From computer monitors and digital display boards to smartphones and wearable technologies, many modern electronics utilize LEDs. As these devices get smaller and faster, there is more demand for LEDs that are smaller, stronger, and more energy efficient. To accommodate this trend, University of Washington (UW) scientists have built the thinnest known LED that can be used as a source of light energy in electronics. The LED is based off of flexible two-dimensional semiconductors, making it possible to stack or use in more diverse applications than current technology allows.
