Abstract

The invention discloses a liquid crystal injection method, comprising the following steps of: step a, closing the cabin door of a liquid crystal injection machine when a liquid crystal container is filled with liquid crystal, and then implementing step b, wherein the liquid crystal container is arranged on a base within a cavity of the liquid crystal injection machine, the liquid crystal container is equipped, in an insertion manner, with a liquid crystal heater controlled by an electric control system and a liquid crystal temperature controller which is used for feeding back liquid crystal temperature collected in real time to the electric control system to form a closed loop control; step b, removing air from the liquid crystal, then opening the cabin door and implementing step c; and step c, placing a roasted display panel on a bracket which is arranged within the cavity, and then closing the cabin door to complete the steps for injecting liquid crystal into the display panel. The liquid crystal injection method provided by the invention has the advantages that the heating structure of the liquid crystal container is simple and practical, the temperature of the liquid crystal can be accurately monitored, the viscosity of the liquid crystal is reduced to the largest extent while preventing the volatilization of low-boiling point component in the liquid crystal, and the consumption of the liquid crystal and the rejection rate of the product are reduced.

Description

technical field [0001] The invention relates to a method for injecting liquid crystals into glass empty boxes used in the production of liquid crystal displays. The liquid crystal injection method involved in the invention is mainly used in the injection process of ordinary low-viscosity liquid crystals, especially for some high-viscosity liquid crystals , and the injection process of ordinary low-viscosity liquid crystals under the condition of low ambient temperature. Background technique [0002] Liquid crystal display (LCD) is a kind of electronic device that achieves the purpose of controlling the light passing through the liquid crystal layer by controlling the rotation of liquid crystal molecules in an electric field, and finally realizes graphic display under the synergy of polarizing plates. The structure of the liquid crystal display mainly includes two glass substrates with transparent electrodes engraved on the surface, an alignment film coated on the top of the ...
