Abstract
(EN)
Disclosed are a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises: a plurality of red sub-pixels (1), green sub-pixels (2) and blue sub-pixels (3) that are arranged in sequence. The plurality of blue sub-pixels (3) are subjected to color offset improvement so as to present two different gamma curves during display, while the red sub-pixels (1) and the green sub-pixels (2) maintain the existing design, thereby improving the large view angle color offset, enhancing the penetration rate and optimizing the display effect of the liquid crystal display panel.
(FR)
L'invention concerne un panneau d'affichage à cristaux liquides et un dispositif d'affichage à cristaux liquides. Le panneau d'affichage à cristaux liquides comprend : une pluralité de sous-pixels rouges (1), de sous-pixels verts (2) et de sous-pixels bleus (3) qui sont agencés en séquence. La pluralité de sous-pixels bleus (3) sont soumis à une amélioration du décalage de couleur de façon à présenter deux courbes gamma différentes pendant l'affichage, tandis que les sous-pixels rouges (1) et les sous-pixels verts (2) conservent la conception existante, ce qui permet d'améliorer le décalage de couleur à grand angle de vue, d'améliorer le taux de pénétration et d'optimiser l'effet d'affichage du panneau d'affichage à cristaux liquides.
(ZH)
一种液晶显示面板及液晶显示装置。液晶显示面板包括:多个依次排列的红色子像素(1)、绿色子像素(2)及蓝色子像素(3);其中,多个蓝色子像素(3)在显示时能够呈现出两种不同的伽马曲线,通过对蓝色子像素(3)进行色偏改善处理使得蓝色子像素(3)在显示时能够呈现出两种不同的伽马曲线,而在红色子像素(1)及绿色子像素(2)则保持现有设计,能够改善液晶显示面板的大视角色偏问题,提升液晶显示面板的穿透率,优化液晶显示面板的显示效果。
