Near size-independent UV-A micro-LED performance

University of Wisconsin-Madison in the USA reports on atomic layer deposition (ALD) passivation as a means to overcome the impact of sidewall damage on micron-scale light-emitting diodes (micro-LEDs), resulting in near size-independent performance between 8μm and 100μm [Guangying Wang et al, physica status solidi (RRL) published online 23 May 2024]. The researchers comment on smaller devices: “Micro-LEDs have the potential to show higher stability under high current density while providing a higher light extraction efficiency and output power than regula...

Researchers Develop Cheaper Production Technique For Micro LEDs

SEOUL /Park Sae-jin Reporter(swatchsjp@ajunews.com) | Posted : May 25, 2021 -- Through a 16-year development project, South Korea's state research institute has discovered a way for the cheaper production of micro light-emitting diodes (microLEDs) by combining two separate manufacturing processes into a single one. The new technique using laser melding will save time and costs to eventually lower the price of microLED products. [Courtesy of ETRI] A microLED is a microscopic LED that is ideal for the production of high-performance flat-panel displays....
