ABSTRACT:
A liquid-crystal-on-silicon device generates an image for projection onto a screen. The device includes a front plane, a back plane including a pixel driving circuit, and a wall that forms a chamber between the front and back planes for holding liquid crystal. Electrodes protrude into the chamber from the front plane, back plane, or both, in a predetermined pattern. The electrodes may be shaped as pillars and may serve as anodes or cathodes or both. When a voltage is applied to the electrodes, the liquid crystal assumes different polarization states at different pixel sites to form an image which may be projected onto a screen.
