Why light from TV’s display doesn’t project it’s image on surfaces like projector?
In: Physics
A projector sends light rays in such a way that light corresponding to a single pixel only goes in the direction where that pixel would be on the surface. So, each point of the surface is only lit with the light from one pixel allowing you to see the projected image.
A display has all pixels shining in every direction. This means that any point of the surface will be lit by the light from all pixels, that doesn’t produce an image but allows you (when the said surface is your eye) to see entire image on the monitor.
