US Patent:

20110169814, Jul 14, 2011

Filed:

Jan 14, 2011

Appl. No.:

13/007014

Inventors:

David Van Ess - Chandler AZ, US
Christopher C. Keeser - Everett WA, US
Robert L. Murphy - Seattle WA, US
David G. Wright - San Diego CA, US

Assignee:

CYPRESS SEMICONDUCTOR CORPORATION - San Jose CA

International Classification:

G09G 3/36
G09G 5/00

US Classification:

345212, 345 87

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.

International Classification:

G09G 3/36

US Classification:

345212

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. The method varies a correlation between 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.
