System and method for a projected-capacitive touch screen with weight-based coordinate determination

摘要

A touch position on a capacitive touch-screen system is identified by receiving signals in response to a touch of electrical channels connected to one electrode or to a group of semi-contiguous electrodes present on a substrate. Adjacent ones of the electrodes have substantially triangular shapes alternating between a first and a second orientation to form a nested arrangement and the contact generates a signal cluster comprising the signals generated by a series of contiguous electronic channels. Weights having at least two different numerical values are applied to the signals from the series of contiguous electronic channels. The at least two different numerical values are based on levels of the signals. A position of the touch on the substrate is determined based on the weighted signals.
