Problems solved by technology

The moving time of the shading plate of the existing G8.5 generation production line is about 5s. Combining the two actions of opening and closing, the central point takes about 10s more irradiation time than the two side edges, which leads to the existence of pre-tilt angles between the two side edges and the center point. Inconsistencies, which affect the optical performance o

Abstract

The invention relates to the field of LCD displayer manufacturing, and discloses an illumination assembly used for controlling the illumination time of lamp tubes on a substrate in an ultraviolet light illuminating machine in the ultraviolet light aligning working process. The illumination assembly includes multiple shading plates, and at least one end of each shading plate is connected with a driving device for controlling; when the shading plates are arranged, each shading plate has an independent axis, and by overturning the shading plates around the corresponding lamp tubes, the switch-onand switch-off states of each lamp tube can be achieved. Each shading plate can be overturned to a first position and a second position, and therefore it is ensured that the ultraviolet illumination time of each area of the substrate is equal, the illumination uniformity is controlled, and uniform pretilt angles can be maintained on liquid crystals.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacture, in particular to an ultraviolet light alignment process. Background technique [0002] The ultraviolet light alignment process is a technology in the cell-to-cell manufacturing process of LCD displays. By irradiating ultraviolet light to the substrate, the reactive monomers in the liquid crystal react, so that the liquid crystal forms a pre-tilt angle. The size of the pretilt angle and the exposure time are in direct proportion. The longer the time, the larger the pretilt angle. Lighting time needs to be strictly controlled. [0003] The UV alignment process needs to use a UV liquid crystal irradiation machine to emit ultraviolet light. At present, metal halide lamps, mercury lamps and fluorescent lamps are commonly used. In actual production, these lamps use the shape of lamp tubes arranged side by side to irradiate the substrate, and the time for each substrate to be irradiat...
