Abstract
An organic light emitting display panel and a pixel compensation method are provided. The organic light emitting display panel includes: a pixel array including pixel regions divided into M rows and N columns; a plurality of pixel driving circuits, each includes a light emitting diode and a driving transistor for driving the light emitting diode, and the light emitting diodes are located in the pixel regions; and a plurality of pixel compensation circuits configured to sample an anode voltage of the light emitting diode are in at least one of the pixel driving circuits. A light emitting current flows through the light emitting diode, and generates a compensation signal based on the anode voltage and the light emitting current.
