The Free On-line Dictionary of Computing (30 December 2018):

interlacing

   1.  A video display system which builds an image
   on the VDU in two phases, known as "fields", consisting of
   even and odd horizontal lines.

   The complete image (a "frame") is created by scanning an
   electron beam horizontally across the screen, starting at the
   top and moving down after each horizontal scan until the
   bottom of the screen is reached, at which point the scan
   starts again at the top.  On an interlaced display, even
   numbered scan lines are displayed in the first field and
   then odd numbered lines in the second field.

   For a given screen resolution, refresh rate (frames per
   second) and phosphor persistence, interlacing reduces
   flicker because the top and bottom of the screen are redrawn
   twice as often as if the scan simply proceded from top to
   bottom in a single vertical sweep.

   2.  progressive coding.
