So i'm trying to use an laptop lcd screen on my duemilanove, but i have a problem don't have the pin out and its also my first time with screens, the screen has two buses, one with rainbow colors and the other only with r/b wires wich are suposed to be Vin Vout
Here are the images
The screen is QUANTA DISPLAY LK11 QD16TL02, don't know if it would help, i have also a photo of the display
Hoi,
it all depends on the built-in controller chips AND the availability of a depending LIB for that - otherwiese you have to write your own parts for the lib.
"What shows the display or what it makes not ?"
p.s.- try googling the specific type of display for connection info from a DIY post somewhere.

Laptops and PCs have a graphics card for a reason. An Arduino is not a graphics card. It cannot generate the signalling required for such displays and even if it could it wouldn't be fast enough. These displays are not like the little 'hobby' friendly displays (e.g. Nokia 6100), they have no memory, no frame buffer, no graphics controller. You have to send them the raw R, G, B, Control, PCLK signals (the control signals are usually digitally encoded onto the RGB lines), and for a display that sort of size the pixel clock is usually in the region of 50-100 MHz. Anything less than that and they won't do anything.
This is not even a display. It is an lcd panel. To be a display, you need driving circuit for the liquid crystal cells and back lights. I bet those circuits are on the laptop. This panel is useless to anything o5her than that particular laptop model line. If you want a large display for youe project, get an android tablet and prepare for a lot of programming. Try tv shield or game shield instead. They may save you time from programming.

Not actually true, they tend to use a universal interface. It is possible to get driver boards for them (I have one) that you can then plug a VGA cable in to. But they cost something like £80 or more. Even then you would still have to use a large number of Arduino pins to generate a VGA signal which wouldn't be an easy task.
I was not aware of the existence of this universal interface. You can get a game shield for vga connection. It has a controller on the shield.
