However, I've only actually seen it happen when intentionally rotating the screen beyond anything I would normally do, to see the blue effect. Not really a factor in day-to-day use for me, or, I suspect, most people.
The vague warning on burn-in sounds a little bit alarming. Couple years back, I had a MacBook Pro that had that well-known "image persistence" defect and that drove me nuts. I hated and quickly sold that machine.
Having said that I have not seen anything like that yet on my talking poo phone.
(I should also probably add that this is by far the best screen I have ever seen in my life... to the point that I am a little less satisfied with my 5K desktop monitor and iPad Pro screen than I was last week :-P )
Rather than just whining about it, I’ve simply done the only thing I can do and not bought the latest iPhone. An infinitesimal drop in a near-trillion dollar ocean.
I suppose for Pokemon Go, but who still plays that anyway.
Having said that, the screens that I use the most are all OLEDs and they are amazing displays, the best displays I ever had.
If you are careful there is no such a problem. It is going to be a big problem if you use the screen outdoors because you will have to ramp up the display intensity. This is the reason Apple recommends using the ambient light sensor, because most people are indoors most of the time, with orders of magnitude less light intensity for the screen to compete.
And being outdoors there is a significant difference living in Madrid,Spain or Saudi Arabia with more than 300 extremely sunny days per year, or living in Frankfurt or London, when most of the time is cloudy.
We should have to wait to other screen technologies for "having it all". Looks like Samsung real electroluminescent QLED will be as good as OLED without the problems, but there is a ton of work that needs to be done. I believe it is remarkable how far displays have gone.
I had a hight definition 19'' CRT that costed 20.000 euros back at the time, that weighted more than 30 kilos. When I see people dissatisfied with current tech...
And sure the 19" CRT was 20k not 2k?
off the top of my head, i would say that the burn in is caused by degradation of one of the color elements in the leds. the blue elements were a problem for a long time -- they would degrade very quickly. i would guess that the blue elements of this display begin to lose their integrity much faster than the other elements, so if you leave those blue elements on for a long period of time you will cause those elements to go bad and then from then on you have a pattern of burned out blue elements, causing burn in. so if this is true, apps that are meant to display bright static images for long periods of time could do everything in shades of red and green, leaving the blue elements off completely.
this will also hopefully mean that all the cool screen savers from the 90s will be given new life, and maybe we can even have a new renaissance of screen savers
I made the mistake of buying an OLED TV to use as a computer monitor last year, and today there are multiple areas of the screen where burn-in marks are visible from things like the taskbar, window title bars, window separators from tiled arrangement, etc.
It's a real shame because OLED has otherwise terrific properties as a display technology, and looks downright mind-blowing in a dark room where the infinite contrast from the lack of a backlight shines through. But because of the burn-in issues I've experienced, I can't in good faith recommend it as a long-term investment for use cases where you're likely to have static images on the screen for prolonged periods of time (smartphone and computer displays).
Anyone aware of other promising display technologies that can achieve the same levels of contrast without the downsides of the burn-in risks associated with OLED?
I noticed the burn in on my button bar of my Samsung S8, and finally understood why they didn't let me have a fully black navbar. I had installed a custom Navbar app to make it black; now that area is lighter than the rest.. fortunately not too be yet, but I'll be careful about apps like Google Auto going forward.
If my impression is correct, it must be a different phenomenon than the one you’re describing (which I’ve also always heard stttributed to OLEDs), where subpixels will output less light over their lifetimes (and perhaps the dimming-over-time curve is different for different colors).
In software it would boil down to one final compositing step to compensate.
Is this a technique that's used often? I'm curious what the cost of such a step would be. How much lag would it cause?
In portrait mode, a video would be brighter in this section. Plasma had the same problem. The pixels age and dim since they're the light source. There's no backlight. Please stop calling it burn in.
The status bar elements also seem like a large risk, as some pixels tend to not change.
I also can definitely notice a ghosting effect while reading and scrolling text at the same time.
I ran one of those "burn in fixer" solid color pattern apps for almost 24 hours(which i know have hit or miss efficacy) and it subdued it, but it's still very clearly visible.
But you could imagine that Apple records sub pixel usage and calibrates the display accordingly, so any sub pixels that are over-exposed to could be calibrated accordingly. But that would also mean some color distortion.
