Patent ID: 8446349

Claim:
A method for controlling the settings of respective arrays of light modulators of spatial light modulator devices for respectively modulating different colors in a multi-color display system using a single controller, comprising: at the controller, receiving an image input signal including color information of an image to be displayed; at the controller and based on the received image input signal, generating sequences of modulator settings data and reset signals for the different color modulations by the respective modulating devices, the data signals defining the settings to be used at a given reset time for the light modulators of a corresponding array, and the reset signals defining the given reset times for loading the settings from the data signals; and at the controller, generating a composite signal comprising time division multiplexing of the respective sequences of the modulator settings data and reset signals for the different color modulations; communicating the composite signal over a common communication link to the respective modulating devices; and loading the data to set the settings of each array for the color to be modulated by that array in coordination with the reset signals for that array according to the time division allocated for that array.
