摘要： A source driver circuit includes a receiver, a plurality of amplifying buffers, and a control logic circuit. The receiver receives a data signal and a control signal through an input terminal. Each of the amplifying buffers outputs a driving signal generated based on the image data signal through an output terminal. The control logic circuit controls the receiver and the plurality of amplifying buffers based on the control signal. When a power-down signal is provided to the receiver, the control logic circuit is to turn off at least one of the receiver and the plurality of amplifying buffers.

摘要： A dual-mode controller may include a communication interface between a handheld electronic device and subsystems on a computing bus or network. The dual-mode controller may operate in a “master mode” when a user directly manipulates the dual-mode controller to communicate with any subsystem(s). In this mode, the dual-mode controller may serve as a master controller and accesses and controls various subsystems on the bus or network (such as audio/visual subsystems, temperature control subsystems, alarm subsystems, sensors and transducers) as a master controller. In a slave mode, the interface may act as an adapter or interface between the handheld device and the subsystems.
