Abstract

The embodiment of the invention discloses a device for orientation of an air floating type liquid crystal substrate. The device comprises a heating platform, supports and supporting ejection needles, wherein a plurality of air holes are formed in the heating platform and used for delivering hot wind which is even in temperature and flows vertically upwards, the supports are arranged on the periphery of the heating platform and used for supporting and clamping the liquid crystal substrate to be oriented, the supporting ejection needles are evenly arranged in the heating platform, can move vertically with the supports in the same direction, and are used for supporting the bottom of the liquid crystal substrate for at least part time, and the air injection amount of the air holes is gradually reduced from the center of the heating platform to the edge of the heating platform. The embodiment of the invention further discloses a corresponding method for orientation. According to the device and method, the liquid crystal substrate is evenly heated and irradiated by ultraviolet light and the quality and the yield of the liquid crystal substrate can be improved.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display (Thin Film Transistor liquid crystal display, TFT-LCD) manufacturing technology, in particular to an alignment device and method for an air-floating liquid crystal substrate. Background technique [0002] Among the existing liquid crystal display manufacturing technologies, ultraviolet curing (UV Curing) is an important process. After the liquid crystal substrate is filled with liquid crystal mixture, it needs to complete the alignment process of liquid crystal under the combined action of ultraviolet light and electric field. [0003] The principle of alignment by ultraviolet curing is to apply an electric field on the upper and lower sides of the liquid crystal substrate, and irradiate the liquid crystal with ultraviolet light, so that the reactive monomers in the liquid crystal move up and down under the action of the electric field, and polymerize under the action of ultraviolet ...
