MicroLEDs moving from lab to fab

An article written by Laura Peters for SEMI Engineering, based on an interview by Eric Virey, Ph.D., Senior Industry Analyst at Yole Développement (Yole) – Bringing the cost down and yield up on microLED is proving to be formidable, but display companies and LED suppliers are working together toward production-worthy solutions.

Every disruptive technology has its “aha” moment — the time when everyone from engineers to investors realizes that, yes, this technology is the real deal and it won’t be scrapped on the R&D floor.

For many, it was Samsung’s recent announcement of a 110-inch microLED TV that irrevocably put microLEDs on the map. The TV’s price is $155,000, but as with most consumer electronics that go mainstream, economies of scale will sharply reduce that amount.

“It signaled that microLED TVs are coming, but lots of engineering advances and disruptive technologies are needed first to reduce cost by 20X to 30X for mainstream adoption,” said Eric Virey, Ph.D., senior industry analyst at Yole Développement. Some of the first commercialized microLED displays will be for near-eye augmented reality/virtual reality or mixed reality applications for head-up displays or glasses.

MicroLEDs have outstanding performance attributes. The offer higher pixel density, lower power consumption, faster (nanosecond) response time, and wider viewing angle than LED-backlit liquid crystal displays (LCDs) or organic LED (OLED) displays. Importantly, they offer an order-of-magnitude higher luminance than OLED displays or LCD in direct sunlight conditions, which is crucial for handheld devices, as well as a key enabler for near-eye displays.
