Ok,I don't know if this really classifies as external hardware but i'd like an experienced person to give me his opinion.So I took this screen(i don't know if it s led ,it s similar to the way calculators show numbers or letters) from a bluesky dv900 dvd and I want to show my own numbers and letters on it.Maybe it can be programmed but I don't know how to connect it,or maybe there is some other way.

So it looks like it has 11 pins going out of it,another 2 that go out of the on/off button and i'd guess the black wire is a ground,since i found it on a metal piece inside the dvd.

I don't know if there's going to be a easy way to do that. It's a gas plasma display, it needs supply voltage and a small voltage to heat a filament which will be supplied by the DVD's PSU, and a multiplexed data drive from a control microprocessor. If there's any way to find out the control matrix, maybe you could do it with a Raspberry Pi or something, but I'm not sure how readily you could get the information about the operation of the DVD's display circuitry.

Plasma.....
And I thought I can power it up with a 5 volt battery :))
This thing is a dinosaur,I don't think it is possible to find a control matrix for it.
I thought I might be able to use an soldering iron to an usb head or something,but now I realise it ain't gonna be that easy.
Thanks for the response!
