Chocochan is working on a DIY Wacom Cintiq project using the LCD panel that is used in the Microsoft Surface Pro tablet:
I wanted something small and portable that wouldn’t take up much space and be light to hold. I don’t have a large desk and I don’t traditionally draw on much that is bigger than A4 (A5 is a comfortable size for me, so anything bigger is a bonus), so all that extra active area Wacom promote on their “Pro” tablets is wasted on me. One thing that Wacom can’t seem to do right is make a lightweight, compact Cintiq. I know that it’s usually the digitiser board inside that causes their tablets to be physically bigger than they actually are, but with screen style tablets; since the digitiser is installed within the LCD panel’s housing, they have no excuse to not make smaller PCBs for the buttons/wheels/whatever.
