in black state light leakage when the display panel displays an image, reducing the black state brightness of the module, and thus increasing the contrast. The area where the liquid crystal state changes, that is, the area where liquid crystal disorder occurs, is the liquid crystal domain state area A.

[0066] Refer to Figure 8 , in which due to liquid crystal disorder in the liquid crystal domain state area A, there are areas with corners in the color resistor block 30. In this liquid crystal domain state area A, due to liquid crystal disorder, black state light leakage occurs in the display panel.

[0067] Considering that the color resistor dimming layer in this solution will block some areas on the color resistor block 30 where it is located, thus realizing the dimming process. Therefore, when setting the color resistor dimming layer, the sub-color resistor dimming layer can be set in the projection area of the liquid crystal domain state area A of the liquid crystal layer on the color resistor block 30, that is, the projection of each sub-dimming color resistor block on the liquid crystal layer is within the liquid crystal domain state area, achieving the effect of reducing black state light leakage. Refer to Figure 9 , in Figure 9 , some liquid crystal domain state areas A in the liquid crystal layer are blocked by the sub-dimming color resistor blocks. When setting each sub-dimming color resistor block, the sub-dimming color resistor block can be preferentially set in the projection area of the liquid crystal domain state area A on the chromaticity layer, which can not only adjust the display chromaticity of the display panel, but also block the liquid crystal domain state area to avoid black state light leakage of the display panel, thus achieving the dual functions of increasing the contrast and adjusting the chromaticity.

[0068] In Figure 8 , the projection of the liquid crystal domain state area on the color resistor block 30 is in the four peripheral edge area of the color resistor block 30 and the connection area of the midpoints of the long sides of the color resistor block 30. Refer to Figure 10 and Figure 11 , in the case of a large number of sub-dimming color resistor blocks, sub-dimming color resistor blocks can be set in the projection areas of all liquid crystal domain state areas A on the color resistor block 30, so as to further reduce the liquid crystal domain state area A, and thus further reduce the black state light leakage phenomenon. In Figure 10 , the projection areas of all liquid crystal domain state areas A in the red color resistor block are blocked by the sub-dimming color resistor blocks. At this time, the black state light leakage phenomenon corresponding to the R color resistor is very low. In Figure 11 , the projection areas of all liquid crystal domain state areas A in the red color resistor block and the green color resistor block are blocked by the sub-dimming color resistor blocks. Similarly, the black state light leakage phenomenon corresponding to the red color resistor block and the green color resistor block is very low.

[0069] In addition, considering that most of the projections of the liquid crystal domain regions A are located around the color resist blocks, when setting the sub-dimming color resist blocks, it is preferable to start setting the sub-dimming color resist blocks from the peripheral edge regions of the color resist block 30, that is, the sub-dimming color resist blocks are set in contact with the black matrix 20.

[0070] When the sub-dimming color resist blocks are set in contact with the black matrix, the effect of reducing light leakage in the black state is the most obvious. Therefore, in the situation of considering reducing the light leakage in the black state to the lowest level, the sub-dimming color resist blocks can be set in contact with the black matrix 20.

[0071] In the second embodiment, by dividing the first dimming color resist block 40 and the second dimming color resist block 50 into multiple sub-dimming color resist blocks and setting each sub-dimming color resist block within the projection area of the liquid crystal domain region A on the corresponding color resist block, when adjusting the display chromaticity of the display panel, the liquid crystal domain region can also be blocked to avoid light leakage in the black state of the display panel, thereby reducing the black state brightness of the module and further improving the contrast.

[0072] In the color resist dimming layer of this solution, a part of the area on the color resist block 30 where it is located will be blocked, thereby realizing the dimming process. When setting the color resist dimming layer, the sub-color resist dimming layer can be set in other defective areas on the display panel, and blocking this defective area can further improve the display effect.

[0073] It can be understood that during the normal display process of the display panel, when there may be uneven display in some areas, the position corresponding to this position on the color resist block 30 can be marked, and then the sub-dimming color resist blocks are set at the positions corresponding to the uneven display areas on the color resist block 30. For example, in the case where the uneven display of the display panel is caused by the uneven color resist area of the color resist block 30, each of the sub-dimming color resist blocks can be set within the uneven color resist area.

[0074] Of course, if the uneven display is caused by some structures on the array board or the liquid crystal layer, then sub-dimming color resist blocks are set at the corresponding positions of the liquid crystal layer or the array board on the color resist block 30.

[0075] In the second embodiment, the substrate further includes a protective layer 60;

[0076] The protective layer 60 is disposed on the upper surface of the transparent substrate 10 including the black matrix 20, the color resist layer, and the first dimming color resist block 40.

[0077] It should be understood that the protective layer 60 is used to protect the black matrix 20, the color resist layer, and the first dimming color resist block 40 on the transparent substrate 10 from being affected by the external environment and causing an impact on the performance of the substrate. The material of this protective layer 30 is a light-sensitive material.

