Touch technology for large screen displays

Supplier News
article image Large LCD screens are becoming more and more popular.

3M Touch Systems has announced 30" and 40" touch screens integrated on liquid crystal displays (LCDs) enabling game maufacturers to design games for larger displays and for casino managers to implement touch for guest services applications.

The new screens incorporate 3M’s patented Dispersive Signal Technology that featured on 40" displays for the first time at the Global Gaming Exposition in Las Vegas.

Touch screen business manager Dan Savage said large LCD panels were becoming more and more popular as demand had steadily increased, and prices continued to come down.

“Casino managers can now utilise large panel displays by implementing touch applictions as casino directories or interactive advertising for events taking place throughout the casino.

"More creative, multi-player gaming applications are possible with large displays deployed as table games, bar top games, or even giant slot machines."

Dispersive Signal Technology offers a fundamentally different approach to touch. Unlike other solutions that recognise touch by the interruption of electrical fields, acoustic waves, or infra-red light, Dispersive Signal Technology recognises touch through vibrations made to the substrate.

By measuring specific vibrational energy, it eliminates issues with screen contaminants and surface scratches, while offering enhanced palm rejection - allowing accurate touch recognition when an object rests on the screen.

The MicroTouch DST substrate can be glass, tempered glass, glass integrated with 3M's Vikuiti films, or even acrylic - all of which offer excellent optical qualities.
