Apple considering micro LED display for 2020 Apple Watch

Posted:
in General Discussion edited July 23
Following years of development with different suppliers, Apple is reportedly close to switching Apple Watch display from OLED to micro LED, and production is expected to begin in time for a fall 2020 launch.

According to sources in the supply chain, Apple is close to signing a deal with two Taiwanese manufacturers for Apple Watch micro LED displays in 2020. If correct, the move is the culmination of several years of Apple attempting to replace the current OLED displays.

The two manufacturers are believed to be Yu Chuang, which develops micro LED processors, and Sui Bao, which assembles displays. These two companies recently collaborated on microLED products for Samsung which are also expected to be released in 2020.

Yu Chuang would not comment, but Sui Bao told Economic Daily News that its production line is ready and that it is in discussions with what is described as the US smart watch industry.

Despite that, Economic Daily News says that it will take nine months to have that line mass-produce items, and that Sui Bao is not likely to start preparations until later this year. That would see micro LED Apple Watch displays being released around the fall of 2020.

If correct, that would make it six years since Apple was first revealed to be looking into micro LED displays for Apple Watch.

Apple acquired micro LED specialist LuxVue for this back in 2014. Then in 2017, the company was reported to be doing this in order to benefit from the lower power consumption of micro LED, but it quickly appeared to abandon its discussions with Taiwanese firms due to a lack of progress.

While apparently then doing more research in the US, Apple did reach back out to Taiwanese firms with it reportedly being close to signing a deal with PlayNitride in April 2018 and then meeting with other firms in August of that year too.

    6 years because of “lack of progress”... things take time. :/ But better to wait than to have buggy technology in your devices.

    Agreed. How long did it take OLEDs to come to market? How about Color LCDs? We have a great looking Apple Watch screen right now, and as the saying goes, the enemy of good is better. I’d rather they take the time to make it great rather than rush it to market just because it’s new.

    Erbody just guessin'.  Eventually someone will be right... unless mLED turns out to be not viable like AirPower or mass production of sapphire glass screens.  My personal guess is this will be true mid 2022-2023 for the Apple Watch.  Late 2021-Early 2022 for Oppo, Xiaomi, or another of the Chinese brands.  Early 2022-2023 for Samsung.  Look at that... I am an analyst.

    Excellent post! 

    Somewhat relatedly.... if the stories about the AR glasses being delayed are true, I wonder if it's because of delays with mLED. I'm guessing the critical enabling technologies of AR Glasses are (1) SOC fabrication technology, (2) mLED, and (3?) solid state battery. 

    TSMC is doing their part -- sounds like 5nm is on target. So it's the other two that represent the big unknowns. 

    it makes sense, though, that the watch would be the proving ground for mLED and solid state battery. The year we see an Apple watch with those technologies is possibly the year before we see AR glasses.

    SOC and battery may be hindrances for the AR glasses but I don't think mLED is a hindrance.  AR glasses will require transparency to see the 'R' in AR - augmented reality.  Afaik, an mLED panel wouldn't be transparent or even translucent.  Ironically, OLED is just starting to demonstrate viable commercial applications for transparent screens.  VR though, is a field that could definitely benefit from the attributes of mLED screen tech.  AR, not so much.

    I hope this comes to pass. While I'm perfectly happy with the aluminium version of the Apple Watch, if yields mean that it's only for the SS version of the Apple Watch I don't think I'd hesitate to buy the more expensive version each year for a brighter and better display that uses less power. Hopefully this would also come with increased battery life.

    As much as I see potential with mLED, I don't think it will come until two years later. I know that Apple Watch seems to go for three years between major redesigns and with mLED will likely sporting a bigger display compared to current design, more like edge to edge.

    Samesung has their MicroLED TV. It's pretty large and can't really get smaller because they can't make the MicroLED's any smaller currently. Yet Apple can do it at the size and resolution for it's watch screen? Seeing is believing. Rumors are just that. Well see!!!!

    I would just point out that AR on the iPhone does not involve a transparent screen. AR glasses could look like sunglasses (not transparent lenses).

    Why would you point out that AR on the iPhone does not involve a transparent screen?  That has nothing to do with what we've been discussing.  You mentioned AR glasses.  mLED would have nothing to do with AR glasses.  Sunglasses would be either transparent or translucent depending on the level of opacity.  As I said in my earlier quote, mLED is neither transparent nor translucent.  It is a substrate for a screen, not something you can see through.  AR glasses will be for looking through.  

    Instead of me trying to convince you, how about we let you convince you.  Present your idea where mLED would be used in AR glasses.  Very quickly you'll realize you'll be describing a VR headset.

    Like chain fence the mLEDs  could be in grid which allows see through, but when the less are illuminated allows adding information. Since the mLEDs cells should work independently, doesn’t need the best resolution. 

    Examples. Google glasses, all projection headsets and HUDs etc. you can’t see through the pixel that has information instead you lose the visual data behind it. Like in fighter jets. But like driving past along chain fence, you can see behind it, but if you stop you can see the fence blocking the way in some parts. Eye are constantly making micro movements and the data from your left eye will be combined with your right in your brain so, I guess it is fully transparent, in a sense, even if when off you can see microscopic black lumps in the glass. 

    This is all assuming you can make a grid out of mLEDs rather than having them on a film that’s uniform with visual properties. 

