Visual angle switching structure, display device and visual angle switching method of display device

Abstract

The invention provides a visual angle switching structure, a display device and a visual angle switching method of a display device. The visual angle switching structure comprises a plurality of visual angle switching units corresponding to all pixels on a display panel. Each of the visual angle switching units consists of a receiving chamber, a first solution layer, a second solution layer, and an electric field driving unit; the first solution layer and the second solution layer are arranged inside the receiving chamber and a liquid interface is formed between the first solution layer and the second solution layer; and the electric field driving unit is capable of generating a driving electric field applied to the receiving chamber. The first solution layer and the second solution layerhave different refractive indexes; the first solution layer is a transparent conducting solution; and the second solution layer is a transparent non-conducting solution. When the electric field generated by the electric field driving unit changes, the shape of the liquid interface between the first solution layer and the second solution layer changes. Therefore, the visual angle of the display device can be adjusted and thus effects of peeping prevention and the like are realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a viewing angle switching structure, a display device and a viewing angle switching method of the display device. Background technique [0002] With the development of communication technology, more and more users can realize functions such as entertainment, reading, and office work through mobile phones. Therefore, users can read files or view photos, videos, etc. on the mobile terminal anytime, anywhere and anywhere. However, in a busy mobile environment, such as subways, buses, and restaurants, it is inevitable that other people will be around the user, who may see the content displayed on the user's mobile phone, resulting in the leakage of the user's private information. [0003] In the prior art, display devices such as mobile phones cannot adjust the viewing angle through their own settings, and the viewing angle is usually controlled by sticking a film on the sc...

However, in a busy mobile environment, such as subways, buses, and restaurants, it is inevitable that other people will be around the user, who may see the content displayed on the user's mobile phone, resulting in the leakage of the user's private information

[0003] In the prior art, display devices such as mobile phones cannot adjust the viewing angle through their own settings. Usually, the viewing angle is controlled by pasting a film on the screen.

However, using a screen film to control the viewing angle requires maintenance of the protective film, and the viewing angle is fixed and cannot be restored
