Toshiba presented a brand new prototype 36 inch display at CES today. It’s based on a new technology developed by Canon and Toshiba called SED – Surface-conduction Electron-emitter.

Like a CRT, the SED shoots electrons at a phosphor-coated screen to emit light. But SED does it with electron emitters for each individual pixel in the display, not an electron gun shooting at the whole screen. Created through joint development work by Toshiba and Canon, the SED is the next-generation route to high definition images offering high brightness, contrast and color gradation levels, as well as fast video-response performance and low power consumption.
