Title:[Invited] Design of Three-Dimensional Displays with Digital Micromirror Device
Joonku?Hahn (Kyungpook Nat'l Univ., Korea)
Abstract: Three-dimensional(3D) displays require quite large amount of information for providing multiple views to observers. So, digital micromirror devices(DMDs) have received lots of interest for constructing 3D displays since they have outstanding properties in the bandwidth. However, low color depth could be critical and the increase of the time for gray-level PWM brings the decrease of the refresh rate of the DMD. 3D displays with the DMD have another advantage in color consistency since the DMD is a device to reflect the incident light and it must have a strong point for multiplexing. In many cases, mechanical scanners are applied for increasing the range of the scanning angle, but there are alternative ways that the light source array can be useful if the only small deviation of the incident angle is necessary. The information of the light field can be divided into several pieces for multiplexing. For space-multiplexing, the light field is usually divided at the image plane and for time-multiplexing, it is divided at the Fourier plane to provide different views according to the direction. But in some cases such as holographic display, the division at the image plane may be better for the quality of the reconstruction image.
