Art Lebedev will be pretty pissed today as a company called United Keys announced they've partnered with Foxconn to mass produce keyboards with OLED keys. The firm's first OLED keyboard will feature nine OLED keys and should be available in Summer 2008.
United Keys offers patented and patent-pending image-based interactive input technology, but with significant advantages in terms of usability and cost.
A fundamental difference between this approach vs. touch screen is that the tactile feedback associated with pressing a button is retained. This promotes familiarity. A second important advantage is the ease of modifying existing form factors, reducing time to market and component costs.
Unfortunately they didn't disclose the retail price yet.
