Toshiba has shown off some auto-related products at the Automotive Engineering Expo 2007, including a mobile HD DVD player and a fresh take on touch panels. The high-definition in-dash player is under co-development with Alpine, and is planned for a 2008 release. The LCD is an improvement on traditional touchscreen technology, with no film coating -- which traditionally reduces contrast ratio and brightness -- to handle the user input, instead bundling optical sensors alongside each pixel. These sensors can then detect the shadow of a press during the day, and the reflection of the backlight at night. Toshiba also plans to upgrade that tech to use infrared instead of day/night sensors. Who cares if you can't see the difference between 1080 and 720 on a 7-inch screen, we just want our mobile touchscreen HD now!
