Abstract
A display panel is formed using essentially single crystal thin-film material that is transferred to substrates for display fabrication. Pixel arrays form light valves or switches that can be fabricated with control electronics in the thin-film material prior to transfer. The resulting circuit panel is then incorporated into a display panel with a light emitting or liquid crystal material to provide the desired display.

An active matrix display comprising:
- an optically transmissive substrate;
- a silicon-on-insulator structure bonded to the optically transmissive substrate with an adhesive layer, the silicon-on-insulator structure having an array of transistor circuits formed therewith in a first plane to provide an active matrix array such that each transistor circuit is connected to a pixel electrode in an array of pixel electrodes;
- a counterelectrode panel extending in a second plane that is parallel to the first plane such that the insulator extends between the first plane with the array of transistors and the second plane;
- and
- a light transmitting material positioned over each pixel electrode such that actuation of a transistor circuit in the array alters an optical transmission property of the light transmitting material over the pixel electrode connected to the actuated transistor circuit.
