A naked-eye 3D display device suitable for LED screens

Abstract

The invention provides a naked-eye 3D display device for an LED screen. The naked-eye 3D display device comprises a display device and a supporting device. The display device includes an ED display screen, a lenticular grating and a controller. The LED display screen and the controller are electrically. The supporting device includes a main body bracket and a device box; the device box having an Lshape is installed at the main body bracket; and a first displacement mechanism and a second displacement mechanism that are connected with the controller electrically are arranged in the device box.The LED display screen and the lenticular grating are fixedly installed in the device box; the lenticular grating is arranged right in front of the LED display screen; the LED display screen can moveback and forth or rotate horizontally in the device box by the first displacement mechanism; and the lenticular grating can move up and down in the device box by the second displacement mechanism. According to the invention, problems of single structure and poor functionality of the existing naked-eye 3D display device can be solved. Free switching between 3D displaying and 2D displaying is realized; and thus the user can watch a 3D picture or a 2D picture.

Description

technical field [0001] The invention relates to the field of naked-eye 3D technology, in particular to a naked-eye 3D display device suitable for LED screens. Background technique [0002] 3d is the abbreviation of three-dimensional, that is, three-dimensional graphics. Displaying 3D graphics in a computer means displaying three-dimensional graphics on a plane. Unlike in the real world, the real three-dimensional space has real distance space. The computer only looks a lot like the real world, so the 3D graphics displayed on the computer look real to people. One of the characteristics of the human eye is that it is larger when it is near and smaller than when it is far, so it will form a three-dimensional effect. Glasses-free 3D technology can be roughly divided into three types: light barrier type, lenticular lens type, and directional backlight 3D technology. Among them, the light barrier 3D display technology is to add a polarizing film and a polymer layer between the...
