1. A display panel, comprising:
first sub-pixels, wherein at least one of the first sub-pixels comprises a first pixel circuit and a first light-emitting element, the first pixel circuit comprises a display controller and a detector that are electrically connected to a first electrode of the first light-emitting element, respectively;
wherein an operating process of the first pixel circuit comprises a detection stage, and wherein during the detection stage the detector is turned on to detect a voltage of the first electrode of the first light-emitting element;
wherein the display panel has a first mode comprising a first data refreshing frequency and a second mode comprising a second data refreshing frequency, wherein the first data refreshing frequency is smaller than or equal to the second data refreshing frequency;
a frequency at which the detector detects the voltage of the first electrode of the first light-emitting element is greater than or equal to the first data refreshing frequency, and smaller than or equal to the second data refreshing frequency; or
the display panel has a first mode comprising a first data refreshing frequency and a second mode comprising a second data refreshing frequency, wherein the first data refreshing frequency is smaller than or equal to the second data refreshing frequency; and
a duration of the detection stage in the first mode is greater than a duration of the detection stage in the second mode.
