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.
Claims17
A display system comprising:
- a plurality of pixels arranged in rows and columns;
- at least one driver for driving the plurality of pixels;
- a controller coupled to the at least one driver for controlling the at least one driver's driving of the plurality of pixels;
- a first signal line coupling a first node of a first pixel of the plurality of pixels to a node of the at least one driver;
- and
- a second signal line coupling a second node of the first pixel to the node of the at least one driver via a controllable switch coupled along the second signal line and located outside of the plurality of pixels, the controllable switch for coupling the second signal line to the node of the at least one driver and for decoupling the second signal line from the node of the at least one driver.
