What is AMOLED?
[[File:Samsung AMOLED.jpg|thumb|AMOLED displays ([[Samsung Galaxy Note 10]])]]'''AMOLED''' (Active Matrix [[Organic light-emitting diode|Organic Light Emitting Diode]]) is a display technology mainly used in [[Mobile phone|mobile phones]], [[Television|televisions]] and other [[Electronics|electronic devices]] with a screen. An AMOLED display uses an active matrix of organic light-emitting diodes (OLED) that emits light when an [[Signal (electrical engineering)|electrical signal]] is present. As of 2008, AMOLED technology was used in phones, media players, and [[Digital camera|digital cameras]]. They are now being used more in low-power, cheaper and large-sized applications as well. == Advantages == {{Multiple image | align = right | direction = horizontal | caption_align = center | image1 = Samsung foldable phones.jpg | image2 = Samsung foldable smartphones.jpg | footer = Samsung [[foldable smartphone]]s | total_width = 350 }} OLEDs work like [[LED]]s except the diodes in OLEDs are thinner. Other type of displays, such as [[Liquid crystal display|LCD]]<nowiki/>s, require an external light source (backlighting) to illuminate the screen whereas OLED displays do not. [[Energy efficiency]] is also an advantage of AMOLED displays. It is more energy efficient than LED and other types of displays. This is because AMOLED displays generate less heat while emitting light, allowing for a more efficient energy transfer. It is energy efficient in its ability to consume less power as well. It can be utilized well for portable consumer electronic devices, where good battery life is essential. Because of this efficiency, AMOLED displays can also be considered eco-friendly. Compared to other types of displays, AMOLED displays can produce high refresh rates although LCD and IPS displays lead in that specific area. AMOLED technology also allows for bending displays, which manufacturers use to make bezel-less screens that bend behind the display. == Disadvantages == In previous days, AMOLED displays were prone to screen burn-ins
