PIXEL, ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE, AND ITS DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To display an image at uniform luminance.

SOLUTION: A pixel comprises: an organic light-emitting diode OLED; a second transistor M2 for controlling the amount of current flowing to a second power supply ELVSS via the organic light-emitting diode OLED from a first power supply ELVDD; and a third transistor M3 connected between a gate electrode of the second transistor M2 and a bias power supply and turned on when a reset signal is supplied to a reset line Rn. The time when the third transistor M3 is turned on is determined so that the voltage of the bias power supply Vbias is applied to the gate electrode of the second transistor M2 for 560 μs or more.
