3M™ MicroTouch™ System DST2270DX
In most cheap large-format touch technologies "touch position" is calculated when
a finger interrupts an optical field, infrared light beams or acoustic waves on
or above the surface of the touch screen. Performance of such technologies are affected
by surface contaminants and environmental interference.
What's different about 3M DST is that it precisely calculates touch locations by
analyzing the bending waves within the glass substrate that are created by the user's
touch. Bending waves differ from surface waves in that they traverse through the
thickness of the panel rather than the surface of the material. This makes DST unaffected
by contaminants, scratches, or standing objects on the screen.
