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.

Abstract: A controlling method of decreasing a power consumption of a liquid crystal display module is described. The method provides steps of: increasing a voltage loading between two ends of liquid crystals and decreasing a back light driving current when a video image enable signal is within an image disable region, so as to keep the liquid crystal display module having a constant brightness. According to the controlling method, the voltage loading between two ends of the liquid crystal is increased when the video image enable signal is in the image disable region, so as to raise a light transmittance as the liquid crystal pixel works, raise a display brightness of the liquid crystal panel, decrease the back light driving current, reduce a back light brightness and ensure an entire display effect being constant when the video image enable signal is in the image disable region.
