Abstract

The invention provides an electronic device. The electronic device comprises a writable display device, and the writable display device comprises a first substrate, a second substrate, and a liquid crystal layer formed between the first substrate and the second substrate, and the liquid crystal layer is cholesteric liquid crystal; and the screw pitch of the cholesteric liquid crystal is changed along with the change of temperature, and the wavelength of reflected light is changed along with the change of temperature. According to the electronic device provided by the invention, writing traces with different colors can be displayed on the writable display device, so that the writing experience is further enriched.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a writable display device, a writing device and an electronic device. Background technique [0002] The unique helical structure of cholesteric liquid crystal material endows it with special optical properties, and its different texture morphologies correspond to different optical properties. The cholesteric system in the planar texture state has selective reflection characteristics, and the pyramidal texture of the cholesteric system has an unstable orientation corresponding to the handed and helical axes in the liquid crystal system, and its chaotic arrangement makes the liquid crystal system exhibit strong light scattering. state. The transition of these two states can be controlled by external pressure, electric field and magnetic field, etc., so as to realize the display function. The display device designed using this characteristic of the cholesteric liqu...
