Abstract
A driving circuit for driving a light emitting unit includes a gray scale generation circuit and a driving unit, and a gray scale generation circuit, includes a shift register unit and a data storage unit. The shift register unit receives a luminance-related data, and the shift register unit is a k-bit shift register unit. The data storage unit has parallel input ends and a serial output end. The data storage unit receives the luminance-related data via its parallel input ends and serially outputs bits of the luminance-related data to generate a serial signal. The data storage unit determines time points to output different bits of the serial signal to generate a gray-scale control signal according to a serial-out control signal. The driving unit is coupled to the gray scale generation circuit to adjust a light-emitting time of the light emitting unit according to the gray-scale control signal.
