Abstract: A driving system includes a scan driving device. The scan driving device includes a configuration register, a counter, multiple comparators and a driver. The configuration register generates a counting parameter and multiple scan order parameters based on a serial input signal and a clock signal. The counter generates a counting value based on the clock signal, an enable signal and the counting parameter. Each comparator compares the counting value with a respective one of the scan order parameters to generate a comparison result. The driver generates multiple scan driving signals for driving a scan-type display based on the clock signal, on the enable signal and on the comparison results respectively generated by the comparators.

Abstract: A backlight driving method includes steps of: (A) receiving a piece of image data; (B) generating a piece of adjustment data based on the image data; (C) generating, based on a plurality of predetermined delay values and on an original synchronization control (SC) signal that has a pulse, an internal SC signal that has a plurality of pulses, where respective time delays of the pulses of the internal SC signal with respect to the pulse of the original SC signal are respectively dependent on the predetermined delay values; and (D) generating a backlight driving output based on the adjustment data and the internal SC signal, so as to drive a backlight source of a scan-type display to emit light intermittently.

Abstract: A backlight driving method includes steps of: (A) generating an original synchronization control (SC) signal, and a serial input signal that contains multiple predetermined delay values;
(B) generating multiple internal SC signals based on the original SC signal and the delay values, such that respective time delays of the internal SC signals with respect to the original SC signal are respectively dependent on the delay values;
and (C) generating multiple backlight driving outputs based on the internal SC signals to respectively drive multiple backlight sources, such that the backlight sources emit light in an order dependent on the delay values.
