[0032] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments.
[0033] Figure 1 is a schematic structural diagram of a liquid crystal display panel according to the first embodiment of the present application; as Figure 1 shown, as the first embodiment of the present application, a liquid crystal display panel 100 is disclosed. The liquid crystal display panel 100 includes a display panel main body 101, and a color resist layer 122 and a light-shielding film layer 140 for reducing the light transmittance provided in the display panel main body 101. The color resist layer 122 and the light-shielding film layer 140 are sequentially provided in the light-emitting direction of the display panel main body 101. The color resist layer 122 includes a red color resist layer 123, a green color resist layer 124, and a blue color resist layer 125. The light-shielding film layer 140 is provided corresponding to the red color resist layer 123 and the green color resist layer 124, and the light-shielding film layer 140 is not provided corresponding to the blue color resist layer 125.
[0034] Considering that the transmittance of blue light is lower than that of red light and green light, in the general light mixing stage, the proportion of red light and green light in the total amount of red, green, and blue light is relatively large, resulting in the mixed light being yellowish, thus affecting the display effect. In this application, a color resist layer 122 and a light-shielding film layer 140 for reducing the light transmittance are sequentially arranged in the light-emitting direction of the liquid crystal display panel 100. That is, in the light-emitting direction of the liquid crystal display panel, the color resist layer 122 is in the front, and the light-shielding film layer 140 is arranged behind the color resist layer 122. The light-shielding film layer 140 is arranged corresponding to the red color resist layer 123 and the green color resist layer 124, and the light-shielding film layer 140 is not arranged corresponding to the blue color resist layer 125. By reducing the transmittance of red light and green light through the light-shielding film layer 140, the proportion of blue light, red light, and green light is close in the light mixing stage, thus avoiding the color being yellowish after light mixing due to the large difference in the proportion of blue light, red light, and green light, and thus affecting the display effect.
[0035] The display panel main body 101 includes a first substrate 110, a second substrate 120, and a liquid crystal layer 130 disposed between the first substrate 110 and the second substrate 120. The second substrate 120 is a color filter substrate, the first substrate 110 is an array substrate, the second substrate 120 includes a substrate 121, the color resist layer 122 is formed on the substrate 121, a polarizer 150 is provided on the side of the color filter substrate away from the array substrate, and the light-shielding film layer 140 is disposed between the polarizer 150 and the second substrate 120. By disposing the light-shielding film layer 140 between the polarizer 150 and the color filter substrate, the installation of the light-shielding film layer 140 can be realized more quickly. Of course, the light-shielding film layer 140 can also be embedded in the color filter substrate, as long as it is disposed in any layer on the side of the color resist layer away from the first substrate.
[0036] In addition, it should be noted that if the first substrate 110 is a COA substrate (i.e., color filter on array, the color resist layer is disposed on the array substrate), the COA substrate includes a substrate and a color resist layer formed on the substrate, and the second substrate 120 is a substrate without a color resist layer, then the light-shielding film layer can be disposed in any layer on the side of the color resist layer on the COA substrate away from the substrate of the COA substrate. For example, it can be disposed in the liquid crystal layer (such as attached to the side of the substrate of the second substrate close to the COA, or attached to any film layer of the COA substrate away from the color resist layer in the COA substrate), or it can be disposed in the second substrate 120. Of course, it can also be disposed between the second substrate 120 and the polarizer 150, and the appropriate position can be selected according to the light transmittance that needs to be reduced actually.
[0037] As the second embodiment of this application, taking the first substrate as the array substrate and the second substrate as the color filter substrate for refinement and improvement, as Figure 2As shown, the liquid crystal display panel 100 includes a display area 200 and a non-display area 300. The non-display area 300 is disposed around the display area 200. The display area 200 includes a first area 210 and a second area 220 disposed on one side of the first area 210 along the gravity direction. When the liquid crystal display panel 100 is placed vertically, the first area 210 is on the top and the second area 220 is on the bottom. The light-shielding film layer 140 is correspondingly disposed in the second area 220. In the direction of the polarizer 150 facing the color resist layer 122, the projected area of the light-shielding film layer 140 on the first substrate 110 is less than or equal to the sum of the projected areas of the red color resist layer 123 and the green color resist layer 124 on the first substrate 110.
