Pixel circuit and display apparatus including the same
A pixel circuit includes a first transistor that supplies a data signal to a first node in response to a scan signal. The pixel circuit may also include a capacitor that is connected between the first node and a ground voltage and a detecting unit that is connected in parallel with the capacitor. More so, the detecting unit may change a voltage of the first node by being activated in response to a mode signal. Also, the detecting unit may have resistance that varies according to an external stimulus. The pixel circuit may also include a second transistor that is complementarily activated with respect to the detecting unit in response to the mode signal, and that provides a voltage of the first node.
