Patent ID: 7459333

Claim:
A method, comprising: receiving a spatial light modulator and a control unit associated with the spatial light modulator for controlling the spatial light modulator; wherein the spatial light modulator comprises an array of reflective micromirror devices capable of modulating light; wherein the control unit is composed of a field-programmable-gate-array and lacks of an application-specific-integrated-circuit; and wherein the control unit comprises a data conversion module designated for converting a set of image data into a set of bitplane data, said module being implemented in the field-programmable-gate-array through a set of configuration data such that the field-programmable-gate-array is capable to output the bitplane data to the spatial light modulator; and building a projection system using the received spatial light modulator and control unit, further comprising: modifying the set of configuration data so as to modify a default configuration of the received control unit according to a desired specific configuration; and delivering the projection system to an end user.
