ABSTRACT:
A driving-control device of a backlight module receives a first digital burst signal and includes a start signal generating unit, a counter unit, a memory unit, a comparator unit and a driving unit. The start signal generating, unit generates a digital start signal on receiving the first digital burst signal. The counter unit is electrically connected to the start signal generating unit and sequentially generates counting values on receiving the digital start signal. The memory unit stores at least one target counting value. The comparator unit is electrically connected to the counter unit and the memory unit and sequentially generates triggering signals according to the counting values and the target counting value. The driving unit is electrically connected to the comparator unit and outputs sequentially delayed driving signals on receiving the triggering signals.
