Abstract
Determining that a plurality of spatial light modulator (SLM) pixels includes one or more first regions of SLM pixels that satisfy an acceptable defective SLM pixel policy, and one or more second regions of SLM pixels that fail the policy, is disclosed. Utilizing the first regions of SLM pixels within a projection system that has a first resolution that is less than a second resolution that would have been provided by utilizing both the first regions of SLM pixels and the second regions of SLM pixels is also disclosed.
Claims55
A method comprising:
- determining that a plurality of spatial light modulator (SLM) pixels includes one or more first regions of SLM pixels that satisfy an acceptable defective SLM pixel policy and one or more second regions of SLM pixels that fail the acceptable defective SLM pixel policy;
- and,
- utilizing the one or more first regions of SLM pixels within a projection system having a first resolution that is less than a second resolution that utilizing both the one or more first regions of SLM pixels and the one or more second regions of SLM pixels would have provided.
An electronic device for utilization within a projection system comprising:
- one or more first regions of spatial light modulator (SLM) pixels that satisfy an acceptable defective SLM pixel policy and that are actively utilized to provide the projection system having a first resolution;
- one or more second regions of SLM pixels that fail the acceptable defective SLM pixel policy and that are non-utilized in providing the projection system having the first resolution;
- and,
- a memory to store locational information regarding at least one of the one or more first regions and the one or more second regions, wherein the one or more first regions of SLM pixels and the one or more second regions of SLM pixels when both utilized would otherwise provide the projection system with a second resolution greater than the first resolution.
A projection system comprising:
- a plurality of spatial light modulator (SLM) pixels including one or more first regions of SLM pixels that satisfy an acceptable defective SLM pixel policy and one or more second regions of SLM pixels that fail the acceptable defective SLM pixel policy;
- one or more light sources to output light for modulation by the plurality of SLM pixels;
- a projection optics mechanism to guide the light as reflected by the plurality of SLM pixels outward from the projection system;
- and,
- a controller to control the one or more first regions of SLM pixels in accordance with image data to realize a first resolution utilizing the one or more first regions of SLM pixels that is less than a second resolution that utilizing both the one or more first regions of SLM pixels and the one or more second regions of SLM pixels would have realized.
A projection system comprising:
- a plurality of spatial light modulator (SLM) pixels including one or more first regions of SLM pixels that satisfy an acceptable defective SLM pixel policy and one or more second regions of SLM pixels that fail the acceptable defective SLM pixel policy;
- one or more light sources to output light for reflection by the plurality of SLM pixels;
- a projection optics mechanism to guide the light as reflected by the plurality of SLM pixels from the projection system;
- and,
- means for controlling the one or more first regions of SLM pixels in accordance with image data to realize a first resolution utilizing the one or more first regions of SLM pixels and non-utilizing the one or more second regions of SLM pixels, wherein the one or more first regions of SLM pixels and the one or more second regions of SLM pixels when both utilized by the means would otherwise realize a second resolution greater than the first resolution.
