Title:
TOUCH-CONTROL DRIVING CIRCUIT, DRIVING CHIP AND TOUCH-CONTROL DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/183451
Kind Code:
A1
Abstract:
Provided in the present application are a touch-control driving circuit, a driving chip and a touch-control display apparatus. The touch-control driving circuit is used for outputting a driving signal to drive a driving electrode of a touch-control display apparatus. The touch-control driving circuit comprises a voltage generating circuit and a switching circuit, wherein the voltage generating circuit is electrically connected to the switching circuit. The voltage generating circuit comprises at least one energy storage capacitor, wherein the at least one energy storage capacitor is used for storing electric charges released by the driving electrode, and transferring the stored electric charges to the driving electrode. The switching circuit is used for controlling the voltage generating circuit to periodically output a power supply voltage, a first positive voltage, a second positive voltage, a third positive voltage and a zero voltage, wherein the first positive voltage, the second positive voltage and the third positive voltage are voltages provided by the at least one energy storage capacitor. The touch-control driving circuit has lower power consumption.
