About how much zinc is used in your average television screen and how does it work?

Question

I know televisions come in all shapes and sizes, so I mostly mean the average one in most people's houses. I'd like it if you gave it to me in ounces, but whatever you weigh it in doesn't matter really. I can do the math later.

Answer 1

Form the way you state the question, I'd guess you mean the phosphors in the screen, which is something I don't know anything about, but I would guess it is a small fraction of an ounce, the phosphor coating is not very thick, and other elements are used in addition to zinc, Zinc seems to be a component of the blue phosphor (see "sources" below), but again I doubt the weight is very much.

If you mean all the zinc used in all the parts of the set, it gets hard to come up with average, some parts may be zinc plated, but again that won't amount to much weight because the coating is thin. Zinc is a common component of die casting alloys and there _could_ be a fair bit of weight in die cast parts, but most modern sets are probably more likely to have plastic, so it is very hard to say.

Answer 2

I can tell you how a television works in terms of three signals. Signal #1 is sound

Signal#2 tells each pixel what color tubes to excite to create color

Signal #3 controls the brightness of a pixel.