[0038] The light-shielding film layer 140 is mainly disposed in the second area 220 of the display area 200. The liquid crystal is likely to gather and fall in the second area 220. After the fallen liquid crystal gathers, the cell thickness at the gathering place increases. Since the penetration ability of blue light is weak, when the cell thickness increases, the blue light will decrease. In the color mixing stage, the proportion of red light and green light is relatively large, resulting in a yellowish color. Since the light-shielding film layer 140 is provided corresponding to the red color resist layer 123 and the green color resist layer 124 in the second area 220, the light-shielding film layer 140 also weakens the red light and the green light, making the light of red, green, and blue colors more uniform and avoiding the problem of yellowish color after color mixing. For the setting of the light-shielding film layer 140, it can be laid as a whole layer between the polarizer 150 and the second substrate 120, and hollowed out at the position corresponding to the blue color resist layer 125. Of course, it can also be set only corresponding to the red color resist layer 123 and the green color resist layer 124. It should be noted that the projected area of the light-shielding film layer 140 on the first substrate 110 is less than or equal to the sum of the projected areas of the red color resist layer 123 and the green color resist layer 124 on the first substrate 110, that is, the transmittance of partial areas of the red color resist layer 123 and the green color resist layer 124 is weakened, or the transmittance of all areas corresponding to the entire red color resist layer 123 and the green color resist layer 124 can be weakened. In addition, if there is a gap between the red color resist layer 123 and the green color resist layer 124 and the blue color resist layer 125, the projected area of the light-shielding film layer 140 on the first substrate 110 can be greater than the sum of the projected areas of the red color resist layer 123 and the green color resist layer 124 on the first substrate 110, and the projection of the light-shielding film layer 140 on the first substrate 110 just covers the projections of the red color resist layer 123 and the green color resist layer 124 and the gap between the red color resist layer 123 and the green color resist layer 124 and the blue color resist layer 125 on the first substrate 110.
[0039] Such as Figure 3As shown, as the third embodiment of the present application, it is a further refinement of the above-mentioned second embodiment. The light-shielding film layer 140 includes a plurality of sub-light-shielding portions 141. The red color-resist layer 123 includes a plurality of red color-resists distributed in an array, and the green color-resist layer 124 includes a plurality of green color-resists distributed in an array. Each sub-light-shielding portion 141 is provided corresponding to one red color-resist or one green color-resist; each sub-light-shielding portion 141 is arranged at intervals, and the light transmittance of all the sub-light-shielding portions 141 corresponding to the same row of color-resists is the same; the sub-light-shielding portions 141 of the light-shielding film layer 140 are provided corresponding to each color-resist, accurately reducing the light transmittance of each color-resist, reducing the interference of the light at the color-resist junction on the light of the directly facing color-resist, accurately controlling the light transmittance of each color-resist, and improving the fineness of the display screen.
[0040] The sub-light-shielding portion 141 can usually be a whole, made of a carbon black or manganese ferrite black material doped with a transparent glass layer, facing the red color-resist and green color-resist in the second region 220, and can effectively absorb part of the red light and green light, so that the red light and green light are reduced, and then kept uniform with the relatively weak blue light passing through, avoiding the color from turning yellow after light mixing. Of course, the sub-light-shielding portion 141 can also not be a whole, such as Figure 4 As shown, but is formed by combining a transparent region 142 and a light-shielding region 143. The transparent region 142 and the light-shielding region 143 are arranged at intervals to form a louvered structure, and the image quality is adjusted by changing the width of the louvers. When the red light and green light pass through the sub-light-shielding portion 141, the light-shielding region 143 absorbs part of the red light or green light, so that the red light or green light is weakened, while the transparent region 142 does not absorb the red light or green light and has a relatively small influence on the red light or green light. For the whole sub-light-shielding portion 141, the red light or green light is reduced, so that the light mixed in the light mixing stage will not turn yellow. The light-shielding region 143 and the transparent region 142 arranged at intervals can make the light of the color-resist form an obvious contrast and have a clear boundary, which is also beneficial to improving the quality of the display screen.
[0041] Such as Figure 5 As shown, as the fourth embodiment of the present application, it is a further improvement of the above-mentioned third embodiment. The second region 220 includes a first sub-region 221 and a second sub-region 222 provided on one side of the first sub-region 221 along the gravity direction; the sub-light-shielding portion 141 is provided in the first sub-region 221, and the sub-light-shielding portion 141 may not be provided in the second sub-region 222; in the first sub-region 221, along the gravity direction, the width of the transparent region 142 gradually decreases, the width of the light-shielding region 143 gradually increases, and the absolute value of the difference between the width of the transparent region 142 and the width of the light-shielding region 143 gradually increases; Figure 5The width of the transparent region 142 of the first row sub-light-shielding portion 141 in the first sub-region 221 is the largest compared to other rows, and the width of the transparent region 142 of the last row sub-light-shielding portion 141 is the smallest compared to other rows. The lengths of the transparent region 142 and the light-shielding region 143 are the same.
[0042] Considering the influence of gravity or high temperature, the liquid crystal may sag, and it is likely to accumulate in the area 5 cm from the bottom of the liquid crystal display panel 100, that is, within the first sub-region 221. Within the first sub-region 221, the number of liquid crystals accumulating from top to bottom increases in sequence. That is to say, more liquid crystals accumulate near the second sub-region 222 in the first sub-region 221, resulting in a greater cell thickness here. Then the blue light here will be weaker. To avoid the problem of yellowish color, the corresponding sub-light-shielding portion 141 here needs to absorb more red light and green light. Therefore, within the first sub-region 221, along the direction of gravity, the width of the transparent region 142 gradually decreases, the width of the light-shielding region 143 gradually increases, and the absolute value of the difference between the width of the transparent region 142 and the width of the light-shielding region 143 gradually increases, so that the reduction amount of the overall red or green light transmittance of the sub-light-shielding portion 141 gradually increases, avoiding the problem of excessive color difference of the three-color light and yellowish color.
