Abstract: A signal transmission structure includes a driving circuit block, a receiving circuit block, a main transmission line, and a copper patch. The main transmission line connects the driving circuit block to the receiving circuit block for transmitting signals therebetween. The copper patch is arranged at the main transmission line, and has a rectangular shape. The copper patch can reduce switching rates when the signal state of the driving circuit changes rapidly. The copper patch serves as a compensation capacitor, to reduce a rate of switching of the signal, and to reduce or even eliminate the problems of crosstalk and overshooting and undershooting of signals. It is of advantage that the copper patch is simple to manufacture and very suitable for mass production.
