Abstract

A short circuit detection module for a touch panel includes first and second short circuit detection circuits. The first short circuit detection circuit is coupled to a first conductive line of the touch panel. The first short circuit detection circuit is configured to drive the first conductive line with a first signal having a first logic level. The second short circuit detection circuit is coupled to second, adjacent, conductive line of the touch panel. The second short circuit detection circuit is configured to drive the second conductive line with a second signal having a second logic level that is complementary to the first logic level.
