High Accuracy Single Layer Touch Sensors Roll to Roll Processed on Plastic Substrates
Abstract:We present a metal mesh touch sensor fabricated by roll to roll printing on a thin flexible plastic substrate. High transparency and conductivity of the single layer device facilitate large sensor sizes and high accuracy. Due to mutual capacitance sensing the screen supports multi touch operation. Precision measurements performed on a xyz linear stage equipped with a metal test finger provide data for linearity and point accuracy of the touch sensor. The point accuracy is further analyzed statistically and shows a typical deviation of 0.46mm for a 3 inch x 2 inch one layer touchscreen.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
