Problems solved by technology

However, the splicing accuracy of the existing polarizer splicing technology is limited (about 0.3 millimeters), and there will be a certain interval 800 between the two spliced ​​polarizers 80, 81, which will cause the liquid crystal display at this interval 800. Light leakage occurs, so that the pixels at the position corresponding to this interval of 800 cannot be displayed normally

Abstract

The invention discloses a polaroid splicing method. The method comprises the following steps of: providing a substrate; adhering a first polaroid to the substrate; adhering a second polaroid to the substrate to ensure that the side part of the second polaroid is correspondingly superposed with the side part of the first polaroid; correspondingly cutting the superposed part between the first polaroid and the second polaroid; removing cut parts which are separated from the first polaroid and the second polaroid; and performing planarization treatment on the side parts of the first polaroid and the second polaroid. By the method, distances among spliced polaroids can be effectively reduced, and the problem of light leakage of liquid crystal displays at the splicing positions of the polaroids is solved.

Description

【Technical field】 [0001] The invention relates to the manufacturing technology of liquid crystal displays, in particular to a method for splicing polarizers. 【Background technique】 [0002] Liquid crystal displays (LCDs) have been widely used in various electronic products. The current liquid crystal display mainly includes two transparent substrates, a liquid crystal layer disposed between the two substrates, and polarized films disposed on the outer surfaces of the two substrates. [0003] The aforementioned polarizer is an important part of the liquid crystal display. When the light passes through one of the polarizers, the light will become polarized light with the same polarization direction as the polarization axis of the polarizer. The liquid crystal molecules in the liquid crystal layer can be twisted under the control of an external electric field, thereby controlling whether the polarized light passes through another polarizer, so that the brightness of each pixe...
