摘要
基于人眼视觉暂留特性及LED的高速发光特性,设计了一套LED体三维显示系统。首先利用Matlab生成三维数据,通过红外模块传输到显示驱动电路;其次快速旋转LED阵列,由角度编码器获取旋转角度值,并根据角度值计算对应的二维截面图形;最后通过调制LED的发光与消隐实现相应的显示。该系统基于24×16二维LED阵列,具有69 120个体像素,实现了空间尺寸为φ94.4 mm×66.8 mm的稳定柱体内三维显示。
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 can be achieved with φ94.4 mm×66.8 mm cylinder space.
