Will LCoS projector with laser illumination source have spekcle?
LCoS is basically bunch of tiny mirrors for each pixel for forming an image with an external illumination source. With lasers as with LEDs the beam will need to be expanded, unlike a scanner based projector where the beam is thin.
In this case, will the image still appear wih speckle? Or will it be reduced due to the very wide laser beam and the micromirrors blocking parts of it?
My only concern is getting a 720p or even 4K video projector but the speckle ruining the high definition and completely discoloring some pixels.
