Abstract
A system and method for staggered actuation of columns of interferometric modulators. In one embodiment, the method determines data for actuating two or more groups of columns in the array, each group having one or more columns, and provides the data to the array to actuate two or more group of columns so that each group is activated during a group addressing period. In another embodiment, a display includes at least one driving circuit and an array comprising a plurality of interferometric modulators disposed in a plurality of columns and rows, said array being configured to be driven by said driving circuit which is configured to stagger the actuation of the plurality of columns during an array addressing period.

15. A display, comprising:
-
at least one driving circuit; and
an array comprising a plurality of columns of interferometric modulators and a plurality of rows of interferometric modulators, said array being configured to be driven by said driving circuit, wherein said driving circuit is configured to receive column data for the plurality of columns, and is further configured to use the column data to non-simultaneously assert a signal on each of two or more columns of interferometric modulators during a column addressing period and to assert a signal on each of one or more rows during a row addressing period.

16. A method of providing data to an array having a plurality of columns of interferometric modulators and rows of interferometric modulators, the method comprising:
-
asserting a signal for each of the columns in the first group of columns based on a first data set during a first group addressing period in an array addressing period;
asserting a signal for each of the columns in the second group of columns using a second data set during a second group addressing period in the array addressing period, the second group addressing period overlapping the first group addressing period during a portion of time; and
asserting a signal in a first row during the portion of time to actuate interferometric modulators in the first row. - View Dependent Claims (17, 18, 19, 20)

21. A method of providing data to an array having a plurality of columns of interferometric modulators and rows of interferometric modulators, the method comprising:
-
receiving data for two or more groups of columns in the array, each group having one or more columns; and
asserting signals based on the data to the two or more groups such that signals are asserted on two or more groups beginning at different times and there is a period of time when signals are asserted on all the groups at the same time. - View Dependent Claims (22, 23, 24, 25, 26)

27. A display, comprising:
-
an array comprising a plurality of interferometric modulators, each of the interferometric modulators being connected to a column electrode and a row electrode; and
a driving circuit connected to the column electrodes and row electrodes of said array and being configured to drive the array, said driving circuit configured to assert a signal on two or more columns beginning at two different times.

28. A driver circuit configured to drive an array of a plurality of interferometric modulators, each of the interferometric modulators being connected to a column electrode and a row electrode, the driving circuit comprising:
-
a storage device to store predetermined display data; and
a signal device in data communication with said storage device, said signal device configured to assert a signal on each column electrode of two or more columns non-simultaneously, wherein the signals are based on the predetermined display data.
