Abstract: A driving circuit for a display panel is disclosed. The driving circuit includes at least a driving signal line connected to a display driving signal transmission unit delivering display driving signal produced by the display driving signal transmission unit to sub-pixels of the display panel through the driving signal line; and a number of data signal lines connected to a display data provision unit delivering display data signal produced by the display data provision unit to the sub-pixels. For each subset of the sub-pixels that are of a same component color, at least two data signal lines, starting from different points of time, deliver display data signal to the subset of sub-pixels that are of the same component color. The driving circuit effectively resolves glitches to input signal resulted from heavy transient load to the input signal.

Abstract: A signal switching device and a test system are disclosed. A printed wire which is connected with a test circuit can be selected flexibly according to actual situation, and a sufficient distance between adjacent tested printed wires/test printed wires which are used for transmitting a differential signal can be maintained, such that signal interference between the printed wires would not be easily generated. Signals can be effectively separated from each other, and thus the technical problem that signal interference would easily be generated between adjacent tested printed wires/test printed wires which are used for transmitting a differential signal can be solved.
