Dahan showcases 120-inch multitouch screen

Korean display maker Dahan today showcased one of the largest-ever screens to feature a multiple-input touchscreen. The DH1000W can range between 100 and 220 inches, and has been shown at 120 inches in size as proof that its rear-projection system works. As with the iPhone, the display accepts multiple touch and can use the feature both in custom-written software as well as resizing windows and navigating the interface in Windows 2000 or XP. Adding the technology doesn't significantly affect responsiveness, according to the company, with pixel lag holding to a 10ms average.

The cost of an individual unit is unavailable but will vary widely due to the available sizes. Dahan will begin delivering finished DH1000W models in October in its Korean home, but hasn't said if or when it will export the screen to the US market. [via AVING]
