Mini-LED Local Dimming Technology
Mini-LED Local Dimming Technology
Mini-LED full array local dimming (FALD) is an advanced backlighting technology that enhances contrast and picture quality in LCD displays. By dividing the backlight into multiple zones, each with independently controlled LEDs, local dimming allows for precise brightness adjustments.
This targeted control enables darker areas of the screen to achieve deeper blacks while keeping bright areas vivid, resulting in sharper contrast and more lifelike visuals.
Why Choose Local Dimming
Exceptional Contrast: Thousands of dimming zones ensure deep blacks and vibrant colours. This is critical for applications like medical imaging and automotive displays where high contrast and visual clarity are crucial.
Power Efficiency: Mini-LEDs allow precise brightness control, optimising power consumption, particularly valuable for portable devices where high performance and extended battery life are key.
Durability and Longevity: Unlike OLEDs, Mini-LEDs resist burn-in and maintain consistent performance over time.

Types of Local Dimming Technologies
Not all local dimming implementations are the same. The choice of technology significantly impacts the display’s performance. There are three primary types:
Edge-Lit Local Dimming
LEDs positioned along the screen's edges direct light through a diffuser to create dimming zones. While cost-effective, they lack precision, often resulting in brightness bands and limited control over specific screen areas.
Full Array Local Dimming
FALD features a grid of mini-LEDs with individually controlled dimming zones, offering exceptional contrast, deeper blacks, and HDR performance by synchronizing brightness with screen content.
Direct-Lit Local Dimming
Using larger LEDs with fewer zones, direct-lit systems provide better performance than edge-lit designs but less precision than FALD, leading to potential light leakage and reduced contrast.
