[0025] Currently, for black-and-white liquid crystal display screens, when color display is required, it is achieved by adding a color film at the bottom of the display screen. That is, when the liquid crystal display panel is lit, the color of the light transmitted from the bottom will show the corresponding color pattern on the front, rather than a simple black-and-white picture. Usually, the outer shape of the color blocks silk-screened on the color film is larger than the outer shape of the actual display pattern of the liquid crystal display screen to ensure that the corresponding pattern area can still be completely covered even when the color film is offset. However, when different color patterns are relatively close to each other and the space is narrow, different color blocks will be close to each other, resulting in color bleeding problems when the color film is slightly offset.
[0026] In view of the above problems, the embodiment of this application provides an attaching structure for a color film of a liquid crystal display module, which can improve the attaching accuracy of the color film and prevent color bleeding problems of the display screen.
[0027] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0028] Please refer to Figures 1 to 3, An attaching structure for a color film of a liquid crystal display module, comprising: a substrate 100 and a color film 200. The substrate 100 includes a first glass plate body 110 and a second glass plate body 120. The first glass plate body 110 is disposed on the second glass plate body 120. Between the first glass plate body 110 and the second glass plate body 120, a first identification position 111, a second identification position 112, and a third identification position 113 are provided; on the color film 200, a first alignment mark 210, a second alignment mark 220, and a third alignment mark 230 are provided. The first alignment mark 210 is used to be flush with the first identification position 111, the second alignment mark 220 is used to be flush with the second identification position 112, and the third alignment mark 230 is used to be flush with the third identification position 113.
[0029] It should be noted that the first identification position 111, the second identification position 112, and the third identification position 113 are patterns formed by SEG traces and COM traces on the first glass plate body 110 and the second glass plate body 120 respectively, and the first identification position 111, the second identification position 112, and the third identification position 113 are not on the same straight line, and the connection lines of the three form a triangle. Similarly, the connection lines of the first alignment mark 210, the second alignment mark 220, and the third alignment mark 230 form a triangle in sequence. Further, when attaching the color film 200, light up the display screen, and then align the first alignment mark 210, the second alignment mark 220, and the third alignment mark 230 with the first identification position 111, the second identification position 112, and the third identification position 113 respectively one by one. Through the three-point positioning principle, the attaching accuracy of the color film 200 can be improved, and the problem of display screen color bleeding can be prevented.
[0030] Please refer to Figure 2 and Figure 3 , In an embodiment, the cross-sectional structure of the first identification position 111 is the same as the cross-sectional structure of the first alignment mark 210. Specifically, the cross-sectional structure of the second identification position 112 is the same as the cross-sectional structure of the second alignment mark 220. Specifically, the cross-sectional structure of the third identification position 113 is the same as the cross-sectional structure of the third alignment mark 230. Specifically, the first identification position 111, the second identification position 112, and the third identification position 113 all have a circular cross-sectional structure.
[0031] It should be noted that the first identification position 111, the second identification position 112, and the third identification position 113 are all dot-shaped, the first alignment mark 210, the second alignment mark 220, and the third alignment mark 230 are all circular rings. The inner diameter of the circular rings is 1.5 mm, and the outer diameter is 2.2 mm. The circular rings are printed in gray and are nested and aligned with the dots during alignment. At the same time, the circular rings and other patterns are printed by the same silk screen, and the positional tolerance between the patterns is very small. Therefore, as long as it is determined that these three dots are aligned, the accuracy of other patterns is guaranteed. While improving color bleeding, the efficiency of attaching the color film 200 can be greatly improved.
[0032] Please refer to Figure 2 and Figure 3 , in an embodiment, a first graphic area 114 is provided between the first glass plate body 110 and the second glass plate body 120, a second graphic area 240 is formed on the color film 200, and the first graphic area 114 and the second graphic area 240 are parallel to each other. Specifically, a third graphic area 121 is provided between the first glass plate body 110 and the second glass plate body 120, a fourth graphic area 250 is formed on the color film 200, and the third graphic area 121 and the fourth graphic area 250 are parallel to each other.
[0033] It should be understood that the first glass plate body 110 is conducted through SEG traces, and the second glass plate body 120 is conducted through COM traces. As Figure 2 shown, if the character OFF needs to be lit, the corresponding SEG traces and COM traces need to be conducted so that a voltage difference is formed after they are conducted up and down. The liquid crystal of the ITO between the two overlapping glass plate bodies will flip, and then the light can pass through to show the display pattern of OFF. For the part where the graphics between the two glass plate bodies do not overlap, no upper and lower voltage difference is formed, the liquid crystal will not flip, and the light cannot pass through.
[0034] That is, the first graphic area 114 and the third graphic area 121 are formed by conducting and lighting the two glass plate bodies. Both the first graphic area 114 and the third graphic area 121 can have multiple ones.
[0035] It should also be noted that the graphic area of the color film 200 needs to be expanded, so the area of its graphic area is slightly larger than that of the graphic area on the glass plate body.
[0036] Please refer to Figure 1 , in an embodiment, the substrate 100 further includes a first polarizer 130, and the first polarizer 130 is disposed on the first glass plate body 110. Specifically, the substrate 100 further includes a second polarizer 140, the second polarizer 140 is disposed on the second glass plate body 120, and the color film 200 is disposed on the second polarizer 140.
[0037] It should be noted that both the first polarizer 130 and the second polarizer 140 are transparent to facilitate the alignment and attachment of the color film 200.
