Nakedness-eye holographic display device based on persistence-of-vision effect and method for nakedness-eye holographic display device

Abstract

The invention discloses a nakedness-eye holographic display device based on a persistence-of-vision effect. The nakedness-eye holographic display device comprises a plurality of LED (Light Emitting Diode) lamp strips and a rotating disk, wherein the inner ends of the LED lamp strips are fixedly connected with the rotating disk; the LED lamp strips are uniformly distributed along a rotating center of the rotating disk and comprise lamp poles and RGB (Red, Green and Blue) lamp beads; the RGB lamp beads are linearly fixed on the lamp poles. A display method of the nakedness-eye holographic display device comprises the following steps in sequence: determining a display area and resolution; calculating a rotation period; calculating refresh time; displaying picture data processing. According to the nakedness-eye holographic display device disclosed by the invention, by using the principle of point-into-line and line-into-plane, the RGB lamp beads are arranged in a line form and move according to certain trajectory to form a trajectory plane; the picture can be displayed according to pixel points (the RGB lamp beads) corresponding to a lightening trajectory plane required by the picture; due to the motion of the lamp strips, a realistic background can be transmitted through the trajectory plane of lamp strip motion, and a display picture theme is displayed in the realistic environment in a floating way.

Description

technical field [0001] The invention relates to the field of LED display, in particular to a naked-eye holographic display device and method based on the persistence of vision effect. Background technique [0002] Due to the development of LED technology and its unique advantages, such as low cost, long life and high height, LED is widely used in lighting, display and so on. [0003] In terms of LED displays, the existing LED displays in China are based on planes, and the multi-colored lamp beads, that is, RGB three LEDs are concentrated in one closed, arranged in a matrix form, and the screen is displayed in the form of progressive or interlaced scanning. Mainly used in large displays, outdoor advertising, etc. [0004] With the development of 3D technology, the principle of parallax is mainly used. When the viewer watches the picture, as long as two sets of pictures with slightly staggered shooting positions are provided for the left and right eyes to watch respectively, ...

AI Technical Summary

Problems solved by technology

[0005] Because the existing 3D display technology is based on the plane, the lamp beads are arranged in a matrix on the plane, and the displayed theme and the background are placed on the same plane, but it is impossible to completely place the displayed theme on the realistic background, that is to say, the original 3D display technology always has a display background, which is the background of the original video screen, not a realistic background where the display is located
