For years I've wished I could recycle laptop displays instead of just throwing them away. It just seemed so unnecessarily wasteful. Now I can reuse them thanks to some enterprising people in China and eBay.
Using this driver card and cables, I was able to build a Raspberry Pi development bench, or portable display, or whatever you want to call it. I can use this 15" touchscreen with any computer video source. It has VGA, DVI, HDMI inputs, as well as audio in and out (which I have not tried).
For 25 bucks and some 3D printing time, this is pretty cool, in my opinion.
Interestingly enough, I just found a project over on Hackaday related to this same idea.
Recycled Laptop Displays is, as far as I'm concerned, something that works!
