Abstract[English]
A reflective liquid crystal display, a cholesteric display, and a manufacturing method and driving method for a cholesteric display. The cholesteric display constructs a cholesteric microdroplet layer from broadband red, green and blue microdroplets, and is addressed by a TFT active matrix by means of vertical and in-plane switching. Cholesteric full-spectrum Bragg reflection ensures bright reflection and color reproduction. The cholesteric display not only provides video-speed dynamic pictures having infinite colors, but also provides excellent static images.[French]
L'invention concerne une unité d'affichage à cristaux liquides réfléchissante, une unité d'affichage cholestérique et un procédé de fabrication et un procédé de commande pour une unité d'affichage cholestérique. L'unité d'affichage cholestérique construit une couche de microgouttelettes cholestériques à partir de microgouttelettes rouges, vertes et bleues à large bande, et est adressée par une matrice active TFT au moyen d'une commutation verticale et dans le plan. La réflexion de Bragg cholestérique à spectre complet assure une réflexion lumineuse et une reproduction des couleurs. L'unité d'affichage cholestérique fournit non seulement des images dynamiques à vitesse vidéo ayant des couleurs infinies, mais fournit également d'excellentes images statiques.[Chinese]
一种反射式液晶显示器，一种胆甾显示器、胆甾显示器的制造方法以及驱动方法，其由宽带红色、绿色和蓝色微滴构造胆甾相微滴层，并且通过垂直平面切换TFT有源矩阵寻址。胆甾型全光谱布拉格反射确保了明亮的反射和色彩再现。不仅提供具有无限色彩的视频速度动态画面，而且还提供极好的静态图像。
