Title (EN) DISPLAY PANEL AND OPERATING METHOD THEREOF, AND DISPLAY DEVICE

Abstract:
(EN) Provided are a display panel and operating method thereof, and a display device; said display panel comprises a first substrate (101) and second substrate (102), arranged opposite to each other; a liquid crystal layer (103) is arranged between the first substrate (101) and the second substrate (102); the first substrate (101) side facing the liquid crystal layer (103) is provided with an orthogonal polarizing layer (104), and the first substrate (101) side facing away from the liquid crystal layer (103) is provided with a first absorbing layer (105). When no electric field is loaded, the liquid crystal layer (103) transmits light in the first polarization direction, and the orthogonal polarizing layer (104) transmits light in the first polarization direction. When an electric field is loaded, the liquid crystal layer (103) converts the incident light in the first polarization direction to light emitted in a second polarization direction; the orthogonal polarizing layer (104) reflects light in the second polarization direction, and the first polarization direction and the second polarization direction are perpendicular to each other. The first absorbing layer (105) absorbs light incident to it. When the liquid crystal display device in a normally black mode is in a non-operating state, its display panel displays black, thereby increasing the contrast ratio of the display picture.
(FR) L'invention concerne un panneau d'affichage et son procédé d'exploitation, et un dispositif d'affichage ; ledit panneau d'affichage comprend un premier substrat (101) et un second substrat (102), agencés de manière opposée l'un à l'autre ; une couche de cristaux liquides (103) est agencée entre le premier substrat (101) et le second substrat (102) ; le côté du premier substrat (101) faisant face à la couche de cristaux liquides (103) comprend une couche de polarisation orthogonale (104), et le côté du premier substrat (101) opposé à la couche de cristaux liquides (103) comprend une première couche absorbante (105). Lorsque aucun champ électrique n'est chargé, la couche de cristaux liquides (103) transmet la lumière dans la première direction de polarisation, et la couche de polarisation orthogonale (104) transmet la lumière dans la première direction de polarisation. Lorsqu'un champ électrique est chargé, la couche de cristaux liquides (103) convertit la lumière incidente dans la première direction de polarisation en une lumière émise dans une seconde direction de polarisation ; la couche de polarisation orthogonale (104) réfléchit la lumière dans la seconde direction de polarisation, et la première direction de polarisation et la seconde direction de polarisation sont perpendiculaires l'une par rapport à l'autre. La première couche absorbante (105) absorbe la lumière incidente. Lorsque le dispositif d'affichage à cristaux liquides dans un mode normalement noir est dans un état de non-fonctionnement, son panneau d'affichage affiche du noir, ce qui augmente le rapport de contraste de l'image d'affichage.
(ZH) 一种显示面板及其工作方法、和一种显示装置,所述显示面板包括相对设置的第一基板(101)和第二基板(102),第一基板(101)与第二基板(102)之间设置有液晶层(103),第一基板(101)的面向液晶层(103)的一侧上设置有正交偏振层(104),第一基板(101)的背向液晶层(103)的一侧上设置有第一吸收层(105)。当不加载电场时,液晶层(103)透射第一偏振方向的光线,正交偏振层(104)透射第一偏振方向的光线。当加载电场时,液晶层(103)将入射的第一偏振方向的光线转换为出射的第二偏振方向的光线,正交偏振层(104)反射第二偏振方向的光线,第一偏振方向与第二偏振方向相互垂直。第一吸收层(105)吸收入射至其上的光线。该处于常黑模式的液晶显示装置在不工作状态时其显示面板呈现黑态,从而提高了显示画面的对比度。
