An electronic device includes a first transistor, a second transistor, and a sensing circuit coupled to at least one of the first transistor and the second transistor. The sensing circuit includes a diode, a third transistor, and a fourth transistor. The diode has a first terminal. The third transistor has a first terminal and a second terminal. The first terminal of the third transistor is coupled to the first terminal of the diode. The fourth transistor has a first terminal coupled to the second terminal of the third transistor, and a second terminal coupled to a data driver.
