    Samsung deserves a big thank you for pioneering OLED tech in the mobile space. Because of their constant push for bleeding edge hardware, other manufacturers can now reap the benefits when it comes to the display in their mobile devices. And fanboys no longer have to pretend they prefer a1080P LCD screen. Ohhhhhhh, did I just go there? ;)

    Wait, AMOLED's now cheaper?

    Well, it's confirmed. Apple are definitely going to have AMOLED in the iPhone 7. :p

    thank god.

    does amoled suffer from unevenness in brightness and color like lcds do?

    there isnt a single iphone 6s with an even white color temperature across the screen. presumably it has something to do with backlight, blue leds and yellow phosphor.

    does amoled suffer from any other issues?

    No light bleed to deal with from the edge of the screen either.

    Does OLED have issues? Sure. Leave a stagnant image on a screen for a month or more and you are bound to get "ghosting". The image persists. It is rectifiable, unlike with " burn-in" on old plasma and CRT screens.

    What's wrong with a 1080P LED display? I've had every phone under the sun, and its not that drastic of a difference. Hell, I have a 6S Plus/Nexus 6P/Note 5 near each other right now. Yes, the Note 5 looks the best out of the 3, but its not "omg, it looks so much better!" But, I'm glad Apple is going to Amoled in 2017, though.

    When you look at a LED 1080p screen and then an AMOLED 2k-4k screen, there is a dramatic difference when looking at video or gaming. 4K especially, because you get an almost 3d effect on screen. Looking at a grid of icons or website like this, not so much.

    No such thing as led display. That just marketing. They're all LCDs. Only true led displays are oled.

    OLED panels currently have generally worse uniformity than LCD, including the current-gen Samsung phones. A gradient with black crush across the panel is extremely common. Many users don't notice it, but it's hard to find a unit that doesn't show this effect.

    The current Samsung OLED panels also use PWM dimming, which means they control brightness by changing flicker rate instead of actually dimming. This can be irritating to the eyes and produces a stroke effect when the phone is moved, but again many people don't seem to notice. Apple is pretty serious about using flicker-free LCD panels but many other manufacturers use PWM with LCD as well. PWM is cheaper to implement, and in the case of OLED it may also reduce power to "flash" the screen at high brightness instead of regulating a constant output.

    There are some minor issues with low brightness pixel response times which can be seen as purple trailing effects.

    And most importantly the current batch of phone OLED panels are "pentile," which means their true resolution is not nearly as high as the advertised/rendered resolution. Some details in the Anandtech Note 4 review (still using the same pixel layout and resolution in the current panels): http://www.anandtech.com/show/8613/the-samsung-galaxy-note-4-review/4

    That pentile layout is generally considered to be a workaround for the uneven aging of the different colored subpixels on OLED, which brings up another point: Burn in.

    My point isn't to say that these displays are in any way bad; They look amazing even with all these negatives. The point is simply that there ARE downsides to the technology in its current state. The real future of display tech is probably micro-LED, which uses the same idea (individual diode for each pixel) and uses miniaturized traditional LEDs which don't suffer from as much burn-in as OLED.

    well, it safe to say apple has its reason (and i bet good ones) not to jump the oled train yet. oled are only partly better than lcds. for now.

    but what i'm most curious about when (and if) are we going to get screens with uniform white. i have never seen a screen with uniform white in my entire life? is such a thing possible?

    one would think if all of those manufacturers are inclined to make 4k 2inch screen, they would save some engineering expertise for uniformity but i guess not. unbelievable. really.

    also, how come anandtech and other sites never mention display uniformity issues. there isnt a single iphone 6s (dont know about the plus) with a uniform display. thats a 700bucks phone with 4.7 inch display. and 750p while we're at it. appalling really.

    Quantum Dot LED will supposedly have a uniform, true white screen.

    Please do some research before you try to spread misinformation.

    It's called LED because the backlight is provided by LED technology.

    Not sure how long you've been following display tech but I have been an enthusiast for over 16 years.

    Here is a brief history:

    LCD with CCFL is introduced as consumer display by Sony as they continued to lose marketshare in the plasma industry.

    Samsung Markets EDGE lit LCD displays as LED TV's. Consumers see thin displays coupled with marketing are start calling them "LED TV's"

    Publications such as CNETS David Katzmier and to a lesser extent others such HD GURU, HD shootouts in Scarsdale and enthusiasts and pro calibrators from AVS forum inform people of the differences.

    Full array LED with local dimming LCD is introduced by samsung

    The first true consumer LED (OLED) is brought to market by Sony in "11 form (I was actually in a Best Buy when local news was reporting on it with a blue shirt).

