Abstract

An apparatus for coating polyimide layer includes a print table, an inkjet head, and a polyimide liquid supply tank, wherein the inkjet head is configured to jet the polyimide liquid in a scan-coating and be shifted by a predetermined shift pitch in a direction until 2N times of scan-coating occurs in which N>=2 and N is a natural number. A method for coating polyimide layer includes placing a substrate, loading a polyimide liquid vessel into a polyimide liquid supply tank, jetting the polyimide liquid onto the substrate in a scan-coating, repeating the jetting the polyimide liquid onto the substrate in a scan-coating and the shifting the inkjet head by a predetermined shift pitch until 2N times of scan-coating occurs in which N>=2 and N is a natural number.

Description

technical field [0001] The present invention relates to an apparatus and method for applying a polyimide layer, and more particularly to an apparatus and method for applying a polyimide layer by an inkjet coating method. Background technique [0002] A liquid crystal display (LCD) device is a device that displays a desired image by adjusting the amount of light reaching a color filter substrate by changing The intermolecular alignment of the liquid crystal material achieves the electric constant. A typical liquid crystal display device is a thin film transistor liquid crystal display (TFT LCD) device using a thin film transistor (TFT) as a switching element. [0003] Generally, such an LCD device includes an LCD panel for displaying images and a driver for driving the LCD panel by applying a driving signal to the LCD panel, and the LCD panel includes a color filter substrate and an array substrate bonded to each other at a predetermined distance and a clip The liquid cryst...
