Naked eye 3D (three-dimensional) television wall

Abstract

The invention relates to a naked eye 3D (three-dimensional) television wall, comprising a full-color LED (light-emitting diode) array and a slit grating (or a lenticular grating), wherein the grating is arranged in front of an LED display array and parallel to an array plane; and the grating and the row direction of LEDs form an angle of inclination. When multi-view images are displayed on the LED array in a staggered mixing way, huge 3D images can be observed on the LED television wall without special glasses. In the traditional naked eye 3D television wall, an LED group containing three monochrouic LEDs is used as a basic display unit, which is similar to a red green blue sub-pixel structure on an LCD (liquid crystal display) panel. On the contrast, in the naked eye 3D television wall disclosed by the invention, the full-color LEDs are taken as the basic display units, so that the display resolution higher than that of the monochrouic LEDs is provided under the same LED arrangement density. The staggered mixing way of the multi-view images and the grating structure design which are required in the manufacturing of the full-color LED based naked eye 3D television wall are described in the specification of the invention.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a naked-eye 3D stereoscopic video wall realized by using a full-color light-emitting diode array. technical background [0002] In recent years, with the advancement of liquid crystal display technology, naked-eye 3D display technology, or autostereoscopic display technology, has made great progress. The principle of naked-eye 3D display technology is to send the images with subtle parallax on the display panel to the left and right eyes of the viewer through light occlusion or light refraction, etc., and fuse them in the brain to produce stereoscopic perception. At present, the main glasses-free 3D display technologies are mainly divided into two types: slit grating type and lenticular lens type. Since the grating is placed at an oblique angle to the column direction of the pixels, the loss of display resolution can be spread in both horizontal and vertical directions. For ...

Problems solved by technology

Similarly, when a basic display unit on the LED display array is a group of three single-color red, green and blue LEDs, the way of interlacing and mixing of multi-view images and the design of the grating structure are no different from those used for liquid crystal panels.
