1. A multipoint mutual capacitance touch panel, comprising:
- a first layer of spatially separated drive lines formed in a first plane; and
a second layer of spatially separated sense lines formed in a second plane, the drive and sense lines crossing over each other to form a grid of mutual capacitance sensing nodes.

Abstract
A touch panel having a transparent capacitive sensing medium configured to detect multiple touches or near touches that occur at the same time and at distinct locations in the plane of the touch panel and to produce distinct signals representative of the location of the touches on the plane of the touch panel for each of the multiple touches is disclosed.
