Title
(EN) SWITCHABLE GLASS AND PREPARATION METHOD THEREFOR
(FR) VERRE COMMUTABLE ET PROCÉDÉ DE PRÉPARATION ASSOCIÉ
(ZH) 调光玻璃及其制备方法
Abstract
(EN)
A switchable glass and a preparation method therefor, the switchable glass comprising: a first substrate (10) and second substrate (20) that are oppositely disposed, and a liquid crystal layer (30) and retaining walls (40) that are disposed between the first substrate (10) and the second substrate (20); liquid crystal molecules in the liquid crystal layer (30) are deflected under the action of an electrical field generated between the first substrate (10) and the second substrate (20) so as to control the light transmittance of the switchable glass; and the retaining walls (40) are grid-shaped, and are used to evenly disperse the liquid crystal molecules in the liquid crystal layer (30) in each grid of the retaining walls (40) and to maintain the box thickness between the first substrate (10) and the second substrate (20) when the switchable glass is bent.
(FR)
Verre commutable et son procédé de préparation, le verre commutable comprenant : un premier substrat (10) et un second substrat (20) qui sont disposés de façon opposée et une couche de cristaux liquides (30) et des parois de retenue (40) qui sont disposées entre le premier (10) et le second substrat (20). Des molécules de cristaux liquides dans la couche de cristaux liquides (30) sont déviées sous l'action d'un champ électrique généré entre les premier (10) et second substrats (20) de façon à commander la transmittance de lumière du verre commutable ; les parois de retenue (40) sont en forme de grille et sont utilisées pour disperser uniformément les molécules de cristaux liquides dans la couche de cristaux liquides (30) dans chaque grille des parois de retenue (40) et pour maintenir l'épaisseur de la boîte entre le premier substrat (10) et le second substrat (20) lorsque le verre commutable est courbé.
(ZH)
一种调光玻璃及其制备方法,调光玻璃包括:相对设置的第一基板(10)和第二基板(20)、以及设置在第一基板(10)和第二基板(20)之间的液晶层(30)和挡墙(40);其中,液晶层(30)中的液晶分子在第一基板(10)和第二基板(20)之间所产生的电场的作用下进行偏转,以控制调光玻璃的光线透过率;挡墙(40)呈网格状,用于将液晶层(30)中的液晶分子均匀分散在挡墙(40)的各个网格中,并在调光玻璃发生弯曲时,维持第一基板(10)和第二基板(20)之间的盒厚。
