It is no doubt that you have heard the word AMOLED or Super AMOLED display before. It not only about technology but these words are frequently used in smartphone marketing to get your attention too. However, most of us do not know what the AMOLED technologies mean and how they affect our Android handset.

What is an AMOLED display?

Most likely, you hear the term ‘Super AMOLED’ when a Samsung handset is being talked about. Super AMOLED is specifically for Sammy’s own version of AMOLED display.

The AMOLED display is a popular choice among lots of Android manufacturers. Each manufacturer has its own version of the AMOLED display. For instance, Samsung has a Super AMOLED Display while the Motorola has a Super AMOLED Plus display.

The AMOLED displays do not need a backlight. The AMOLED displays produce a deep black light that lets the pixels to completely shut off. You are actually saving the battery life and electricity this way.

What is a Super AMOLED?

There are not too many differences between the Super AMOLED display and the regular AMOLED display. The regular AMOLED have a capacitive touchscreen which is a separate layer of the display itself. On the other hand, in Super AMOLED technology, the capacitive touch screen is fused in the display itself.

Super AMOLED technology thus means that Sammy can even manufacture thinner displays. This design also uses sales power and also reflects less light providing a better view of your handset’s display even when it is under direct sunlight.

How does an AMOLED display work?

The OLED-Displays describes clearly how an AMOLED display work.

“Active matrix (AM) OLED displays stack cathode, organic, and anode layers on top of another layer – or substrate – that contains circuitry. The pixels are defined by the deposition of the organic material in a continuous, discrete “dot” pattern. Each pixel is activated directly: A corresponding circuit delivers voltage to the cathode and anode materials, stimulating the middle organic layer. AMOLED pixels turn on and off more than three times faster than the speed of conventional motion picture film – making these displays ideal for fluid, full-motion video.”

What you should know is that an AMOLED display offers an incredible viewing experience, whether we are talking about pictures, games, or videos. The image is more superior than the one which is experienced on handsets using a different screen technology.

The AMOLED display also offers a faster response time and higher refresh rates.
