Document Type and Number:
WIPO Patent Application WO/2022/088152
Kind Code:
A1
Abstract:
A reflective display device, a display panel and a display screen. In the reflective display device, one side of a substrate (301) is provided with an antenna array (302), which is composed of a dielectric material array (3021) and an electrochromic material thin film (3022), and a control circuit (303) is connected to the electrochromic material thin film (3022) by means of a conductive material, so as to allow an electrical signal to control an electrochromic material, such that a change in a refractive index imaginary part of the electrochromic material thin film (3022) is controlled by means of the electrical signal, thereby changing the display brightness of a specific color. Thus, the display of different colors and brightness can be realized by means of antenna arrays (302) of different geometric sizes, and the display of various colors can be realized according to combinations of different colors and brightness.
