Abstract

The invention relates to a device and a method for attaching a polarizing plate. In the invention, the device for attaching the polarizing plate in one embodiment comprises a rolling device and a shifting platform, wherein the rolling device attaches the polarizing plate to a panel; and the shifting platform is arranged on the front side of the rolling device and shifts the polarizing plate to the rolling device. The shifting platform includes a platform sliding plate and a front end sorption member, and the front end sorption member is closer to the rolling device than the shifting platform. The included angle between the polarizing plate and the panel is adjusted and set by the platform sliding plate and the front end sorption member of the shifting platform. In a process of attaching the polarizing plate, the rolling device and the shifting platform are heated. In one embodiment, the temperature of the shifting platform is set to be between 35 and 65 DEG C; and the temperature of the rolling device is set to be between 35 and 65 DEG C. Therefore, the internal stress or warping stress of the polarizing plate can be eliminated and the probability of the occurrence of air bubbles after the polarizing plate is attached to the panel is lowered greatly.

Description

[0001] This application is a divisional application of an invention patent application whose applicant is AU Optronics Co., Ltd., with an application date of October 29, 2008, an application number of 200810173838.5, and an invention title of "Polarizer Attaching Device and Method". technical field [0002] The invention relates to a polarizing plate attaching device and method, in particular to the manufacture of liquid crystal display panels. Background technique [0003] Liquid crystal displays are now widely used in electronic products with growth potential such as monitors, notebook computers, digital cameras, and projectors. In the manufacturing process of liquid crystal display panels, the circuits of the display panels need to be fabricated on glass substrates through multiple processes. . [0004] figure 1 It shows a schematic diagram of a conventional polarizing plate attaching device 10 of a liquid crystal display, in which the polarizing plate 11 is carried and ...
