Abstract
Embodiments improve projected-capacitive (PCAP) touchscreen performance for applications subject to water contamination. Embodiments include: increased separation between indium-tin-oxide (ITO)/silver connection of an electrode terminus and routing traces, and increased separation between electrostatic discharge (ESD) lines and sensor guard lines. Embodiments may include methods for rejecting false touches from self-capacitance readout mode measurements due to long water drops/rivulets on a touchscreen including peak ratios and locations of peaks on perimeter electrodes. Some embodiments include an optically clear adhesive layer between a first transparent substrate including a first ITO coating forming a first set of electrodes, and a second transparent substrate including a second ITO coating forming a second set of electrodes. The first transparent substrate may include non-solid trace shields that overlay on routing traces of the second transparent substrate; and the second transparent substrate may include non-solid trace shields that overlay on routing traces of the first transparent substrate.
