Description

[technical field] [0001] The invention relates to the field of electronic display, in particular to a 3D LED rotating display system. [Background technique] [0002] LED rotating display technology is a hot research field in recent years. It can fill voxels in real physical space to achieve natural three-dimensional display. The application prospect is broad. Based on this display technology, three-dimensional images with physical depth of field can be directly observed. It has many advantages such as panoramic view, multi-angle, multi-person simultaneous observation and real-time interaction. However, the resolution of the existing LED rotating display devices cannot reach high-definition display, and the frame rate cannot reach a high frame rate, the equipment is noisy, the outdoor daytime visibility is small, the battery power supply efficiency is low, and the battery life is poor, all of which limit the LED display. Wide application of rotating display technology. [0...
