Abstract

A big-sized 2D-3D switching display device belongs to the field of optics and solves the problem of a glasses-free 3 D display field existing in a current LED large-screen. The display device comprises an LED screen, a glass substrate and a square light source box, wherein the glass substrate is arranged between the LED screen and the square light source box, which are parallel to each other; an optical thin-film is arranged on the surface of the side, facing the square light source box, of the glass substrate; the light source is arranged in the square light source box; a mask plate is arranged on the surface of a light-emitting side, facing the glass substrate, of the square light source box. The area of the LED screen is 10-20 square meters.

Description

technical field [0001] The invention relates to a large-size 2D-3D switching display device, which belongs to the field of optics. Background technique [0002] Restoring reality is the goal that people have been pursuing. Therefore, in recent years, stereoscopic display technology has become a major trend in the field of display. Through stereoscopic displays, you can also appreciate the realistic three-dimensional world, which can bring new visual and sensory experience to the audience. With the development and popularization of large-screen LEDs, the pixel pitch is getting smaller and smaller, and the price per square meter is getting lower and lower. Therefore, the demand for large-screen LEDs with stunning naked-eye 3D is increasing. [0003] The current 3D image display methods can be roughly divided into three categories, namely, glasses-type, head-mounted display-type, and naked-eye-type. Naked-eye 3D does not need to wear any auxiliary equipment and has become the ...
