Organic light-emitting transistor

Organic light-emitting transistors are like switches. When you press a switch, it turns something on and off. Organic light-emitting transistors do the same thing, but they turn light on and off. They can be used to make very thin and small screens, like the ones we have on phones, computers, and TVs. They are also used to make lights and signs that are powered by electricity.
