A dot-matrix display data refresh charging/discharging control method and system is proposed, which is designed for integration to a dot-matrix display device for providing a data refresh charging/discharging control mechanism on the dot-matrix display device. The proposed method and system is characterized by the capability of prior to a data refresh action on each pixel, switching the pixel for connection to a voltage-neutralizing point for the purpose of neutralizing the current data voltage charge on the pixel to substantially approach zero voltage level; and subsequently during the data refresh action, charging a new data voltage into the pixel. This feature allows the operation of the dot-matrix display device to have faster speed and low power consumption.
