Abstract
A detection device and method for touch panel are provided. The device includes a wiring module configured to ground lead of at least one of first touch electrodes; and a processing module configured to detect capacitance value of at least one of second touch electrodes one by one, and determine whether the second touch electrode is broken circuit according to the capacitance value of each of the second touch electrodes which is adjacent to at least one of the first touch electrodes. During detection, the at least one first touch electrode is grounded, and the second touch electrode and the first touch electrode with a lead grounded form a capacitor. If the second touch electrode is not broken circuit, the capacitance value detected is greater than the capacitance value when the first touch electrode is not grounded. It is beneficial for detecting accurately whether the touch electrode is broken circuit.
