Method used for liquid crystal dripping

Abstract

The invention discloses a method used for liquid crystal dripping. In the method used for dripping liquid crystal to a substrate, liquid crystal is introduced into a liquid crystal supply path, and is made to drip through a nozzle via injecting gas to liquid crystal forming liquid crystal drops at a nozzle end part, the method comprises steps of: repetitively supplying a preset amount of liquid crystal to the liquid crystal supply path; and supplying gas required by the liquid crystal dripping from the nozzle end part, thereby making the liquid crystal drip.

Description

technical field [0001] The present invention generally relates to a liquid crystal dispenser, and more particularly to a method for dripping liquid crystals onto a substrate. Background technique [0002] Generally, a liquid crystal display (LCD) includes a lower substrate, an upper substrate, a sealant, and a liquid crystal layer. The lower substrate has drive devices, such as transistors, on the flat glass. The upper substrate has a color filter layer on the flat glass. A sealant is used to attach the upper and lower substrates to each other. A liquid crystal layer is filled between the upper substrate and the lower substrate. Such an LCD drives liquid crystal molecules in a liquid crystal layer through a driving device formed on a lower substrate, and controls the intensity of light passing through the liquid crystal layer by driving the liquid crystal molecules, thereby displaying information. [0003] According to an LCD manufacturing method, a driving device is for...

AI Technical Summary

Problems solved by technology

The difference in thickness of the liquid crystal layer makes the path of light passing through the liquid crystal layer different, which in turn causes spots on the screen of the product and causes defective products
