Abstract
The invention discloses a curved liquid crystal display panel and a display device. The compensation mode of the lower compensation layer arranged between the lower polarizer and the array substrate and the upper compensation layer arranged between the upper polarizer and the opposite substrate is implemented. A change is made, the direction of the pretilt angle of the discotic liquid crystal molecules in the existing upper compensation layer is parallel to the direction of the light absorption axis of the upper polarizer to have a non-zero angle between them; similarly, the existing lower compensation The direction of the pretilt angle of the discotic liquid crystal molecules in the layer and the direction of the light absorption axis of the lower polarizer are parallel to each other so that there is a non-zero angle between them. The brightness of the sub-pixels in different regions of the curved liquid crystal display panel is adjusted to make the ratio of the light emitted by the sub-pixels in each region tend to be consistent, so that the final presented colors are consistent, so as to improve the problem of poor color shift in curved surface display.
Description
technical field [0001] The invention relates to the field of display technology, 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 human eyes and bring the best display picture and viewing experience to users, curved LCD TVs came into being. Curved LCD TV uses the elasticity of the liquid crystal display panel itself to realize curved display. However, the optical characteristics will change after the liquid crystal display panel is bent, resulting in different phase differences at different positions. [0003] In the TN mode liquid crystal display panel, in order to improve the viewing angle, a compensation layer is added between the polarizer and the liquid crystal display panel. The compensation layer adopts the principle of phase compensation for the viewing angle of the liquid crystal display panel to achieve wide viewing angle...
