Detailed explanation-1: -The Shadow Mask Method is commonly used in Raster-Scan System because it allows for the production of a much wider range of colors when compared to the beam-penetration method. Shadow Masks are used in the majority of TV sets and computer monitors.
Detailed explanation-2: -The shadow mask is one of the two technologies used in the manufacture of cathode-ray tube (CRT) televisions and computer monitors which produce clear, focused color images.
Detailed explanation-3: -Shadow Mask Technique in Computer Graphics is commonly used in raster-scan systems ( including color TV) because they produce a much wider range of colors than the Beam Penetration Method.
Detailed explanation-4: -In raster scan system electron beam sweeps across the screen, from top to bottom covering one row at a time. A pattern of illuminated pattern of spots is created by turning beam intensity on and off as it moves across each row. A memory area called refresh buffer or frame buffer stores picture definition.
Detailed explanation-5: -In which system, the Shadow mask methods are commonly used Raster-scan system uses shadow-mask method because they produce wide range of colors.
