Method for manufacturing alignment films of liquid crystal panels

摘要

A method for manufacturing alignment films of liquid crystal panel includes the steps of: injecting a liquid crystal mixture containing liquid crystal molecules and liquid crystal reactive monomers to form a liquid crystal cell; placing the liquid crystal cell in a first reaction machine to subject the same to a voltage, ultraviolet radiation, and a temperature, so that the liquid crystal reactive monomers produce a polymerization reaction; moving the liquid crystal cell to a second reaction machine after a first preset time period in order to subject the same to a voltage and a temperature to continue the polymerization reaction, and forming alignment films on inner surfaces of a first substrate and a second substrate, respectively.

1. A method for manufacturing alignment films of liquid crystal panel, comprising the following steps:
injecting a liquid crystal mixture between a first substrate and a second substrate, and stacking them together to form a liquid crystal cell, the liquid crystal mixture comprising liquid crystal molecules and liquid crystal reactive monomers; placing the liquid crystal cell in a first reaction machine to subject the same to a voltage, ultraviolet irradiation, and a temperature provided by the first reaction machine, so as to generate a polymerization reaction for the liquid crystal reactive monomers, wherein the voltage provided by the first reaction machine is 7V to 50V, an illuminance of the ultraviolet irradiation is 0.05 to 120 mW/cm2, and the temperature is 25° C. to 80° C.; determining whether a duration that the liquid crystal cell is placed in the first reaction machine reaches a first preset time period; moving the liquid crystal cell from the first reaction machine to a second reaction machine if the first preset time period is reached, to subject the liquid crystal cell to another voltage and another temperature provided by the second reaction machine to continue the polymerization reaction of the liquid crystal reactive monomers, wherein the voltage provided by the second reaction machine is 1V to 50V, and the temperature is 10° C. to 100° C.; determining whether a duration that the liquid crystal cell is placed in the second reaction machine reaches a second preset time period; and moving the liquid crystal cell out of the second reaction machine if the second preset time period is reached, to form alignment films on inner surfaces of the first substrate and the second substrate, respectively.
