Title:
SPECTROSCOPIC MATERIAL, PREPARATION METHOD THEREFOR, GRATING, USE METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/152505
Kind Code:
A1
Abstract:
A spectroscopic material comprising a liquid crystal mixture and an ethylene-vinyl acetate copolymer. The liquid crystal mixture comprises negative nematic liquid crystals, a chiral additive, and an ionic liquid. The mass ratio of the liquid crystal mixture to the ethylene-vinyl acetate copolymer is in the range of 3/7 to 8/2. Continuous application of an electric field to a grating is not required during 2D display and 3D display, and the application of an electric field is required only when switching between 2D display and 3D display; therefore, the power consumption of a 3D liquid crystal display device is reduced, display effects are increased, and standby time is extended. Also disclosed are a preparation method for the spectroscopic material, a grating, a use method therefor, and a display device.
