Abstract
A driving device is used to control pixels of a pixel array. The driving device includes driving circuits. Each driving circuit includes a pulse width modulation circuit, which is used to provide an output pulse signal to at least one of the pixels of the pixel array, and a shift control circuit, which is used to provide a shift pulse signal to the pulse width modulation circuit and the shift control circuit of a next stage. The output pulse signal has an output pulse width. The shift pulse signal has a shift pulse width, which is substantially equal to a first period of a first clock signal or a second period of a second clock signal. The first period is equal to the second period. The pulse width modulation circuit modulates the output pulse width in response to the shift pulse signal, a data signal and a sweep signal.
