Beschreibung
Zusammenfassung:	The invention discloses a display device which comprises a display panel, a power supply integrated circuit, a comparison circuit and a selection circuit. The display panel is configured to receive a system voltage. The power supply integrated circuit is used for providing the system cross voltage to the display panel and comprises a current conversion circuit, and the current conversion circuit is used for converting a correction current output by the display panel when a correction picture is displayed into a detection voltage. The comparison circuit is used for comparing the detection voltage with a threshold value to generate a comparison result. The selection circuit is used for determining the magnitude of the system voltage according to the comparison result. Wherein the power supply integrated circuit is also used for correspondingly generating the system cross voltage according to the magnitude of the system cross voltage determined by the selection circuit so as to provide the system cross voltage d
