Will this work. I have the one 7" DVD screen with barely any guts. If I hooked up a board from another screen (that outputs composite) to the correct pins, could I possibly get this screen running?
Also, the LCD is just an LCD right? There's no special LCD for a digital signal and an analog signal? It's the boards that do the signal accepting and rejecting, right?

The LCDs need to have the same native resolution and the same interface (i.e. LVDS) to be able to interchange OEM controllers. If they are that simular, you'll just need to match up wires.
That's why LCD controllers you see for sale separately are so expensive, they have to be adaptable to a wide variety of screens, which makes them more complex.

Don't bother with retromaster, he has no clue of to what he's talking about.
Actually, I happen to have that exact same screen sitting right next to me! Unfortunately, I broke it.

That thread might give you some nice information depending on the screens' part numbers your mixing up.

@ Skyone: Seen that thread, didn't help much. What were you using YOUR screen for?
@ Tom: I'm intrigued. I have a 7" screen and a 5" screen's board. Will this result in a stretch, a letterbox, or complete incompatability?
All this stuff is assuming I don't get it sold on ebay on monday. I hope to God I do, but just incase, y'no.

If both are the same resolution in X and Y (ie both 320x240), have the same interface and the same ratio (i.e. 4:3), then the screens are the same except the size of the of the pixels, and will be full screen using either controller on either screens. If the 7" is the same res(and the other things mentioned) , but the 7" is 16:9 and the 5" is 4:3, having the 5" screen's controller on the 7" would result in the picture being 'stretched'.Kurt_ wrote:@ Tom: I'm intrigued.

Additionally, there is one more consideration in LCD compatability that I haven't mentioned, and that is dot-clock (sometimes a dedicated line, or H and V combined). You don't have to worry about this in most cases, as the dot-clock should be the same if the screens are the same res and refresh rate. The problem is when the refresh rates are different, so a controller from a PAL screen may not work on a NTSC screen, but will work in some cases, dependng on how the controller handles the dot-clock.
