ABSTRACT:
A method for sensing a light emissive element in an active matrix display pixel cell further including a data line connectable to a drive element and to a first electrode of the emissive element. The data line is connected to the anode of the emissive element, and a sensing voltage to reverse bias the emissive element, and detecting any leakage current flowing through the emissive element.
