System and method for driving LCD displays

A system for driving a liquid crystal display (LCD), having at least one segment, said system comprising:

• means for driving a segment of the LCD;
• and
• means for selecting any of at least two multiplexing modes, the at least two multiplexing modes producing at least three voltage levels for driving the at least one segment of the LCD.

A method for driving a liquid crystal display (LCD) having at least one segment, said method comprising:

• selecting any of at least two multiplexing modes;
• and
• initiating a signal having a predetermined duty cycle to drive the segment of the LCD based on the selected multiplexing mode.

A system for driving a liquid crystal display (LCD) having a segment including a first and second electrode, the system comprising:

• an LCD driver coupled to the first and second electrodes of the segment of the LCD;
• and
• a processor coupled to the LCD driver, the processor initiating a substantially periodic signal on the first electrode and a delay signal on the second electrode, the delay signal having a time delay relative to the substantially periodic signal, the signals on the first and second electrodes forming an RMS voltage to drive the segment of the LCD to any of at least three display levels.

A method for driving a liquid crystal display (LCD) having a segment including a first and a second electrode, the method comprising:

• applying a substantially periodic signal to the first electrode;
• and
• applying a delay signal to the second electrode, the delay signal having a time delay relative to the substantially periodic signal, the signals on the first and second electrodes forming an RMS voltage to drive the segment of the LCD to any of at least three display levels.

A system for driving a liquid crystal display (LCD) having a segment including a first and second electrode, the system comprising:

• means for driving the segment of the LCD;
• and
• means for initiating a substantially periodic signal on the first electrode and a delay signal on the second electrode, the signals on the first and second electrodes forming an RMS voltage to drive the segment of the LCD to any of at least three display levels.

A timekeeping device, comprising:

• a display area;
• and
• an LCD display having at least one segment located on said display area, the at least one segment being driven to one of at least three display levels.
