Apple is supposedly planning build MicroLED screens into future Apple Watch models — in 2024 or 2025, according to a January 10 report report of Bloomberg. The move would continue Apple’s progression of using the company’s own parts in its products without having to rely on components from outside suppliers. Another report from Mark Gurman this week said that Apple is currently working on an all-in-one chip that handles Wi-Fi, Bluetooth and cellular networking. The company’s internal silicon already powers the iPhone, iPad, Mac, Apple Watch and Apple TV.

With all of these efforts, Apple’s ultimate goal is to have greater control over future products with less risk of delays and setbacks that are beyond the company’s control. With displays in particular, this shift could affect the financial prospects of vendors like Samsung Display and LG Display, which supply most of Apple’s current panels.

But as it stands today, if you’re buying the Apple Watch Series 8, Ultra or SE, you’re already getting a smartwatch with a bright and vivid display. So it’s worth examining what benefits – if any – this next-gen MicroLED technology would bring to Apple’s wearables and other devices.

Often hailed as the next big leap for display technology after OLED, MicroLED screens offer many of the same benefits. The image is generated by millions of individual light-emitting diodes that provide per-pixel dimming; each can turn off to produce perfect blacks. This results in the unrivaled contrast we’ve enjoyed in OLED TVs and smartphones for years; more recently, OLED is increasingly used in tablets, laptops and desktop monitors.

But the O in OLED stands for “organic” and actually that’s one of the downsides. The organic compound in OLED screens has a limited lifespan and still comes with at least some chance of permanent burn-in – even if that’s only a factor in high-end modern TVs. Overall brightness also fell short of the best LCD TVs that use Mini LED backlighting and local dimming to try to get a striking distance away from OLED’s excellent contrast at a higher sustained brightness.

Samsung Display and LG Display have both made significant progress with brighter OLED panels over the last couple of years – QD-OLED in the case of Samsung – but MicroLED promises even higher luminance without the issues of panel burn-in or degradation. Samsung has shown MicroLED displays that reach 4,000 nits of peak brightness, which is roughly double what the best OLED and LCD TVs are capable of right now. That’s a level of pop that would hold none environment. Like the iPhone 14 Pro and Pro Max, the Apple Watch Ultra tops out at 2,000 nits in bright outdoor environments. That’s still very bright and perfectly visible in sunny conditions, but the MicroLED could up the game even further.

If there’s one company that has so far led the way with MicroLED, it’s Samsung. The company provided an update on the situation at CES 2023. Whether you’re a display nerd or general tech enthusiast, the video below is well worth watching to understand more about MicroLED’s benefits, modularity, and how it all works. You’ll learn a lot in less than eight minutes.

In that voiceover, you will hear this key phrase: “MicroLEDs have unlimited scalability as they have no resolution, no bezel, no aspect ratio, and even no size. This means that the canvas can be freely resized in any way you want to use it – like a building block.” MicroLEDs are placed in modules that can be perfectly matched in any shape or size. In addition to being self-emissive, MicroLEDs also individually produce red, green, and blue colors without needing the same backlight or color filters as conventional monitors. Thus, the monitors can produce perfect colors and improved color brightness. As with QD-OLED, this superior color luminosity makes the entire screen appear brighter to your eyes.

Because MicroLED technology is still so new, it’s outrageously expensive for early adopters. Want to install Samsung’s The Wall in your home? You are looking at $800,000. Therefore, it is critical that these displays spread and reach more products so that costs come down – both for the manufacturer and for consumers.

Not exactly. Bloomberg reports that MicroLED screens “will be Apple’s first screens designed and developed entirely in-house,” but that doesn’t mean the company will suddenly start making tens of millions of these panels. As always, Apple will rely on manufacturing partners to produce whatever is currently in development. The company “conducts test manufacturing of the screens” at a facility in Santa Clara, Calif., according to the report, but eventually, the mass production task will go to a supplier. This is how it works with the company’s other monitors. For example, Apple comes up with a design and specification for iPhone panels and delivers them to the Samsung Display and LG Display.
