charactron การใช้

A much larger 19-inch diameter Charactron CRT was used for military radar-screen displays.
The Charactron CRT used an electron beam to flood a specially patterned perforated anode that contained the stencil patterns for each of the characters that it could form.
The technical expertise, and trademarks, for the Charactron ultimately passed to Stromberg-Carlson, General Dynamics, Stromberg DatagraphiX, Anacomp, and finally Lexel Imaging Systems.
The term Charactron is sometimes mistakenly applied to another type of CRT properly called a monoscope which generates an electrical signal by scanning an electron beam of uniform cross section across a printed pattern on an internal target electrode.
For example, the operator consoles of the CDC 6600 formed each letter all at once by sending the Charactron CRT electron beam through a metallic stencil mask with an A-shaped hole, or through a B-shaped hole, etc.
