    摘要: This disclosure provides systems, methods, and apparatus for providing a cascode driver circuit for providing positive and negative polarities of two or more voltages at an output node. The voltages provided by the cascode driver circuit can be used to provide voltages to various interconnects and terminals of the display apparatus. The cascode driver circuit includes a first circuit for providing a positive polarity of two or more voltages to an output node via a first set of cascode transistors and a second circuit for providing negative polarities of the two or more voltages via a second set of cascode transistors. The driver circuit includes body-effect mitigation circuitry for reducing the impact of body-effect on the performance of the driver circuit. The driver circuit also includes circuitry for reducing substrate leakage current.

    摘要: 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.