[0043] Furthermore, as Figure 6 shown, as the fifth embodiment of the present application, different from the above fourth embodiment, when the liquid crystal display panel 200 is placed vertically, within the first sub-region 221, the light transmittance of the sub-light-shielding portion 141 gradually decreases from both sides of the first sub-region 221 to the middle, and also gradually decreases from the side far from the second sub-region 222 to the side close to the second sub-region 222; a sub-light-shielding portion 141 can also be provided within the second sub-region 222, but the light transmittance of the sub-light-shielding portion 141 gradually decreases from both sides of the second sub-region 222 to the middle. Along the direction of gravity, from both sides to the middle, the width of the transparent region 142 in the sub-light-shielding portion 141 gradually decreases, the width of the light-shielding region 143 gradually increases, and the absolute value of the difference between the width of the transparent region 142 and the width of the light-shielding region 143 gradually increases, so that the reduction amount of the overall red or green light transmittance of the sub-light-shielding portion 141 gradually increases from both sides to the middle.
[0044] As the sixth embodiment of the present application, it is a further improvement of the above second embodiment or third embodiment or fourth embodiment or fifth embodiment. Refer to Figures 7 to 10As shown, the liquid crystal display panel includes a support frame 160. The support frame 160 includes a rectangular frame 161 and strip-shaped columns 162. The strip-shaped columns 162 are fixed within the rectangular frame 161 and are correspondingly disposed within the second region 220. A color resist trace 126 is disposed on the second substrate 120. The color resist trace 126 is connected to the color resist layer 122. The strip-shaped columns 162 are correspondingly disposed opposite the color resist trace 126. The sub-light-shielding portions 141 corresponding to the color resist in the same row are rotatably disposed on the strip-shaped columns 162.
[0045] The louver-shaped sub-light-shielding portion 141 is rotatably connected to the strip-shaped column 162. As Figure 9 shown, when the liquid crystal display panel 100 is placed flat, the sub-light-shielding portion 141 is parallel to the incident direction of the light from the backlight of the liquid crystal display panel. At this time, the sub-light-shielding portion 141 does not block any light and does not affect the transmittance of red light or green light. As Figure 10 shown, when the liquid crystal display panel 100 is placed obliquely, the sub-light-shielding portion 141 overlaps with the incident direction of the light from the backlight of the liquid crystal display panel. At this time, the sub-light-shielding portion 141 blocks red light or green light, and the light-shielding area 143 of the sub-light-shielding portion 141 absorbs red light or green light, thereby reducing the transmittance of red light or green light. When the liquid crystal display panel 100 is placed vertically, the sub-light-shielding portion 141 is perpendicular to the incident direction of the light from the backlight of the liquid crystal display panel. At this time, the sub-light-shielding portion 141 blocks red light or green light, and the light-shielding area 143 of the sub-light-shielding portion 141 absorbs red light or green light, thereby reducing the transmittance of red light or green light. To ensure that the louver-shaped sub-light-shielding portion 141 can rotate in different placement states of the liquid crystal display panel 100, along the direction of the polarizer 150 facing the second substrate 120, the thickness of the rectangular frame 161 is greater than the sum of the thicknesses of the strip-shaped column 162 and the sub-light-shielding portion 141, reserving sufficient space for the rotation of the sub-light-shielding portion 141.
[0046] Furthermore, as Figure 8As shown, the support frame 160 is provided corresponding to the entire display area 200. Generally, the support frame 160 is provided corresponding to the entire second substrate 120. Of course, it can also be provided corresponding to the entire polarizer 150. Here, the description is made with the support frame 160 provided corresponding to the entire second substrate 120. The second substrate 120 includes an edge area 127 and a middle area 128. The edge area 127 is disposed around the middle area 128. The rectangular frame 161 is provided corresponding to the edge area 127 of the second substrate 120. Along the direction of the polarizer 150 facing the second substrate 120, the non-display area 300 covers the edge area 127, and the polarizer 150 covers the rectangular frame 161, avoiding the situation that there is no support structure in the first area 210 and the existing gap causes the polarizer 150 to tilt towards the first area 210, which is likely to cause fragmentation. Providing the rectangular frame 161 corresponding to the entire second substrate 120 can make the polarizer 150 and the second substrate 120 more stable. The support frame 160 can also be provided corresponding to the second area 220. In the first area 210, other transparent materials can be used to fill the space between the polarizer 150 and the second substrate 120 to ensure the uniformity of the film layers in the liquid crystal display panel 100.
