Active Matrix Organic Light-Emitting Diode (AMOLED)

Definition - What does Active Matrix Organic Light-Emitting Diode (AMOLED) mean?

Active matrix organic light-emitting diode (AMOLED) is a light-emitting and thin-film display technology in which electroluminescent organic compounds are placed on a base layer. With significantly less power consumption and with no backlight requirement, it is favored in displays for portable electronic devices, battery-powered devices and large displays.

Techopedia explains Active Matrix Organic Light-Emitting Diode (AMOLED)

Active matrix organic light-emitting diodes make use of a thin-film transistor that is used to control the pixels. They consist of organic molecules, anode and full layers of cathode. The thin-film transistor array helps in determining the pixels to be activated to form the image.

There are many advantages in using AMOLEDs. Compared to other display technologies, AMOLEDs have a higher contrast ratio and a faster response time. They are lightweight, provide great flexibility and are also capable of low-temperature processing. They have high light efficiency and surpass passive-matrix organic light-emitting counterparts by providing the same performance but consuming significantly less power. AMOLEDs have an unlimited viewing angle and are also self-emissive. Their production cost is potentially the lowest among existing technologies, and they can also display a wider range of colors than LCD. AMOLEDs are favored in portable electronic devices because their battery power consumption is significantly less. For the same reason, they are favored for large displays such as billboards, electronic signs and large-screen televisions. The fast refresh rates of AMOLEDs also make them suitable for videos.
