A Surface-conduction Electron-emitter Display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction electron emitter emits electrons that excite a phosphorus coating on the display panel, the same basic concept found in traditional cathode ray tube (CRT) televisions. This means that SEDs can combine the slim form factor of LCDs with the high contrast ratios, refresh rates and overall better picture quality of CRTs. The surface conduction electron emitter apparatus consists of a thin slit across which electrons tunnel when excited by moderate voltages (tens of volts). When the electrons cross electric poles across the thin slit, some are scattered at the receiving pole and are accelerated toward the display surface by a large Voltage gradient (tens of kV) between the display panel and the surface conduction electron emitter apparatus. Toshiba and Canon Inc. have announced a joint development agreement originally targeting commercial production of an SED display by the end of 2005, but commercial products are now likely to first be available in 2006.
