Abstract
The present disclosure provides a voltage calibration circuit. The voltage calibration circuit includes a coupling voltage detection circuit and a common voltage circuit. The coupling voltage detection circuit is used for detecting a coupling voltage in an initial phase and generating a compensation voltage according to the coupling voltage. The common voltage circuit is used for adjusting a common voltage according to the compensation voltage and outputting the common voltage to a display module in a display phase.
