Abstract: The present invention discloses a test connector, a transmission wire, a test system, and a using method. A test connector for a low voltage differential signal transmission wire comprises a signal wire interface matching with the low voltage differential signal transmission wire, and a PCB interface matching with a PCB plate to be tested, and the signal wire interface is electrically connected with the PCB interface. In the present invention, the test connector is inserted or pulled instead of a low voltage differential signal transmission (LVDS) connection; when damaged, only the test connector needs to be replaced, and the service life of the low voltage differential signal transmission (LVDS) wire is extended greatly. Because the cost of the test connector is only less than 10% of that of the LVDS wire, loss cost can be reduced.

Abstract: A driving circuit for a LED backlight module includes a brightness adjusting module, a current detector, a reference voltage adjusting module, and a comparing module. The current detector is capable of detecting the current of the brightness adjusting module and outputting a detecting result. The reference voltage adjusting module is capable of choosing the corresponding reference voltage corresponding to the detecting result of the current detector. Thus, the reference voltage outputted to the comparing module can be adjusted according to the change of the current of the brightness adjusting module. This reduces the power consumption and the amount of heat generated due to the power consumption, and improves the performance of the LED backlight module.

Abstract: The present disclosure discloses a liquid crystal module and a liquid crystal display. The liquid crystal module includes a plastic frame, a front frame as well as a liquid crystal display panel positioned therebetween. The front frame is a square frame made of a sheet formed by vacuum molding. The front frame and the plastic frame are cooperated with each other in order to fix the liquid crystal display panel. The front frame includes an elastic buckling part/elastic clamping buckle, and the plastic frame includes a clamping buckle/buckling part being interference fit with the elastic buckling part/elastic clamping buckle for fixing the liquid crystal display panel. The front frame of the present disclosure, shortens the developing period so as to reduce the cost for opening module of the liquid crystal module and further reduce the manufacturing cost of the liquid crystal display.
