How to increase lamp brightness?

[wush]

Hi,

How to increase the overall lcd lamp brightness...
Well is it possible to get 400 cd/m from 250 cd/m generating lcd lamp on
classic 15" tft?
Thing is I need to boost brightness for high daylight indoor places.
I am now using 800 cd/m industrial displays that have really high price.
I know that lamp life will be very short, but 5000h is ok for us.

If you have any idea how this can be done...
Please help me out. Thanks!

Regards,
Wush

On some backlight inverters (which is what powers the lamp) there are
controls for a 'boost' mode of operation. This *does* shorten the life
od the backlight - you would need to look at the data for your
particular LCD.

For instance, see the MicroSemi offerings

They have controllers and inverters.
