Privacy structure, display device and display method of display device

Abstract

The invention provides a privacy structure, a display device and a display method of the display device, and belongs to the technical field of display. The privacy structure comprises a first electrode, a second electrode and a plurality of transparent columnar cavities, wherein the first electrode is opposite to the second electrode, the transparent columnar cavities are between the first electrode and the second electrode, a plurality of opening areas are defined by the transparent columnar cavities which are filled with liquid and charged light-absorption particles in the liquid, and the longitudinal section of each transparent columnar cavity is trapezoidal. Under the action of the electric field between the first electrode and the second electrode, the privacy structure can be switched between a first state and a second state; in the first state, the charged light-absorption particles are uniformly dispersed in the transparent columnar cavities; in the second state, the charged light-absorption particles are concentrated at one ends of the transparent columnar cavities. By means of the privacy structure, it can be achieved that the display device is switched between a privacystate and a non-privacy state.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an anti-peeping structure, a display device and a display method thereof. Background technique [0002] With the development of display technology, display devices such as mobile phones and computers are more and more widely used. Generally, a display device has a relatively large viewing angle, and users at different viewing angles can obtain the displayed information. However, in some scenarios, users hope that the information displayed by the display device will not be known by other users around, that is, they want the display device to have an anti-peeping function. [0003] Existing anti-peeping display devices usually add an anti-peeping film outside the display screen to filter the light with a large viewing angle and only keep the light perpendicular to the display screen, so that users at positions with a large viewing angle cannot receive the pictures displayed on th...

Problems solved by technology

[0003] Existing anti-peeping display devices usually add an anti-peeping film outside the display screen to filter the light with a large viewing angle and only keep the light perpendicular to the display screen, so that users at positions with a large viewing angle cannot receive the pictures displayed on the display screen. The advantage of the anti-spy film is that it is separated from the display screen. The user can achieve the anti-peep effect by attaching the anti-spy film on the ordinary display screen, but the disadvantage is also obvious. The anti-spy film cannot actively realize the anti-peep state Toggle between peep states
