The invention provides a printed circuit board and a detection method for detecting a connection between the printed circuit board and a flexible circuit board, and a display panel. The printed circuit board, through a connector provided thereon, is connected to a flexible circuit board, the printed circuit board is provided thereon with at least one first detection structure for matching with at least one second detection structure provided on the flexible circuit board, and whether or not a connection between the printed circuit board and the flexible circuit board is correct is determined by detecting matching between the first detection structures and the second detection structures. Pins of the printed circuit board may be correctly connected to pins of the flexible circuit board, and a case that short circuit occurs and thus the signal lines are damaged and burned can be avoided.

This invention provides a liquid crystal display panel, a source driver in the liquid crystal display panel comprises an amplifier whose amplification coefficient is adjustable, the amplifier can adjust a received data signal based on a currently selected amplification coefficient, and output the adjusted data signal to a data line that is currently signally-connected with the amplifier, moreover, the currently selected amplification coefficient is inversely proportional to a rate at which the data line charges a current signally-connected sub-pixel unit. For the case that the rate at which the data line charges the sub-pixel unit is relatively low, a relative large amplification coefficient can be selected, thereby nonuniform brightness of the display image caused by a low charging rate of the sub-pixel unit can be avoided; for the case that the rate at which the data line charges the sub-pixel unit is relatively high, a relatively small amplification coefficient is selected, thereby unnecessary power consumption can be saved. This invention further provides a display device comprising such a liquid crystal display panel and a driving method for use in such a liquid crystal display panel.
