Abstract
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. The method varies the pulse density of the display driver signals to select or de-select the display segment based on an average voltage magnitude across the display segment over a time period. The display segment is activated when the average voltage magnitude exceeds a threshold value.
