Patent ID: 8334823

Claim:
A display device, comprising: a pixel array in which pixel circuits each having a light emitting element, a driving transistor for applying a current corresponding to a gate-to-source voltage to said light emitting element connected to a source side by applying a drive voltage across a drain and a source, a sampling transistor for inputting a signal line voltage to a gate of said driving transistor by being caused to conduct, and a sustaining capacitor connected between said gate and said source of said driving transistor for sustaining a video signal voltage inputted thereto are disposed in a matrix; a signal selector for supplying a reference voltage, an intermediate voltage, and a video signal voltage as the signal line voltage to each of signal lines disposed in said pixel array in columns in a time division manner; a drive control scanner for giving a power source pulse to each of power source control lines disposed on said pixel array in rows, and applying a drive voltage to said driving transistor of said pixel circuit; and a write scanner for giving a scanning pulse to each of write control lines disposed on said pixel array in rows to control said sampling transistor of said pixel circuit, thereby causing input of the signal line voltage to said pixel circuit to be carried out, wherein for control within one emission cycle of said pixel circuit based on the scanning pulse, said write scanner causes said sampling transistor to conduct while the signal line voltage is set as the reference voltage in order to cause correction of a threshold of said driving transistor to be carried out for a non-emission period of time within the one emission cycle, controls said sampling transistor while the signal line voltage is set as the intermediate voltage in order to cause input of the video signal voltage to said pixel circuit and correction of a mobility of said driving transistor to be carried out after the correction of the threshold, thereby boosting a gate voltage of said driving transistor from the reference voltage up to a level not reaching the intermediate voltage, keeps said sampling transistor in a non-conduction state for a given period of time, and causes said sampling transistor to conduct while the signal line voltage is set as the video signal voltage.
