Embodiments of the present invention provide an alignment device and an alignment method thereof, which relate to the technical field of liquid crystal displays, solve the problem of difficult alignment of non-rectangular polarizers in the existing alignment process of polarizers, and reduce the The alignment difficulty of the non-rectangular polarizer is reduced, the alignment accuracy of the polarizer is improved, and the performance of the display device is guaranteed. It includes: an angle adjustment device; the angle adjustment device is set to: adjust the angle of the polarizer to be aligned according to the angular offset of the polarizer to be aligned in the plane where the polarizer to be aligned is located. The invention is applied in the alignment technology of polarizers.
Description
technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to an alignment device and an alignment method thereof. Background technique [0002] The working principle of Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is to use electric field to control the state of liquid crystal molecules, so as to control whether the light generated by the backlight can pass through the liquid crystal molecules, thereby passing through the color filter Each film layer, in order to achieve the color pattern effect on the display screen. This requires alignment of the polarizer when attaching the polarizer in the module process of the TFT-LCD manufacturing process. [0003] In the existing automatic attaching process of polarizers, it is relatively easy to realize the alignment of polarizers with a rectangular shape. For the attachment of circular, regular polygonal polarizers and other shapes, one solution is to achieve it by manual...
