3M has developed a 22-inch high-definition, multi-touch LCD based on its projected capacitive technology.

The M2256PW display is designed for professional applications that need up to 10-finger touch input or multi-user interactivity, with a touch response time less than 15ms for applications that are speed sensitive.

Introduced in June 2009 at SID Display Week as the 19-inch 3M Multi-touch Developer Kit, this technology offered software developers the first "full multi-touch" hardware platform.

Using this new technology, software developers can change the way users interact with all types of information and expand traditional touch interaction to include multiple users and increase collaboration.

The 3M Display M2256PW offers a high-definition 1680x1050 LCD screen, DVI and VGA video input, audio input, USB and RS232 (serial) dual-mode communication protocol and durable, anti-glare front surface.

Applications taking advantage of this high level of interactivity include computer aided design, digital signage, computer gaming, security monitoring systems, education and training and teleconferencing.

The M2256PW display is compatible with Windows 7, so no third-party touch drivers are required. For Linux and Windows XP/Vista/7 OS, 3M plans to offer a multi-touch driver and software utility, and will offer communication protocol documents for customers who wish to develop their own drivers.
