1. A Surface-conduction Electron-emitter Display (SED) is a flat panel display technology that uses tiny electron emitters to energize colored phosphors and produce an image, similar to a matrix of small cathode ray tubes. 2. SEDs are being developed by companies like Canon and Toshiba as the next generation display, promising advantages over other technologies like higher contrast, faster response time, and lighter weight. 3. While SED appears close to commercialization, there are still challenges to overcome like potential screen burn-in and achieving large-scale mass production.
