Lesics, a YouTuber, creates beautifully illustrated videos about some of the most recent developments and technologies. You may recall this episode in which he explained how railway power lines work or this clip in which he examined the engineering behind the Burj Khalifa.
He is now back with another issue on the physics of LED technologies. LED technology is still being developed by scientists today. While OLED technology has surpassed simple LED technology, new advancements may reclaim LED as the king.
But exactly what are LED displays? They are made up of a flat panel display with an array of light-emitting diodes serving as pixels for a video display. Because they are so bright, they can be used outside for store signs and billboards where they will be visible in the sun.
We’ve also seen them in destination signs on public transportation vehicles and variable-message signs on highways. They are also an attractive alternative to traditional projection screens.
With their use in so many different industries, one might wonder how OLEDs are outperforming them. What is the difference between the two technologies, and how can LEDs catch up? Finally, what is the future of LEDs?
