Display apparatus

A display apparatus comprising an image display unit having a plurality of arrayed pixel circuits, each of the pixel circuits having a current light emitting device and a driving transistor supplying current to the current light emitting device;

• and an image signal compensation circuit compensating an image signal and outputs the compensated signal to the image display unit;
• wherein each of the pixel circuits having a compensating capacitor which compensates a threshold voltage of a corresponding driving transistor;
• and
• the image signal compensation circuit having a compensation memory storing compensation data for compensating current dispersion between the driving transistors, a comparison circuit which compares the image signal with a threshold value of luminance, and an arithmetic circuit which outputs the compensated image signal being compensated based on the compensation data, and
• the image signal compensation circuit outputs the compensated image signal when the image signal has a luminance larger than the threshold value, and outputs the image signal when the image signal has a luminance smaller than the threshold value.
