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.

Abstract: A LED driving circuit comprises a high bit driving circuit, a low bit driving circuit and a driving output terminal. The high bit driving circuit coupled to a high bit signal of the grayscale signal determines a first current continuously driven during a grayscale period according to the value of the high bit signal. The first current is invariant during the grayscale period. The low bit driving circuit coupled to a low bit signal of the grayscale signal determines a second current driven in at least two time intervals during the grayscale period according to the value of the low bit signal. The driving output terminal coupled to the high bit driving circuit and the low bit driving circuit outputs the driving current added by the first current and the second current. Accordingly, the LED display can be improved with higher refresh rate and/or better uniformity in low grayscale.
