Surface-conduction Electron-emitter Display (SED) panels could also become the next important technology in flat screens and dethrone DLP. It was created through the merging of Canon's proprietary electron-emission and micro-fabrication technologies with Toshiba's CRT technology and mass-production technologies for liquid crystal displays and semiconductors.
SED is a flat-panel display technology that utilizes the collision of electrons against a phosphor-coated screen to emit light, similar to a cathode ray tube but, instead of having one electron beam hitting the whole screen, each pixel has its own emitter since these are distributed in an amount equal to the number of pixels on the display. It’s like every pixel is a miniature CRT, forming a discrete arrangement that will allow SED screens to behave like a digital display such as DLP.
Since SEDs do not require electronic beam deflection, it is possible to build screens of more than 40 inches in size that are only a couple of inches thick.
All this results in a display technology that is as thin as an LCD display, but has none of its drawbacks because it has all the advantages of CRT, with the most important being its image quality-- superior to that found in all current flat display technologies.
