摘要： 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.

摘要： A system and method for extracting a parasitic capacitance value from a pixel circuit including a light emitting device, a drive device to provide a programmable drive current to the light emitting device, a programming input, and a storage device to store a programming signal. The system and method determine the biasing voltage of an internal node of the pixel circuit during a driving cycle for a desired measurement level, and modify voltages of the pixel circuit that do not affect said biasing voltage to eliminate unwanted cross talk. In different implementations, the biasing voltage is determined by measuring the voltage at an internal node, or by calculating the voltage at the internal node.
