Abstract

The present invention provides a device comprising: a backplane controller including means for sequencing a series of instructions, wherein the instructions control memory accesses to data that is used to control one or more pulse widths that drive one or more mirrors/electrodes on a spatial light modulator that control one or more outputs of the spatial light modulator.

Claims

1. A device comprising:

a backplane controller including means for sequencing a series of instructions, wherein said instructions control memory accesses to data that is used to control one or more pulse widths that drive one or more mirrors/electrodes on a spatial light modulator that control one or more outputs of the spatial light modulator.

2. The device of claim 1, wherein said device further includes memory in which said instructions are stored.

3. The device of claim 2, wherein said memory is RAM.

4. The device of claim 1, wherein said instructions control which of said data is accessed.

5. The device of claim 1, wherein said instructions control which drive bits of said spatial light modulator are enabled to be modified.
