Abstract
An aging detection circuit, an aging compensation circuit, a display panel, and an aging compensation method are provided. The aging detection circuit includes: a first current mirror circuit, a second current mirror circuit, a voltage converter and an analog-digital converter. An input terminal of the first current mirror circuit is electrically coupled to an initial reference voltage terminal and an anode of a to-be-detected light-emitting diode respectively, and an output terminal of the first current mirror circuit is electrically coupled to an input terminal of the second current mirror circuit. An output terminal of the second current mirror circuit is electrically coupled to an input terminal of the voltage converter.
