Abstract:
A method of driving a display panel includes: correcting a gate-source voltage of a first transistor to cause the gate-source voltage of a first transistor to become closer to a threshold voltage of the first transistor; and writing a signal voltage into a gate of the first transistor by applying a plurality of voltage pulses to a gate of a second transistor. The correcting and the writing are performed in each of pixels of the display panel. The signal voltage corresponds to an image signal. The voltage pulses applied in the writing include a first voltage pulse and a second voltage pulse. The first voltage pulse is applied previous to the second voltage pulse. The second voltage pulse is applied subsequent to the first voltage pulse. A peak value of the first voltage pulse is higher than a peak value of the second voltage pulse.
