  • Publication number: 20050179626
    Abstract: In a pixel circuit that accumulates a display signal Vsig in a capacitor and supplies a display current to a light-emitting element using a TFT serving as a drive transistor in order to correct fall of a luminance due to aged deterioration of the light-emitting element, the pixel circuit supplies the display current to a gate of a TFT and sets a source of the TFT to a value obtained by deducting a threshold value of the TFT from an anode potential of the light-emitting element with respect to the display current using a variable bias voltage to thereby extract an amount of an increase of a voltage due to the aged deterioration of the light-emitting element as a source-to-drain current of the TFT. The pixel circuit feeds the source-to-drain current from the capacitor as a correction signal and adjusts a gate potential of the TFT serving as the drive transistor to thereby correct the display current and correct a luminance of the light-emitting element.
