Abstract
A driver is configured to maintain a threshold compensation transistor to be ON to write a threshold compensation voltage to a storage capacitor in a threshold compensation period, and write a data signal to the storage capacitor in a data write period after the threshold compensation period. A pulse width of control signal is twice or more as long as the data write period. The driver circuit is configured to turn ON a first transistor with a start edge of a first control signal pulse before the data write period starts, maintain the first transistor to be ON and turn ON a second transistor with a start edge of a second control signal pulse to start the data write period, and turn OFF the first transistor with an end edge of the first control signal pulse to end the data write period.
