US 10,948,751 B2 · Anti-peep display device and anti-peep display method

Abstract

The present disclosure discloses an anti-peep display device and an anti-peep display device. The anti-peep display device includes a display layer and a liquid crystal grating layer; the liquid crystal grating layer is disposed at a surface of the display layer, and the liquid crystal grating layer includes two layers of glass substrate and a liquid crystal layer; these two layers of glass substrate are spaced apart and oppositely disposed; the liquid crystal layer is sandwiched between the two layers of the glass substrate; by adjusting the liquid crystal layer, a plurality of gratings of the liquid crystal grating layer are controlled to switch between black and white, thereby controlling the anti-peep display device to switch between an anti-peep display mode and a shared display mode.

An anti-peep display method for providing an anti-peep function to a display device, wherein the anti-peep display method comprises the following steps of:

providing a liquid crystal grating layer comprising two glass substrates spaced apart and disposed opposite to each other and a liquid crystal layer sandwiched between the two glass substrates;
arranging the liquid crystal grating layer at a surface of a display layer of the display device;
and
adjusting the liquid crystal layer to control a plurality of gratings of the liquid crystal grating layer to switch between black and white to adjustably form an anti-peep zone in a visible zone of the display device, so that the display device is controlled to switch between an anti-peep display mode and a shared display mode,
wherein the step of providing a liquid crystal grating layer further comprises:
designing an aperture ratio of the liquid crystal grating layer to be the same as an aperture ratio of the display layer.
