Abstract
A detection circuit, a driving circuit, and a display panel and a driving method therefor are provided. The detection circuit includes an acquisition circuit and a processing circuit. The acquisition circuit includes a test transistor and an energy storage element, where, for the test transistor, a control end is configured to be coupled to the data signal terminal, a first end is configured to be written with a detection signal, and a second end is coupled to the energy storage element; and a structural characteristic of the test transistor is identical to a structural characteristic of the driving transistor. The processing circuit is coupled to the second end of the test transistor, and configured to detect a voltage at the second end of the test transistor as a detection voltage and regulate the data signal according to the detection voltage.
