Dimming plate, vehicle wind shield and vehicle

Abstract

The invention provides a dimming plate, a vehicle wind shield and a vehicle. The dimming plate comprises a first electrode layer, a middle electrode layer and a second electrode layer which are sequentially arranged at intervals along the normal of the dimming plate, wherein the first electrode layer and the second electrode layer are made of transparent materials; and a plurality of microcapsules which are embedded in the middle electrode layer, wherein the microcapsules protrude out of the two sides of the middle electrode layer and are located between the first electrode layer and the second electrode layer, charged particles are arranged in the microcapsules, and the microcapsules are made of transparent materials. According to the dimming plate provided by the invention, the microcapsules containing the charged particles are arranged, and the positions of the charged particles in the microcapsules can be controlled under the action of an electric field formed by the first electrode layer, the middle electrode layer and the second electrode layer, so that the light transmittance of the dimming plate is controlled, rapid switching of the light transmittance can be realized, and the control efficiency of the transmitted light is improved.

Description

technical field [0001] The invention relates to the technical field of optical engineering, in particular to a dimming board, a vehicle windshield and a vehicle. Background technique [0002] With the development of science and technology and the improvement of people's living standards, in the field of home life or vehicles, the control of ambient light has become a concern of people. The use of glass windows to adjust the size of transmitted light has gradually entered the market. How to control The accurate control of light transmittance has become an urgent research problem. [0003] At present, the schemes for adjusting the size of the transmitted light mainly include electrochromic glass. The electrochromic glass can undergo a reversible color change process under the action of an external electric field. However, the color switching process of this electrochromic glass is relatively slow. The control efficiency of the size of the transmitted light is low, and fast sw...
