Peep-proof display device and peep-proof display method

Abstract

The invention discloses a peep-proof display device which comprises a display layer and a liquid crystal grating layer, wherein the liquid crystal grating layer is arranged on one side of the display layer; the resolution of the liquid crystal grating layer is equal to that of the display layer; the liquid crystal grating layer comprises two layers of glass substrates and a liquid crystal layer; the two layers of glass substrates are oppositely arranged in a spacing manner; the liquid crystal layer is clamped between the two layers of glass substrates; by adjustment of the liquid crystal layer, multiple gratings of the liquid crystal grating layer can be controlled to be converted between black and white, so that the peep prevention function of the peep-proof display device can be controlled. According to the peep-proof display device provided by the invention, the liquid crystal grating layer is arranged on one side of the display layer, namely the peep prevention function of the display device can be realized by only additionally arranging the liquid crystal grating layer which is a device structure on the existing structure; furthermore, the device is simple in structure and thinner, and the cost increase is relatively low.

Description

technical field [0001] The present invention relates to the technical field of anti-peep display, in particular, to an anti-peep display device and an anti-peep display method. Background technique [0002] Liquid crystal display technology has become the mainstream display technology in the market. It has been able to meet people's needs in terms of pixel resolution, response time, screen size and other display technologies. However, in some special display environments, people need special display modes to To meet specific needs, for example, in an office environment or other private environments, people need the screen to be visible only to themselves and not to others. It is shared display mode. [0003] The existing anti-peeping display technology is mainly realized by adding special anti-peeping film materials, which can only realize the function of anti-peeping display but cannot realize the switching between anti-peeping display and shared display. In order to swit...

[0003] The existing anti-peeping display technology is mainly realized by adding special anti-peeping film materials, which can only realize the function of anti-peeping display but cannot realize the switching between anti-peeping display and shared display

In order to realize the switching between the peep-proof display and the shared display, the previous anti-peep display device added other structures on the basis of the above design to realize the switch between the peep-proof display and the shared display. However, the thickness of the device was too thick and the cost was too high.
