Local dimming - what is it?

You often encounter local dimming in connection with LED TVs. In our practical tip, we explain what is behind it and how you use the feature.

Local dimming for LED TVs

Local dimming is a special form of backlighting for TV screens.

• LED screens are illuminated from behind. There are two types: the Edge LED, in which LEDs are attached to the edge of the screen and illuminate the panel, and local dimming.
• With local dimming, also known as direct LED, LEDs are distributed behind the entire surface of the panel. These can be dimmed or switched off individually. This creates an image in which each individual LED's brightness can be regulated or switched off.
• The advantage of local dimming is the higher contrast and the deeper black, in addition, the image illumination is seamless and more homogeneous compared to the Edge LED.
• In return, the screen cannot be so flat and the price for such an LED TV is slightly higher.
