A liquid crystal display is provided with a plurality of display regions (1), a signal input module (2), a signal output module (3), and a signal comparison module (4). The signal input module (2) is electrically connected to the display regions (1), so as to import display driving signals to the display regions (1). The signal output module (3) is electrically connected to the display regions (1), so as to separately export output signal sources of the display driving signals at corresponding display regions (1) to generate a picture or an image. The signal comparison module (4) is electrically connected to the signal output module (3), so as to compare the output signal sources of the display regions (1); the output signals of display regions (1) are compared in the signal comparison module (4) to obtain a signal comparison result; when the output signal sources in two display regions (1) are different, currents of the display driving signals are adjusted correspondingly according to the difference of the output signals, so as to generate new output signal sources and output the new output signal sources to the display regions (1) for output display after differences between current values at the display regions (1) are continuously reduced, so that the brightness or the contrast of pictures or images displayed at the display regions (1) approaches to consistency. |
