Abstract

A touch panel includes a touch sensing circuit, an electrostatic discharge protection circuit and a processor. The touch sensing circuit is composed of a plurality of sensing pads for sensing a touch action of at least one touch object to output a sensing signal. The electrostatic discharge protection circuit is connected with the touch sensing circuit, surrounds the touch sensing circuit, and generates a circuit load. The processor is coupled with the touch sensing circuit and the electrostatic discharge protection circuit for receiving the sensing signal and the circuit load, performing a corresponding action according to the sensing signal and determining whether to generate an alarm signal according to the change of the circuit load.

Description

technical field [0001] The invention relates to a touch panel and a detection method of the touch panel, in particular to a touch panel and a detection method of the touch panel for judging the health status of the touch panel according to the load change of the electrostatic discharge protection circuit. Background technique [0002] In recent years, touch products have developed rapidly, and electronic devices with touch functions are widely used in daily life. However, although different inspection procedures have been arranged according to different assembly sequences in the manufacturing process of the touch panel, there may still be failures not detected due to some reasons, resulting in defective products entering the market. Therefore, how to determine whether the touch panel is abnormal after the touch panel leaves the factory is a problem to be solved at present. Contents of the invention [0003] To solve the above problems, an embodiment of the present inventi...
