[General Questions and Answers] Biker1:
I must be of the Rare Breed of those Owners whose Super Amoled Plus Screen is Fantastic, in Real Life ;)

Anyway, here's a little info about the current Display Technology:

Display technologies

Smartphone displays, like notebooks and tablets, are all based on LCD (Liquid Crystal Display) technologies. LCD has a fast refresh rate, which makes it great for mobile technologies that require bright displays with low power consumption.

TFT LCD — thin film transistor displays are easily the most common in smartphones at this time, though manufacturers are paving the way for newer, better performing screen technologies. TFT LCDs are often used in laptop displays as well.

Advantage – Cheap to make, most commonly used screen.

Disadvantage – Aging Technology, Not as bright or clear as other display technologies.

AMOLED — active matrix organic light emitting diode is one of the prominent up and coming display technologies looking to take over from TFT displays.

AMOLED screens are visibly more colourful than TFT displays and have a lower power consumption with thanks to the intriguing fact that the colour black is produced by the OLED being switched off. AMOLED screens have been used by Samsung, HTC, Nokia and Dell to name a few, and continue to be in high demand. They give off clear, bright and sharp images as seen in the images below. The potential problem with AMOLED screens is that they are quite poor in direct sunlight, and the screen will be close to unusable.

Advantage – Bright and clear quality, Low power consumption for screens.

Disadvantage – Almost un-viewable in direct sunlight, Display can appear pixelated.

The top pictures are LCD, the bottom two are AMOLED (Notice the screens below have a more ‘vivid’ color)

Super AMOLED — Samsung has positioned itself at the forefront of mobile display technologies producing its “Super” variant on the AMOLED display. By combining the touch panel and the top layer of glass, Samsung has created a screen that is visibly more vibrant than previous AMOLED screens, and more usable in direct sunlight.

Advantage – Everything AMOLED is but better, great for watching videos on.

Disadvantage – Still poor in direct sunlight, but better than regular AMOLED.

Super AMOLED Plus – Another Samsung fortified screen technology, which is available on the latest Samsung Phone Models. It is an advanced version of the Super AMOLED technology with better colour reproduction and scaling. Not as bright as Super AMOLED, but better. More subpixels are crammed into the screen tech, allowing it to be more pleasant for your eyes.

Advantage – Amazing color reproduction, better viewing angles.

Disadvantage – Not good enough in the sun yet, colours can seem washed out on larger screens.

AMOLED CBD — A Nokia only technology in which their latest phones use an AMOLED Clear Black Display (CBD) screen which results in deep blacks. A CBD displays blocks incoming light reflections and so perform better under direct sunlight. Generally considered on par and sometimes better with Super AMOLED Plus with superior contrast and colours.

Advantage – The best screen under direct sunlight, deep blacks.

Disadvantage – Does not take full advantage of AMOLED features.

Super LCD (SLCD) — another contender for screen dominance is Super LCD. A variant of traditional LCD technologies, SLCD offers better contrast and warmer colours than older LCD displays, but is said to drain more power than AMOLED displays.

Advantage – Cheaper to produce than AMOLED displays, Works better in direct sunlight over AMOLED.

Disadvantage – Drains more power than AMOLED displays, not as bright as AMOLED either.
