Canon to Buy Toshiba's Stake in SED Inc.

Canon has just announced it will buy Toshiba's stake in the SED joint venture company to resolve the patent dispute with Nano-Proprietary Inc. that impeded Toshiba the access to an intellectual property in the area of surface electron conduction technology.

Because of this patent issue, Canon was not able to transfer a license to the joint venture company it formed with Toshiba.

To solve the problem, Canon has decided to buy the part of SEC Inc. owned by Toshiba, who has a 50 percent stake in the joint venture.

Canon also announced that it will review the plans SED Inc. had to build a $1.5 billion factory to mass produce the SED panels. Instead, Canon will manufacture the displays at its own plant for the launch of SED in Japan.

Surface-conduction Electron-emitter Display (SED) is a new type of 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. It’s like every pixel of a SED display is a miniature CRT, resulting in a discrete arrangement that will allow SED screens to behave like a digital display such as DLP.

As a result, SED has all the advantages of cathode ray tube (brightness and contrast levels, viewing angle) and none of the drawbacks of current flat panel display technologies.

The contrast ratio of SED is over 100,000 to 1, way better to those seen on LCD, and since the technology is self-luminous, the quality of the visuals does not depend on the viewing angle.

Since every pixel is like a miniature cathode ray tube, SED does not suffer from the high response times seen on LCD displays.

Slash readers are up on the SED debacle and offer more details of this tantalizing panel. Looks like a lot of the advancements have been held down by proprietary agreements as noted.
