OLED has virtually off blacks and great contrast as a result. It's also very thin. The problem is that it consumes more power than a comparable LCD in white situations, isn't quite at the same pixel density yet, and has some issues with pixel lifetimes (although that has improved a lot).
The display on the S3 for example is very bad in that regard, it does not have true blacks, nor did the S2 for that matter. The diodes are still being fed current and are never shut off, no matter what people will tell you. The S3 is atrocious as an OLED screen in this regard as the backlight-bleed (for no better name of it, I'm aware it's not technically correct) is very present.
Amoleds have much better response times also, they are
very inefficient
Response time which is totally irrelevant as we're driving it at 60Hz anyway and the response time is dictated by the display driver not the screen display itself.
Power efficiency is also more a design and engineering problem than an actual physical constraint of using OLEDs.
This research paper goes into of the possible efficiency gains just by simple display algorithm change in how the diodes are powered, and what voltage and current they are fed. We have 20 to 50% efficiency gains without change in hardware and only minor colour accuracy hit at the same brightness output.
Ah, can see your point!
Hadn't caught up on all the discussion related to the cameras, whoops.
Can you calibrate the screen manually on the Samsung Galaxy SIII? The main advantage of OLED is real blacks at the expense of brightness and battery consumption, right?
You can calibrate the screen through
mDNIe profiles, this involves of course either configuration through the source code and kernel/driver recompilation or hooking a sysinterface to the respective registers for user-space real-time configuration. There are about 30 registers each changing a display property. These are currently undocumented for outside people and in need of reverse-engineering to get a proper product / calibration method.
Another advantage that may not be clear to the end-user but more interesting to the manufacturers is the display thinness, allowing equipment of larger internal components, or thinner devices.
Because part of what makes a product a product is the reason consumers would like/buy a product...whsts the point in having a ton of camera features that can't be used with going through various menus and getting thread menu out? The thing that makes the lumia great is it takes the best photos (I'm assuming here) and is total easy to use.
It takes 3 clicks on the camera interface to enter night mode or just two if you shortcut it onto the quick-setting bar. And unless you are running in and out of the house in the middle of the night, there is no need to further change this mode. It is an idiotic argument for the measurement of empirical capabilities or worth of a product. A review of quality of a product is a bad review of quality of a product if it does not encompass or at least mention optional capabilities. By that rhetoric let's just get rid of any and all settings in technology for the sake of simplicity, most end-users won't use it right?
