Title
(EN) FRESNEL LIQUID CRYSTAL LENS AND DISPLAY DEVICE
(FR) LENTILLE DE FRESNEL À CRISTAUX LIQUIDES ET DISPOSITIF D'AFFICHAGE
(ZH) 菲涅尔液晶透镜和显示装置
Abstract
(EN)
A Fresnel liquid crystal lens and a display device. The Fresnel liquid crystal lens comprises an upper substrate (1) and a lower substrate (2) arranged opposite each other, and a liquid crystal layer (3) arranged between the upper substrate (1) and the lower substrate (2). A layer of a first electrode (4) is arranged on a surface opposite to the upper substrate (1) and two layers of second electrodes (5) are arranged on a surface opposite to the lower substrate (2). An electric field formed between the first electrode (4) and the second electrodes (5) enables the Fresnel liquid crystal lens to simulate the phase delay curve of an ideal Fresnel lens. The Fresnel liquid crystal lens enables liquid crystals to generate a vast phase change within an extremely small space, so that the Fresnel liquid crystal lens can simulate the phase delay curve of the ideal Fresnel lens more accurately and thus has better phase delay performance.

L'invention concerne une lentille de Fresnel à cristaux liquides et un dispositif d'affichage. La lentille de Fresnel à cristaux liquides comprend un substrat supérieur (1) et un substrat inférieur (2) agencés à l'opposé l'un de l'autre, et une couche de cristaux liquides (3) agencée entre le substrat supérieur (1) et le substrat inférieur (2). Une couche d'une première électrode (4) est agencée sur une surface opposée au substrat supérieur (1) et deux couches de secondes électrodes (5) sont agencées sur une surface opposée au substrat inférieur (2). Un champ électrique formé entre la première électrode (4) et les secondes électrodes (5) permet à la lentille de Fresnel à cristaux liquide de simuler la courbe de retard de phase d'une lentille de Fresnel idéale. La lentille de Fresnel à cristaux liquides permet à des cristaux liquides de générer un grand changement de phase à l'intérieur d'un espace extrêmement restreint, de telle sorte que la lentille de Fresnel à cristaux liquides peut simuler la courbe de retard de phase de la lentille de Fresnel idéale avec plus de précision et présente ainsi une meilleure efficacité de retard de phase.

一种菲涅尔液晶透镜和一种显示装置。该菲涅尔液晶透镜包括对盒设置的上基板(1)和下基板(2)以及设置在上基板(1)和下基板(2)之间的液晶层(3)。上基板(1)的对盒面上设置有一层的第一电极(4),下基板(2)的对盒面上设置有两层的第二电极(5)。第一电极(4)与第二电极(5)之间形成的电场能使菲涅尔液晶透镜仿真理想菲涅尔透镜的相位延迟曲线。该菲涅尔液晶透镜能使液晶在极小的空间内产生大幅度的相位变化,从而使菲涅尔液晶透镜能够更加精确地仿真理想菲涅尔透镜的相位延迟曲线,具有更好的相位延迟性能。
