Abstract

The invention relates to an LED screen capable of achieving surface light emitting and a naked eye three-dimensional display device with the LED screen capable of achieving surface light emitting. The LED screen comprises LED pixel point arrays, black matrixes between LED pixel points, barrier frame arrays arranged above the black matrixes, and light evening plates arranged on the barrier frame arrays and used for diverging point light sources emitted by the LED pixel points into surface light sources. The LED pixel points correspond to barrier frames in a one to one mode to guarantee that crosstalk is not generated between adjacent LED pixel points. Reflecting film is arranged on the inner walls of the barrier frame arrays, and light irradiated to the inner walls of the barrier frames is easily transmitted. The LED screen and the naked eye three-dimensional display device have the advantages that adjacent light sources are separated through the barrier frame arrays, and the crosstalk is prevented; the point light sources emitted by the LED pixel points are diverged into the surface light sources through the light evening plates, the black matrixes in the LED screen are reduced or eliminated, light emitted by the pixel points is flexible, the moire fringe problem in a three-dimensional LED display system is solved, and the three-dimensional display performance is improved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to an LED screen capable of realizing surface light emission and a naked-eye three-dimensional display device thereof. Background technique [0002] Such as figure 1 An LED display screen structure packaged in the prior art mainly includes LED pixels (001) and a black matrix (002) between adjacent pixels. The black matrix in the LED display screen will make the aperture ratio of the display screen small, and the light-emitting surface is illuminated by a point light source, which will inevitably cause problems such as soft light emission and glaring display images. At the same time, when the LED display is applied to the naked-eye 3D-LED, the periodic arrangement between the existing black matrix and the grating array that generates the three-dimensional light splitting will cause Moiré fringes, which will affect the three-dimensional effect of the 3D display and cause the viewer...
