Need help to get TFT screen connected to Pi

Thu Dec 26, 2013 8:16 pm

EDIT : Don't mind this topic anymore ;)

Hey guys !

So long story short, I managed to get a TFT screen from a broken picture-viewer, and I need your help to make it usable :D
This is the screen :

Datasheet (which I am not able to read, I'm a noob see? :roll: ) :

And a picture of how mine exactly looks :

So as you can see I have three cables more on my module than on the one in the picture (on the top, green/red/yellow wires) and have no clue why.
I understood that the "green thing" is for the voltage and probably to transform the incoming voltage into a better one ?
Anyway, the reasons I made this topic are two : What input should I give him (Voltage and intensity ) and is there anyway to basically get some composite females instead of strange wires to be able to connect to devices? (Yeah, I'm that much of a noob)

Thanks guys !

The data sheet has a lot of the information you require, but if you're finding it hard to understand, then I think you might have difficulty with anything I were to write in explanation.

You don't say what you want to connect it to, but assuming you want it to show the output of the Pi, there's going to be a long, long road ahead of you.
The Pi has a connector for a display, but it isn't configured in the same way as your screen, so you'll have to build some rather complicated interface electronics.
To do that, you'll need to understand both the screen and the Pi's interfaces, as well as the chips in your electronics
Not for the faint-hearted, and not for a beginner :(

I informed myself and got to the same conslusion as you so yeah, I'll just temporary put it in a wardrobe and wait for it to become a possible challenge !

Have a nice day :)

It should be possible to use a TFP401A - I have actually used this IC to connect a AT070TN9 display to the Raspberry Pi.
Although, as Burngate already mentioned: That is not so easy, you should be at least able to build a PCB and solder a TQFP 100.
