lcd

[ajun]

I want to assembly my own touch screen lcd. I was thinking to use some panel I pulled out from old notebook. After researching I still unsure whether I should buy a LCD controller. Anybody have good resources in regards to this mater ?

Anybody know where I can get cheap touchscreen membrane or cheap LCD ? Thanks in advance.

You're talking really technical stuff when considering controlling your own LCDs. I am sure there are line by line, pixel by pixel controllers out there... But, my suggestion would be to use an existing working laptop and taking it apart and attaching a touchscreen membrane to it that hooks up to the COM port. OR, go on Ebay and find an old panasonic or fujitsu laptop with a touch-screen. Those two manufacturers are the only two major ones I know that often put T-screens on they're laptops.

here is for putting the membrane http://www.ezscreen.com/amd.html.
the lcd and controller is from my old dell notebook.

try taing the controller from your notebook.... you wont, there is no controller. the gpu outputs DIRECTLY to the lcd row/colum dividers, which go to the lcd. I've looked around at high end contollers and the samsung ltn154u1 for about 6 months, finding controllers in the reange of about 400 bucks, with no guarantee of it working with the pannel and no bios settings for it. i gave up and got a 2001fp.

I know for a fact that a Laptop LCD has its own controller and it has a serial interface to the GPU. I believe it is an LVDS interface. You could probably find those controllers in the $100-2003 range. Or you could get a Via mini-itx board. Some of them have LVDS connectors for LCDs. For the touch screen, just look for a kit that attaches to the com port or USB port. Don?t try to make you own. Hmmmmm, maybe its time to start a car pc..............................

Thanks for the response; car pc cool idea. I am trying to make my own POS touch screen system. Do you know good store that sells the controller or mini itx board with good pricing.
