Abstract

An organic light-emitting display panel includes: pixel rows arranged sequentially along a first direction and high voltage signal lines extending along the first direction. Each pixel row includes pixel sets arranged along a second direction which intersects the first direction. Each pixel set includes first and second pixels arranged along the second direction. The first pixel includes first to third sub-pixels emitting different colors. The second pixel includes fourth to sixth sub-pixels emitting different colors. Each sub-pixel includes a pixel driving circuit and an organic light-emitting diode. The high voltage signal lines are electrically connected to the sub-pixels, so as to provide voltage signals to anodes of the organic light-emitting diodes for driving the sub-pixels to emit light. For the same pixel set, the third and fourth sub-pixels have the same color, and are electrically connected to the same third high voltage signal line.
