Abstract
Abstract A liquid crystal display includes: a) a sapphire substrate having a first crystal lattice structure; b) a single crystal silicon structure having a thickness no greater than about 100 nanometers affixed to the sapphire substrate to create a silicon-on-sapphire structure, and a second crystal lattice structure oriented by the first crystal lattice structure; c) an array of liquid crystal capacitors formed on the silicon-on-sapphire structure; and d) integrated circuitry formed from the silicon layer which is operably coupled to modulate the liquid crystal capacitors. The liquid crystals capacitors may include nematic or ferroelectric liquid crystal material.
