Abstract: A display system includes a display panel (200) having a full display screen area (303) upon which images can be generated for viewing. An image control circuit (400, 501) controls the operation of the display panel such that only a partial display field, or area, (305) is controlled to generate images in a first operating mode to conserve power and the full display screen area is controlled to generate images in a second operating mode.

Abstract: A multi-channel digital transceiver (400) receives uplink radio frequency signals and converts these signals to digital intermediate frequency signals. Digital signal processing, including a digital converter module (426), is employed to select digital intermediate frequency signals received at a plurality of antennas (412) and to convert these signals to baseband signals. The baseband signals are processed to recover a communication channel therefrom. Downlink baseband signals are also processed and digital signal processing within the digital converter module (426) up converters and modulates the downlink baseband signals to digital intermediate frequency signals. The digital intermediate frequency signals are converted to analog radio frequency signals, amplified and radiated from transmit antennas (420).

Abstract: To conserve power in a battery operated device such as a mobile telephone , a display system has two modes of operation, one in which only a partial display field is used to generate an image and another in which the an image is generated over the whole area of the display screen. The display system includes an image control circuit 400 comprising a pixel signal input 406, a FIFO memory 416 and a pixel fill circuit 418. The last named supplies a continuous stream of identical pixel signals each of which is capable of turning a pixel off. When the circuit is in partial display mode a combiner such as output switch 420 selectively combines pixel signals from the memory 416 with pixel off data from the pixel fill circuit 418 to produce a partial image. The display system may be part of a device moveable between open and closed positions, the partial image mode being activated in the closed position.
