Abstract

The embodiment of the invention provides a display device and a control method thereof. The display device includes a backlight structure layer and a display structure layer and further includes a light modulation layer. The light modulation layer comprises a first electrode layer, a second electrode layer and dielectric liquid arranged between the first electrode layer and the second electrode layer. The dielectric liquid is used for changing the wettability on the first electrode layer or the second electrode layer under action of the first electrode layer and the second electrode layer andcontrols the light out direction of the display structure layer. According to the embodiment, the light modulation layer is arranged between the backlight structure layer and the display structure layer, the light modulation layer is used for modulating the light emitted by the backlight structure layer and controlling the light out direction of the display structure layer, the directivity of display is achieved and the anti-peeping function is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a control method thereof. Background technique [0002] With the continuous development of display technology, liquid crystal display devices (Liquid Crystal Display, LCD) are widely used in various fields, bringing convenience to users in various aspects. At the same time, users are becoming more and more aware of personal privacy protection, and more and more scenarios require the display device to have an anti-peeping function. For example, in special places like hospitals, doctors often check the pathological information of patients through the display device, but they do not want the pathological information of these patients to be known by unrelated people. As another example, when a user performs an operation (such as inputting a password) on an automatic teller machine (ATM), the user does not want the content of the display device to be see...
