Light energy writing device

Abstract

The invention discloses a light energy writing device comprising a flexible substrate, a transparent conductive layer, a composite layer, a conductive layer, a flexible substrate conductive layer anda hard object support layer, which are sequentially arranged, wherein the composite layer is composed of bistable cholesteric liquid crystal and cured polymer alternately arranged; the flexible substrate is located at the uppermost layer, and the flexible substrate is closely connected to the transparent conductive layer located in the second upper layer; the composite layer is set in the intermediate layer, and is upwardly bonded to the bottom surface of the transparent conductive layer, and downwardly bonded to the upper surface of the conductive layer; the lower surface of the conductive layer is closely connected to the conductive layer of the flexible substrate, and the lower surface of the conductive layer of the flexible substrate is bonded to the hard object support layer. The light energy blackboard provided by the invention can be written by any hard object, has high brightness and low energy consumption, is green and healthy and not easy to cause visual fatigue, can save a large amount of electric energy, has strong practicability, and is worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a light energy writing device. Background technique [0002] The traditional teaching blackboard will produce a lot of dust, which seriously endangers the health of teachers and students. In the prior art, electronic display devices are also used, but viewing for a long time can easily cause visual fatigue and affect eyesight, and the use of electronic display devices usually requires a large amount of electric energy, which does not meet current social consumption concepts and health concepts. Contents of the invention [0003] The object of the present invention is to provide an optical energy writing device to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A light energy writing device, comprising a flexible substrate, a transpare...
