Liquid crystal infusion device

Abstract

The invention discloses a liquid crystal infusion device, comprising a liquid crystal bottle, a filter and a pump, wherein the filter is connected between the liquid crystal bottle and the pump through a liquid transport pipe; the liquid crystal bottle is used for storing liquid crystal; the pump is used for pumping the liquid crystal and infusion the liquid crystal onto a substrate. The liquid crystal infusion device further comprises an air exhaust pipe, wherein one end of the air exhaust pipe extends into the filter; the other end of the air exhaust pipe extends into the liquid crystal bottle, and is positioned above the liquid crystal in the liquid crystal bottle; the air exhaust pipe is used for exhausting bubbles which enter into the filter. According to the liquid crystal infusion device, the bubbles can be prevented from entering into the filter, and the filter can be prevented from being blocked by the bubbles.

Description

technical field [0001] The invention relates to a liquid crystal dripping device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is undoubtedly a mainstream product in modern display devices. The general components of a TFT-LCD are a thin film transistor substrate (TFT substrate), a color filter substrate (CF substrate), and a liquid crystal material interposed between the Array substrate and the CF substrate. The main working principle of TFT-LCD is: the liquid crystal material between the TFT substrate and the CF substrate is loaded by an appropriate voltage, so that the liquid crystal molecules are deflected under the action of the voltage, and different transmittances are obtained through different voltage control, thus realizing show. [0003] The traditional liquid crystal injection method has been eliminated (the TFT substrate and the CF substrate are assembled first, and then the liquid crystal is sucked in by capillary phenomen...

AI Technical Summary

Problems solved by technology

Since the current liquid crystal bottle moves with the machine, during the movement process, there will be very small air bubbles in the liquid crystal bottle, and the air bubbles will enter the filter membrane area of ​​the filter, resulting in the following two problems:

[0005] 1. The liquid level in the membrane area drops, and the utilization rate of the membrane decreases

[0006] 2. Bubbles with a pore size of 0.1um or larger enter the filter membrane pores of 0.1um, causing the filter membrane to be blocked, and the filter loses its filtering ability and is scrapped

Disruption of liquid crystal dripping causes the substrate to be scrapped
