With over 150 patents related to touch technologies, 3M Touch Systems expertise in this industry is extensive and ever increasing.
Dispersive Signal Technology is 3M's proprietary implementation of bending wave technology, which 3M has enhanced to optimize real-time touch response for large-screen public-access applications.
Dispersive Signal Technology's theory of operation is based on piezos, mounted in each corner of the glass sensors, collecting and converting the bending wave energy created by a touch into digital signals that are processed by proprietary algorithms residing in the touch controller.
The sophistication of any touch system is its electronics and 3M Touch Systems has been developing electronics solutions since the mid-1980’s.
Digital Signal Processing
Digital signal processing (DSP) algorithms are a core competency of 3M Touch Systems and 3M Dispersive Signal Technology (DST) uses these real-time DSP calculations to determine touch locations. The DST controller uses these advanced, proprietary algorithms to analyze the digital input provided by the piezo sensors.
