lcd brightness modification?

**theomms** · 02-12-2004, 06:26 AM

from reading other threads it is my understanding that the brigthness of an lcd is determined by the ccfl (cold cathode flourescent lights) that backlight the tft.

is that true?

if that is true then is it possible to make an lcd brighter by changing or adding more ccfl backlighting?

source for cold cathodes and inverters

I was tooling around on google and found this... I dunno exactly what they do to achieve a brighter display but you could email them about it I guess.

"ultrabright option for all xenarc tft lcd monitors"

yes please email and keep us posted

This is the regular modification done by Xenarc. It is near the bottom of the page.

think it'll work with the lilliput?

They change the screen, you have to send it in. I don't think that they will take a Liliput. They don't even take Gain (Xenarc) screens bought at an unauthorized dealer.

Hmm... they also mention that they put an anti-reflective coating on the screen when you order the ultrabrightness option. I dunno if it's all worth an additional $195 but it looks promising if you can get a good deal on your xenarc.

thanks for the replies

but what do you guys think?

are they just adding more lights? or are they changing the light that is already in there to a different brighter one? or are changing the inverter to one that has higher voltage output?

Any or all of the above, I'd say.

I'm no expert, but as I understand it, the LCD has to have enough contrast ratio for the extra light. Too much light with a weak contrast ratio, and you can't display black anymore.
