Abstract
A drive circuit, a touch drive apparatus, and an electronic device are provided. The circuit comprises a first node, a second node, a ground node, a switch circuit, and an energy storage capacitor. The first node is configured to provide a first positive voltage. The second node is configured to provide a first negative voltage. The switch circuit is configured to control a first terminal of the energy storage capacitor to be selectively connected to the ground node or the drive electrode, and control a second terminal of the energy storage capacitor to be selectively connected to the ground node or the drive electrode. In one phase, the first terminal of the energy storage capacitor receives charges released from the drive electrode. In another phase, the second terminal of the energy storage capacitor charges the drive electrode using stored charges.
