MicroLED Apple Watch Ultra Project Potentially Loses Another Supplier

The rumored microLED Apple Watch Ultra project may have lost another key supplier, according to Display Supply Chain Consultants CEO Ross Young.

In a filing with the U.S. Securities and Exchange Commission on Monday, manufacturing equipment company Kulicke & Soffa said that one of its "strategic customers" has canceled a project related to the "advanced display" market:

Previously referred to as Project W, the Company has been engaged with one of its strategic customers (the "Customer") to support the Customer with the development and future mass production of certain technologies relating to advanced display (the "Project"). In connection with the Customer's strategic review of its business, the Customer has informed the Company that it has cancelled the Project.

In a social media post on Monday, Young suggested that "Project W" was potentially related to the microLED Apple Watch. The company said it expects to incur charges of up to $130 million as a result of ceasing operations related to the project.

Kulicke & Soffa's website advertises a "next generation LED die transfer" system for microLED and miniLED displays with "an unprecedented transfer rate at high precision."

Earlier this month, Apple supplier AMS-Osram similarly announced it would "re-assess its microLED strategy" after a "cornerstone project" was "unexpectedly cancelled." Young believes that project also related to the microLED Apple Watch, so there are now at least two major suppliers that have indicated they are no longer involved.

Both Display Supply Chain Consultants and Apple analyst Ming-Chi Kuo believe that Apple has outright canceled the microLED Apple Watch project for now, but other sources like Bloomberg's Mark Gurman and DigiTimes have cast doubt and believe that Apple has or is actively seeking alternative suppliers for the project.

In any case, a microLED Apple Watch Ultra appears to remain several years away at a minimum.

MicroLED has been a few years out for a few years and seemingly will remain a few years out for the next few years…
Whatever, my Ultra2 display is awesome and so is battery life…

I thought this had been added to the ever increasing pile of cancelled projects?

ELI5: Why is a micro LED watch a big deal over the current display? Battery life and/or brightness which are already really good?
Higher contrast ratio and brightness. 10-20-30x brighter.

Sounds great, except microLED's biggest challenge is power and heat especially in the PPI density of a Watch. This is why you see microLED TVs doing fine. You just need more power. But nobody is successfully miniaturizing it down to a wearable.

In an industry that's just spent a decade and billions of dollars attempting and mostly succeeding to perfect OLED, it's hard to imagine there is widespread motivation to suddenly replace it with something that lasts potentially orders of magnitude longer before needing to be replaced. Relatively niche applications like the watch notwithstanding, I do not expect to see MLED making waves in the consumer display market any time soon.
Longevity isn’t an issue, because the devices are obsoleted by software first.

I wonder if OLED is getting better than they ever thought it would, and there's less pressure/incentive to push microLED. I mean, I for one never expected them to hit 3000 nits with OLED so soon.
It’s just that it’s not “economically viable” to produce microLED at this point in time yet.

Recent reports a single display for an ultra would cost APPLE around $150. On a BOM that’s a huge step up from what the current OLED costs.

microLED requires some of the most advanced precision manufacturing to date. The pixels are so small I don’t think they can use a printing method yet, I can only imagine that some sort of vapor process is involved? It’s really a flabbergasting manufacturing feat to attempt the more I look into the technology.
