Before we get into the nitty-gritty, let’s talk about what we’re going to cover. We’ll go through the steps of how full array local dimming works to enhance your viewing experience. It’s like adding an extra layer of awesome to your TV.

Step 1: Understand the Basics of Your TV’s Backlight

The first step is to realize that behind your TV screen there’s a bunch of lights. These lights are what make your TV picture bright and colorful.

Step 2: Learn About Zones

Full array local dimming divides these backlights into different areas or ‘zones’. Each zone can be dimmed or brightened independently from the others.
