Abstract:
A display device comprising:a display panel having a plurality of luminescent elements, luminance of which is determined according to a current density supplied thereto, the luminescent elements being grouped into a first luminescent section and a second luminescent section so that the luminescent elements having a luminescent area similar to a first size are grouped into the first luminescent section and the luminescent elements having a luminescent area similar to a second size are grouped into the second luminescent section; first current supply means for supplying current to each luminescent element in the first luminescent section; second current supply means for supplying current to each luminescent element in the second luminescent section; first current setter means, connected to the first current supply means, for setting a first amount of current to be supplied to each luminescent element in the first section; and second current setter means, connected to the second current supply means, for setting a second amount of current to be supplied to each luminescent element in the second section, wherein: the first and second amounts of current are set so that the current density supplied to each luminescent element in the first section and the current density supplied to each luminescent element in the second section become substantially equal.
