A Comparison of the Temporal Characteristics of LCS, LCoS, Laser, and CRT Projectors

We have measured the temporal response of a commercial liquid crystal on silicon (LCoS) projector, and have compared it to that of commercial liquid crystal display (LCD) and cathode ray tube (CRT) projectors, as well as to a prototype laser projector. The faster temporal response of LCoS displays, as compared to more conventional LCDs, has not been considered a major factor in their commercial use, and so individual pixels are not turned on and off in these devices as quickly as the technology allows. Based on informal discussions with LCoS manufacturers and users, it appears that changes can be made in the LCoS display electronics to reduce pixel response times in order to sufficiently reduce smearing in moving simulator images.
