I am noticing a trend where laptops are offering LED backlit LCD-
displays instead of a fluorescent bulb. An LED display can add between
$100-$250 to the price of a laptop.
Sure, its a bit thinner, lighter and power frugal. But do LED displays
provide for a better quality viewing experience? Where is it wortht
the price difference.

I would not pay that much extra for it. I have not seen one, but I
question the difference in image quality. However, the difference in
power consumption (and hence battery life) is significant.

Just another selling point. The Led setup probably costs a fraction of
the old style, but the manufacturer still needs a gimmick.

No, at this time the LED backlight is a LOT more expensive, although in
time it will probably come down. It will be a LONG time before it's
cheaper, because CCFL tubes, in large volume, are extremely inexpensive.

too bad they dont pass those extremely inepensive prices to the

Remember that it costs $$$ just to generate a part number and catalog
it. Since they can't add that fixed dollar cost onto every part-- $20
for a rivet or small hinge --- they prorate it on the basis of actual
cost plus some algorithm that takes into account frequency of ordering
etc. etc. Thus, your $ 2.25 backlight inverter or CFL quickly grows to
$ 65.00. (Much like the Navy's $ 4000 toilet seat.)

Unless it's a generic part like a HDD, I usually opt to 'shoot old
paint' and go with a total replacement.

Fortunately with Thinkpads, I can buy a fairly good refurb, get
something more powerful than I had, probably a fresher battery and a
Windows update -- one stop shopping with no hassle. A local laptop
repair shop gets my left-over junk.

You can buy the CCFL tubes for about $8 to $16; now, as to the price of
an entire LCD panel, that's another matter. But we were only talking
about the backlight, not the entire display.

contacted a Haizhu District,Guangzhou China producer, (yes , that where
this stuff all seems to come from)

they make those HUGE side lighted panels for trade shows 6x 10 feet size,
using LED as illumnators (very impressive too!)

figured they would have this stuf down pat, and they DO!

but alas,as we all know, they also have the $$$$ down pat also! Chinese
are smart as wizards!

two strips, 310mm x 5mm x 5mm, 12vdc@340mA, white SMT with integrated
dropping R would still cost $30 (plus xtra Intl shipping!)

so another bright idea is shot to hel.......

UPS Int'l shipping isn't awefull, and if the Chinese offer anything
comparable to US Postal Service's International Priority Mail service
(small + light box, about US $10.00 to many countries -- delivery in
5-7 days), then US $40.00 wouldn't be bad to have the added battery
life [from LED-lit] to go with my VAIO's pretty-pretty X-Brite LCD
display. A lot of people like the non-glare LCD's, and for
readability in bright sunlight I did love my HP iPaq's trans-
reflective LCD, but if I'm not doing work on my VAIO then I'm watching
DVD's on it or reading e-books on it--indoors, out of the sun--and for
all of those tasks I prefer the crispness of X-Brite or Aquos to any
other LCDs I've seen so far; I seldom had problems reading it while
sitting on the front porch, either. The people who've said they don't
like the reflection off it [X-Brite / Aquos] in an office setting have
a valid point, I just don't use mine in those settings. For office /
travel I've got a long-in-tooth Dell C800 1 GHz P-III with two
extended-life batteries and docking station, and not because its
screen is less reflective (actually, even at its lowest intensity its
backlight leaves colors washed-out), but because I can use it 2-4
times as long between charging and it's much less flashy.

Anyway, back to topic and sorry if the digression offends: HapticZ,
I'm guessing the $30 is individual rate, but out of curiosity (and at
present, nothing more) did they happen to state their quantity rate
scale?

commercial bulk rates were avail on specific request.

once they figure out that anyone other than they themselves are making a
profit, they adjust the price upwards until they completely discourage small
buyers.

it's just another business strategy the Chinese have learned from the likes
of Walmart and their greedy buyers!

this global trade stuff is going to be uglyer and uglier as they deduce that
the usa people/manufacturers are so damn lazy they wont produce this stuff
themselves!
