AGILE ALD (Atomic Layer Deposition) thin film coating solutions expert, Picosun Group, has reported superb results in boosting micro-LED performance using ALD passivation.
Micro-LEDs are a strong challenger to existing display technologies such as LCDs (liquid crystal displays), OLEDs (organic light-emitting diodes) or conventional LEDs (light-emitting diodes). 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. Micro-LEDs are typically used for small screens such as those used in tablets, smartphones and smart watches, and the first large area displays have also been demonstrated already.
Still, the micro-LED technology has certain drawbacks that hinder its full-scale commercial breakthrough. The micro-LED screen consists of 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. At Picosun customer site, National Chiao Tung University (NCTU), Taiwan, light-emitting intensity of micro-LEDs has been enhanced by 143.7% by using ALD passivation layers deposited with PICOSUN ALD equipment.
Picosun provides the most advanced ALD thin film coating technology to enable the industrial leap into the future, with turn-key production solutions and unmatched expertise in the field. Today, PICOSUN ALD equipment is in daily manufacturing use in numerous major industries around the world. Picosun is based in Finland, with subsidiaries in Germany, North America, Singapore, Taiwan, China, and Japan, and a world-wide sales and support network.
