摘要： A drive circuit including a drive transistor for feeding to a load a drive current corresponding to an input signal. The drive circuit has a correction circuit that supplies a correction signal corresponding to an impedance of the load to a gate of the drive transistor to correct the drive current to be fed to the load by the drive transistor, and in which the load is a light-emitting element. One terminal of the light-emitting element is connected to a gate of a transistor for correction, and when a predetermined potential Ps is set to a value calculated by deducting a threshold voltage Vth of the transistor for correction from a terminal potential Pi of the light-emitting element with respect to a drive current, the drive circuit sets a source potential of the transistor for correction to the predetermined potential Ps to thereby generate a voltage corresponding to an impedance of the light-emitting element as a source-to-drain current of the transistor for correction.

摘要： 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.
