Optionally the pre-stored high-voltage signal received by the pixel circuit in the preceding frame is a detected high-voltage signal received at the first electrode of the driver transistor in the pixel circuit in the preceding frame when the light-emitting element in the pixel circuit was emitting light in the preceding frame. In the compensation method according to the embodiment of the disclosure, after the high-voltage signal received at the first electrode of the driver transistor in the pixel circuit in the current frame is detected, and before the compensation voltage corresponding to the pixel circuit is determined, the method can further include the following step.

The detected high-voltage signal received at the first electrode of the driver transistor in the pixel circuit in the current frame is stored.

In the organic light-emitting display panel, an element generating a high-voltage signal is generally a VDD power source. Since the VDD power source is connected respectively with pixel circuits in the organic light-emitting display panel through signal lines, and the signal lines have resistances, there is an IR drop for each of the high-voltage signals received by the pixel circuits.

Accordingly optionally in the compensation method according to the embodiment of the disclosure, there may be a plurality of pixel circuits in a display area of the organic light-emitting display panel. As illustrated in FIG. 2, the compensation method can specifically include the following steps.

The step S201 is to detect corresponding high-voltage signal received at a first electrode of a driver transistor in each of the pixel circuits in the organic light-emitting diode display panel in the current frame when a light-emitting element in each of the pixel circuits is emitting light.
