Display device and driving method of the same |
摘要 |
The present invention provides a circuit configuration for applying a reverse voltage (or a reverse bias) for enhancing the reliability by controlling the degradation of the light emitting element in a display device having a pixel circuit, and a method thereof. A reverse voltage is applied to a pixel circuit having at least a switching transistor connected to a signal line, a driving transistor connected to a light emitting element, and a current controlling transistor connected to the driving transistor in series. A reverse voltage applying circuit includes an analog switch or a clocked inverter, and a reverse voltage applying transistor which is turned ON when a reverse voltage is applied.
