can u re-wire laptop LCD for desktop use ?

[divxdude]

someone has a 12" gateway LCD i'd love to re-wire for destop but i dont
know how to go about it.

possible? is there any guides?

are they all similar or all different? (pinouts)

 

[PottedMeat]

generally, no. i think the graphics chip directly controls the screen with a custom interface, so there is no VGA->LCD pinout possible.

I think the pinout of the LCD is fairly standard, but you would still need a controller card to convert the VGA signals to the LCD drive signals. On laptops this is embedded in the motherboard - it's not a standalone card, so you couldn't remove it & put it in another system. The controllers are available (try www.earthlcd.com), but it would probably be easier and cheaper to buy a cheap LCD monitor - it looks like their controllers start at around $200 for a PCI card.

Along the same lines I have a question:


Why are laptop lcd's so much better than desktop ones. The laptop I'm typing to you from now has a 1920x1200 res and is 17inch widescreen. I don't know of a single desktop monitor this size that has these resolutions.

 

[divxdude]

bummer
just can't have any fun on a poor mans budget anymore..

This gets asked around here quite frequently. The short and frank answer is "no".

Yeah, I've seen this asked before. Basically each manufacturer uses proprietary signaling, and they really have no reason to release the spec for it. So basically, no.

Yeah, I don't think there are any, really. However, in desktop LCDs, what you lose in resolution, you gain back much more in accuracy of color, brightness, contrast, and response time. To say that laptop LCDs are "better" is quite a bit of a false statement.

i dunno about that. my laptop LCD is incredible. its a 15" UXGA and its color and sharpness are unparalleled in any desktop LCD ive ever seen. it was expensive and worth it.

 

[cirthix]

it uses either lvds or ttl signaling. you need a controller board and the bios of that controller board flashed to have the right parameters of the lcd its controlling. its a pita, but its not impossible as most think. expensive too might as well get a 17" off newegg

Essentially you need to make your own graphics card that has the hardware and software to feed the panel its native signal type and timing, and you need power conversion and inverter to get the backlight going.

It can be done, but not without a huge development effort that nobody is going to put into it - not for one unit. Not even those people who _know_ how to do it.

Want a 1024x768 14" panel? *hint hint*

It's easier to do it for older black and white LCD's that has been in a halt in production of number of years ago, however they were never laptop displays to begin with.

For the guy who mentioned that no one would attempt to rewire or constuct graphics cards for themselves:

"It can be done, but not without a huge development effort that nobody is going to put into it - not for one unit. Not even those people who _know_ how to do it. "

LCD developers are willing to do this, in fact their research departments go through much more than this.

 

[Peter]

Of course. But they're not doing it for a single unit.
