Autostereoscopic 3D display using directional subpixel rendering

Abstract

In this paper we present an autostereoscopic 3D display using a directional subpixel rendering algorithm in which clear left-right images are expressed in real time based on a viewer's 3D eye positions. In order to maintain the 3D image quality over a wide viewing range, we designed an optical layer that generates a uniformly distributed light field. The proposed 3D rendering method is simple, and each pixel processing can be performed independently in parallel computing environments. To prove the effectiveness of our display system, we implemented 31.5 '' 3D monitor and 10.1 '' 3D tablet prototypes in which the 3D rendering is processed in the GPU and FPGA board, respectively.
