A driving circuit of an active matrix method in a display device is disclosed,
which can compensate luminance deviation of the display device according to threshold
voltage deviation of a driving unit. The driving circuit of the active matrix method
includes a switching unit switching a current applied from the driving unit to
the display device, and a deviation compensator detecting the current applied to
the display device by switching of a second switch, and controlling a control voltage,
thereby compensating luminance deviation of the display device according to threshold
voltage deviation of the driving unit.
