Method for setting pre-tilt angle of liquid crystal molecule

摘要

A method for setting a pre-tilt angle of liquid crystal molecules includes (1) providing liquid crystal material, a CF substrate, and a TFT substrate; (2) arranging the substrates to form a gap therebetween in which the liquid crystal material is filled to form a liquid crystal cell; (3) providing a drive control circuit that generates driving voltages and connecting the drive control circuit to the TFT substrate; (4) providing a small-amplitude oscillation device and an irradiation intensity variable ultraviolet light source and positioning the liquid crystal cell on the oscillation device; (5) activating the oscillation device to cause the liquid crystal cell to make small-amplitude oscillation and conducting on the drive control circuit to supply driving voltages to drive the liquid crystal material, the ultraviolet light source being applied to irradiate the liquid crystal cell with ultraviolet lights of different intensities; and (6) repeating step (5) for at least one time.

1. A method for setting a pre-tilt angle of liquid crystal molecules, comprising the following steps:
(1) providing a liquid crystal material, a CF substrate, and a TFT substrate; (2) arranging the CF substrate and the TFT substrate parallel with each other to form an accommodation gap therebetween and filling the liquid crystal material in the accommodation gap to form a liquid crystal cell; (3) providing a drive control circuit that generates a plurality of driving voltages and electrically connecting the drive control circuit to the TFT substrate; (4) providing a small-amplitude oscillation device and an irradiation intensity variable ultraviolet light source and positioning the liquid crystal cell on the small-amplitude oscillation device; (5) activating the small-amplitude oscillation device to cause the liquid crystal cell to make small-amplitude oscillation and conducting on the drive control circuit to supply a plurality of driving voltages to drive the liquid crystal material, wherein during this process, the ultraviolet light source is applied to irradiate the liquid crystal cell with ultraviolet lights of different intensities; and (6) repeating the operation of step (5) on the liquid crystal cell at least one time in order to complete setting of pre-tilt angle.
