LCD Backlight Resistors?
Posted: Sat Jun 14, 2008 3:30 pmHey everyone,
Quick question, why are there resistors either side of the LED of the LCD? I shorted them out once by accident, and the LCD became considerably brighter. I checked the specs of the LCD, and the LED supply voltage is +5V, which is what it receives from the supply with no resistors, so why are the resistors there?
The reason I ask is that recently the right hand side of my LCD has mysteriously stopped working, although I can't see why the LED would affect this? I have ordered a new LCD and don't want the same to happen to the new one!
Cheers
