What is the full form of AMOLED?

The full form of AMOLED is Active-Matrix Organic Light-Emitting Diode.

It is a hybrid display technology used in most modern devices such as mobile phones, laptops, televisions, etc. It is made from organic material that emits light when electricity is connected to them. AMOLED is based on pixels made of tiny red, blue and green organic material-based light-emitting diodes (OLEDs).

Active matrix denotes a thin film transistor (TFT) system in which each individual pixel luminesces on activation and the scree is drawn all at once each time it refreshes. A more responsive image at a wider range of viewing angles than passive matrix displays. Samsung popularized the use of this technology and it has since become a standard feature of some of its flagship smartphones and tablets, as well as digital cameras and smart televisions.

AMOLED Working

The continuous current flow is controlled by at least two TFTs at each pixel, with one TFT to start and stop the charging of a storage capacitor and the other to provide a voltage source at the level needed to create a constant current to the pixels. The colours that the pixel has, are light so the screens don't have to be backlit.

AMOLEDs are lighter as well as thinner and much more durable than any other technology out there. It also reduces power consumption. It doesn't require the backlight to provide brightness.

AMOLED Variants

Various variants of AMOLED are:

Super AMOLED
Super AMOLED Advanced
Super AMOLED Plus
HD Super AMOLED
HD Super AMOLED Plus
Full HD Super AMOLED
Quad HD Super AMOLED

AMOLED Advantages

The advantages AMOLED posses over other technologies are:

Higher Refresh rate
Puts less strain on the eyes
Low Power consumption
Produces brighter colours
AMOLED is thinner and lighter
Doesn't generate much heat
Made of organic material which is energy efficient and eco-friendly

AMOLED Disadvantages

Some of the disadvantages associated with AMOLED are:

Cost is very high
Have shorter life span than LCD/LED screens
Gets easily damaged by water
An AMOLED display is difficult to view in direct sunlight due to reduced maximum brightness and lack of backlighting.
