Abstract

The invention provides a method for confirming liquid droplets are not dropped and a liquid crystal coating machine for implementing the method. The method includes a first step for transmitting the signal to the coating head unit and spraying the liquid crystal droplets from the nozzle of the coating head unit; a second step for storing the data of the position positioned by the nozzle disposed on the coating heat unit when a first detection unit disposed on the coating head unit does not detect the liquid crystal droplet dropped from the nozzle to the target point on the panel area; a thirdstep for moving a second detection unit of the coating head unit to the position by the stored data after completion of dropping in one panel are or the number of liquid crystal droplets needed by themotherboard; a forth step for taking image of the target point on the panel area by the second detection unit positioned at the position; and a fifth step for confirming of no liquid crystal dropletdrop by the image taken by the second detection unit.

Description

Technical field [0001] The present invention relates to a method for confirming that LC (liquid crystal) droplets are not dripping, and an LC coater for implementing the method. Background technique [0002] Liquid crystal is an intermediate state between a crystalline solid state and an isotropic liquid state, and combines certain characteristic properties of a crystal structure with certain characteristic properties of a deformable fluid. LCD (liquid crystal display) utilizes the fluidity of its liquid crystal and the anisotropy related to its crystal characteristics. The application of LCD can be seen in portable phones, portable computers, desktop monitors and LCD TVs. The LCD includes a TFT (thin film transistor) array substrate, a color filter array substrate, and a liquid crystal layer sandwiched between them. By controlling the voltage applied to the liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts, thus forming different gray ...
