Abstract
Display systems including novel Active Matrix Organic Light Emitting Diode (AMOLED) displays with controllable pixel-driver connections and the measuring of pixel voltage or current while controlling the controllable pixel-driver connections are disclosed. A single driver node is connected to a first node of a pixel, while a second connection from the single driver node to a second node of the pixel is disconnected using at least one peripheral controllable switch.
