Problems solved by technology

[0004] However, the injection time of the existing liquid crystal injection method is too long, so it cannot be applied to large-size panels
Furthermore, the equipment used in the ODF method is too expensive and the manufacturing process is complicated, and when the liquid crystal dropping amount (about 0.5 mg ~ 1.5 mg) is inaccurate, problems such as air bubbles or uneven coating are likely to occur

Abstract

The invention provides a liquid crystal coating device and a liquid crystal coating method. The liquid crystal coating device comprises a liquid crystal coating component, a real-time detector and a controller. The liquid crystal coating method comprises the following steps of: coating a liquid crystal onto a substrate by using the liquid crystal coating component; detecting the liquid crystal coated onto the substrate in real time by using the real-time detector, and outputting a detection signal; and controlling the liquid crystal coating component according to the detection signal by usingthe controller. By the liquid crystal coating device and the liquid crystal coating method, liquid crystal coating situations can be monitored in real time, and uniform liquid crystal films can be coated and formed.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal coating device and a liquid crystal coating method, in particular to a liquid crystal coating device and a liquid crystal coating method capable of real-time monitoring of liquid crystal coating conditions and coating to form a uniform liquid crystal film . 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. [0003] A liquid crystal display panel is composed of two transparent substrates and a liquid crystal sealed between the substrates. During the assembly process of the liquid crystal display panel, the liquid crystal is filled and sealed between the transparent substrates. At present, the existing methods for filling the liquid crystal between the transparent substrates are the liquid crystal injection method (vacuum s...
