摘要： Prior to increasing the voltage level of an input signal to be sampled in a step-by-step manner and writing a signal voltage Vsig at a desired voltage level, a precharge is performed which writes a precharge voltage Vpre, lower than the signal voltage Vsig, so as to apply the same voltage Vpre to the gate of a drive transistor in advance. This not only provides a reduced gate-to-source voltage of the drive transistor at the time of writing of the signal voltage Vsig but also extends a mobility correction time required for a mobility correction operation. The extension of the mobility correction time required for the mobility correction operation ensures a relatively smaller variation in the correction time, thus suppressing the variation in brightness. The extension also permits a write pulse to be set to the optimal pulse width.
