Paper Abstract

In recent years, naked-eye 3D display technology that does not require glasses has attracted wide attention. Lenticular array display technology is one that has high luminance efficiency and is becoming the market trend. In this paper, we aim to design, fabricate and demonstrate full-resolution of autostereoscopic displays based on lenticular arrays on fullsize mobile displays. At present, our research has been carried out the optical design and simulation on a PMMA lenticular array. ZEMAX optical simulation software has been used to study the visual area analysis and imaging quality. The design of the PMMA lenticular lens array was completed, and the experimental framework of large-area up to 68x60 mm brass lenticular lens array mold was designed and completed. Ultra-precision machining of the brass mold has been carried out. Our team had also developed a specially constructed tool path generating software for ultra-precision diamond turning of lenticular lens surface onto flat or cylindrical roller surfaces. Tool path generation has been applied for machining the brass lenticular lens array mold. Because of its wide range of applications, the successful development of lenticular arrays will be of interest to the business community for 3D-enabled smartphones.
