NEC Display Solutions announced the enhancement of its LCD public displays product portfolio with 3M?s MicroTouch DST (dispersive signal technology) system as from today.

The touch screen technology, up to now only available with MULTEOS M40, M46 and NEC MultiSync LCD3215 models, has now also been made available for the NEC MultiSync LCD4020 and 4620. The enhancement of NEC?s touch solutions portfolio will be fully complete after a universal drivers update for all DST models in April 2009. This will make interactions with displayed objects much more versatile, with an expanded gesture recognition facility also enabling many more possibilities for user-display interactions.

The MicroTouch DST system for the NEC MultiSync LCD4020 and LCD4620 is based on a glass panel composed of a specially developed substrate material that has been equipped with sensor action to pick up the vibrations arising within the substrate arising from a finger or pen coming into contact with the glass. Thanks to the "dynamic touch" function, interactions can also be picked up even if larger objects have also been placed on the display?s surface.

MicroTouch DST technology comes as a fully-integrated solution and retains the elegant styling of NEC?s large format public displays. This is because additional bezels, which might otherwise impair the visual appearance of the display, are completely avoided.

An additional drivers update for the dispersive signal technology will become available in April 2009. This will allow NEC Display Solutions to satisfy the frequent desire for ever greater interaction flexibility. For example, objects displayed on the screen can now be changed and transformed in a considerably more versatile manner ? this includes grabbing, expanding, zooming or rotation of the display content. In addition, gestures such as scrolling are also recognised by the software
