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.
Claims9
A liquid crystal light valve pixel driver circuit comprising:
- (a) a pair of power electrodes having a voltage potential applied thereinbetween;
- (b) a pair of half-pixel electrodes, each of said half-pixel electrodes being associated with a respective one of said power electrodes;
- and
- (c) a first transistor switch selectably conductively interconnecting said half-pixel electrodes, said first transistor switch being responsive to an applied voltage data potential.
A liquid crystal matrix display comprising:
- (a) a plurality of pairs of power electrodes;
- (b) a plurality of opposing pairs of half-pixel electrodes, each pair of half-pixel electrodes being associated with a given pair of said power electrodes such that each half-pixel electrode opposes a respective one of said power electrodes;
- and
- (c) a plurality of transistor switches, each said switch being operatively associated with a respective pair of said half-pixel electrodes so as to selectably conductively interconnect the half-pixel electrodes of said pair of half-pixel electrodes in response to a given data potential.
