Put simply, SED is the future of flat-panel displays. This technology “uses surface conduction electron emitters for every individual display pixel” to produce images with up to 100,000:1 contrast ratio. Videos after the jump.
The surface conduction electron emitter emits electrons that excite a phosphor 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 and Plasma displays with the high contrast ratios, refresh rates and overall better picture quality of CRTs. Canon also claims that SEDs consume less power than LCD displays
