| Abstract: | Based on the persistence of vision and high-speed light-emitting properties of LED, a volumetric three-dimensional (3D) display system of LED is designed. Firstly, the 3D datas are generated with MATLAB, and they are transported to the display driver circuit through the infrared module;Secondly, the LED array is rotated fast, and the value of rotational angle is got through Angle Encoder, then the corresponding two-dimensional cross-section graphs are calculated according to the value of the angle;Finally, the corresponding display can be achieved according to modulate the light-emitting and blanking of LED. The system is based on 24×16 two-dimensional LED array, and there are 69 120 individual pixels. The 3D display con be achieved wity φ94.4mm×66.8mm cylinder space. |
