Abstract

The invention relates to a device for jointing a polarizer sheet to a liquid crystal display panel, comprising a polarizer sheet fixed platform, for supporting the polarizer sheet sticked with a protective film on at least one side; a main body of the device, arranged on the polarizer sheet fixed platform, moving along one surface of the polarizer sheet fixed platform; and at least a film removing unit combined with the main body of the device, including a pushing piece of a sticking belt for pushing the protective film to remove from the polarizer sheet and at least a bending roller spaced with the pushing piece, wherein the sticking belt is wound on the pushing piece and the bending roller and enclosed around the pushing piece in a sharp angle, to form a closed loop. Accordingly, the rising of the service life of the film removing unit adds the exchange working period of the film removing unit, thereby reducing the processing time and the flow error caused by the polarizer sheet in the flow of removing the protective film.

Description

technical field [0001] The present invention relates to a laminating equipment, in particular to a method of peeling off a protective film from at least one side of a polarizer, and then bonding the polarizer after peeling off the protective film to a liquid crystal display panel. device of. Background technique [0002] In the semiconductor industry, flat panel display (FDP) has shown rapid growth and development among electronic displays. [0003] The flat panel display is an image display device, and is lighter and thinner than the cathode ray tubes (CRT) generally used in televisions or computers. For example, the flat panel display includes a liquid crystal display, a plasma display panel (PDP), an organic light emitting diode (OLED), and the like. [0004] A thin film transistor liquid crystal display (thin film transistor LCD, TFT-LCD), which belongs to one of the flat panel displays, uses a light switching phenomenon. Here, in the photoswitching phenomenon, liquid...
