Abstract

The invention discloses a display panel, a display device and a view angle control method of the display panel. The display panel comprises an array substrate, a color film substrate and a liquid crystal layer, wherein the array substrate and the color film substrate are arranged oppositely, and the liquid crystal layer is located between the array substrate and the color film substrate. A plurality of strip-shaped control electrodes are arranged at one side, adjacent to the liquid crystal layer, of the color film substrate. A common electrode and a pixel electrode are arranged on the array substrate. Orthographic projections, on the array substrate, of the strip-shaped control electrodes are located in an orthographic projection, on the array substrate, of the common electrode or the pixel electrode. The strip-shaped control electrodes are used for exerting bias voltage to adjust the view angle of the display panel. The display device comprises a drive chip and the display panel. The drive chip is used for displaying drive. The controllable adjustment of the view angle of the display panel can be achieved by means of the display panel and the display device.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a display panel, a display device, and a viewing angle control method of the display panel. Background technique

[0002] Due to the advantages of thinness, energy saving, and low power consumption, liquid crystal display devices have been widely used in electronic equipment such as televisions, computers, mobile phones, and digital cameras. Currently, wide viewing angles are the mainstream development direction of liquid crystal display devices, and liquid crystal display devices in wide viewing angle mode can enable people to see complete and undistorted images from different directions. However, when personal privacy and important information are involved, the user does not want people around to observe the displayed picture, so in this case, the display device with a wide viewing angle will cause inconvenience to the user.

[0003] In the prior art, in order to real...
