Abstract

The invention provides a manufacturing method for a curved surface display. The curved surface display comprises color filter glass, thin film transistor glass, first curved surface glass and second curved surface glass. The manufacturing method comprises the following steps: pasting the first curved surface glass to the thin film transistor glass to form a first assembly; pasting the second curved surface glass to the color filter glass to form a second assembly; pairing and vacuumizing the first assembly and the second assembly; pouring liquid crystal layers between the first assembly and the second assembly to form the curved surface display. Compared with the prior art, for the method, the thin film transistor glass and the color filter glass are independently bent into the appearance curvatures of the curved surface glass to respectively form the first assembly and the second assembly. After the thin film transistor glass and the color filter glass are paired, the curvatures of the thin film transistor glass and the color filter glass are pulled by the corresponding curved surface glass, so that the gaps between the liquid crystal layers can be effectively maintained, and therefore, the color deviation phenomenon of the curved surface display is improved.

Example Embodiment

[0033] In a specific embodiment, the manufacturing method further includes: bending the thin film transistor glass 102 in advance so that the curved surface after bending corresponds to the curvature of the first curved surface glass 100. The color filter glass 202 is bent in advance so that the curved surface after bending corresponds to the shape curvature of the second curved glass 200. Preferably, the respective curvatures of the first curved glass 100 and the second curved glass 200 are equal.

[0034] In a specific embodiment, the manufacturing method further includes: before forming the first assembly A1, first thinning the thin film transistor glass 102, and then attaching the first polarizer to the thin film transistor glass 102 surface. In addition, before forming the second assembly A2, the color filter glass 202 may be thinned first, and then a second polarizer can be attached to the surface of the thinned color filter glass 202.

[0036] Reference image 3 , Figure 4A~4D In this embodiment, when the first assembly A1 is formed, step S111 is first performed to apply a patterned adhesive 104 (such as a rectangular bend) on the curved inner surface (such as Figure 4C ). Then step S113 is performed to apply a sealant 103 on the surface of the thin film transistor glass 102 (such as Figure 4B ), wherein the sealant 103 is used for bonding and pairing the first component A1 and the second component A2. Finally, in step S115, the first curved glass 100 is pasted to the thin film transistor glass 102 (such as Figure 4D ). Preferably, before steps S111 to S115, steps B1 and B3 can be performed to thin the thin film transistor glass 102, and then the first polarizer 101 is attached to the thin film transistor glass 102 surface ( Such as Figure 4A ).

[0038] Reference Figure 5 , Figure 6A~6D In this embodiment, when the second assembly A2 is formed, step S131 is first performed to coat a back glue 204 on the curved outer surface of the second curved glass 200 (such as Figure 6C ). Then, step S133 is performed to paste the second curved glass 200 to the color filter glass 202 (such as Figure 6D ). Preferably, before steps S131 to S133, steps C1 and C3 can be performed to thin the color filter glass 202, and then attach the second polarizer 201 to the thinned thin film transistor glass 202 Surface (e.g. Figure 6A with Figure 6B ).

[0039] Using the curved display manufacturing method of the present invention, the first curved glass is pasted to the thin film transistor glass to form the first component, and the second curved glass is pasted to the color filter glass to form the second component, and then the above two The components are grouped and vacuumed, and the liquid crystal layer is poured between the two components to form a curved display. Compared with the prior art, in the present invention, the thin film transistor glass and the color filter glass are individually bent into the shape curvature of the curved glass to form the first component and the second component respectively, and then the pairing is performed. At this time, the thin film transistor glass The curvature of the color filter glass is pulled by the corresponding curved glass, so that the gap between the liquid crystal layer between the thin film transistor glass and the color filter glass can be effectively maintained, thereby improving the color deviation of the curved display.
