DISPLAY DEVICE AND DRIVING CIRCUIT THEREOF

摘要

PURPOSE: A display device and a driving circuit thereof are provided to reduce the driving current of a display device by reducing power consumption of a source driving circuit and a common voltage driving circuit. CONSTITUTION: A source driving circuit(30) applies a source drive voltage to the source line of a display panel(100). A common voltage generation circuit(60) supplies first and second common voltages to a common electrode. A second common voltage is higher than the first common voltage. A control circuit(70) supplies a first external voltage to a source line and supplies a second external voltage to the common voltage.
