Title:
SENSOR CONTROLLER, ELECTRONIC APPARATUS, AND METHOD FOR CONTROLLING SENSOR CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2023/037690
Kind Code:
A1
Abstract:
The present invention relates to a sensor controller, an electronic apparatus equipped with the sensor controller, and a method for controlling the sensor controller. This sensor controller comprises: a plurality of transmission drivers; a plurality of output signal lines for outputting a transmission signal from the corresponding transmission driver to a corresponding detection electrode; and an intermediate potential supply unit having a potential generation unit that includes a voltage source or a capacitance element separately from the transmission drivers, the intermediate potential supply unit outputting a voltage from the potential generation unit synchronously with the initiation of transition of a signal waveform potential from a first potential to a second potential that is higher than the first potential or from the second potential to the first potential, thereby supplying an intermediate potential between the first and second potentials to the output signal line.
