Title (EN) DISPLAY PANEL AND DISPLAY DEVICE
(FR) PANNEAU D'AFFICHAGE ET DISPOSITIF D'AFFICHAGE
(ZH) 显示面板及显示装置
Abstract:
(EN) Provided are a display panel and a display device. The display panel comprises multiple sub-pixels. Each sub-pixel comprises a display unit. The display unit comprises a first electrode (5), a second electrode (7), and a liquid crystal layer (6). A first black matrix pattern (1) is arranged at the first electrode (5) side. A second black matrix pattern (9) is arranged at the second electrode (7) side. The second black matrix pattern (9) has an opening (91). The first black matrix pattern (1) is arranged corresponding to the opening (91). If an electric field is generated between the first electrode (5) and the second electrode (7), the liquid crystal layer (6) between the first electrode (5) and the second electrode (7) can refract collimated light entering from the opening (91), such that at least a portion of the refracted light bypasses the first black matrix pattern (1) to exit the display panel. If no electric field is generated between the first electrode (5) and the second electrode (7), the first black matrix pattern (1) can completely block the collimated light entering from the opening (91). Grayscale display can be realized without a polarizer, thereby reducing costs of a display device, and reducing losses in optical efficiency.
(FR) La présente invention porte sur un panneau d'affichage et sur un dispositif d'affichage. Le panneau d'affichage comprend de multiples sous-pixels. Chaque sous-pixel comprend une unité d'affichage. L'unité d'affichage comprend une première électrode (5), une seconde électrode (7) et une couche de cristaux liquides (6). Un premier motif de matrice noire (1) est disposé au niveau du côté de la première électrode (5). Un second motif de matrice noire (9) est disposé au niveau du côté de la second électrode (7). Le second motif de matrice noire (9) comporte une ouverture (91). Le premier motif de matrice noire (1) est disposé par rapport à l'ouverture (91). Si un champ électrique est généré entre la première électrode (5) et la seconde électrode (7), la couche de cristaux liquides (6) entre la première électrode (5) et la seconde électrode (7) peut réfracter la lumière collimatée entrant à partir de l'ouverture (91), de sorte qu'au moins une partie de la lumière réfractée contourne le premier motif de matrice noire (1) afin de sortir du panneau d'affichage. Si aucun champ électrique n'est généré entre la première électrode (5) et la seconde électrode (7), le premier motif de matrice noire (1) peut complètement bloquer la lumière collimatée entrant à partir de l'ouverture (91). Un affichage en niveaux de gris peut être réalisé sans polariseur, ce qui permet de réduire les coûts d'un dispositif d'affichage et de réduire les pertes d'efficacité optique.
(ZH) 一种显示面板及显示装置,显示面板包括多个亚像素,每一亚像素包括显示单元,显示单元包括第一电极(5)、第二电极(7)以及液晶层(6),第一电极(5)侧设置有第一黑矩阵图形(1),第二电极(7)侧设置有第二黑矩阵图形(9),第二黑矩阵图形(9)具有一开口(91),第一黑矩阵图形(1)对应开口(91)设置;在第一电极(5)和第二电极(7)之间产生电场时,第一电极(5)和第二电极(7)之间的液晶层(6)能够对由开口(91)入射的准直光线进行折射,使得折射后的至少部分光线绕过第一黑矩阵图形(1)出射显示面板;在第一电极(5)和第二电极(7)之间未产生电场时,第一黑矩阵图形(1)能够完全遮挡由开口(91)入射的准直光线。从而无需偏振片即可完成灰阶显示,能够降低显示装置的成本,减少显示装置光效的损失。
