(ZH) 一种显示装置及其显示方法
Abstract:
(EN) A display apparatus and a display method therefor. The display apparatus comprises: an optical device (15), a laser light source located at the light incident side of the optical device (15), a drive circuit connected to the optical device (15), and a holographic image data storage unit connected to the drive circuit. The optical device (15) comprises a plurality of mutually independent optical units; the optical units being able to refract the linearly polarized incident laser, the refractive indexes of the optical units being adjustable, the refractive index change of the adjacent optical units having a sine curve distribution. The drive circuit is configured to obtain, from the holographic image data storage unit image data of a hologram, image to be displayed, and adjust the refractive index of each of the optical units according to the image data, and the laser light source is configured to emit a laser beam corresponding to the holographic image to be displayed.
(FR) La présente invention concerne un appareil d'affichage et un procédé d'affichage correspondant. L'appareil d'affichage comprend : un dispositif optique (15), une source de lumière laser située sur le côté d'incidence de lumière du dispositif optique (15), un circuit d'attaque connecté au dispositif optique (15) et une unité de stockage de données d'image holographique connectée au circuit d'attaque. Le dispositif optique (15) comprend une pluralité d'unités optiques indépendantes les unes des autres ; les unités optiques peuvent réfracter le laser incident à polarisation linéaire, les indices de réfraction des unités optiques sont réglables, le changement d'indice de réfraction des unités optiques adjacentes présente une distribution de courbe sinusoïdale. Le circuit d'attaque est configuré afin d'obtenir, à partir des données d'image d'unité de stockage de données d'image holographique d'un hologramme, une image à afficher, et de régler l'indice de réfraction de chacune des unités optiques en fonction des données d'image, et la source de lumière laser est configurée afin d'émettre un faisceau laser correspondant à l'image holographique à afficher.
(ZH) 一种显示装置及其显示方法。显示装置包括:光学器件(15)、位于光学器件(15)的入光测的激光光源、与光学器件(15)连接的驱动电路、以及与驱动电路连接的全息图像数据存储单元。光学器件(15)包括多个相互独立的光学单元,光学单元能够对入射的线偏振的激光进行折射,光学单元的折射率可调,相邻的光学单元的折射率变化成正弦曲线分布。驱动电路用于从全息图像数据存储单元获取待显示的全息图像的图像数据,根据图像数据调整每一光学单元的折射率,激光光源用于发出与待显示的全息图像对应的激光光束。
