AMOLED screens are a type of display technology that uses an organic compound to produce light, resulting in thinner, lighter, and more energy-efficient screens.

Organic compounds used in AMOLED screens are sensitive to oxygen and moisture, which can degrade their performance over time.

AMOLED screens are commonly used in smartphones and smartwatches, where their high contrast ratio and fast response time make them ideal for displaying vibrant colors and dynamic content.

What is AMOLED?

AMOLED stands for "active-matrix organic light-emitting diodes." It's a special technology that includes thin strips of thin-film transistors (TFT) behind each pixel in AMOLED displays.

These transistors help electricity move more quickly across the display, allowing each pixel to be activated faster. This results in smoother and more responsive images.

The term AMOLED means Active-Matrix OLED, with the 'active-matrix' part referring to the driving electronics, or the TFT layer. It's what enables large size and high resolution displays.
