Title
(EN) DIMMING STRUCTURE, FABRICATION METHOD THEREFOR, AND DIMMING MODULE
(FR) STRUCTURE DE GRADATION, PROCÉDÉ DE FABRICATION ASSOCIÉ ET MODULE DE GRADATION
(ZH) 调光结构及其制作方法、调光模组
Abstract
(EN) A dimming structure, a fabrication method therefor, and a dimming module, which relate to the technical field of display. The dimming structure comprises: a first flexible substrate (31) and a second flexible substrate (32) arranged opposite to each other; a first transparent electrode (41) and a second transparent electrode (42) located between the first flexible substrate (31) and the second flexible substrate (32); a first alignment layer (51) located on the side of the first flexible substrate (31) facing the second flexible substrate (32); a second alignment layer (52) located on the side of the second flexible substrate (32) facing the first flexible substrate (31); and spacers (6) and a dye liquid crystal layer (7) located between the first alignment layer (51) and the second alignment layer (52). The dimming module may meet the dimming requirements of passenger car windows.
(FR) L’invention concerne une structure de gradation, un procédé de fabrication associé et un module de gradation qui se rapportent au domaine technique de l’affichage. La structure de gradation comprend : un premier substrat souple (31) et un second substrat souple (32) disposés à l'opposé l'un de l'autre ; une première électrode transparente (41) et une seconde électrode transparente (42) situées entre les premier et second substrats souples (31, 32) ; une première couche d'alignement (51) située sur le côté du premier substrat souple (31) faisant face au second (32) ; une seconde couche d'alignement (52) située sur le côté du second substrat souple (32) faisant face au premier (31) ; et des entretoises (6) et une couche de cristaux liquides de colorant (7) située entre la première et la seconde couche d'alignement (51, 52). Le module de gradation peut satisfaire aux exigences de gradation des fenêtres de voitures de tourisme.
(ZH) 一种调光结构及其制作方法、调光模组,属于显示技术领域。其中,调光结构,包括:相对设置的第一柔性基底(31)和第二柔性基底(32);位于第一柔性基底(31)和第二柔性基底(32)之间的第一透明电极(41)和第二透明电极(42);位于第一柔性基底(31)朝向第二柔性基底(32)一侧的第一取向层(51);位于第二柔性基底(32)朝向第一柔性基底(31)一侧的第二取向层(52);位于第一取向层(51)和第二取向层(52)之间的隔垫物(6)和染料液晶层(7)。调光模组能够满足乘用车车窗的调光要求。
