  • Publication number: 20220238054
    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.
