Capacitive touch sensor architecture with unique sensor bar addressing |
摘要 |
A capacitive touch sensor with symmetrical electrical interconnections for use with a touch sensor of a device is disclosed. The touch sensor includes several sensor bars, with a unique pair of lead lines coupled to each sensor bar. No inter-connection is provided between individual sensor bars. The sensor bars may be substantially transparent, and may comprise indium tin oxide. The touch sensor may be disposed on a viewing screen or proximate thereto. Also disclosed is a system for providing a signal for use in determining a touch location. The touch sensor receives an electrical field, receives a touch, and provides a signal representative of the modulation of the electrical field caused by the touch, wherein the modulation is a function of the location of the touch and the signal is suitable for use by controller to determine the location of the touch.
