Understand Edge Lighting Technology

Edge lighting is a fundamental aspect of many Samsung TV models, contributing significantly to their sleek design and impressive visual performance. To effectively address edge lighting issues, it’s crucial to have a basic understanding of how this technology works and its impact on your viewing experience.

What is Edge Lighting?

Edge lighting refers to the placement of LED lights along the edges of the TV screen, typically at the top and bottom or all four sides.
These LEDs illuminate the entire screen by dispersing light across a special diffuser panel, creating a uniform and bright image.

Advantages of Edge Lighting

Edge-lit TVs are often thinner and more energy-efficient compared to other lighting technologies used in televisions.
This technology allows for better control over local dimming, enhancing contrast and black levels in specific areas of the screen.

Common Edge Lighting Issues

Uneven brightness across the screen, often manifesting as lighter or darker areas near the edges of the display.
Light bleeding or clouding, where light appears to leak from the edges into darker areas of the image.

Impact on Viewing Experience

Edge lighting problems can significantly detract from the overall picture quality, affecting contrast, color accuracy, and immersion.
In severe cases, these issues can make certain content unwatchable, particularly in dark scenes or when viewing in low-light environments.
