Abstract:
A noise detection device includes a drive circuit, a sense circuit and a controller. The drive circuit drives a plurality of drive lines having a first polarity pattern and a second polarity pattern, wherein an operation of the first polarity pattern and the second polarity pattern substantially equals zero over a predetermined time period. The sense circuit senses a plurality of sense signals from at least one sense line during the predetermined time period. The controller derives a magnitude of a noise signal from the at least one sense line according to the sense signals.
