Acronyms aren't always easy to understand, especially in the world of home electronics. This article explains a light source used in various electronic displays.
OLED screens, how do they work?
OLED, an advanced form of LED, stands for organic light-emitting diode. Unlike LED, which uses a backlight to provide light to pixels, OLED is defined as relying on an organic material made of hydrocarbon chains to emit light when it comes into contact with electricity.
This approach has several advantages, most notably the ability for each pixel to produce its own light. This creates an infinitely high contrast ratio, meaning that blacks can be completely black and whites extremely bright.
This is the main reason why more and more devices are using OLED displays, including smartphones, wearables, TVs, tablets, monitors, and digital cameras. Among these devices and others, there are two types of OLED displays that are controlled in different ways, called active matrix (AMOLED) and passive matrix (PMOLED).
