BACK LIGHT
CCFL : driven from backlight connector by ac450v/80KHZ, 5v DC can be converted to AC 450V/80K HZ by a CCFL- INVERTEREL : driven from A,K directly ( on right or left side of PCB) by AC 110V/400HZ, 5v DC can be convertd to AC 110V/400 HZ by a EL-INNERTERLED : 1. driven from interface pin (15, 16 as in character LCM) by 4.2v DC. If providing 5v DC, please put a limited resistor on RL ( 3~6 ohm) 2. driven from A, K directly (on right side or left side of pcb) by 4.2v 3. driven from Logic Vdd and Vss ( interface pin 1 and pin 2). Must put a limited resister on RL.
