  • Patent number: 7800571
    Abstract: A method for driving a dark ring of a liquid-crystal-on-silicon (LCOS) display is provided to prevent the fringe effect (bright lines) due to the constant voltage difference between the dark ring and the adjoining pixels within the LCOS display. A dark ring is divided into a plurality of portions. The polarity of each portion is controlled in accordance with the polarity of the adjoining pixels within the LCOS display and the scan direction of gate drivers such that the polarity inversion for each portion will coincide with that for the adjoining pixels within the LCOS display so as to avoid the fringe effect (bright lines).

  • Patent number: 7796558
    Abstract: The Inter-System handover is one of the key features in the third generation cellular systems. The compressed mode, with variable transmission gaps and power levels, is standardized to support the inter-frequency system handover. To minimize the use of system resources while maintaining the border-cell handover quality, a capacity-based compressed mode control method of the present invention is proposed. Considering the tradeoff between the capacity and the communication quality, the control method can adaptively manage the compressed mode operation based on the potential impacts on the capacity and the effectiveness of the compressed mode measurement. The present invention will improve the effectiveness and performance of the compressed mode operation.

  • Patent number: 7764255
    Abstract: The present invention relates to a LCOS display driving system. The driving sequential control block generates a control code representing a loading sequence of the R, G, and B data for pixels in one of scan lines. The multiplexer multiplexes the R, G, and B data from latches according the control code. The shared level shifter shifts the level of the R, G, and B data from the multiplexer. The digital analog converts converting the R, G, and B data to a corresponding analog R, G, and B data voltage. The shared unity-gain buffer stores the analog R, G, and B data voltage from the shared digital analog converter. The demultiplexer demultiplexes the analog R, G, and B data voltage according the control code.
