Abstract:
This disclosure provides systems, methods and apparatus for a display device incorporating high-speed data links. A display device can include a controller and a plurality of driver integrated circuits (ICs) for driving portions of a display panel. The controller can communicate data and control signals with the plurality of driver ICs over a plurality of links. The controller can adjust power consumed for communication over one link independently of the power consumed for communication over other links. The controller can adjust power consumed by the controller and a driver IC, as well as transmitter and receiver parameters to provide an acceptable quality of data transmission over the corresponding link. The controller can adjust the power consumed by adjusting a voltage swing of one or more transmission amplifiers and/or controlling the current supplied to receiver amplifiers of the driver ICs.
