  • Patent number: 7928956
    Abstract: A digital controlled multi-light driving apparatus for driving and controlling a plurality of lights. The digital controlled multi-light driving apparatus includes a plurality of oscillation step-up circuits and a digital control circuit. The digital control circuit has a counter unit, a memory unit, a comparator unit, and a driving unit. The counter unit starts counting to generate a counting value whenever a digital start signal is generated. The memory unit stores at least one target counting value. The comparator unit is electrically connected to the counter unit and the memory unit to generate triggering signals whenever the counting value matches the target counting value. The driving unit is electrically connected to the comparator unit to output sequentially delayed driving signals to the oscillation step-up circuits respectively on receiving the triggering signals.

  • Patent number: 7760175
    Abstract: A method for driving an LCD includes a first brightness adjusting step and a second brightness adjusting step. In the first brightness adjusting step, the relative brightness of a plurality of light-emitting units is adjusted, so that the screen of the LCD presents a dark zone. The dark zone is caused by the brightness distribution of the light-emitting units and includes a scan line being activated. In the second brightness adjusting step, the relative brightness of the light-emitting units is readjusted after a specific scan timing. Therefore, the dark zone is shifted such that another scan line, which is being activated, is located in the shifted dark zone. Furthermore, a multi-light driving device and an LCD with the multi-light driving device and driven by the method are disclosed.
