Abstract:
(EN) An optical device, a display apparatus and a method for driving same. The optical device comprises two substrates (100, 200) arranged opposite to each other; the two substrates (100, 200) are respectively provided with electrodes (1, 2), and a voltage is applied to the electrodes (1, 2) to form a transverse electric field to drive liquid crystal molecules close to the substrates (100, 200) to deflect, so that liquid crystals close to the two substrates (100, 200) can all form liquid crystal lenses (11, 12), thereby forming a double-layer liquid crystal lens structure. Due to the relatively high alignment precision between the two substrates (100, 200) of a liquid crystal cell, it can be ensured that the electrodes (1, 2) on the two substrates (100, 200) are consistent in spatial frequency, and the problem of moire can be resolved.
(FR) L'invention concerne également un dispositif optique, un appareil d'affichage et un procédé de commande de celui-ci. Le dispositif optique comprend deux substrats (100, 200) disposés à l'opposé l'un de l'autre; les deux substrats (100, 200) sont respectivement pourvus d'électrodes (1, 2), et une tension est appliquée aux électrodes (1, 2) pour former un champ électrique transversal pour entraîner des molécules de cristaux liquides proches des substrats (100, 200) pour dévier, de telle sorte que des cristaux liquides proches des deux substrats (100, 200) peuvent tous former des lentilles à cristaux liquides (11, 12), formant ainsi une structure de lentille à cristaux liquides à double couche. En raison de la précision d'alignement relativement élevée entre les deux substrats (100, 200) d'une cellule à cristaux liquides, il est possible de garantir que les électrodes (1, 2) sur les deux substrats (100, 200) sont cohérentes en fréquence spatiale, et le problème de moiré peut être résolu.
(ZH) 一种光学器件、显示装置及其驱动方法。该光学器件包括相对设置的两个基板(100、200),在两个基板(100、200)上分别设置有电极(1、2),并向该电极(1、2)施加电压,形成横向电场,来驱动靠近基板(100、200)的液晶分子偏转,以使靠近两个基板(100、200)的液晶均能够形成液晶透镜(11、12),从而形成双层液晶透镜结构。由于液晶盒的两个基板(100、200)的对位精度较高,能够保证两个基板(100、200)上的电极(1、2)在空间频率上一致,克服摩尔纹问题。
