Alignment film precuring equipment

Abstract

The invention discloses an orientation membrane pre-curing equipment, comprising a workbench and a heater arranged above the workbench; the heater is an infrared generating device which comprises a plurality of quartz glass far infrared ray heating tubes; wherein, a moving device is connected below the workbench and can drive the workbench to move up and down relative to the heater. The invention arranges the heating device on the upper part of the equipment and uses the infrared generating device to generate infrared so as to achieve panel heating to a substrate which has no contact with the heating device; the substrate has an air layer in the middle and can be evenly heated; besides, the workbench can move up and down; when the heating starts, the workbench has a longer distance from the infrared generating device on the upper part of the equipment, so the substrate is heated by less heat; during the heating process, the workbench automatically rises and is more and more close to the infrared generating device on the upper part of the equipment, so the substrate is heated by more and more heat so as to achieve a gradual increase in heating temperature to reduce the rate of unqualified products caused by uneven heating and improve the product yield.

Description

technical field

[0001] The invention relates to a manufacturing device of a liquid crystal display, in particular to a pre-curing device for an alignment film of a liquid crystal display. Background technique

[0002] In recent years, with the popularization of digital TV, the traditional CRT display has tended to be replaced by a new generation of display technology due to its difficulty in digitization, large size, heavy weight, and radiation. The representative new display technology is PDP, OLED, LCD, etc. Among them, liquid crystal display (LCD) has begun to be widely popularized due to its advantages of light weight, thin volume, no radiation, low power consumption, and high display resolution, and has become a mainstream product.

[0003] At present, liquid crystal displays are developing in the direction of full color, large size, and high resolution. The alignment film pre-curing equipment is to heat the substrate at medium and low temperature after the alignment ...
