The invention discloses a display device and a driving method. The display device comprises a plurality of light-emitting elements and a plurality of driving circuits. Each of the plurality of driving circuits is used for generating a driving current to drive one of the light-emitting elements to emit light. Each of the plurality of driving circuits includes a first transistor, a second transistor, a reset circuit, a first control circuit, and a second control circuit. The driving current flows through one of the first transistor, the second transistor and the plurality of light-emitting elements from the first system high voltage end to the system low voltage end. The first control circuit is used for controlling the first transistor to modulate the pulse amplitude of the driving current. The second control circuit is used for controlling the second transistor to modulate the pulse width of the driving current. 一种显示装置及驱动方法，显示装置包含多个发光元件以及多个驱动电路。多个驱动电路各自用以产生驱动电流以驱动该些发光元件其中一者发光。多个驱动电路各自包含第一晶体管、第二晶体管、重置电路、第一控制电路
