Touch detection chip, touch display apparatus, method of touch detection, and storage medium

Abstract

The present application provides a touch detection chip with a driving circuit. The driving circuit outputs a plurality of excitation signals in different frequencies and phases to driving paths. The excitation signals include chip waveforms and corresponding controlling signals. The controlling signals include a plurality of static controlling signals transmitted in a parallel manner and a plurality of dynamic controlling signals. The driving circuit includes a conversion module and a signal processing module. The conversion module converts the static controlling signals in a same driving period into a serial controlling signal. The driving period includes a signal transmission period and a pre-processing period. The signal processing module provides the serial controlling signal to the driving paths in the signals transmission period, and obtains configuration signals corresponding to a next chip waveform. A touch display apparatus, a touch detection method, and a storage medium are also provided.
