Title: ANTI-PEEPING DISPLAY APPARATUS AND ANTI-PEEPING DISPLAY METHOD
Abstract:
An anti-peeping display apparatus and an anti-peeping display method. The anti-peeping display apparatus comprises a display layer (10) and a liquid crystal grating layer (20). The liquid crystal grating layer (20) is disposed at one side of the display layer (10). A resolution of the liquid crystal grating layer (20) is the same as that of the display layer (10). The liquid crystal grating layer (20) comprises two glass substrates, one above the other, and a liquid crystal layer. The two glass substrates are spaced apart from and opposite to each other. The liquid crystal layer is sandwiched between the two glass substrates. By adjusting the liquid crystal layer, multiple gratings of the liquid crystal grating layer (20) can be controlled to switch between black and white, such that the anti-peeping display apparatus is controlled to switch between an anti-peeping display mode and a display sharing mode. In the anti-peeping display apparatus of the invention, the liquid crystal grating layer (20) is disposed at one side of the display layer (10), that is, by adding only the liquid crystal grating layer (20) to an existing structure, a display apparatus is provided with an anti-peeping function, and is therefore enabled to switch between the anti-peeping display mode and the display sharing mode. In addition, the anti-peeping display apparatus of the invention has a simple structure and a small thickness, and causes only a small increase in cost.