[0078] In Embodiment 2, for different color shift situations of the display panel, the first dimming color resistance block 40 and the second dimming color resistance block 50 are set for the above different situations.

[0079] When the chromaticity of the liquid crystal display panel is yellowish, a blue first dimming color resistance block 40 can be added to the red color resistance block, so that the color of the liquid crystal display panel shifts towards the blue direction, thereby achieving chromaticity adjustment.

[0080] Of course, a blue second dimming color resistance block 50 can also be added to the green color resistance block at the same time to achieve blue shift of the R chromaticity and the G chromaticity.

[0081] And the first dimming color resistance block 40 and the second dimming color resistance block 50 can be set in the projection area of the liquid crystal domain region A on the color resistance block 30, and can also shield the light leakage in the black state of the liquid crystal domain region A, thereby improving the contrast.

[0082] For chromaticity adjustment, according to the chromaticity adjustment requirements, the shape, size and position of the blue first dimming color resistance block 40 and the second dimming color resistance block 50 can be designed and optimized in the corresponding color resistance block 30, so as to obtain the best solution for chromaticity adjustment and contrast improvement.

[0083] In addition, if the chromaticity of the entire liquid crystal display panel is uneven, the shape, size and position of the first dimming color resistance block 40 and the second dimming color resistance block 50 can be designed and optimized in the uneven area in the color resistance block 30, so as to obtain the best solution for chromaticity adjustment and contrast improvement.

[0084] When the chromaticity of the liquid crystal display panel is bluish, a red first dimming color resistance block 40 can be added to the blue color resistance block, so that the color of the liquid crystal display panel shifts towards the red direction, thereby achieving chromaticity adjustment.

[0085] Of course, a red second dimming color resistance block 50 can also be added to the green color resistance block at the same time to achieve yellow shift of the R chromaticity and the G chromaticity, and the first dimming color resistance block 40 and the second dimming color resistance block 50 can be set in the projection area of the liquid crystal domain region A on the color resistance block 30, and can also shield the light leakage in the black state of the liquid crystal domain region A, thereby improving the contrast.

[0086] For chromaticity adjustment, according to the chromaticity adjustment requirements, the shape, size and position of the red first dimming color resistance block 40 and the second dimming color resistance block 50 can be designed and optimized in the corresponding color resistance block 30, so as to obtain the best solution for chromaticity adjustment and contrast improvement.

[0087] In addition, when the chromaticity of the entire liquid crystal display panel is uneven, the shape, size, and position of the first dimming color resistor block 40 and the second dimming color resistor block 50 can be optimized within the uneven area of the color resistor block 30, so as to obtain the best solution for chromaticity adjustment and contrast improvement.

[0088] If the chromaticity of the liquid crystal display panel is greenish, a red first dimming color resistor block 40 can be added to the green color resistor block, so that the color of the liquid crystal display panel shifts towards yellow, or a blue first dimming color resistor block can be added to the green color resistor block, so that the color of the liquid crystal display panel shifts towards blue, thereby realizing chromaticity adjustment. The color of the first dimming color resistor block can be set according to user needs.

[0089] When it is necessary to shift the display chromaticity from greenish to yellow, a red first dimming color resistor block 40 can be added to the blue color resistor block and a red second dimming color resistor block 45 can be added to the green color resistor block at the same time to further shift the display chromaticity towards yellow. Similarly, further shifting towards blue can be achieved and will not be elaborated here.

[0090] Of course, when the first dimming color resistor block 40 is separately provided on the green color resistor block, the first dimming color resistor block 40 can be provided within the projection area of the liquid crystal domain state area A on the green color resistor block. When the first dimming color resistor block 40 and the second dimming color resistor block 50 are respectively provided on two color resistor blocks, the first dimming color resistor block 40 and the second dimming color resistor block 50 can also be respectively provided within the projection areas of the liquid crystal domain state areas A in their respective corresponding color resistor blocks on the color resistor block 30, thereby improving the contrast.

[0091] For chromaticity adjustment, according to the chromaticity adjustment requirements, the shape, size, and position of the red or blue first dimming color resistor block 40 can be optimized within the green color resistor block; when the first dimming color resistor block 40 and the second dimming color resistor block 50 are respectively provided in two color resistor blocks, the shape, size, and position of the first dimming color resistor block 40 and the second dimming color resistor block 50 are optimized within the corresponding color resistor block 30, so as to obtain the best solution for chromaticity adjustment and contrast improvement.

[0092] In addition, when the chromaticity of the entire liquid crystal display panel is uneven, the shape, size, and position of the first dimming color resistor block 40 and the second dimming color resistor block 50 can be optimized within the uneven area of the color resistor block 30, so as to obtain the best solution for chromaticity adjustment and contrast improvement.
