A kind of led 3D display device

Abstract

An LED 3D display device includes: multiple groups of light emitting diodes, each group of light emitting diodes is provided with sub-pixels composed of four single primary color luminous bodies; multiple groups of prisms are symmetrically arranged on both sides of any sub-pixel; Each sub-pixel forms two groups of images through its adjacent prisms, which are respectively projected into the left and right eyes of the viewer. Multiple groups of prisms are symmetrically arranged on the left and right sides or the top and bottom sides of any sub-pixel, and the sub-pixels are distributed in strips or squares. The sub-pixels of different columns are arranged in a staggered manner, so that after different pixels pass through the prism, the color is more uniform and soft, and the light penetration effect is good, which solves the phenomenon of high contrast of each color and too deep local color. In addition, when the pixels are arranged in a square shape, the width of the prism increases. This arrangement reduces the display resolution, but the color is uniform. It is more suitable for the application of large-scale 3D display devices, and the manufacturing requirements are low. It is suitable for large-scale LEDs. TV Wall.

Description

technical field [0001] The present invention relates to a display device, in particular to an LED 3D display device. Background technique [0002] In recent years, display technology has developed rapidly. Compared with ordinary 2D screen display, 3D technology can make the screen three-dimensional and realistic. The image is no longer limited to the screen plane, as if it can go out of the screen, allowing the audience to experience Feel. Although there are many types of 3D display technologies, the basic principles are similar, which is to use the left and right sides of the human eye to receive different images, and then the brain superimposes the image information to form a display with front-back, up-down, left-right , far-near and other stereoscopic effects. [0003] Generally speaking, 3D stereoscopic displays are generally classified into naked-eye type, lenticular type, grating type and other types. Among them, the naked-eye 3D display needs to be within a specif...

Problems solved by technology

[0004] It is known that large-scale LED TV walls used outdoors can only present 2D display effects, but cannot display 3D stereoscopic images. In other words, it is still difficult to manufacture large-area LCD panels suitable for outdoor large-scale video walls, and the LCD panels that can be manufactured with current capabilities, if used on large-scale video walls, the manufacturing cost of video walls is often too high , unacceptable
