Abstract
An integrated driver for controlling operations of display systems having spatial light modulators that are operated in binary states is provided.
Claims5
A method for driving an array of micromirrors of a spatial light modulator used in a display system, wherein the spatial light modulator comprises an array of micromirrors, each of which being associated with an electrode of an array of electrodes, each electrode being connected a memory cell of an array of memory cells, the method comprising:
- connecting the memory cells to a first and second sets of wordlines such that, for a row of the memory cell array, the memory cells of the row are separately connected to at least a wordline from the first set and another wordline from the second set;
- connecting the each memory cells of a column to a bitline;
- upon receiving a display control signal and a set of data, generating a wordline control signal having a first value and a second value;
- activating the wordlines from the first set;
- delivering the data to the memory cells connected to the activated wordlines;
- deactivating the wordlines from the first set;
- activating wordlines from the second set;
- and
- delivering the data to the memory cells connected to the activated wordlines.

- connecting the each memory cells of a column to a bitline;
- upon receiving a display control signal;
- generating a wordline control signal that selectively activates and the deactivates the wordlines;
- updating the memory cells of a row, further comprising:
- loading a first set of data for the memory cells connected to the first wordline of the row;
- activating the first wordline delivering the first set of data to the memory cells connected to the activated first wordline;
- deactivating the first wordline;
- loading a second set of data for the memory cells connected to the second wordline;
- activating the second wordline;
- and
- delivering the data to the memory cells connected to the activated second wordline.
