A liquid crystal display (LCD) panel module and scan driver thereof is disclosed. The LCD panel module includes a LCD panel having data electrodes and scan electrodes, a scan driver and a data driver. The scan driver includes a timing controller, a scale-adjusting function circuit and an image gamma modulation circuit. The timing controller generates a first control signal and second control signal according to a first clock signal. The scan driver is controlled by the first control signal to drive the scan electrodes. The scale-adjusting function circuit adjusts an image scale corresponding to a first display signal and outputting a second display signal accordingly. The image gamma modulation circuit performs a gamma modulation on the second display signal to output a third display signal. The data driver, disposed on the LCD panel, drives the data electrodes to display pictures on the LCD panel according to the second control signal.
