Are there any considerations for the polarity of wires on a CCFL tube?

I am converting a monitor from 120vAC to 12vDC using a generic inverter (AVT4029; also have AVT4168 not pictured) and LCD driver board. The CCFL tubes are encased in the assembled display (Samsung LTM230HT01) and I would like to avoid further disassembly for risk of damage. The CCFL wiring harness is similar to the standard small CCFL connector found in laptops, except the connector has 4 pins on each harness (connector: YEON-HO 35001HS-04L), 2x harnesses on the display so 4 lamps. Pairs are red/white and blue/gray. I cut the connector in half so it fits into the generic inverter. The wires are all of the same gauge.

Edited to add: the spec sheet for the panel is here http://www.spectrah.com/product/lcd_panel/samsung_lcd_panel/Samsung-LTM230HT01.pdf


CCFL's like NEON tubes, enjoy AC current with light emanation in each polarity. Each tube is rated in mA and power rating. ( keep it on dim to extend life of CCFL and your eyes)
