Read this blog post if you want to learn more about what a media panel is and why you might want one.
Success criteria were:
-Low cost: a full blown computing device and screen for between $100 and $200 all in
-Attractive: meaning my wife finds it aesthetically acceptable for the living room
-Light: no more than a few pounds
-Thin: no more than an inch thick, including frame
-Quick: can be built in a few hours or less
-Simple: requiring mainly assembly, versus construction or manufacturing
Step 1: Select the right LCD Screen
To keep things short and simple, I recommend using a 15" or 17" screen similar to the screens used in the MacBook or MacBook Pro. You can, of course, also use a screen from an old laptop you already own, but you need to make sure you can find an LCD controller board that can operate it.
We bought our screens from Laptopscreen.com, and the exact models we chose were the LG & Philips LP154WP1-TLA1 and the LG & Philips LP171WU3-TLA2. They were about $75 each brand new. Both screens were matte finish, though the next time I think we'll opt for glossy.
Don't worry so much about the numbers after the dash...they don't have a large impact on the screen. The critical numbers that determine whether an LCD Controller will support your panel and how to program it are the LP154WP1 and LP171WU3.
If you have questions, or are thinking about getting a different screen, read this blog post first.
