Accordingly, no voltage compensation may be performed on the pixel circuit with the smaller IR drop to thereby further lower power consumption.

Optionally in the compensation method according to the embodiment of the disclosure, a display area of the organic light-emitting display panel may include a plurality of display sub-areas, and there may be at least one pixel circuit in each display sub-area. Before the high-voltage signal received at the first electrode of the driver transistor in the pixel circuit is detected, the compensation method can further include the following steps.

An IR drop corresponding to each of the display sub-areas is determined.

For each of the display sub-areas, when the IR drop, corresponding to the display sub-area, lies out of a preset drop range, the display sub-area corresponding to the IR drop lying out of the preset drop range is determined as a display sub-area to be compensated.

Detecting the high-voltage signal received at the first electrode of the driver transistor in a pixel circuit in the organic light-emitting diode display panel in the current frame when the light-emitting element in the pixel circuit is emitting light can specifically include the following step.

Detecting the high-voltage signal received at the first electrode of the driver transistor in each of the at least one pixel circuit in the display sub-area to be compensated, in the current frame when the light-emitting element in each of the at least one pixel circuit in the display sub-area to be compensated are emitting light.
