Problems solved by technology

However, if air bubbles generated by vibration etc. caused during the operation of the LC coater are introduced into the liquid crystal discharge device, the LC coater may not be able to coat the liquid crystal at a preset position
In this case, a defective LCD

Abstract

The invention discloses a method for detecting faulty discharge of liquid crystal of an LC coater used in the LC coating process of the LCD manufacturing process. The invention can detect the faulty discharge of liquid crystal of the LC coater in advance, thereby preventing the production of defective LCD.

Description

technical field [0001] The present invention relates generally to a method for detecting mis-discharging of liquid crystals, and more particularly to a method for detecting mis-discharging of liquid crystals of an LC coater used during an LC coating operation of an LCD manufacturing process. Background technique [0002] An LCD (Liquid Crystal Display) is an image display device in which data signals are individually supplied to liquid crystal cells arranged in a matrix shape based on image information in order to control light transmittance of the liquid crystal cells, thereby displaying a desired image. [0003] Typically, an LCD includes a lower substrate provided with a driving device such as TFT (Thin Film Transistor), an upper substrate provided with color filters, and an LC layer formed by filling a space between the upper substrate and the lower substrate with liquid crystals. Accordingly, the manufacture of LCDs includes a process of forming an LC layer between an u...
