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

An apparatus and a method for coating liquid crystal are provided. The liquid crystal coating apparatus includes a liquid crystal coating module, a real-time detector and a controller. The liquid crystal coating method includes following steps: coating liquid crystal on the substrate by the liquid crystal coating module, detecting the liquid crystal coated on the substrate by the real-time detector, outputting detecting signals to the controller and controlling the liquid crystal coating module by the controller according to the detecting signals. The invention enables real-time monitoring of the liquid crystal coating operation and coating even liquid crystal film.

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 liquid crystal displays are backlight type liquid crystal displays, 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 th...
