Silicon is everywhere. It’s in the device you’re using to read this site, it’s in your computer, your phone, your camera, your car, your thermostat, your microwave, your artificial heart, the nearest hospital/police station/fire station/library/Starbucks, in the sky, deep in the ocean and up in space.
It’s pretty hard to beat silicon at what it does, but some folks at the University of Florida have done a study that says carbon nanotubes may be a better substitute in displays. And if there’s anything to that shoves research into overdrive, it’s the end goal of human entertainment. 247 million TVs were sold in 2010, and competition among manufacturers is fierce. Bring on the innovation! From… I dunno, some random-ass site:
Most OLED displays use a thin film transistor made out of silicon as their electrical foundation. The transistor powers a sandwich of organic materials layered between two metal plates, which pushes an electrical current through the stack of materials.
In a series of experiments McCarthy and colleagues showed that their carbon nanotube based transistors operated at lower voltages than silicone based transistors. That means they consume less power, without compromising brightness or colour intensity.
