Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting display panel and a driving method thereof. Background technique [0002] Organic light-emitting diodes, as a new generation of displays, have been favored by the industry in recent years. As a current-driven light-emitting element, the brightness uniformity of an organic light-emitting display panel is easily limited by factors such as threshold voltage drift of its own transistors and voltage drop caused by wiring resistance. [0003] Figure 1A It is a typical organic light emitting pixel circuit in the prior art, Figure 1B Is its corresponding working sequence diagram. Such as Figure 1A As shown, the pixel circuit includes a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a driving transistor T5, and a capacitor C st and light-emitting element D. Wherein, the gate of the first transistor T1 is connected to the fir...
