TP structure of curved liquid crystal module

Abstract

The utility model provides a TP structure of a curved-surface liquid crystal module, which solves the problems that the conventional liquid crystal glass basically takes a standard module as a carrier, two ends of the conventional liquid crystal glass are fixed with screw holes in the side edges of the standard liquid crystal module through L-shaped sheet metal parts, and then are locked and attached with mortise columns on the short edges of the inner side of a front frame with a TP, so that the TP structure is difficult to deform. And finally, the whole assembly of the liquid crystal glass is completed after the rear cover is assembled, and the assembly process is relatively complex, and can be widely applied to the field of liquid crystal display modules. The device specifically comprises a back plate, and a middle frame is installed on the back plate. Liquid crystal glass is installed on the middle frame, a curved TP cover plate is fixedly attached to the liquid crystal glass through OC glue, and the curved TP cover plate is matched with the liquid crystal glass in curvature. Notches are formed in the corners of the back plate, corner protection pieces are arranged in the notches in a matched mode, the corner protection pieces are made of rubber, and one side of each corner protection piece extends to the surface of the back plate.
