摘要： A system and method for driving a liquid crystal display (LCD) having at least one segment. The system includes an LCD driver connected to a segment of the LCD. A processor is connected to the LCD driver. The processor may be selectively configured into any of at least two multiplexing modes, where the at least two multiplexing modes produce at least three voltage levels for driving the at least one segment of the LCD. Another embodiment includes a system and method for driving an LCD having a segment including a first and second electrode. An LCD driver is coupled to the first and second electrode. A processor is coupled the LCD driver. The processor initiates a substantially periodic signal on the first electrode and a delay signal having a time delay relative to the substantially periodic signal. The signals on the first and second electrodes form an RMS voltage to drive the segment of the LCD to any of at least three display voltage levels.
