Digital driving circuits, methods and systems for liquid crystal display devices
A method may include generating display driver signals that vary between only two levels and applying the display driver signals to opposing electrodes of a display segment within a display device. An intrinsic capacitance of the display device filters the display driver signals to generate different analog signal levels at the display segment of the display device.
