Abstract
The invention discloses a curved-surface liquid crystal display panel and a display device. The compensation mode that a lower compensation layer is arranged between a lower polarizer and an array substrate and an upper compensation layer is arranged between an upper polarizer and an opposite substrate is altered; the direction of the pre-tilt angle of disc-like liquid crystal molecules in the existing upper compensation layer and the direction of a light absorption shaft of the upper polarizer are parallel to each other, but in the curved-surface liquid crystal display panel and the display device, a non-zero included angle exists between the two directions; similarly, the direction of the pre-tilt angle of disc-like liquid crystal molecules in the existing lower compensation layer and the direction of a light absorption shaft of the lower polarizer are parallel to each other, but in the curved-surface liquid crystal display panel and the display device, a non-zero included angle exists between the two directions. The sub-pixel light-out brightness of different areas of the curved-surface liquid crystal display panel is adjusted, so that the light out ratio of each sub pixel in the areas tends to be consistent, finally the presented color is consistent, and the problem that the display color quality of a curved surface tends to be poor is improved.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a curved liquid crystal display panel and a display device. Background technique [0002] With the continuous development of LCD TVs, in order to adapt to the viewing effect of the human eye and bring the best display screen and viewing experience to users, curved LCD TVs came into being. Curved LCD TVs use the elasticity of the LCD panel itself to achieve curved display. However, the optical properties change after the LCD panel is bent, resulting in different phase differences at different positions. [0003] In the TN mode liquid crystal display panel, a compensation layer is added between the polarizer and the liquid crystal display panel in order to improve the viewing angle. The compensation layer adopts the principle of phase compensation for the viewing angle of the liquid crystal display panel to realize wide viewing angle display. Specifically, as Figur...
