Abstract

The invention provides dimming glass and a glass module, and belongs to the technical field of display glass. The dimming glass comprises a basic dimming structure and a reflective polarizer; the basic dimming structure comprises a first substrate, a second substrate and a first liquid crystal layer, wherein the first substrate and the second substrate are oppositely arranged, and the first liquid crystal layer is arranged between the first substrate and the second substrate; the first liquid crystal layer is used for overturning under the control of an electric field generated between the first substrate and the second substrate so as to control the transmittance of light; the reflective polarizer is located on the side, away from the liquid crystal layer, of the first substrate.

Description

technical field [0001] The invention belongs to the technical field of display glass, and in particular relates to a dimming glass and a glass module. Background technique [0002] At present, dimming glass is more and more widely used in the fields of construction and transportation, and customers such as automobiles, high-speed rail, and airliners are interested in dye liquid crystal dimming glass. In the existing smart glass market, there are products such as PDLC smart glass and electrochromic smart glass. PDLC smart glass can only switch between transparency and haze, without shading or heat insulation; electrochromic smart glass has problems such as complex coating process, slow response time (8-20s), and bluish dark color. Dye liquid crystal dimming glass utilizes the selective absorption of light by dichroic dye molecules in liquid crystals to switch between bright and dark states. Optical performance has been greatly improved. However, the existing dye liquid cry...
