A display device includes a display panel, a power integrated circuit, a comparison circuit and a selection circuit. The display panel is configured to receive a system cross voltage. The power integrated circuit is configured to provide the system cross voltage to the display panel and includes a current conversion circuit configured to convert a calibration current outputted by the display panel when displaying a calibration frame into a detection voltage. The comparison circuit is configured to compare the detection voltage with a threshold to generate a comparison result. The selection circuit is configured to determine a magnitude of the system cross voltage according to the comparison result. The power integrated circuit is configured to generate the system cross voltage according to the magnitude of the system cross voltage determined by the selection circuit to provide the system cross voltage to the display panel.
