A naked-eye 3D holographic cylindrical display device based on the persistence of vision effect

Abstract

The invention provides a naked eye 3D holographic cylindrical surface display device based on a visual persistence effect. A principle that a point generates a line and a line generates a plane is utilized, colorful LED lamp beads namely packaged RGB LED lamp beads are integrally arranged in a line type, and lamp bars are formed. The display device comprises a rotation driving unit, a plurality of lamp arms, and connection arms connected with the rotation driving unit and the lamp arms in one-to-one correspondence. The connection arms are driven by the rotation driving unit to rotate around the rotation driving unit. The connection arm rotate synchronously with the connected lamp arms, and the rotating lamp arms form a 3D holographic cylindrical surface rotating around the rotation driving unit.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, and more specifically, to a naked-eye 3D holographic cylinder display device based on the persistence of vision effect. Background technique [0002] Compared with flat-panel LED display technology, three-dimensional (3D) stereoscopic image display has the characteristics of 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. , so viewers can get more comprehensive and intuitive information. In the past, people usually can realize the observation of three-dimensional information by means of 3D glasses. This method mainly uses the principle of parallax. When the viewer watches the picture, as long as two sets of images with slightly staggered shooting positions are provided for the left and right eyes to watch respe...

Problems solved by technology

[0005] However, the display devices manufactured by the above-mentioned naked-eye 3D display technology all have such disadvantages: since the display relies on panel-type display devices, as the display area expands, the number of display devices included in the display will gradually increase, and the cost will increase. It is getting higher and higher, which seriously restricts the current general expectation of viewing large-screen displays

In addition, with the increase of the area of ​​the display panel, its weight, the number of devices, etc. will bring inconveniences such as difficulty in installation and transportation, especially when it rotates, the rotation of the large-volume panel will easily make the inside of the panel along the The centrifugal effect in the radial direction of the rotation is significantly enhanced, which changes the internal stress of the display panel, which not only accelerates the aging of the panel, but also easily causes damage to the internal liquid crystal structure or circuit of the panel

In addition, when the panel rotates for too long, the wind resistance noise, wind force and heat generated by the panel will continue to spread out during the rotation process, affecting the viewing experience of the 3D display screen
