dot pitch

dot pitch

   <hardware> The distance between a dot and the closest dot of
   the same colour (red, green or blue) on a color {CRT}.  Dot
   pitch is typically from 0.28 to 0.51 mm but large presentation
   monitors may go up to 1.0 mm.  The smaller the dot pitch, the
   crisper the image, 0.31 or less provides a sharp image,
   especially when displaying text.

   Dot pitch measurements between conventional tubes and {Sony}'s
   {Trinitron} tubes are roughly, but not exactly comparable.
   Sony's {CRTs} use vertical stripes, not dots, and its
   measurement is the distance between stripes, not the diagonal
   distance between dots.
