AMOLED (Active Matrix Organic Light Emitting Diode) is a display technology primarily used in mobile phones, televisions, and other electronic devices with screens. It utilizes an active matrix of organic light-emitting diodes (OLED) that emit light when an electrical signal is present. AMOLED displays do not require an external light source (backlighting) like LCDs, making them more energy-efficient and capable of producing high refresh rates. Despite advantages like energy efficiency and high contrast ratios, AMOLED displays have faced challenges such as screen burn-ins and susceptibility to water damage due to their organic compounds. Manufacturers have addressed these issues through techniques like pixel shifting and sealing methods during manufacturing. Additionally, advancements like Super AMOLED technology by Samsung have improved sunlight visibility and power consumption, making AMOLED displays a popular choice in modern devices.
