A stitchable naked-eye holographic display tool

Abstract

This application relates to the field of holographic display technology, and discloses a naked-eye holographic display tool that can be spliced, including at least two splicing units, and each splicing unit includes: a base; a transmission gear and a display screen installed on the base. The center line in the vertical direction coincides with the rotation axis of the transmission gear, and the transmission gear drives the display screen to rotate relative to the base; the data processing module; wherein, the transmission gears of every two adjacent splicing units mesh with each other and rotate at the same angular velocity; at least A part of the splicing unit is provided with a power device for driving the transmission gear to rotate; the width of each display screen is greater than the distance between the rotation axes of the two transmission gears and less than the distance between the rotation axes of the two transmission gears Twice as much, and satisfying that the two display screens do not interfere with each other when rotating. The splicable naked-eye holographic display tool disclosed in the present application uses gear transmission to realize the seamless splicing effect of the holographic display and saves costs.

Description

technical field [0001] The present application relates to the technical field of holographic display, and in particular, to a splicable naked-eye holographic display tool. Background technique [0002] The existing single-axis rotary holographic display technology realizes the holographic display effect by using the principle of visual persistence through high-speed rotation of the display screen and high-speed refresh. During imaging, the voxels move around the axis of rotation, and the voxels are sparse outside and dense inside, and large outside and small inside. Therefore, the size of the display is limited. In order to expand the display range, multiple holographic displays are generally arranged side by side. However, since the display area is a cylinder, there is a splicing blind area in the display area after splicing, and the ideal display effect cannot be achieved. SUMMARY OF THE INVENTION [0003] The present invention provides a splicable naked-eye holographic...
