Is this meant to be portable? I'm working on a portable/UMPC myself. I believe the integrated graphics controller on most VIA boards will work without the need to add the LVDS controller. I could be wrong. Most OEM LCDs tend to include some controlling hardware as well. As I understand it though LVDS OEM LCDs are difficult to find. I'm trying to understand more about using the LVDS interface myself. I've tried reading the VIA documentation and find that it explains some, but I really just need to know exactly what it takes to interface on-board LVDS to LCD. What type of connection does it use, is it similar to/compatible with TTL/Hirose? Is there a need for extra HW, do I have to write my own driver, etc., etc. Everything I can find is either geared toward an electrical engineer with a degree or a total hardware n00b.
By the way if you want a small and fully portable solution you may consider waiting for the next gen fanless Pico-ITX due in Sept. (from what VIA's sales guy tells me). The new fanless will have the power circuitry built in so it won't need a wall-wart anymore. Good news for CarPC enthusiasts too!
BTW, if your Laptop is a Dell it may use an LVDS interface. A lot of the Inspirons do. The suitability of the screen depends on what you want to do with it. Luckily if you go here
and pick your Dell or enter the service tag. You can find an online service manual that'll give you a pretty good idea.
