We’re going to break down three concepts related to smart TVs that will help you better understand the device in your living room: WebOS, AMOLED, and POLED. Although they’re often lumped together, WebOS refers to the software in smart TVs, while AMOLED and POLED refer to the display technologies in the device.

This is probably the easiest term out of the three because it’s different. WebOS is an operating system used by LG in its smart TVs that allows users to control their TVs. Based on Linux, it’s served as LG’s TV platform for more than a decade and also powers some of the company’s other devices, including its refrigerators and projectors.

WebOS is basically a central hub that allows you to access the device’s different functions and manage your content. Through its main dashboard, you can access the apps on your TV and connect to the Internet and other compatible devices, including smart speakers. It comes with its own browser, which means you can surf the web on your TV.

While you can use WebOS to connect directly to your phone and stream content to your TV, it comes preinstalled with popular streaming apps such as Netflix and Disney+, allowing you to access them directly on the device.

Before we go any further, it’s important to note that both AMOLED and POLED are types of OLED displays. Though they produce different images, they are based on the same underlying technology.
