Liquid crystal dripping device with temperature control

Abstract

The invention discloses a liquid crystal dripping device with temperature control. The liquid crystal dripping device is characterized in that temperature controllers are arranged in elements such as a liquid crystal container, a transport pipe or a liquid crystal dripping sprayer, to decrease the viscosity of the liquid crystal before dripping to a substrate, and decrease the impact force on an alignment film on the substrate when dripping to the substrate, so that the possible occurrence of uneven dripping figure display caused by the dripping of the liquid crystal is reduced.

Description

【Technical field】 [0001] The present invention relates to a temperature control system, in particular to a liquid crystal dropping device with temperature control. 【Background technique】 [0002] The liquid crystal injection method in the traditional liquid crystal panel manufacturing process uses the capillary principle to slowly inject liquid crystal between the two glass substrates that have been combined. The disadvantage of this method is that it is very time-consuming and wastes liquid crystal material. [0003] The aforementioned liquid crystal injection method has been gradually replaced by a One Drop Filling (ODF) technique. The dropping injection technique is to directly drop the liquid crystal on a glass substrate through a liquid crystal dropping device, and then combine it with another glass. This new technology can greatly save the time and material of liquid crystal injection. [0004] However, when making some liquid crystal panels aimed at aligning liquid ...

Problems solved by technology

[0004] However, when making some liquid crystal panels aimed at aligning liquid crystals to improve the viewing angle, when liquid crystals are dripped onto the alignment film on the substrate through the drop injection technology, the impact of the liquid crystal drops on the alignment film will often lead to the dripping pattern of the finished product. Shows the occurrence of Drop Mura Defect, and the current improvement methods, such as figure 1 As shown, by increasing the number of drops of liquid crystal 900 and reducing the amount of liquid crystal per drop at the same time, the phenomenon of uneven display of dropped graphics can be overcome

However, the degree of improvement of this method is limited, and increasing the number of drops of liquid crystals and reducing the amount of liquid crystals per drop will affect the operational accuracy of the liquid crystal dropping device and increase the process time of liquid crystal injection.
