- What Is DVST In Computer Graphics In HINDI | Direct View Storage Tube In Computer Graphics
DVST. (Direct View Storage Tube) An early graphics screen that maintained an image without refreshing. The entire screen had to be redrawn for any change.
the Direct View Storage Tube (DVST) behaves like a CRT with highly persistent phosphor. Pictures drawn on there will be seen for several minutes (40-50 minutes) before fading. It is similar to CRT as far as the electronic gun and phosphor-coated mechanisms are concerned. But instead of the electron beam directly writing the pictures on the phosphor coated CRT screen, the writing is done with the help of a fine-mesh wire grid.
The grid made of very thin, high quality wire, is located with a dielectric and is mounted just before the screen on the path of the electron beam from the gun. A pattern of positive charges is deposited on the grid and this pattern is transferred to the phosphor coated CRT by a continuous flood of electrons. This flood of electrons is produced by a "flood gun" (This is separate frame the electron gun that produces the main electron beam).
Just behind the storage mesh is a second grid called the collector. The function of the collector is to smooth out the flow of flood electrons. Since a large number of electrons are produced at high velocity by the flood gun, the collector grid, which is also negatively charged reduces, the acceleration on these electrons and the resulting low velocity flood pass through the collector and get attracted by the positively charged portions of the storage mesh (Since the electrons are negatively charged), but are repelled by the other portions of the mesh which are negatively charged (Note that the pattern of positive charges residing on the storage mesh actually defines the picture to be displayed).

Awesome sir... I always wanted to learn computer graphics from teachers like you
All the best
guy barely looks like a teacher, but explains things damn well and does it honestly.
An indian teacher need not wear suit boot to look like a teacher.
Thanks Sir for This Beautiful Explanation
Wahhhatt a explanation sirr hatsoff
very nice... pl. upload more on Computer Graphics..
Hats off to your efforts
Amazing explaination......
All the videos are very good and makes easy for us to study computer graphics but for some videos like this one the audio quality is very poor.
Sir plz NET ka syllabus cover kijjye....aapke lecture bahut helpful hain...
now i know dvst as well as how i can i sky rocket my carriers from buying pg diplomas from upgrad...coz too many adss!
