The United States invented a new method to improve the efficacy of green LED light

[High-tech LED News] Recently, researchers at Rensselaer Polytechnic Institute in the United States found that nano-etching at the junction of the sapphire substrate and the gallium nitride layer of the LED causes the LED to produce green light, which greatly improves light extraction. Internal efficiency and amount of luminescence.

Computer monitors and TV sets display colors through red, blue and green. Red and blue LEDs have achieved high-quality and low-cost production targets, so green LED production technology is a breakthrough that the industry has been seeking.

The technology is based on the cheapest sapphire substrate and will improve the light output of red and blue LEDs, which will drive LEDs toward high performance and low cost.
