Single and multi-modulator projector systems with global dimming

A projector display system, said display system comprising:

• a light source;
• a controller;
• a light dimmer, said light dimmer being controlled by the controller to dim the amount of light from the light source;
• a first modulator, said first modulator being illuminated by light from said light dimmer and capable of modulating light from said light dimmer under control from the controller;
• said controller further comprising:
• a processor;
• a memory, said memory associated with said processor and said memory further comprising processor-readable instructions, such that when said processor reads the processor-readable instructions, the instructions cause the processor to perform the following steps:
• receiving image data, said image data comprising Enhanced Dynamic Range (EDR) image data;
• sending control signals to said light dimmer such that said light dimmer may allocate a desired proportion of the light from said light source onto said first modulator;
• and
• sending control signals to said first modulator such that said desired proportion of the light from said light source is modulated to form the desired screen image
• wherein the system further comprises:
• a set of colored laser light sources;
• for each color, a light conduit providing a light path for the corresponding colored light from said set of colored laser light sources;
• for each light conduit, an adjustable iris capable of adjusting the luminance of its associated colored laser light;
• and
• a light combiner, said light combiner capable of combining each said colored laser light passing through each associated adjustable iris
• wherein the system further comprises an integrating rod, said integrating rod accepting the combined light from all of the colored laser light sources and transmitting light to said first modulator.

A projector display system, said display system comprising:

• a light source;
• a controller;
• a light dimmer, said light dimmer being illuminated by said light source and said light dimmer being controlled by the controller to dim the amount of light from the light source;
• a first modulator, said first modulator being illuminated by light from said light dimmer and capable of modulating light from said light dimmer under control from the controller;
• a second modulator, said second modulator being illuminated by light from said first modulator and capable of modulating said light;
• said controller further comprising:
• a processor;
• a memory, said memory associated with said processor and said memory further comprising processor-readable instructions, such that when said processor reads the processor-readable instructions, the instructions cause the processor to perform the following steps:
• receiving image data, said image data comprising Enhanced Dynamic Range (EDR) image data;
• sending control signals to said light dimmer such that said light dimmer may allocate a desired proportion of the light from said light source onto said first modulator;
• and
• sending control signals to said first modulator and to said second modulator such that said desired proportion of the light from said light source is modulated to form the desired screen image.
