Patent ID: 8289245

Claim:
A display device comprising: a display unit having a plurality of pixels with each pixel having (i) a light emitting element and (ii) a pixel circuit; and a drive unit operable to drive the pixel circuits based on a video signal, wherein, each pixel circuit includes at least one transistor connected in series to the light emitting element, and the drive unit includes, (i) a first drive unit operable to supply a first voltage from a source or a drain of the transistor on the side opposite to the light emitting element, the first voltage being a voltage equal to or larger than a threshold voltage of the light emitting element, to the light emitting element, (ii) a second drive unit operable to supply three different kinds of voltages to a gate of the transistor including (a) a second voltage having a magnitude based on the video signal and (b) a third voltage having a predetermined magnitude from the gate of the transistor and (c) a fourth voltage having a magnitude less than the third voltage, and (iii) a control unit operable to (a) correct the potential difference between the gate and the source of the transistor to a threshold voltage of the transistor, (b) output a control signal a first time starting correction of mobility of the transistor while the second drive unit outputs the third voltage, and (c) output a control signal a second time starting writing of a voltage according to the second voltage to the gate of the transistor while the second drive unit outputs the second voltage.
