An apparatus and a method for producing a pre-tilt angle in a liquid crystal panel are disclosed. The apparatus includes a sample stage for placing the liquid crystal panel, at least one ultraviolet (UV) light source for irradiating the liquid crystal panel so that a filler material in a liquid crystal layer rotated to a preset angle can be cured to form a pre-tilt angle, and A UV filtering sheet transmissive to UV rays with wavelengths of 320 nm to 380 nm disposed between the sample stage and the UV light source. By disposing the UV filtering sheet, the filler material in the liquid crystal layer can be quickly cured and a desirable pre-tilt angle can be formed. This shortens the time of UV irradiation, improves the efficiency of producing a pre-tilt angle in the liquid crystal panel and lowers the manufacturing cost of the liquid crystal panel.
An apparatus for producing a pre-tilt angle in a liquid crystal panel, comprising a sample stage and at least one ultraviolet (UV) light source, the sample stage being adapted to place the liquid crystal panel thereon, the UV light source is adapted to irradiate the liquid crystal panel so that a filler material in a liquid crystal layer that has been rotated to a preset angle is cured to form a pre-tilt angle, wherein a UV filtering sheet is disposed between the sample stage and the UV light source and is only transmissive to UV rays with wavelengths of 320 nm to 380 nm.
A sample stage, comprising a sample stage body for placing a liquid crystal panel thereon, wherein a UV filtering cover is disposed on the sample stage body and is only transmissive to UV rays with wavelengths of 320 nm to 380 nm, and a space formed by the sample stage body and the UV filtering cover is adapted to accommodate the liquid crystal panel therein.
A light source apparatus, comprising a UV luminescent lamp body and a protective cover disposed around the UV luminescent lamp body, wherein a UV filtering cover is connected with the protective cover and is only transmissive to UV rays with wavelengths of 320 nm to 380 nm, and the UV luminescent lamp body is disposed in a space formed by the protective cover and the UV filtering cover so that all UV rays received by an irradiated object are filtered by the UV filtering cover.
A method for producing a pre-tilt angle in a liquid crystal panel, comprising the following steps of:
