They work under the same principals as LCDs except they use organic diodes to produce light which have off states to produce deep blacks leading to vibrant colors via the contrast, and they save battery power since each pixel in a picture with dark colors is in an off state or is technically a turned off pixel (No power used) or a low power state, also each AMOLED pixel produces it's own light, manufacturers provide backlights to boost the existing lighting in outdoor scenarios, with an option to turn the additional lighting off...
these are the qualities tht make AMOLEd desirable vibrant colors and low power usage...
CRTs use an electron gun to fire electrons at the screen; that react with the phosphorous coated front display to produce light..
c'mon they teach this in physics class, high school to Uni... u got to be kidding me with tht loong a** answer tht makes no sense!!!
LCDs OLEDs AMOLEDs are based on crystal manipulation technology and are safe for ur eyes
CRTs are miniature particle accelerators tht smash electrons to a screen converting their energy to light energy via reacting with phosphorous coatings... n they aren't tht great for ur eyes a below 50Hz CRT can cause Nausea n headaches!!!
Hope u learn't something...

Power consumption - most of web pages have white background:
While an OLED will consume around 40% of the power of an LCD displaying an image which is primarily black, for the majority of images it will consume 60–80% of the power of an LCD - however it can use over three times as much power to display an image with a white background[55] such as a document or website. This can lead to disappointing real-world battery life in mobile devices.

Before buying the phone please make sure if its camera is zooming/not. Please check if any softwares, exe files could be downloaded. Please check if it supports qwerty keyboard.

Why gsmarena mocks apple, fakes ratings and promotes these buggy samsung and htc phones? Did they ever used the GPS on Galaxy and read this forum on its stupid screen? Maybe it has to do with anti-american trend to trash apple, an american icon.

Maybe, in the future, AMOLED will improve. So far, AMOLED is definitely worse than a good TFT - ISP with LED back lit.
Related to the usage of metal for light separators, it doesn't matter whether it is metal of non metal material. In fact, inclusive the metal, if it is very thin, it is transparent to light. Besides, the metal usually reflects the ambient light so if all sub pixels are off then you wish the screen to be black not silver as it may look if the pixels are separated by a metal grid like a very fine net from metal wires.
Another factor that has to be consider for this Super AMOLED, the light directly beams into eyes from its source which is OLEDs. All natural vision of human eyes is when the light comes from reflections of light, generated by sun or lamps, over objects: the photon beams don't directly get from source into eyes; also the beam of phones is not reflected as you may think: you don't get back through reflection the original photons from source; the phones are not as ping-pong balls cast back by objects which they hit; the beam is absorbed by objects, converted in energy and the objects emit other photons back in a sub spectrum of the original beam, lower intensity and broader uniformity over object surface thus giving color to objects and thus protecting the eyes from artificial light that maybe dangerous for human retina when comes from artificial powerful punctiform sources. The LED back lit from TFT is diffused over a white panel then by reflection passes though liquid crystals and get into eye so it is a reflected light, not the original light. OLED like CRT colored phosphors or plasma's pixels directly beam the light into eyes thus you are not protected by ultraviolet emissions and high energy photons which make lesions in organic tissue.
So, TFT displays are healthier than AMOLED and CRT and plasma displays.

Anonymous, 25 Jul 2010Hopefully for you, Dell's phone will be a good replacement ... moreIt does not mean you should have big pocket to have the Dell Streak, buying a case will be nice without having a big pocket. Morons and false news reporters about iPhone 4 need to be quiet and talk about something else. Now is Samsung Galaxy GPS. Morons always find minor things to complain about.

Anonymous, 22 Jul 2010Let to give a chance to Galaxy; iPhone 4 is too good.I just bout my Samsung Captivate on July 22, 2010 because of the Android noise people have been talking about. I like the 4.0" screen and Super Amoled displays, Widgets and few features that are not available on the iPhone 4. I decided to buy the Samsung Captivate as a second phone to my iPhone 4.
