Most of us have used or seen LED and LCD displays in the past. Most phones or tablets take advantage of these technologies. You can use these in more than just handheld devices though. Take the YourVideoBadge Video Name Badge. It is an enhanced badge with a 4.1 inch touch AMOLED display (by Samsung).
The device features 4 GB of memory, WiFi, Bluetooth, and a battery that can last you up to 12 hours between battery charges. The badge is for businesses that are looking for a more effective way to advertise their products. It will be made available in 2013.[via]
