1. A method for controlling a spatial light modulator display system comprising:
- a. dividing the display system control, and data transfer functions into a data formatter controller to supply address and control signals to at least one data formatter, a memory controller to control at least one video memory, and a modulator controller to supply address and modulator control signals to at least one spatial light modulator; and
b. generating signals between said controllers to coordinate the addressing, reading, writing, and transferring of data between a data formatter, a memory, and a modulator, such that said transfers are done to provide said data and said modulator control signals to said modulator.

Abstract
A method and structure for providing system control to a spatial light modulator display are disclosed. The control functions are divided into smaller, easier to implement control blocks and coordination between them is provided. The smaller blocks are a memory controller, a modulator controller and a formatter controller.

7. A system controller for a spatial light modulator display system comprising:
-
a. a modulator controller to control at least one spatial light modulator; b. a memory controller to control at least one video memory; c. a formatter controller to supply address and control signals to at least one data formatter; d. signals between said modulator controller and said memory controller, between said modulator controller and said formatter controller, and between said memory controller and said formatter controller, to coordinate the operations of at least one formatter, at least one memory, and at least one modulator and to coordinate the transfers of data between said formatter, said memory, and said modulator, said operations and transfers performed to accurately represent a visual image upon said modulator. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
