Abstract

The invention provides a driving circuit, a display device and a method for achieving equal resistance of multiple transmission lines. The driving circuit comprises the transmission lines which correspond to a plurality of grid driving circuits one to one and are used for transmitting control signals to the corresponding grid driving circuits and compensation resistors connected with the corresponding transmission lines so as to compensate resistance differences between the transmission lines. By the adoption of the scheme, the driving circuit, the display device and the method for achieving equal resistance of the multiple transmission lines can accurately achieve equal resistance of the transmission lines used for transmitting the preset control signals to the grid driving circuits.
