1. A method, comprising:
- controlling a display device in at least first mode by varying a correlation between display driver signals applied across display segments within the display device;
whereinthe display driver signals vary between substantially only two levels, and a display segment is activated when an average voltage magnitude across the segment over a time period exceeds a threshold value.

Abstract
A method may include controlling a display device in at least first mode by varying a correlation between display driver signals applied across display segments within the display device; wherein the display driver signals vary between substantially only two levels, and a display segment is activated when an average voltage magnitude across the segment over a time period exceeds a threshold value.

9. A method, comprising:
-
generating a plurality of time division multiplexed common driver signals and segment driver signals that vary substantially between only two levels; in a first mode, activating display segments by varying a correlation between common and segment driver signals connected to such display segments; and in a second mode, activating display segments by at least varying voltage levels of a common driver signal as received by the display segments. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system, comprising:
-
a first signal generator circuit that generates control signals that vary between substantially only two levels, and have predetermined correlations with respect to one another; and a selection driver circuit having at least a first mode that selectively couples selected controls signals to common display connection points, and couples selected control signals to segment connection points in response to at least display data;
whereina display segment connected between a common and segment connection point with signals above the minimum correlation will be activated. - View Dependent Claims (16, 17, 18, 19, 20)
