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

A polarizer splicing method comprises the following steps: providing a substrate (1); sticking a first polarizer (2) on the substrate (1); sticking a second polarizer (3) on the substrate (1) to ensure that the side part (30) of the second polarizer (3) is correspondingly superposed with the side part (20) of the first polarizer (2); cutting the superposed part between the first polarizer (2) and the second polarizer (3) correspondingly; removing the cut parts separated from the first polarizer (2) and the second polarizer (3); and carrying out a planarizing process on the cut side parts of the first polarizer (2) and the second polarizer (3).

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...
