Title (EN) REFLECTIVE LIQUID CRYSTAL DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE À CRISTAUX LIQUIDES RÉFLÉCHISSANT
(ZH) 反射式液晶显示面板
Abstract:
(EN) A reflective liquid crystal display panel. The reflective liquid crystal display panel is additionally provided with a white subpixel unit (34) in a pixel unit (30). Insofar as a pixel electrode (23) is provided below a color filter layer (24), the white subpixel unit (34) serves as a transparent film layer and a pixel electrode (23) serves as a reflective electrode, or the white subpixel unit (34) serves as a reflective film layer and the pixel electrode (23) serves as a transparent electrode or a nontransparent electrode; insofar as the pixel electrode (23) is provided above the color filter layer (24), the white subpixel unit (34) serves as a reflective film layer and the pixel electrode (23) serves as a transparent electrode. The reflective liquid crystal display panel utilizes the collaboration of the white subpixel unit (34) and the pixel electrode (23) to increase the utilization rate of ambient light so as to increase the brightness of the pixel unit (30), thus increasing the light emission brightness of the reflective liquid crystal display panel.
(FR) La présente invention concerne un panneau d'affichage à cristaux liquides réfléchissant. Le panneau d'affichage à cristaux liquides réfléchissant comprend notamment une unité de sous-pixel blanc (34) dans une unité de pixel (30). Dans la mesure où une électrode de pixel (23) se trouve en dessous d'une couche de filtre coloré (24), l'unité de sous-pixel blanc (34) sert de couche de film transparent et l'électrode de pixel (23) sert d'électrode réfléchissante, ou ladite unité de sous-pixel blanc (34) sert de couche de film réfléchissant et ladite électrode de pixel (23) sert d'électrode transparente ou d'électrode non transparente. Dans la mesure où cette électrode de pixel (23) se situe au-dessus de la couche de filtre coloré (24), l'unité de sous-pixel blanc (34) sert de couche de film réfléchissant et l'électrode de pixel (23) sert d'électrode transparente. Le panneau d'affichage à cristaux liquides réfléchissant utilise la collaboration de l'unité de sous-pixel blanc (34) et de l'électrode de pixel (23) pour augmenter le taux d'utilisation de la lumière ambiante de façon à accroître la luminosité de l'unité de pixel (30), augmentant ainsi la luminosité d'émission de lumière dudit panneau d'affichage à cristaux liquides réfléchissant.
(ZH) 一种反射式液晶显示面板。反射式液晶显示面板在像素单元(30)中增设了白色子像素单元(34),当像素电极(23)设于彩色滤光层(24)下方时,白色子像素单元(34)为透明膜层且像素电极(23)为反射电极,或者白色子像素单元(34)为反射膜层且像素电极(23)为透明电极或者非透明电极;当像素电极(23)设于彩色滤光层(24)上方时,白色子像素单元(34)为反射膜层且像素电极(23)为透明电极。反射式液晶显示面板利用白色子像素单元(34)与像素电极(23)的配合能够提高环境光的利用率,从而提升像素单元(30)的亮度,进而提升反射式液晶显示面板的出光亮度。
