Apple is taking an interesting approach toward improving the display performance of laser-based projection displays. The combination of less-coherent light sources with laser-based light sources can improve speckle performance, while reducing overall power consumption. Applications for this include traditional large-format projection, embedded projection, as well as for rear projection applications (such as televisions). Apple does not discuss any preferred method for generating the individual pixels of the image. Therefore, it appears that the patent application is broad enough to cover DLP, LCoS, or scanned mirror displays.
I don't see a need for such a technology right now. But considering it is Apple, fanboys will rush to the product and then "projecting" your laptop screen will be everywhere.
