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. However, the anti-peeping film has a shielding effect on the light of the vertical viewing angle, which reduces the display brightness of the vertical viewing angle
Some existing anti-peeping display devices add a backlight module between the anti-peeping film and the display screen. In the anti-peeping mode, the two backlight modules work simultaneously to solve the above-mentioned problem of display brightness. This method increases the brightness of the display device. power consumption

Abstract

The invention discloses a peep-proof display device. According to one embodiment of the invention, the device comprises a display screen; a diffusion film which is disposed at a display side of the display screen; and an adjustment apparatus which is used for enabling the diffusion film and / or display screen to move in a direction intersected with the plane of the display screen, so as to enable the relative distance between the diffusion film and the display screen to change. According to the embodiment of the invention, the device achieves a peep-proof function under the condition that the display brightness of a vertical view angle is not affected, and facilitates the reduction of the power consumption.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an anti-peeping device. Background technique [0002] With the development of display technology, electronic devices with display screens, such as mobile phones, computers, ATMs, etc., are more and more widely used. Generally, the display screen of an electronic 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 on the display screen cannot be known by other users around them, 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 ...
