RE: More TFT Questions

Craplin sell them for.........

4.99 ;)

White Cold Cathode Flourescent Tubes. I have a green one and a blacklight
one here on my desk, which I intend to use for cool lighting effects...

They sell PSUs for them (12v in > 90V out) for £2.99

Might not be the right one, but could be!

Subject: [ukha_d] More TFT Questions


Bought a laptop with a dead screen off ebay to act as a firewall between my
lan and broadband.  And possibly as a low voltage web enabled HA box.  
When
I got the laptop the chap said that the screen did work but was really dim.
As I was planning to run netmeeting to access it I was quite happy to have
it with no screen but out of interest I whipped the screen apart carefully
to 'see how it worked'.  First I saw it was a good quality  12" TFT
screen..

Here I had a revalation.  Laptop screens have a lamp in them  (always
thought of the screen as LED, rather than LCD...)  Powered the screen back
on and looked closely and saw a perfect but unilluminated image.

Rooted about on the net for a few hours and found it could be the inverter
circuit or the lamp.  Then I found a stateside company that sold the lamps
for $9..  $25 shipping though.

So...  Anyone know a uk supplier of these laptop lamps..  Preferably one
that will accept none trade orders (or someone with a trade account at such
a supplier that'll put an order through for me).

I would order it from the states but am worried something so thin (3mm) and
delicate may not survive the journey..

Also not having a tft screen not attached to a laptop - which is cheaper to
run?  CRT or LCD?

Thanks
