Abstract
The present invention provides a liquid crystal light valve pixel driver circuit comprising a pair of power electrodes, a pair of half-pixel electrodes, each half-pixel electrode being associated with a respective one of the power electrodes and a transistor switch for selectively conductively interconnecting the pair of half-pixel electrodes, the transistor switch being responsive to an applied data voltage potential. A strobe transistor and capacitor are further associated with the driver circuit to enable the demultiplexing of data from a data line and the transfer of a data representing voltage potential to the capacitor for application to the transistor switch.
