Abstract

The present disclosure provides a driving circuit, comprising a plurality of transmission lines in one-to-one correspondence to a plurality of gate driving circuits and configured to transmit a control signal to the corresponding gate driving circuit; and a compensating resistor coupled to the corresponding transmission line so as to compensate for a resistance difference among the plurality of transmission lines.

Claims (11)

1. A method for implementing equal resistance of a plurality of transmission lines in one-to-one correspondence to a plurality of gate driving circuits and configured to transmit a control signal to the gate driving circuits, the method comprising:

coupling a zero-ohm resistor to each transmission line in advance;

acquiring a resistance value of each transmission line after the transmission lines have been prepared;

calculating a resistance value difference among the plurality of transmission lines; and

coupling a corresponding transmission line to a compensating resistor in accordance with the resistance value difference among the plurality of transmission lines to compensate for the resistance value difference among the plurality of transmission lines,

wherein the coupling the corresponding transmission line to the compensating resistor in accordance with the resistance difference among the plurality of transmission lines comprises:

replacing the zero-ohm resistor of the corresponding transmission line with the compensating resistor in accordance with the resistance difference among the plurality of transmission lines to compensate for the resistance difference among the plurality of transmission lines.

2. The method according to claim 1 , wherein

the transmission lines comprise connection gate lines through which a source driving circuit is coupled to each gate driving circuit, and

the resistance value of the transmission lines is a sum of the resistance of all connection gate lines on the transmission lines.

3. The method according to claim 1 , wherein the control signal is a Voff signal.
