Problems solved by technology

Among them, light with a wavelength of less than 320nm can cause monomer polymerization to occur in the liquid crystal material. The speed of monomer polymerization is proportional to the intensity of the light wave. The stronger the light wave, the faster the polymerization speed of the liquid crystal monomer. The polymerization of the liquid crystal monomer will cause the LCD screen Broken bright spots are generated, which leads to poor manufacture of LCD panels

Abstract

The invention discloses an irradiation machine for liquid crystal alignment. The irradiation machine comprises a UV lamp tube and a first filtering cover covering the UV lamp tube, wherein the first filtering cover is used for absorbing light rays with the wavelength of less than 320nm. According to the irradiation machine for liquid crystal alignment disclosed by the invention, the intensity of light waves can be greatly weakened, and the polymerization speed of a liquid crystal medium monomer is further reduced, so that the problem that broken bright spots occur on a liquid crystal layer in the process of performing alignment on liquid crystal when the irradiation machine irradiates on a liquid crystal display panel is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display manufacture, in particular to an irradiation machine for liquid crystal alignment. Background technique [0002] In the manufacturing process of liquid crystal displays, it is necessary to use UV (ultraviolet) lamps to irradiate the liquid crystal panel to achieve the effect of liquid crystal alignment. UV lamps are usually metal halide lamps, see figure 1 , UV lamps emit different bands of the spectrum. Among them, light with a wavelength of less than 320nm can cause monomer polymerization to occur in the liquid crystal material. The speed of monomer polymerization is proportional to the intensity of the light wave. The stronger the light wave, the faster the polymerization speed of the liquid crystal monomer. The polymerization of the liquid crystal monomer will cause the LCD screen Broken bright spots are generated, resulting in defective manufacture of liquid crystal panels. ...
