Abstract

The invention discloses a 3D display device and a method. The device comprises an LED (light emitting diode) display used for displaying an image; a light path control structure of a multi-layer pinhole structure and used for controlling the light path emergent direction of the image so as to form the three-dimensional light field information; and a holographic function screen used for carrying out diffusion imaging on the three-dimensional light field information to form a 3D image. The LED display, the light path control structure and the holographic function screen are arranged in sequence. Each layer of the pinhole structure is provided with a plurality of groups of pinhole arrays. According to the invention, the technical problem of poor 3D effect in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of 3D display, in particular to a 3D display device and method. Background technique [0002] The 3D light field display technology is considered to be one of the most promising technologies in the field of 3D display because it can realize a real and remarkable naked-eye 3D display effect and can process imaging in real time. [0003] At present, the structure of the display device based on the light field display technology of the common display is as follows: figure 1 shown. The basic principle is based on a shading plate with a small hole and an ordinary display. The image displayed in the display can be encoded by a computer to obtain a light field display unit with m×n resolution, and then the light field display unit can be controlled by using the opening of the shading plate. The direction and intensity of each light emitted by the unit, that is, an array of light field display units modulated by enc...
