Abstract
The application provides a touch apparatus, a drive circuit, a drive method and an electronic device. The drive method includes: in a pressure detection stage, providing a first pressure sensing signal to a part of detection electrode, and providing a second pressure sensing signal to the remaining detection electrodes. The first pressure sensing signal is not equal to the second pressure sensing signal. Through detecting a capacitance change between first pressure electrodes and second pressure electrodes, distance changes between a detection conductor and the first pressure electrodes and between the detection conductor and the second pressure electrodes are detected, to realize pressure sensing.
