An ordinary display does not have characteristics to show all the specific information in a single screen. In order to solve the issues of insufficient screen space and also provide the realistic images, a novel 3D double-screen display is proposed to generate dual full-sized 3D images simultaneously. According to Snell’s Law, the proposed optical system for generating 3D and double-screen images is designed based on a single panel with only two additional components required: a planar mirror and a lenticular-lens based micro-optical structure. By modifying the lenticular-lens’ shape, size and position, the crosstalk issues were eliminated and the larger viewing angles were obtained. In addition, the micro-optical structure was fabricated by Excimer Laser Micromachining System without gray-scale mask. Based on its direct writing fabrication process, the shorter process time and the simpler steps are the advantages of producing huge amounts of precise functioning layers in economy and efficient. Moreover, the studies of implementing digital image processing and combining hardware components in the ordinary flat panel display provided viewers of two 3D images at top and bottom screens respectively and simultaneously. The low cost and simple converting technique of the proposed optical system for 3D double-screen displays, thus, promote the possibility of applications in display industry.