    So, for the purposes of not "misinforming" people, you yourself noted that its a backlight. The display itself is the LCD portion.

    To drive the point home, did anyone call them CCFL TVs? No they did not. So let's not allow others fall victim to marketing propaganda such as calling them "LED" tvs when they aren't/weren't. Let's ensure the "misinformation" stops here. ;)

    Telling people to not call it LED is pretty much a 180 from this post. Nobody ever calls it LED LCD - the name LED is synonymous with "LED-backlit" in this industry. You should know that as a self-proclaimed LED enthusiast. Unless you're really going to go around yelling at everybody to call it an LED LCD?

    TL;DR: hey guys, you can call it an LED display as much as you want, most of us know what you mean. :)

    Would you like to go back and look at my original post? I said "no such thing as led display. That's just marketing. They're all LCDs. Only true led displays are oled". I never told anyone not to call something whatever they want. My second post says the same thing I did in my first but with 18 words instead of 200, that theres no such thing as led TVs, only oled. Hardly a 180. Also, seeing as the topic of discussion here is oled tech, it should be taken in to account that we should distinguish between the technologies as to not cause confusion to those" passing by ".

    I'm not an LED enthusiast but an A\V one. Distinct difference there.

    The only source of confusion here is yelling at people to not follow the established industry naming convention. I'm going to keep calling it as everyone else (except you, apparently) recognizes it, thanks. :)

    Did I use caps? Nope. So no yelling from me.

    The only one following the "established indsutry naming convention " here are people being led by the marketing departments, not what they're objective and scientific definitions are.

    I did recognize it, and just made a point of clarification seeing as we are discussing oled vs LCD (and also that the term used was one created by marketing). For one reason or another, you took issue with it.

    No idea. Not sure how far along the tech is from companies like Samsung? Won't get cheap until scaled for consumer use.

    While we're at it, can we stop appending "P" to 1080 and 720 when talking about resolution? I don't ever see 4KP or 5KP or even any odd lower resolutions that aren't 1080 or 720. Are any current displays interlaced?

    We're getting way off topic here but I will respond since I was quoted, but it will be my last.

    First off, the name game is and always will be something led by marketing Dept's to lure consumers in. This, probably more than anything else we have will be a constant.

    Second. Any discussion I have ever witnessed or been a part of, as they've pertained to resolution have always been in reference to the source, not the displays native resolution.

    Third. "Appending" p is still relevant when referring to resolutions such as 1080 as a lot of broadcast material is still 1080i. So if someone has a question about a TV they are interested in buying, and 95% of the content they will be watching is cable TV, then TVs ability to properly deinterlace is an important component in their purchasing decision.

    Fourth. The reason you don't see a "p" attached to 4k is because it is a progressive source by nature.

    Lastly, I won't even start with the whole 4k and uhd nonsense, lol.

    No, the fanboys/Samsung haters will turn a blind eye to this, and claim Samsung copied Apple with using AMOLED, lol, I've seen them claim some ridiculous things around here.

    Samsung has pioneered a whole lot of things, a lot of them go into the products the very haters who claim Samsung copied this and that use. :D funny world this is.

    I made this post previous in the HTC 10 thread. #133 However its relevant here.

    -----------

    "There is an assumption often used that amoled is best and yet other than maybe Samsung's flagships in my own experience owning so many others, amoled screens are more often than not very flawed. Color accuracy and calibration is often very much off compared to a very good LCD and moreover the white point is usually very much off point with majority of Amoled screens returning a very yellow hued screen. Some are worse than others yet all seem to exhibit this yellow tint (actually even Samsung's 2015 flagships had a pale yellowish whites, especially in basic mode which used to provide the more realistic colour balance previously). The Nexus 6P, yellow tinge, The Moto X Force, yellow tinge etc .... It just seems to be a factor in Amoled screens and personally i really dislike this warm white point. I have had to resort to using screen calibration apps (screen balance) to fix the yellow, but even then they still more often than not, don't match the clean neutral whites of a good IPS LCD.

    Likewise other than Samsung, who pushes screen brightness v.high, most Amoled screens are very poor in outdoor sunlight compared to LCD screens. A 2k screen that you can barely see the contents on whilst shooting photos is quite often a frustrating experience.

    An example here is the Moto X Style which people complained had moved to LCD and yet compared to its sibling the Moto X Force it actually has the nicer calibrated screen with the force being very yellow, and outdoor visibility is much better on the Style's LCD panel than the Force's 2K Amoled.

    So yeah, the technology is far from perfect to declare it automatically better because there are plenty of excellent LCD screens that offer better viewing experience than majority of Amoled screens outside of the Samsung flagship models."
