FullArray Local Dimming: Revolutionizing Digital Signage Display

As the demand for ultra-clear, high-impact digital displays grows, businesses in retail, hospitality, transportation, and corporate sectors are looking for the next evolution in display technology. Enter Full–Array Local Dimming (FALD)-a breakthrough that dramatically enhances screen contrast, brightness, and overall image performance.

In this article, we explain what FALD is, how it works, and why it’s quickly becoming a must-have feature in premium digital signage solutions.

What is Full-Array Local Dimming (FALD)?

Full-Array Local Dimming is an advanced LED backlighting technology used in LCD displays. It involves two major innovations:
• Full-Array: LEDs are placed evenly behind the entire screen (not just on the edges).
• Local Dimming: The backlight is divided into multiple zones that can dim or brighten independently

Together, these features create a display capable of producing deeper blacks, brighter whites, and dramatically higher contrast, resulting in richer, more lifelike visuals.

How Does FALD Work?

To understand how FALD works, it’s useful to compare it to other backlighting methods.

Edge-Lit LED Displays:
In these displays, LEDs are placed along the edges of the screen, and light is diffused across the panel using a light guide.These displays are thinner but often struggle with uniformity and contrast.
Direct-Lit (Non-dimming):
Here, LEDs are placed directly behind the screen but are not controlled in zones. They offer better uniformity than edge-litdisplays but do not significantly improve contrast.
Full-Array Local Dimming (FALD):
FALD builds on the direct-lit concept but introduces zones-sections of the backlight that can independently dim or brighten.For example, in a dark scene with a bright starry sky, the areas behind the stars remain bright, while the background is dimmed. This results in higher contrast, reduced haloing, and more realistic images.
Traditional LED-backlit displays illuminate the entire screen uniformly, even when only part of the screen is showing bright content. This results in:
• Washed-out blacks
• Limited contrast
• Light bleeding into dark areas

FALD solves this problem by dividing the backlight into individually controlled dimming zones.

Key Benefits of Full-Array Local Dimming for Digital Signage

Here’s why FALD technology is ideal for commercial digital displays.

Improved Contrast Ratio

FALD drastically improves contrast by allowing black areas of an image to appear darker without compromising the brightness of lighter areas. This is especially important for digital signage used in environments with varying ambient light conditions such as shopping malls, airports, or train stations.

Deeper Blacks and Brighter Whites

Traditional LCDs often suffer from “greyish blacks” due to constant backlighting. With FALD, when an area of the screen is supposed to be black, the backlight in that zone can be turned off or dimmed, creating much deeper blacks and enhancing realism.

Enhanced Visual Impact

In digital signage applications, grabbing attention is paramount. FAlD enables content to look more vibrant and engaging,making it ideal for high-end advertising, luxury retail, and premium showrooms.

Better HDR Performance

High Dynamic Range (HDR) content benefits greatly from FALD. The ability to show both dark shadows and bright highlights simultaneously makes HDR visuals more impactful and closer to what the human eve naturally perceives.

Energy Efficiency

While FALD does use more LEDs than edge-it displays, its zone-based dimming can be more energy efficient overall. When large areas of the screen are displaying dark content, those zones use less power compared to keeping the entire backlight at full brightness.

Minimized Light Bleed and Haloing

Light bleed (unwanted light spilling into dark areas) and haloing (bright rings around dark objects are common issues in non local dimming displays. With FALD, these artifacts are significantly reduced, resulting in cleaner image quality.

Ideal Applications for FALD in Digital Signage

FALD is perfect for premium and visually demanding environments such as:

Luxury retail showrooms
Corporate lobbies & boardrooms
Transportation hubs (airports, metro stations)
Hospitality and high-end QSRs
Museums, galleries, and exhibitions
Cinemas,entertainment venues, and stadiums

Wherever image quality makes a difference, Full-Array Local Dimming displays deliver.

Why FALD is the Future of Commercial Displays

As digital signage shifts from static screens to dynamic, media-rich platforms, visual quality becomes a competitive differentiator. Full-Array Local Dimming enhances the user experience by:

Making your content more immersive
Improving brand perception
Increasing customer dwell time
Enhancing message clarityin both light and dark environments

Whether you’re showing promotions, product videos, or informational content, FALD gives your message the impact it deserves.