    Edit:1) reminds me that we all have already two blinds spots. One per eye, that you can only notice when you have uniform paper with a different color spot. And in right place the paper seems uniform without the spot, because brains are weird. 
    2) typo mled vs mLED
    3) but still, VR headsets are capable of AR just like iPhone AR, but surely they aren’t AR headsets, as you said.

    And even with transparent screen you still have the grey problem.
    How do you mask part of the view without adding some distortion to the view beyond?
    It's going to be like smudged glasses for a few generations.

    1.  I can't argue "what if" fiction.  We'd end up down a rabbit hole of "what if mLED had this property or that property like phase shifting molecules or color shifting individual cells.  We can make anything work if we stray far enough away from reality.  mLED can't be constructed the way you've proposed so trying to argue the +/- seems unproductive.  
    2.  Examples:  Every example you listed has a substrate that is either transparent or translucent allowing the viewer to see through it.  Arguing that you can't see through the pixels of the image is irrelevant since the substrate (what the image is projected on) is what the discussion is about... not the image.  
    3.  VR headsets that have a camera are capable of Mixed Reality (MR) not AR. Pedantic, I know.  MR is what the iPhone is doing as well, but that's also being pedantic and derailing the topic of the mLED substrate.  Point being.  Apple's AR glasses would not be hindered by anything going on with mLED, which was supposition of blastdoor.  AR glasses don't need mLED.

    Would really hate for this tech to be shortened “mLED” since the “m” prefix is already reserved for “milli”. µLED would be a much better, and correct, abbreviation.

    Good luck with that.  I fear that you're just going to have to live with hating it.  It's probably going to stick around, grow in use, and become the commonly accepted abbreviation.  You can, however, take solace in the fact that you know the difference.

    Keep in mind that we still live in a world where even amongst tech forums we use the same notation to denote decimal and binary values so I think you're SoL in getting the legacy micro symbol adopted for micro-LED. As far as I know there isn't even an long-hold option for for lowercase Mu on an iOS keyboard, which I'd think would have to be a minimum for general adoption. I think you're best bet is to just refer to it as micro-LED.

    Why would you point out that AR on the iPhone does not involve a transparent screen?  That has nothing to do with what we've been discussing.  You mentioned AR glasses.  mLED would have nothing to do with AR glasses.  Sunglasses would be either transparent or translucent depending on the level of opacity.  As I said in my earlier quote, mLED is neither transparent nor translucent.  It is a substrate for a screen, not something you can see through.  AR glasses will be for looking through.  

    Instead of me trying to convince you, how about we let you convince you.  Present your idea where mLED would be used in AR glasses.  Very quickly you'll realize you'll be describing a VR headset.


    Like chain fence the mLEDs  could be in grid which allows see through, but when the less are illuminated allows adding information. Since the mLEDs cells should work independently, doesn’t need the best resolution. 

    Examples. Google glasses, all projection headsets and HUDs etc. you can’t see through the pixel that has information instead you lose the visual data behind it. Like in fighter jets. But like driving past along chain fence, you can see behind it, but if you stop you can see the fence blocking the way in some parts. Eye are constantly making micro movements and the data from your left eye will be combined with your right in your brain so, I guess it is fully transparent, in a sense, even if when off you can see microscopic black lumps in the glass. 

    This is all assuming you can make a grid out of mLEDs rather than having them on a film that’s uniform with visual properties. 

    Edit:1) reminds me that we all have already two blinds spots. One per eye, that you can only notice when you have uniform paper with a different color spot. And in right place the paper seems uniform without the spot, because brains are weird. 
    2) typo mled vs mLED
    3) but still, VR headsets are capable of AR just like iPhone AR, but surely they aren’t AR headsets, as you said.
    1.  I can't argue "what if" fiction.  We'd end up down a rabbit hole of "what if mLED had this property or that property like phase shifting molecules or color shifting individual cells.  We can make anything work if we stray far enough away from reality.  mLED can't be constructed the way you've proposed so trying to argue the +/- seems unproductive.  
    2.  Examples:  Every example you listed has a substrate that is either transparent or translucent allowing the viewer to see through it.  Arguing that you can't see through the pixels of the image is irrelevant since the substrate (what the image is projected on) is what the discussion is about... not the image.  
    3.  VR headsets that have a camera are capable of Mixed Reality (MR) not AR. Pedantic, I know.  MR is what the iPhone is doing as well, but that's also being pedantic and derailing the topic of the mLED substrate.  Point being.  Apple's AR glasses would not be hindered by anything going on with mLED, which was supposition of blastdoor.  AR glasses don't need mLED.
    1. You asked an idea and I gave you one. At no point did you mention it needs to be currently in use. I don’t see the grid as sci-fi. A led needs +\- wires to work and mLED is just scaled down. I guess you’re the authority here on what is possible and what is not. 
    Phase shifting molecules?... You’re just mushing up terms in order to seem smart. Color shifting individual cells? Like LCDs? 

    2. If you want information on the screen the image is of importance. I guess you missed the whole idea of the grid. You can’t see through the mLED pixels, but loosely enough you can see between them. So it just blocks some of the photons in the way. Of course they’d be on a transparent film or in a glass pane, not on thin air..

    3. Sure agreed, they don’t need mLED. But you asked an idea where they’d be used in AR glasses.
