Abstract

The invention discloses a display panel with switchable wide and narrow viewing angles and a display device. The display panel with switchable wide and narrow viewing angles comprises a dimming box, and the dimming box comprises a first substrate, a second substrate opposite to the first substrate and a first liquid crystal layer arranged between the first substrate and the second substrate; the first liquid crystal layer comprises liquid crystal molecules and dye liquid crystal molecules which are mixed with each other, the light absorption capacity of the long axis of each dye liquid crystal molecule is larger than that of the short axis of each dye liquid crystal molecule, a first electrode strip is arranged on the first substrate, a second electrode strip is arranged on the second substrate, and projections of the first electrode strip and the second electrode strip in the direction parallel to the first substrate are mutually staggered. By driving the dye liquid crystal molecules to incline, the dye liquid crystal molecules absorb light in the direction of a large viewing angle, so that the dye liquid crystal molecules are darkened in the direction of the large viewing angle to achieve narrow viewing angle display, dazzling is avoided in the large viewing angle, a good narrow viewing angle effect is achieved, only the dye liquid crystal molecules need to be driven to deflect by a small angle, the driving voltage is low, and power consumption is saved.

Description

technical field [0001] The present invention relates to the technical field of display, and in particular, to a display panel and a display device capable of switching between wide and narrow viewing angles. Background technique [0002] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been widened from about 111° to more than 122°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect business secrets and personal privacy. Avoid business loss or embarrassment caused by the leakage of screen information. Therefore, in addition to the requirement of wide viewing angle, the display device is also required to have the function of switching between wide and narrow viewing angles in many occasions. [0003] At present, it is mainly adopted to attach a louver blocking film to the display screen to realize the switching between wide and narrow viewing angles. When p...
