Q. What is Shadow Mask?
Shadow Mask is a metal sheet that has fine perforations (holes) in it and is situated a short distance before phosphor coated screen. The Phosphor dots and holes in shadow mask are so organised that beams from a particular gun will strike dots of that colour only. The dots of other two colours are in the shadow. In an attempt to overcome some flaws of Shadow masks because of their round holes, Sony presented Aperture grills (in their Trinitron technology) which are slots in an array of vertically arranged wires.
