Problems solved by technology

[0041] Since the user controls the distance between the substrate 401 and the nozzle 402 by manually manipulating the micrometer 406, the reliability is greatly reduced, and the output rate of the liquid crystal display panel is reduced.
[0042] In addition, even for a skilled user, it takes a lot of time to precisely set the distance between the substrate 401 and the nozzle 402, which reduces productivity.
[0043] Furthermore, in the background technology, the spacing is set manually by the user, which is inconvenient to operate the equipment

Abstract

The dispenser of the liquid crystal display panel is configured by including a syringe which is furnished with the nozzle at one end and is isolated from the substrate, a vertical driving motor which drives the syringe to a vertical direction, a contact type switch which detects contactability or not of the nozzle and the substrate by driving the motor, and a first sensor which detects the initial value to contact the nozzle and the substrate by the result of detection of the contact type switch.

Description

[0001] This application claims the benefit of Korean Patent Application No. P2002-069768 filed on November 11, 2002, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a liquid crystal display panel, in particular, to a dispenser for manufacturing a liquid crystal display panel and a method for controlling the distance between a nozzle and a substrate using the dispenser. Background technique [0003] A liquid crystal display panel is a display device in which data signals including image signals are respectively supplied to liquid crystal cells arranged in a matrix form, and desired images are displayed by controlling the transmittance of the liquid crystal cells. Accordingly, a liquid crystal display device includes a liquid crystal display panel and a driver integrated circuit (IC) that drives liquid crystal cells. Liquid crystal cells are arranged in a matrix in unit pixels. [0004] The liquid crystal di...
