摘要： A display device having a frame period including reset, compensation, relay, emission, and initialization periods. Each pixel includes: an organic light emitting diode having an anode coupled to a second node and a electrode coupled to a second power source; a first transistor between a first power source and the second node, and a gate electrode coupled to a first node; a second transistor between the first node and the second node; a third transistor between the first power source and a third node; a fourth transistor between a fourth node and the third node; a fifth transistor between a data line and the fourth node; a sixth transistor between a third power source and the second node; a first capacitor between the third node and the first node; and a second capacitor coupled the fourth node and the third power source.
