How to Replace LCD backlight with LED – Transform LCD Display to LED
Warning: If you have no background on opening displays, seekout expert help on this before you unscrew your display.
HowTo: Carefully take apart the screen with clean hands making sure that the LCD, filters, and Fresnel lenses stay clean, untouched. If you happen to touch them, make sure you clean them well afterwards. You might have to use a mild cleaner, don’t use any toxic and/or heavy duty cleaners can destroy the plastic. Use a damp clean paper towel to do the initial wet wipe then use a dry but slightly damp paper towel to dry streaks immediately (using the wax on, wax off technique).
If you do it nicely, the brightness should be close to your existing LCD CCFL display, but only whiter. The only drawback you would get with a LED strip is the bright spots where LED is present and minor darker gaps. But this difference is not all that noticeable as light is diffused nicely on the screen.
