Abstract
A display panel includes a display module including a plurality of pixels connected to gate lines and source lines and a driver module configured to apply driving voltages to the gate lines and the source lines. The driver module includes a driving voltage generator configured to generate the driving voltages and a calibration circuit configured to compare each of the driving voltages with a reference voltage and to output a calibration parameter according to a comparison result. The driving voltage generator calibrates each of the driving voltages using the calibration parameter.
