If anything can be said to be ubiquitous in the AV industry, it's the humble light-emitting diode (LED). From indicator lamps, to towering videowalls, to 4K televisions, to smartphones, the LED has become an essential part of our daily lives-a part we largely take for granted. We use them to illuminate our homes, as headlamps and brake lights on cars, as backlights for our laptop screens, and to keep garage doors from closing on children and pets.Until recently, LEDs worked mostly in the background. That's all changing, though-and changing rapidly-as LEDs become the preferred way to communicate information and show video on large screens. Along the way, they're coming to surpass walls of liquid crystal display (LCD) panels and stepping over high-brightness laser-phosphor projectors.Today, you could make a convincing argument that the LED is the most disruptive technology to hit the AV world ever. But it's been a long time coming.
