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 ...
