Abstract:
1. A driving circuit, comprising: a first PWM driving module, generating a first square-wave signal to drive a first illumination unit according to a first data signal of a data stream, wherein the first square-wave signal represents an illumination period of the first illumination unit in a display cycle, and a rising edge of the first square-wave signal is located at the beginning of the display cycle, wherein a first register unit receives the first data signal and outputs the first data signal to the first PWM driving module; and a second PWM driving module, generating a second square-wave signal to drive a second illumination unit according to a second data signal of the data stream, wherein the second square-wave signal represents an illumination period of the second illumination unit in the display cycle, and a falling edge of the second square-wave signal is located at the end of the display cycle, and wherein a rising edge of the second square-wave signal is behind the rising edge of the first square-wave signal, wherein a second register unit receives the second data signal and outputs the second data signal to the second PWM driving module.
