 for bitmap display
From The Free On-line Dictionary of Computing (30 December 2018) :

  bitmap display
  bitmapped display
      A computer output device where each pixel
     displayed on the monitor screen corresponds directly to one
     or more bits in the computer's video memory.  Such a
     display can be updated extremely rapidly since changing a
     pixel involves only a single processor write to memory
     compared with a terminal or VDU connected via a serial
     line where the speed of the serial line limits the speed at
     which the display can be changed.
     Most modern personal computers and workstations have
     bitmap displays, allowing the efficient use of graphical user
     interfaces, interactive graphics and a choice of on-screen
     fonts.  Some more expensive systems still delegate graphics
     operations to dedicated hardware such as graphics
     The bitmap display might be traced back to the earliest days
     of computing when the Manchester University Mark I(?)
     computer, developed by F.C. Williams and T. Kilburn shortly
     after the Second World War.  This used a storage tube as its
     working memory.  Phosphor dots were used to store single
     bits of data which could be read by the user and interpreted
     as binary numbers.
     [Is this history correct?  Was it ever used to display
     "graphics"?  What was the resolution?]
