SED – The display technology of the future

The SED technology has appeared earlier here at NH and about two months ago we heard that Canon and Toshiba would start mass producing SED-based display panels in July 2007. SED is considered a very promising display panel technology that is suppose to bring together of the CRT technology, the contrast ratios and response time, and introduce them to the slim format of the Plasma and LCD technology. At Auphan Online they published an article about the SED technology where they dissect the technology and discuss the pros of the technology. By using the same basic principles of the CRT technology to generate light you get a display with true blackness and reponse time, contrary to LCD.

“The way SED TVs work is sort of like a combination of LCD screen with a CRT screen. The main display surface is basically the same as a CRT screen. It uses phosphors to generate light, but instead of a vaccum tube with an electron gun it uses layer of surface conduction electron emitters. Each set of emitters corresponds to one pixel. This allows for a slim design but still retains all the benefits of a CRT monitor minus all the negatives. There is no distortion near the edges of the screen like with CRTs and the display can be perfectly flat and uses less power than an LCD display.”

The first SED TVs are not expected until the end of 2006, but we will have to wait until the middle of next year for some consumer-related products. Alas, it will most likely take a while before the prices reaches decent levels, but it seems like a technology worth waiting for.
