Problems solved by technology

The current auto-dimming polarized LCD sunglass lenses are made of 6-point viewing direction, and the angle between the polarization angle and the horizontal plane is 45 degrees, which does not meet the requirements of the sunglass industry for 0-degree polarization, and the shading area is narrow, which does not meet the requirements. ,like figure 1 shown
[0003] Or, in order to meet the requirement of 0-degree polarized light, only 4:30 viewing direction and 7:30 viewing direction can be made. The problem is that the shading area of ​​polarized LCD sun lenses is no longer dark at the top and shallow at the bottom, but presents an inner figure. The inclined shading area, and the shading area is narrow, see the attached figure 2 , which also does not meet the requirements of polarized liquid crystal sun lenses

Abstract

The invention discloses a 0-degree polarized liquid crystal sunglasses lens. Through visual direction adjustment, box structure adjustment, polaroid selection, polaroid angle, polaroid optical axis and visual direction matching and external driving voltage matching, 0-degree polarization is achieved, the shading area of the polarized liquid crystal sunglasses lens is widened, and the liquid crystal sunglasses lens meeting the requirement for 0-degree polarization is manufactured.

Description

technical field [0001] The invention relates to a 0-degree polarized liquid crystal sun lens. Background technique [0002] With the development of liquid crystal display technology, liquid crystal display screens are applied to the field of automatic dimming polarized sunglasses. The current auto-dimming polarized LCD sunglasses lenses are made of 6-point viewing direction, and the angle between the polarization angle and the horizontal plane is 45 degrees, which does not meet the requirements of the sunglass industry for 0-degree polarization, and the shading area is narrow, which does not meet the requirements. ,Such as figure 1 shown. [0003] Or, in order to meet the requirement of 0-degree polarized light, only 4:30 viewing direction and 7:30 viewing direction can be made. The problem is that the shading area of ​​polarized liquid crystal sun lenses is no longer dark at the top and shallow at the bottom, but presents an inner figure. The inclined shading area, and t...
