基于OLED微显示器和变形目镜的全景显示技术

Panoramic imaging has been widely used in the applications of night driving, observation and surveillance in special vehicles etc. In this paper, a method of panoramic display based on OLED micro-display and anamorphic eyepiece is studied and proposed, and a set of panoramic display experiment system is designed. The image processing module is responsible for storing, buffering, pre-processing and transmitting the panoramic image data, and re-encoding the driving signal with the sub-pixels of the OLED micro-display as the display pixels. A horizontal 3× compression display of the panoramic gray image is realized in this paper. Finally, the compressed image displayed on the OLED micro-display is restored by anamorphic eyepiece for normal observation by human eyes. The experimental results show that the anamorphic eyepiece constructed by the existing system has not achieved the single-pixel resolution of the panoramic display, but the subpixel resolution of dual pixel target stripe has basically been achieved, and the feasibility of the panoramic display scheme proposed in this paper has been verified.
