Help choosing a Backlight WLED Driver for a 7" LCD

I've been looking for a constant current WLED driver to power up the backlight of a 7" LCD.I've gone through the datasheets of most of TI and some other manufacturers' drivers but they're only capable of driving UP TO to some ammount of LEDs (Typically 6-10) in series or some other configuration like 9 Strings x 3 LEDs
The problem i'm having is that none of the LCDs i'd like to use have such backlight LED configurations.

do the job with an input of 5V.
What am i missing or doing wrong?
