A design of nematic liquid crystal mode for the application of field-sequential-color microdisplay

摘要

Taking advantage of the transient effect of Optically-Compensated Bend(OCB) cells, we have optimized the parameters of bend cells to be used as a reflective microdisplay, especially for a single-imager Liquid Crystal on Silicon(LCoS). The optimized configuration features an on-off response time of less than 0.5 ms for a 2 micron cell driven by +-3.5 V, which is sufficiently compatible with existing electronics. Such a LCoS display is an outstanding candidate for the field-sequential-color projection application, which we're currently developing as a high-end target HD-TV with higher resolution of WUXGA(1,920x1,200) format.
