Enhanced Global Dimming for Projector Display Systems |
摘要 |
Projector display systems comprising a light dimmer and first modulator are disclosed. The light dimmer may comprise an adjustable iris, adjustable light sources and/or LCD stack that is capable of lowering the luminance of the light source illuminated the first modulator. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the light dimmer and first modulator. The display system may render a desired dynamic range for rendering a projected image by a combination of such control signals. |

1. 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 controller 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, causes the processor to perform the following instructions:
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; andsending 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. |
