Abstract
Described herein are a display grating, a 3D display device, and a 3D display method, which can achieve free switching between a 2D display effect and a 3D display effect. The display grating comprises a grating substance. A first outer surface of the grating substance is provided with multiple reflective structures arranged in sequence; a first inner surface of the grating substance is provided with multiple scattering structures arranged in sequence; the scattering structures comprise multiple light-exiting points; and a first side surface of the grating substance is provided with multiple light sources arranged in sequence.

A display grating, comprising a grating substrate, wherein the grating substrate comprises:
- a first outer surface provided with a plurality of sequentially arranged reflective structures;
- a first inner surface provided with a plurality of sequentially arranged scattering structures with a plurality of light-exiting points;
- and
- a first side surface provided with a plurality of sequentially arranged light sources.
A 3D display device, comprising:
- a backlight panel;
- a liquid crystal display panel;
- a display grating located between the backlight panel and the liquid crystal display panels and comprising:
- a first outer surface provided with a plurality of sequentially arranged reflective structures;
- a first inner surface provided with a plurality of sequentially arranged scattering structures with a plurality of light-exiting point;
- and
- a first side surface provided with a plurality of sequentially arranged light sources;
- and
- a controller connected with the light sources through a control line, and configured to control the light sources to turn on through the control line when the display grating is in a 2D working state, and control the light sources to turn off through the control line when the display grating is in a 3D working state.
