Hi oiseautempete
it's been almost 10 years that I have a screen consuming 22W (against 2VA of the previous one)
I've been saving 10W per hour of use for 420 years
a cathodic works on the principle
arc lamp or electric welding
just like fluorescence, so lots of UVs.
image is unstable due to scanning of the electron gun
for now there is only the LED which produces light, only in the visible spectrum
What to pay me for, a 300-euro LED LCD screen at 2 hours a day
economics
with the money of the butter
goodbye Hic
Sorry, but, I do not understand your explanations and we are obviously not talking about the same thing, with 22w, your screen is a 15 inch PC screen and 10 years ago the image quality of LCDs was "at take a dump"...
a Sony TV screen 100hz 117cm (46 inch) 46x4500 type it costs ~ 2400 € (public price) ... mine (46z5500 with backlighting HCFL tubes cold cathode low consumption) it was 2000 € public price (but I got it at 1700 € with a good discount)
