Embodiment Construction

[0021] The first step is to divide the LED screen into several areas, and rearrange the pixel sets in some areas;

[0022] For example, if a screen with a resolution of 1920*1080 is divided into 24*24 areas, the resolution of each area is 80*45.

[0023] The specific area segmentation is shown in the following table. Use five characters to number the 24*24 areas. The first character is Z, which has no actual meaning. The second and third characters represent rows, the fourth and fifth characters represent columns, and Z0224 represents : line 02, column 24

Abstract

The invention discloses a moire-free naked-eye stereoscopic LED display screen with gratings installed vertically and an LED screen with rearranged regional pixels. On the basis of the existing LED screen and without changing the existing structure of each pixel unit, the LED screen with rearranged regional pixels is achieved through the following steps: step one, dividing the whole screen into a plurality of regions freely as long as the number of pixels contained in unit reason is larger or equal to 2; step two, selecting part of reasons divided in the step one; and step three, rearranging pixel arrays of the region selected in the step two. According to the moire-free naked-eye stereoscopic LED display screen with gratings installed vertically, the stereoscopic gratings including slit gratings and lenticular gratings are vertically installed on the LED screen, compared with the existing tilting installation, pixels of the LED screen are not cut, crosstalk is reduced, and the picture definition is improved. The vertical installation refers to that grating units are parallel to pixel arrays of the LED screen and the included angle is 0 degree; while the tilting installation refers to that an included angle is formed between grating units and pixel arrays of the LED screen and the included angle is larger than 0 degree.

Description

technical field [0001] The invention relates to a naked-eye three-dimensional display device using an LCD screen, an LED screen, a plasma screen and a three-dimensional grating (including a slit grating and a lenticular grating). In more detail, it involves using LCD screens, LED screens, and plasma screens as imaging units, slit gratings, and lenticular lens gratings as light-splitting elements, and the source obtained by fusing multi-viewpoint pictures and multi-viewpoint videos as the naked eye display content. Stereo imaging system. Background technique [0002] Naked-eye stereoscopic display means that you can enjoy videos and pictures with a sense of spatial depth without wearing glasses. [0003] There are many ways to realize naked-eye stereoscopic display, one of which is to use stereoscopic gratings (including slit gratings and lenticular lens gratings) with display screens (including LCD screens, LED screens, and plasma screens), and then match them with specific...
