Abstract:
(EN) 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.
(FR) L'invention concerne un matériau spectroscopique contenant un mélange de cristaux liquides et un copolymère éthylène-acétate de vinyle. Le mélange de cristaux liquides contient des cristaux liquides nématiques négatifs, un additif chiral et un liquide ionique. Le rapport de masse du mélange de cristaux liquides et du copolymère éthylène-acétate de vinyle se situe sur la plage comprise entre 3/7 et 8/2. L'application continue d'un champ électrique sur un réseau n'est pas nécessaire pendant un affichage 2D et un affichage 3D, l'application d'un champ électrique étant nécessaire seulement lors d'une commutation entre un affichage 2D et un affichage 3. Ainsi, la consommation d'énergie d'un dispositif d'affichage à cristaux liquides 3D est réduite, les effets d'affichage sont accrus et la durée de veille est allongée. L'invention concerne également un procédé de préparation de ce matériau spectroscopique, un réseau, un procédé d'utilisation associé, ainsi qu'un dispositif d'affichage.
(ZH) 一种分光材料, 包括液晶混合物和乙烯-乙酸乙烯酯共聚物。液晶混合物包括负性向列相液晶、手性添加剂和离子液体,液晶混合物与乙烯-乙酸乙烯酯共聚物的质量比在3/7至8/2范围内。由于在2D显示和3D显示时不需要持续给光栅施加电场,只需要在2D显示和3D显示进行切换时施加电场,因此,可以降低3D液晶显示装置的功耗,提高显示效果,延长待机时间。还公开了一种分光材料的制备方法,光栅及其使用方法和显示装置。
