1) Primary gun
2) Flood gun
basically this device is based on inherent image storage capability.plasma panel and laser scan display is based on this technology but DVST is most widely used in graphical displays
DVST stands for Direct View Storage Tube. It is one of the display devices in which an electron flood gun and writing gun is present. The flood gun floods electrons to a wire grid on which already the writing gun has written some image. The electrons from the flood gun will be repelled back by the negatively charged wire grid which has been charged so by the writing electron beam. The part of the wire grid which has not been charged -ve will allow the electrons to pass through and the electrons will collide on the screen and produce the image. Adv.-1)Refreshing CRT is not required. 2)Complex picture can be displayed in high resolution without flicker 3)It has flat screen

DIRECT VIEW TUBE CATHODE RAY TUBE dvst-1)it has flatscreen crt-1)it maybe ormaynotbe flat screen 2)it has poor contrast 2)better contrast then dvst 3)refreshing not allowed 3)refreshing allowed 4)selecting or part erasing of screen 4) in this erasing is allowed not allowed 5)performance is inferior to CRT 5)verybetter performance then DVST 6)high resolution for complex pictures
