    Nothing right now. I have been in contact with all of my sources for touch screens, but they are on Holiday until the 8th.

    I did locate a 4 wire resistive panel that is USB, but no luck on a capacitive version yet.

    ok, thanks, hopefully a capacitive version can be located soon, I'm getting excited!

    I don't know if this will help in any way but a website did tear downs on the iPad and iPad 2. They may be built into the logic board but they did mention the controllers used. They both use these two controllers:

    -Broadcom BCM5973KFBGH Microcontroller used for touchscreen

    -Broadcom BCM5974 CKFBGH capacitative touchscreen controller

    I too am interested in using the iPad display and touch screen for my Car PC build . I don't know if the above will help at all but I thought I'd just through it out there.

    Is there any news or reviews on the kits tft_lcd_org posted? I tried to inquire via website and they didn't respond. Also i read in their conditions under warranty it basically says everything comes as is no gaurantees. Lol so by all accounts this is not a reputable path to take, but i desperately want something besides a lilliput lol, and i've been emailing chinese dealers for weeks now trying to get a solid setup for a 10 in screen with respectable specs.
    so once again review, opinions?

    All new displays I sell come with at least 30 days warranty. Hardly "not reputable".

    I have responded to you, however you are asking for more than I can deliver.
    You want to use an LCD panel that has a connector not found elsewhere (might be proprietary), which means for now I cannot make a cable for it to work on an LCD controller.

    I think what happened is you saw an LCD panel you liked and want to turn it into a display for a car, and frankly that is the wrong way to go.
    Instead, try looking at options already available. Not saying that in some cases an off the self LCD panel can be made into a useable display, but in your case that won't happen. Not with that LCD anyway.

    The 10.1" Pixel Qi display w/capacitive touch makes a great 10.1" solution that works well in the automotive environment, and should suit your needs.

    Hello, I just found this thread, and I was wondering if anyone knew about the ipad 3 display? It probably has the highest pixel density in a commercially released product, and I would like to give it a dvi interface. Anyone have any idea how much it would cost/what controller would be needed? Is this:http://www.truesupplier.com/oem-appl...-pr-29884.html the right panel?

    Found the model: ltn097ql01-a02

    Has anybody thought about taking a magictrackpad apart to help with touch portion?

    My understaing is it has a Broadcom BCM5974 touch screen controller chip.

    Actually I was very impressed with an App called Splashtop doing remote desktop to my car PC from my iPad. Very responsive, and the touch screen worked perfectly.

    Of course you need to wake up the pad each time you turn on the car, but I've heard that hacks are available.

    Unfortunately I don't have space for an iPad, and don't want a frankenmount bolted on to my dash.

    Hacking the iPad touch panel would be nice, but obtaining datasheet, or any information for that sake on the two chips responsible for the touchscreen:

    CD3240A from Texas Instruments
    BCM5974 from Broadcom

    I guess they're custom manufactured for Apple, so we're **** outtaluck on those.
