AMOLED stands for “Active Matrix Organic Light-Emitting Diode.” It is a type of OLED (organic light-emitting diode) display technology that is used in a wide range of electronic devices such as smartphones, tablets, laptops, televisions and digital cameras.

AMOLED was developed in 2006. Samsung SDI was one of the main investors in the technology, and many other display companies were also developing it.
In an AMOLED display, each pixel is made up of an organic material that emits light when an electric current is applied. This allows each pixel to be turned on and off independently, resulting in deep blacks and high contrast. Additionally, AMOLED displays are known for their wide viewing angles and fast refresh rates.
Benefits and Advantages
AMOLED displays can provide higher refresh rates than passive-matrix, often have response times less than a millisecond, and they consume significantly less power. This advantage makes active-matrix OLEDs well-suited for portable electronics, where power consumption is critical to battery life.
One of the key benefits of AMOLED displays is that they are self-emissive, meaning that each pixel generates its own light. This allows AMOLED displays to have perfect blacks, as the pixels can be turned off completely when displaying black, resulting in a contrast ratio of infinity. This is in contrast to LCD displays, which rely on a backlight to produce light and therefore cannot achieve perfect blacks.
Another benefit of AMOLED is that it consumes less power compared to LCD displays, making them more power-efficient and longer-lasting.
Disadvantages
AMOLED displays may be difficult to view in direct sunlight compared with LCDs because of their reduced maximum brightness.
The organic materials used in AMOLED displays are very prone to degradation over a relatively short period of time, resulting in color shifts as one color fades faster than another, image persistence, or burn-in.
Overall, AMOLED is a display technology that offers a superior viewing experience with deep blacks, high contrast, wide viewing angles, and fast refresh rates.
