Display device based on phase-change material

Abstract

The invention discloses a display device based on a phase-change material. The display device comprises a series of pixel points, and each pixel point comprises a reflecting layer deposited on a substrate, an isolating layer deposited on the reflecting layer, a solid-state phase-change layer deposited on the isolating layer and a covering layer deposited on the solid-state phase-change layer; the reflecting layers have the reflectivity of 80% or above in the visible light range and are used for supplying back reflection; the isolating layers are used for adjusting the reflectivity of the whole device; the solid-state phase-change layers can be reversibly transformed between a crystalline state and a noncrystalline state under driving of voltage or lasers to cause changes of the reflectivity of the phase-change materials, so that the colors of all the pixel points change; the covering layers are used for receiving the externally-exerted voltage. A large number of the pixel points can be stacked to form a display array through the spatial structure.

Description

technical field [0001] The invention belongs to the field of display devices, and more specifically relates to a display device based on phase-change materials. Background technique [0002] There have been many dramatic advances in display technology, such as portable computers and communication devices. Some of these display technologies, such as backlit color displays, are power-intensive and difficult to fabricate. While other technologies can provide black-and-white displays without a backlight, they are slow to respond, so unsuitable for displaying video, and lack color displays. And these techniques are difficult to generate high-resolution images. Contents of the invention [0003] Aiming at the defects of the prior art, the object of the present invention is to provide a display device based on phase-change materials. Most of the display devices of the prior art are low-molecular liquid crystals, whose molecules are 2nm to 3nm in length and about 0.5nm in diamet...
