1. An active matrix electroluminescent display comprising:
- a circuit panel of pixels comprising an array of transistors and an array of pixel electrodes, each pixel electrode being electrically connected to at least one transistor, each transistor comprising source, drain and channel regions formed with a thin film of a single crystal silicon region;
an adhesive layer to bond the circuit panel with an underlying substrate;
an electroluminescent material positioned over each pixel such that an electric field or signal generated by a transistor within each pixel causes light emission by the material; and
a driver circuit electrically connected to the circuit panel for actuating the pixels.

Abstract
A display panel is formed using a single crystal thin-film material that may be 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.
