Car windshield adopting liquid crystal display technology

Abstract

The invention discloses a car windshield adopting a liquid crystal display technology, and particularly discloses a car windshield capable of adjusting transparency and improving driving safety. The car windshield is structurally characterized by comprising upper-layer glass, a common electrode, an upper polarizer, liquid crystal molecules, a three-primary-color color filter, a lower polarizer, a pixel electrode and lower-layer glass; the realization principle of the windshield is as follows: coating films on inner sides of the upper-layer glass and the lower-layer glass form the common electrode and the pixel electrode which are stacked together, the polarizers, the liquid crystal molecules and the three-primary-color color filter are mounted in an interlayer, the liquid crystal molecules are arranged regularly and are in the transparent state, driving voltage is applied to the common electrode and the pixel electrode, an electric field changes the arrangement direction of the liquid crystal molecules to shield light rays, so that the transparency of the windshield is controlled, when a color filter area corresponding to a certain pixel is controlled, the color of the windshield in the area can be changed, and when multiple pixel combinations are driven simultaneously, display graphs or character information can be produced.

Description

technical field [0001] The invention relates to an automobile windshield, in particular to an automobile windshield capable of adjusting transparency and improving driving safety. Background technique [0002] At present, known automobile windshields are usually laminated glass structures, and PVB films are bonded in the interlayer. However, this kind of automobile windshield has a fixed transparency. When driving a car through different light environments, it will cause discomfort to the driver's eyes, which will affect driving safety and increase the risk of traffic accidents. Contents of the invention [0003] In order to solve the deficiency of existing automobile windshields, the present invention provides an automobile windshield using liquid crystal display technology. In the light environment, the amount of light passing through is reduced, and in the weak light environment, the transparency is increased to improve the field of vision, so as to balance the driver'...
