Abstract

A display device, a glasses-free three-dimensional display system and virtual reality (VR) glasses are disclosed. The display device includes a backlight; a polarizer disposed on a light-emitting side of the backlight and a plurality of liquid crystal displays (LCDs) stacked on a light-emitting side of the polarizer. Each LCD includes a plurality of light adjusting units; the light adjusting units of the plurality of LCDs are staggered from each other; and the light adjusting unit is configured to allow light emitted by the backlight to be refracted and emitted to a target position or be totally reflected.

Claims19

Dependent claims

A display device, comprising:

a backlight;
a polarizer disposed on a light-emitting side of the backlight;
and
a plurality of liquid crystal displays (LCDs) stacked on a light-emitting side of the polarizer, in which each LCD includes a plurality of light adjusting units;
projections of the light adjusting units of different LCDs of the plurality of LCDs on a substrate of one of the plurality of LCDs are not overlapped with each other;
and the light adjusting unit is configured to be switched between allowing light emitted by the backlight to be refracted and emitted to a target position and allowing light emitted from the backlight to be totally reflected in the light adjusting unit,
wherein each of the plurality of light adjusting units comprises a liquid crystal molecule layer.
