OLED vs. AMOLED — What's the Difference?
By Tayyaba Rehman — Published on January 19, 2024
OLED (Organic Light Emitting Diodes) displays use organic compounds to create light. AMOLED (Active Matrix OLED) adds a layer of semiconducting film to control each pixel more precisely.

Key Differences
OLED, standing for Organic Light Emitting Diodes, is a display technology where each pixel is made of organic compounds that emit light when electricity is applied. AMOLED, or Active Matrix OLED, builds upon OLED technology by integrating a thin-film transistor (TFT) layer that allows for more precise control of each pixel, enhancing display performance.
In OLED displays, the illumination of each pixel is controlled directly by applying an electric current. In contrast, AMOLED displays use the additional TFT layer to manage each pixel's color and brightness more efficiently, leading to improved response times and power consumption.
OLED displays are known for their thinness, flexibility, and the ability to produce deep blacks and high contrast ratios. AMOLED displays share these benefits but often exhibit better performance in terms of color accuracy and refresh rates due to the active matrix technology.
While both OLED and AMOLED provide superior viewing experiences compared to traditional LCDs, AMOLEDs are generally more expensive due to their advanced pixel control technology. OLEDs, being the base technology, are more commonly found in a variety of devices including TVs and smartphones.
Energy efficiency is a notable feature of OLEDs as each pixel generates its own light, eliminating the need for backlighting. AMOLEDs further enhance this efficiency, particularly in displaying true blacks and reducing power consumption in dark scenes or modes.
