Introduction to Local Dimming

Local dimming is a feature found in many modern TVs, particularly those with LED or OLED panels. It allows the TV to dynamically adjust the brightness of different areas of the screen, resulting in improved contrast, deeper blacks, and a more realistic picture.

How Local Dimming Works

Local dimming works by dividing the TV's backlight into multiple zones. Each zone can be adjusted independently, allowing the TV to create a more nuanced and detailed picture. For example, in a scene with a bright sky and a dark forest, the TV can dim the zones corresponding to the forest while keeping the zones corresponding to the sky bright, resulting in a more natural and immersive image.

Types of Local Dimming

There are several types of local dimming, including:

Type	Description

| Edge Lit | The backlight is located at the edges of the screen and is divided into zones that can be adjusted independently. | Full Array | The backlight is located behind the screen and is divided into a large number of zones that can be adjusted independently. | OLED | OLED panels do not require a backlight and can adjust the brightness of each pixel independently, resulting in true blacks and infinite contrast.

Benefits of Local Dimming

Local dimming offers several benefits, including:

* Improved contrast and deeper blacks * Increased color accuracy and vibrancy * Reduced blooming and halo effects * Enhanced overall picture quality
