摘要

Holographically formed polymer dispersed liquid crystal (HPDLC) materials meet the requirements for a video rate reflective display. In order to produce a saturated color from a Bragg reflector, the number of index changing layers becomes critical. The fabrication process affects the number of layers forming the reflector, and, as a result, the bandwidth and optical characteristics, including reflection intensity, direction, and spread, of the reflector. The cell thickness and the liquid crystal mixture affect the voltage at which the cell operates and the speed at which the liquid crystal material can switch from the reflective to non-reflective state. The cell designer is forced to work with all of these design parameters simultaneously. This research continues previous work evaluating reflective HPDLC display samples including a method to measure temporal response and refine color reflection characterization.
