Abstract
Provided is an organic light-emitting display panel including: a first pixel driving circuit driving a first sub-pixel and including first driving transistors, and a second pixel driving circuit driving a second sub-pixel and including one or more second driving transistors. An operating current of the first sub-pixel at a preset grayscale is n times an operating current of the second sub-pixel at the preset grayscale, n≥1.5. The first driving transistor includes first and second driving sub-transistors. The first driving sub-transistor has a gate electrode electrically connected to a gate electrode of the second driving sub-transistor, a first electrode electrically connected to a first electrode of the second driving sub-transistor, and a second electrode electrically connected to a second electrode of the second driving sub-transistor. The number of the one or more second driving transistors is smaller than the number of the first driving transistors.
