Toshiba showed a HD DVD player for cars at the Automotive Engineering Exposition 2007 in Japan.

Toshiba works with Alpine Electronics on the car HD DVD player to hit the market in 2008.

It is a natural development to bring HD into cars. Do we need it? Not necessarily today, considering most in-car movie systems have very small screens. Unless of course your car got pimped by MTV and sports now a 30 inch screen in the trunk.
At the same exhibition Toshiba showed a new touch panel that uses optical sensor along with a transistor formed on each pixel on the panel to detect fingers. The panel does not have any of the typical coatings that diminish the brightness of the screen. The new touch panel is developed by Toshiba Matsushita Display Technology Co., Ltd.
