Using unregulated 12v okay on LED backlight screens?

Just as the title says... Is it okay to tap into the car's unregulated 12v (cigarette lighter) to power the screen if the screen is using a LED backlight? All the threads i've read regarding powering the screen say use regulated 12v from a power supply to prevent blowing up the CCFL inverter. So is a LED backlight okay?

depends on the internal regulation and if the documents say it is OK.....

What does the doc say?

The only thing regarding power that the manual covers is this: "Power Source: DC12-24V", and "Power Consumption: 600mA(max)"

The screen in question is the Phylon 8" open frame from Logic Supply.

That is your answer then 12 - 24 is a large range.

Some come with a cigarette lighter adapter that has a regulator inline with the power connector. For the EBY701 I just cut the cigarette lighter plug off and wired it to the harness that I was using. The regulator kept it in a decent range but nothing like a computer psu. Sounds like you are fine though.

Make sure your lighter is on a switched circuit...
