Problems solved by technology

Obviously, if the three-dimensional grating is not configured, the pixel structure is unreasonable when used alone as a flat display screen. As a specially produced three-dimensional screen, it will inevitably increase the cost

Embodiment Construction

[0034] A three-in-one full-color LED display with a dot pitch of 2.5mm and a slit three-dimensional grating form a free three-dimensional display. 36*24 pieces of 16*16 dot matrix display modules constitute an LED display module. The size of the module is 144cm*96cm, with a total of 576*384 pixels. 3*3 display modules form an LED display with a size of 432cm*288cm and a display resolution of 1728*1152. The number of pixels of the stereoscopic image is 1728*1152, which is the same as the resolution of the display screen, and is synthesized by 6-viewpoint parallax images. The angle between the slit grating lines and the vertical direction is 26.565 degrees, the grating pitch is 6.657mm, and the slit width is 1.2mm. It is bonded with plexiglass and installed in parallel outside the LED display screen. The distance between the grating and the screen is 120mm. The slit grating can divide the stereoscopic image displayed on the display screen into multiple sequential parallax image...

Abstract

The invention discloses a high-definition LED autostereoscopic display screen which comprises a high-density LED three-in-one full-color display screen and stereoscopic gratings, wherein the stereoscopic gratings can adopt slit gratings or lenticular gratings, a stereoscopic composite image displayed on the display screen can be decomposed into multiple pieces of sequence parallax images which enter the left eye and the right eye of a viewer respectively, and accordingly, the autostereoscopic display is achieved. The high-definition LED autostereoscopic display screen has the outstanding advantages that compared with an LED screen comprising separated red green blue sub-pixels, three-time pixel density can be achieved, and the formed autostereoscopic display screen has high definition.

Description

Technical field: [0001] The invention relates to a large-scale autostereoscopic display screen, and more particularly, to a high-definition LED autostereoscopic display screen, which can be used for TV and advertisement playback. Background technique: [0002] The stereoscopic display has the characteristics of a large amount of information and can reproduce all the three-dimensional information of the actual scene, so that the viewer can directly see the distance and depth of each object in the image from the display screen, so the viewer can obtain a more comprehensive and intuitive view. information. The traditional stereoscopic display screen requires the viewer to wear auxiliary tools such as polarized glasses, complementary color glasses or active switching glasses. Although it has a good stereoscopic effect, it is not suitable for public places, especially the display of advertisements. [0003] In recent years, the naked-eye stereo technology without glasses has bee...
