Liquid crystal dropping device and liquid crystal drop injection method

Abstract

The invention relates to a liquid crystal dripping device and a liquid crystal dripping type injection method. The liquid crystal dripping device comprises a carrying platform, a dripping component and multiple measuring components, wherein the carrying platform is used for carrying a glass substrate, the dripping component can drip liquid crystal into multiple target areas on the glass substrate, and the multiple measuring components are arranged between the glass substrate and the carrying platform and used for measuring the weight of the glass substrate in each target area. By means of the dripping component, the dripping amount of the liquid crystal in each target area can be controlled through the weight measured by the measuring components, so that the liquid crystal amount in each target area is made to reach the standard amount. By means of the liquid crystal dripping device and the liquid crystal dripping type injection method, the dripping amount of the liquid crystal in the target areas can be controlled accurately, so that low-temperature bubbles are effectively prevented from appearing in a liquid crystal panel which is produced subsequently, and therefore it is guaranteed that the liquid crystal panel can be used normally.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal displays, and in particular relates to a liquid crystal dropping device and a liquid crystal dropping injection method. Background technique [0002] The liquid crystal panel of the liquid crystal display usually adopts a one drop filling method (one drop filling, ODF) to realize liquid crystal injection, and the main equipment for implementing the drop filling method is a liquid crystal dropping device (also called a liquid crystal dropping machine). The liquid crystal dropping device mainly includes an object-carrying platform for placing a glass substrate, and a dropping component for dropping liquid crystal into a target area on the glass substrate. [0003] The existing liquid crystal dropping device mainly controls the amount of liquid crystal dripping through the dripping syringe (also known as the dispensing head) of the dripping assembly. It is not accurate enough to determine the...

[0003] The existing liquid crystal dripping device mainly controls the amount of liquid crystal dripping through the dripping syringe (also known as the dispensing head) of the dripping assembly. It is not accurate enough to determine the drop volume (such as quality) of liquid crystal in the target area by the number of drops of liquid crystal dropped by the liquid drop syringe, so that low-temperature air bubbles are prone to appear in the liquid crystal panel produced in the later stage, thus affecting the use of the liquid crystal panel
