Abstract
The present disclosure relates to touch technology, and provides a touch detection method, a touch chip, and an electronic device. The touch detection method includes applying a driving signal to a driving channel of a touch screen, where the driving signal is encoded based on a preset encoding mode and includes a plurality of signal waveforms divided into waveforms in at least one correlated double sampling cycle. The same correlated double sampling cycle includes two sampling cycles and there is a phase difference of 180° between a waveform in one sampling cycle and that in the other sampling cycle. The touch detection method further includes receiving a sensing signal that corresponds to the driving signal and that is from a sensing channel of the touch screen; and determining a touch position information according to the sensing signal and according to an encoding information corresponding to the encoding mode.
