Abstract

The invention discloses an exposure method and an exposure device thereof. The exposure method comprises the steps of: confirming the position of the point to be exposed in the area to be exposed; capturing the point to be exposed, and confirming that the point to be exposed is successfully captured; Adjust the light source to the appropriate position at the point to be exposed successfully; the exposure machine completes the exposure operation. The invention can reduce the takt time of the exposure machine and improve the alignment accuracy of the output products.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an exposure method and an exposure device thereof. Background technique [0002] With the development and progress of science and technology, liquid crystal displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. Most of the liquid crystal displays on the market are backlit liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules in two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant posi...
