Patent ID: 7764248

Claim:
A display comprising: a pixel array configured to include pixel circuits that are arranged in rows and columns, each of the pixel circuits including an electro-optical element of which one end is connected to a first supply potential, a drive transistor that has a source connected to the other end of the electro-optical element and is formed of a thin film transistor, a sampling transistor that is connected between a data line and a gate of the drive transistor and captures an input signal dependent upon luminance information from the data line, a first switching transistor connected between a drain of the drive transistor and a second supply potential, a second switching transistor connected between the gate of the drive transistor and a third supply potential, a third switching transistor connected between the source of the drive transistor and a fourth supply potential, and a capacitor connected between the gate and the source of the drive transistor; and a driver configured to execute first mobility correction operation for correcting variation in a mobility of the drive transistor by writing an intermediate grayscale level to the gate of the drive transistor when the first switching transistor is in a conducting state, and execute after the first mobility correction operation, second mobility correction operation for correcting variation in the mobility of the drive transistor by writing the input signal to the gate of the drive transistor when the first switching transistor is in a conducting state.
