Firstly, a number of scan signals are provided sequentially, and an enabling time of the scan signals excluding the last scan signal is adjusted according to a compensation time, so as to unfix the enabling time of these scan signals. Next, the scan signals having the unfixed enabling time are sequentially provided to an LCD panel, so as to turn on a number of row pixels of the LCD panel one by one. Thereby, the entire brightness of the LCD can be uniformed by applying the method disclosed in the present invention.
