Abstract
The present disclosure provides a driving circuit of a display device and the display device. The driving circuit includes an input unit, a control unit coupled to the input unit, and a light emitting unit coupled to the control unit. The control unit is configured to drive the light emitting unit to emit light. the control unit comprises a pulse width modulation (PWM) control unit and a pulse amplitude modulation (PAM) control unit, the PWM control unit and the PAM control unit are mutually independent, the PWM control unit is configured to control a light emitting time of the light emitting unit, and the PAM control unit is configured to control a magnitude of a driving current in the light emitting unit.
