Display panel with switchable wide and narrow visual angles and display device

Abstract

The invention discloses a display panel with switchable wide and narrow viewing angles and a display device.The display panel can be switched between the wide viewing angle and the narrow viewing angle, the display panel is provided with a display area and a non-display area located on the peripheral edge of the display area, and the display area comprises a patterned diffusion area and a patterned non-diffusion area; the light scattering capability of the diffusion area is higher than that of the non-diffusion area. A patterned diffusion area and a patterned non-diffusion area are arranged on the display panel with switchable wide and narrow viewing angles, and the scattering capacity of the diffusion area to light is higher than that of the non-diffusion area to light, so that the viewing angle range of the diffusion area is different from that of the non-diffusion area when the display panel is at a narrow viewing angle; a user can see the light diffused in the diffusion area in the large-view-angle direction and can design the pattern of the diffusion area, so that the pattern corresponding to the diffusion area can be seen in the narrow-view-angle and large-view-angle direction, and the displayed picture can be seen in the anti-peep-angle range.

Description

technical field [0001] The present invention relates to the technical field of displays, 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 progress of liquid crystal display technology, the viewing angle of the display has been widened from about 112° to more than 160°. 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 privacy ...
