ABSTRACT:
The present invention provides a display device comprising a display having an arrangement of a plurality of pixels, a drive IC for supplying to each pixel of the display data voltage or data current corresponding to a video signal fed from the outside, comparing/calculating unit for supplying the video signal to the drive IC, and a current monitor unit for measuring the total quantity of currents to have been passed through a plurality of pixels of the display. The comparing/calculating unit derives the sum of currents to be passed through each pixel of the display based on the values of the video signals for each pixel of the display, to correct the video signals for each pixel of the display based on the derived value and measurement value obtained by the current monitor unit.
