Abstract
A display device and a driving circuit thereof, and a driving method are provided, belonging to the field of display technologies. In the driving circuit, a light emission control sub-circuit may generate a driving signal and output the same from an output pin, so that a light-emitting unit group emits light based on the driving signal and a power supply signal provided by a power supply terminal. An amplification sub-circuit may amplify a reference power source signal provided by a reference power source terminal to have a voltage not less than a voltage of the power supply signal and transmit the amplified reference power source signal to a low-grayscale control sub-circuit. The low-grayscale control sub-circuit may control a connection and a disconnection between the amplification sub-circuit and the output pin under the control of an enabling control terminal.
