Abstract

A voltage compensation method includes: within a touch time period, multiplexing common electrode blocks as touch electrodes, and scanning the common electrode blocks in at least one column sequentially to detect a capacitance of each scanned common electrode block; within a time period between detecting the capacitance of each scanned common electrode block and starting an Ndisplay time period after the touch time period, calculating power consumption for each scanned common electrode block in accordance with the capacitance thereof, acquiring a corresponding common electrode voltage compensation value based on the power consumption, and adding the common electrode voltage compensation value to a reference common electrode voltage to acquire a compensated common electrode voltage applied to each scanned common electrode block; and within the Ndisplay time period, adjusting a common electrode voltage applied to each scanned common electrode block into the compensated common electrode voltage.
