Phosphors/ From Electrons to Digital Value

[Paolo Macachor]

Pardon me, but I'm a novice when it comes to techie stuff. Heck, all I know is how to run my videos through the IEEE 1394 and cut them in my NLE.... and print back to tape or burn to DVD. LoL

Anyway, are phosphors substances that can be commercially procured?

Also, can the process of how the electrons are turned into digital value (after light is emitted) from the pixels be explained? Unless I am required to take electronic and electrical engineering to understand (haha), I'll appreciate it if anyone enlightens me on my former question and perhaps explain to me (in lay man's terms) the process of this latter question.

Thanks!

geeze - I gotta ask, why do you want/need to know this?

[Paolo Macachor]

I just want to be enlightened on this. Or these, rather...

Are you talking about Phosphors as in the stuff inside a crt?

If you are the yes, some can be purchased through certain chemical dealers. Usually those that handle chemicals for universties and labs. Don't know any off the top of my head, and you likely won't find that latest blue light emitting phosphors may be company X. But older common stuff should be available

Phosphors emit light directly proportional (well, some what directly proportional) to the number of electrons that hit it. So your digital value will be turned into a small analog voltage, which in turn gets turned into a huge voltage (sometimes in excess of 30 000 volts) that sends electrons down a big vaccum tube where they hit the phosphors. The energy gained from the electrons hitting the phosphors bring the electrons at an atomic scale to a higher energy level, but they quickly fall back down to a normal state, and so have to lose energy, and electrons lose energy by releasing photons, which we percieve as visible light.

Hope that was the phosphors you were talking about

Yup. Gotta be it. Thanks! :)
