Vapor etching alignment method and vapor etching alignment equipment

Abstract

The invention relates to vapor etching alignment equipment. The vapor etching alignment equipment is characterized by comprising a platform, a spray gun, a high-pressure vapor spraying system and a movement system, wherein the platform is used for carrying a glass substrate, the spray gun is arranged above the platform, the high-pressure vapor spraying system is used for providing high-pressure vapor flow for the spray gun, and the movement system is used for driving the platform or the spray gun to do relative movement. The invention also provides a vapor etching alignment method using the vapor etching alignment equipment. The vapor etching alignment method comprises the following steps of aligning the spray gun with an alignment film, and adjusting an included angle between the spray gun and the alignment film to a preset angle theta; starting the high-pressure vapor spraying system, adjusting the vapor pressure, and performing vapor etching when the vapor pressure is greater than the vapor etching critical value x. The vapor etching alignment equipment and the vapor etching alignment method have the advantages that the direct contact with the alignment film is avoided, the generation of micro particles, static electricity and scratches at the surface of the alignment film are effectively avoided, the obtained vapor etching grooves are regular, and the alignment of liquid crystals is favorably controlled.

Description

technical field [0001] The invention relates to the field of alignment film processing in the production process of liquid crystal display screens, in particular to the method and equipment used for alignment by air engraving. Background technique [0002] In the production process of liquid crystal display, the quality of alignment film processing also determines the quality of the display. Such as figure 1 As shown, in the previous Rubbing (rubbing) alignment technology, rubbing cloth 1 (rubbing cloth) and alignment film 2 will inevitably produce particle 3 (particles), static electricity 4 and scratches 5 after rubbing, which greatly affects the glass. The quality of the panel, in order to eliminate the impact of the above factors, this paper proposes a non-contact alignment method - air etching alignment method and the special equipment used. Due to the non-contact alignment method, on the one hand, this alignment method can effectively avoid the generation of static e...
