yes, a 10.2" widescreen 16:9 lcd kit does exist.
I will be releasing mine to the public in the next 2-3 days.
Right now it is a bare (open frame) setup. I am in the process of designing and milling an aluminum bezel.
Touch screeen is an option.
I have attached a teaser pic.
The panel is an AU, which is a high quality panel.
Brightness will be close to 800 nits (780 without touch) and will only loose about 12% with touch.
contrast is 500:1
vga and video inputs will be offered.
Pricing is not set firmly, yet. But, expct this kit to go for 430ish with touch, vga and video.
