ABSTRACT:
A smart pixel is comprised by a chiral smectic liquid crystal light modulator (45) (ferro-electric or electroclinic) disposed on a semiconductor substrate and having associated therewith electronic circuitry (41-44) formed in the semiconductor substrate in particular a single crystal silicon VLSI substrate, which circuitry is such as to provide localised intelligence (electrical signal processing and conditioning, pointwise operations, logic functions) at the modulator. The circuitry may comprise photodetector/threshold circuitry (FIG. 7) or digital-to-analogue conversion (FIGS. 3 or 4), for example.
