Picosun Group, supplier of AGILE ALD (Atomic Layer Deposition) thin film coating solutions, announced that its ALD technology was used to successfully boost Micro LED performance.

Offering compact size, low power consumption, superior brightness and energy efficiency, greater contrast and color saturation, ultra-high resolution, flexibility and good reliability, Micro LEDs are currently actively studied and developed at the leading electronics manufacturers and R&D institutes around the world.

However, Micro LED technology has certain drawbacks that hinder its full-scale commercial breakthrough. The Micro LED screen consists or minuscule pixels producing green, blue and red light. Some steps in the manufacturing process of these pixels easily cause damage to their delicate nanometer-scale structures, which leads to loss of light intensity. ALD has now been proven to effectively fix these damages, not only restoring the light intensity but actually boosting it to superior levels.

National Chiao Tung University (NCTU) in Taiwan, by using ALD passivation layers deposited with PICOSUN™ ALD equipment, has enhanced light-emitting intensity of micro-LEDs by 143.7% .

“We are happy to report these great results achieved in Micro LED efficiency enhancement using ALD technology. PICOSUN™ ALD equipment have been an integral part of our facilities for a long time, and we are always impressed by their performance and the superior ALD film quality obtained with them. Picosun’s customer support is also impeccable, which is very much appreciated considering we collaborate extensively with industries. Whenever we need something regarding the equipment or process consultancy, Picosun staff is always up to date and ready to provide thorough answers,” stated Professor Hao-Chung Kuo from NCTU.

“NCTU is our prestigious customer and key partner for years already. We are glad that our ALD solutions have enabled this impressive performance boost to their Micro-LEDs. Micro LED technology has immense potential to disrupt the solid state lighting market and our Asian customers, both in industries and R&D, will surely lead the forefront of this development,” continues Mr. Edwin Wu, CEO of Picosun Asia.
