- noun a special CRT used for computer graphics, which retains an image on screen without the need for refresh actions
- A CRT whose high-intensity display is the result of secondary emissions of electrons. Such a display remains bright for controllable periods of time, and may be used, for instance, in radars. The displayed image is formed by a writing gun and intensified by a flooding gun. Also called storage CRT, storage cathode ray tube, or direct-view storage tube.
