DISPLAY DEVICE AND DRIVING CIRCUIT THEREOF, AND DRIVING METHOD

Provided are a display device and a driving circuit thereof, and a driving method, relating to the technical field of displays. In the driving circuit, a light-emitting control sub-circuit can generate a driving signal to be output from an output pin, such that a light-emitting unit group emits light on the basis of the driving signal and a power supply source signal provided by a power supply source terminal. An amplification sub-circuit can amplify the potential of a reference power supply signal provided by a reference power supply terminal to a potential not less than the potential of the power supply source signal, and then transmit same to a low grayscale control sub-circuit. The low grayscale control sub-circuit can be controlled by an enable control terminal to control the amplification sub-circuit and the output pin to turn on or off. In this way, signals provided by the enable control terminal can be flexibly configured such that when a light-emitting plate comprising the light-emitting unit group e
