Abstract
A grey scale is generated by modulating light in response to an information signal using an electro-optical material. An analog sample is derived from the information signal, a drive signal is generated in response to the analog sample and the drive signal is applied to the electro-optical material. The drive signal has a sequence of a first temporal portion and a second temporal portion. The first temporal portion has a temporal duration that has a pre-determined relationship to the analog sample, and the second temporal portion is the temporal complement of the first temporal portion.
