Abstract

The invention discloses a liquid crystal suction device. The device comprises a first vacuum generating unit, a flexible suction pipe and a load body, wherein the load body is arranged at one end of the flexible suction pipe; and the other end of the flexible suction pipe is connected with the first vacuum generating unit. The invention further discloses liquid crystal coating equipment. In this way, the invention can ensure that the suction end of a liquid crystal pipeline is kept below the liquid crystal level all the time so as to prevent the suction end of the liquid crystal pipeline from sucking air bubbles.

Description

technical field [0001] The invention relates to the technical field of liquid crystals, in particular to a liquid crystal absorption device and liquid crystal coating equipment. Background technique [0002] A liquid crystal display device (LCD) includes a thin film transistor (TFT) array substrate, a color filter array substrate, and a liquid crystal layer sandwiched therebetween. A liquid crystal display device (LCD) produces an image by controlling a voltage applied to a liquid crystal layer within each pixel and thereby allowing light to transmit in varying amounts. [0003] The formation of the liquid crystal layer is mostly achieved by liquid crystal coating. Liquid crystal coating is to apply a certain amount of liquid crystal to each panel area defined on a (TFT) array substrate or a color filter array substrate in the form of a plurality of liquid crystal droplets corresponding to a reference amount of liquid crystal. Usually, a liquid crystal dropping machine is ...
