Pocket tv, psone lcd power

Guest · Post by **Guest** » Fri Oct 08, 2004 4:47 pm

Which would use up the batteries quicker, a pocket tv, or a psone lcd?
I kind of want to use a psone screen but I'm thinking such a big screen would run down the batteries quicker.

Because of its size, PSOne screens suck up battery power more and won't last as long. If you're good at this, however, you can change the backlight with white LEDs and make it run longer than a pocket tv.

Yeah I think the PSone screen only needs about 200 milliamps for the screen and then 600 milliamps for the backlighting. I found this out when I used 4 LEDs for the backlight and each LED needed 3.6v @ 100milliamps. Since I used four in parellel it came out to 400 milliamps needed and when I checked the amperage of the whole thing it said 600 milliamps.
600-400=200! I just checked it came to 200 milliamps so the PSone screen actually doesn't use that much power. I wonder if only 2 LEDs would be eonough for the backlight................If so the PSone screen would only use 4oo milliamps! I'll have to try that out.........

So ,how many milliamps would an average pocket tv modded with leds use?

Well from what Ben has documented he's said his tvs used 500mA, then with the LED mod they went down to 250mA.

Hmm, I guess I will be using a pocket tv then.

actually, it may be worth it to have a bigger screen even if it does draw more power. what kind of batteries are you going to use?

I'm not sure what kind of batteries I should use. I want my portable to last as long as possible, though. (It's gonna be a portable NES made from a superjoy3 BTW.)

If you don't mind an extra 40-60 lbs., you could always use a 750 Ah sealed lead-acid car battery

Just put the battery in a backback and carry it around
