"OLED" means organic light-emitting diode, named for the advanced material used in the screen. This carbon-based substance glows at the introduction of electricity, and the light passes through a combination of filters and a color refiner to reproduce spectacular high-definition images. This design also reduces the thickness and the weight of an OLED TV. OLED displays can now be manufactured at larger screen sizes, so it has become a viable home theater display technology for the first time, alongside LCD and Plasma TVs.
Although "LED" stands for "light-emitting diode" in both cases, the design of each is actually quite different. LED TVs simply use an array of LEDs as the backlight for an otherwise traditional LCD (liquid crystal display) TV, shining through a screen of LCD pixels. But with OLED TVs, the organic layer creates its own light source for each pixel. As a result, OLED's improvement over LED's color, clarity and black level is dramatic.
Fortunately, the LG OLED TV is both a 3D display and a Smart TV. With lightweight, battery-free glasses, LG Cinema 3D offers theatrical-quality 3D as well as 2D-to-3D conversion, looking even better thanks OLED's amazing picture. LG's exclusive 3D World app arrives ready to deliver both free and premium 3D content immediately. The LG OLED TV also taps the internet to provide movies, apps, games and more, with a customizable Home Dashboard interface and a sophisticated Magic Remote.
OLED is a new panel technology, which displays video in breathtaking new ways. ULTRA High Definition (UHD), also known as "4K," is a new resolution standard for video that will essentially quadruple current HD quality. "OLED" and "UHD"/"4K" represent very different things, so there's no fair comparison between them.

Absolutely. Despite the leap forward in picture quality, this is still a "high definition" device, perfectly suited to the current generation of source components. It will display Blu-rays in glorious Full HD 1080p, and they will look better thanks to OLED's superior image rendering technology. Your Streaming devices will work as well, along with any other source component with an HDMI output. (The LG OLED TV offers four HDMI inputs.) But remember that the LG OLED TV is also a Smart TV, capable of wireless internet streaming directly to the television even without an external box.
