Abstract

The invention discloses a signal transmission line structure and a display panel. The signal transmission line structure comprises: a first signal transmission line; a second signal transmission line;and a third signal transmission line. The third signal transmission line is connected with the first signal transmission channel in parallel, so that a second signal transmission channel with lower impedance can be formed; the display panel is provided with the signal transmission line structure, and impedance borne by transmission of all input signals in the display panel can be reduced to be balanced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of GOA drive technology, and in particular to a signal transmission line structure and a display panel. Background technique [0002] At present, most gate driving circuits of display panels use GOA (gate on array) circuits. The GOA circuit includes an input signal and multiple cascaded GOA unit circuits, and the input signal may include square wave signals such as scan start signals and clock signals. [0003] These square wave signals are transmitted from the outside of the display panel to the GOA circuit through corresponding wires, and the paths of these wires are different, resulting in different impedances of each wire, resulting in different input signals. , especially the impedance delay of each clock signal is different. [0004] The difference in impedance of the clock signal may easily cause a difference in the rising edge and / or falling edge of...
