After we get something decent, then we'll be wishing for OLED...

You can get a 10.1" Capacitive touch panel, and I believe I saw a 10.1" 2560x1600 panel out there somewhere. It's basically what's in the Nexus 10.

Really?

Which one do you have?

NJY does not sell USB Capacitive panels unless you want to have a custom panel made. And, they want 3000pc minimum order for that.

Their capacitive panels are I2C interface. Without the HID descriptors from them (they don't have them) you can't even get those to work with an I2C enabled device.

But does win7/8 recognize them as a touch screen or as a mouse?

I was going to use Win8 on my CarPC until I found that my egalax driver is only seen as a mouse and not a touch screen so the swiping doesn't work.

I have a screen I bought that uses a 4 wire multi touch USB egalax driven touch.

Would you possibly have a replacement touch controller that would use a driver that is compatible with win8 gestures?

Can you send me more information on that display? or maybe some pictures of the touch connector, controller, etc?

Thanks

Mimo has a 10" capacitive.

I have a 669 capacitive from tft_lcd and its great. X and Y axis are inverted and you have to revert them every time it starts up... Kinda a pita

Thanks again, the screen is working in the correct orientation, very accurate and crystal clear.

You are welcome. Glad you like the display.

Any idea as to what needs enabled in the Linux kernel config for the touch controller?

**EDIT: Ok I'm getting much closer. You may want to let people know that the digitizer you use is a Atmel maxTouch device. To enable in linux kernel, enable: CONFIG_TOUCHSCREEN_ATMEL_MXT=y

I will be testing this and will return with my results. Looks to be promising, may have to update the kernel driver code to the latest Atmel has made avail but may not need to.
