    摘要: 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.

    摘要: A display substrate, a display panel and a display device are provided. The display substrate includes a base, a first polarizer at one side of the base, and a light-splitting film between the first polarizer and the base. Multiple light-splitting structures are formed on a surface of the light-splitting film facing one side of the base, and the surface is divided into multiple light-splitting units, and the light-splitting structures in each light-splitting unit split light incident onto the light-splitting unit into multiple beams of light having different wavelengths and emergent directions. The display panel includes a first display substrate and a second display substrate arranged opposite to and forming a cell with the first display substrate, the first display substrate is the above display substrate. The display device includes the above display panel and a backlight source, a polarizer of the first display substrate faces the backlight source.
