Abstract
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.
