Cathode Ray Tubes (CRT) were used in monitors (the non-flatscreen ones) which were common in older televisions.
It is used as the horizontal deflection voltage of the CRT.
AQUADAG is used in CRO for the collection of secondary electrons emitted from the inner CRT tube surface. It is actually a graphite(mild) coating on the inner side of CRT side walls for collecting secondary electrons so that the CRT do not get heated up due to the Collisions of those electrons at some other parts of CRT, there by preventing CRT from Thermal Runaway.
The CRO has nothing to do with the TV. IN CRO there is a Cathode Ray Tube(CRT) which is common in both CRO and TV. Earlier TV's with black/white picture had these type of CRT tube for generating the picture on the screen for viewing. But now a days these has been replaced by TFT, LCD any many such new technologies.
CRT PC monitors may appear old-fashion. They are finally being phased out. Their one major advantage is their price. One would find a high use of CRT monitors in developing countries simply because they are cheaper as compared to LCD monitors. One of the disadvantages of CRT monitors is that they are known to consume a lot of power. An advice offered today is to make sure they are completely turned off when not in use. The future looks dim for the old CRT. But for that second computer, it may still find some use.
Well, I am for one. I still have several old radios, phonographs, and a TV that use electron tube technology. It is the TV that uses the CRT picture tube of course. Except for the size, I prefer it to a flat screen for warmer colors. Other than myself, doctors use CRT in X-ray equipment, and some old radar may still use CRT's? Oscilloscopes if still out there would use CRT's in older models. So, the CRT is not dead yet...at least, no one told it.
Cro-magnon were a type of early human. The cro-magnon man hunted for his meals.
four parts of CRO: 1-crt 2-horizontal section 3-vertical section 4-power supply
CRT style televisions use an electromagnet, called the "Yoke", on the neck of the CRT in order to deflect the electron beam.
This is unknown.
Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.
CRT: Use more power, lower resolution LCD flat screen: price
