Abstract

The invention discloses a linear polarization ultraviolet lamp which comprises a base, a polarizer, a first roller and a second roller. The polarizer comprises a fixed end and a movable end far away from the fixed end, the fixed end is fixedly connected to the base, the movable end is connected onto the base and moves relative to the base through the first roller and the second roller, the first roller is mounted on the base and connected with the movable end in a rolling manner, or the first roller is mounted at the movable end and connected with the base in a rolling manner, the second roller is mounted on the base and connected with the movable end in a rolling manner, or the second roller is mounted at the movable end and connected with the base in a rolling manner. The polarizer can be optionally extended after heating expansion, instability of linear polarization ultraviolet light outputted by the linear polarization ultraviolet lamp caused by bending of the polarizer is avoided, the optical alignment quality of a liquid crystal display is improved, the quality of an alignment film is improved, and the yield of the liquid crystal display is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a linearly polarized ultraviolet light lamp. Background technique [0002] With the continuous improvement of display technology, the use of liquid crystal displays in display devices has become more and more extensive, and various display manufacturers have invested in research on the production and manufacturing technology of liquid crystal displays. In the production process of liquid crystal cells, it is first necessary to coat a polyimide (Polyimide, PI) solution on the glass substrate, and then use linearly polarized ultraviolet light (UV) to irradiate. During the irradiation process, PI molecules undergo a chemical reaction to form Alignment film, so that the liquid crystal molecules can be arranged in an orderly manner under the molecular force of the alignment film. How to obtain stable linearly polarized ultraviolet light to complete the photoalignment task has become...
