At Tailor Pixels, we launched dynamic backlight (Mini LED) displays. The dynamic technology enables LCD to achieve a million-level contrast ratio and superior color accuracy, and can provide more accurate performance with energy saving
We will tell you why Dynamic Backlight LCDs are the future and how they can outperform traditional LED backlight solutions.
Why Dynamic Backlight LCD?
Mini LED vs. Traditional LED
Ultra-High Brightness (500–3,000 Nits) – Perfect for Outdoor Displays
Outdoor application is a very common commercial display application scenario. Traditional LCDs struggle under direct sunlight; their brightness is hard to overcome the brightness of 1500 nits, but Mini LED Dynamic Backlight LCDs can achieve 500–3,000 nits of brightness, making them ideal for outdoor digital signage.
Million-Level Contrast Ratio – True HDR Experience
Unlike traditional LED backlights, which have limited dimming zones, Mini LED backlighting uses fine local dimming to dynamically adjust brightness. This results in deeper blacks (near-OLED levels) and brighter areas (enhanced HDR performance)
Significantly Improved Color Gamut – More Vibrant & Accurate Colors
Using white light or blue light plus quantum dot film (QD Film) to perfectly achieve a wide color gamut (up to 85-120% NTSC).
Energy Efficiency – 50% Lower Power Consumption
Under the same screen, the dynamic power consumption of Mini LED can be reduced by about 50% compared with traditional LCD backlight products.
How Mini LED Dynamic Backlight Works
The Core Concept: Local Dimming Zones
Unlike traditional LED backlights that illuminate the entire screen uniformly, Mini LED backlighting divides the display into hundreds (or even thousands) of tiny, independently controlled zones.
- Traditional LED: 10–100 dimming zones (limited contrast, light bleed)
- Mini LED: 144–2,000+ zones (precise brightness control per zone).
This allows darker blacks and brighter highlights simultaneously—key for true HDR performance.
Key Components
1. Mini LED Backlight Panel
Thousands of Mini LEDs are packed densely behind the LCD layer.
Each LED can be individually dimmed or brightened based on the image content.
2. Local Dimming Algorithm (2K/4K Processing Board)
A specialized processor analyzes the video signal frame-by-frame.
It calculates which zones need to be brightened (for highlights) or dimmed (for shadows).
Advanced algorithms prevent blooming (halo effects around bright objects).
3. T-CON (Timing Controller) & Driver ICs
The T-CON synchronizes the LCD panel and Mini LED backlight.
Driver ICs control each LED zone with ultra-fast response times (avoiding lag in fast-moving scenes).
Working Process
– Image Analysis
The processor scans the incoming video signal (e.g., a dark scene with bright headlights).
– Zone Activation
Only the Mini LEDs behind the “headlight” areas light up at full brightness.
LEDs in dark areas shut off completely, achieving true black.
– Real-Time Adjustment
As the image changes (e.g., a moving car), the algorithm dynamically adjusts each zone for smooth transitions.
– Final Output
The LCD panel modulates the light to produce the final image with deeper contrast and vivid colors.
Application and Options
The dynamic backlit LCD display delivers vibrant visuals and superior brightness, making it the perfect choice for commercial advertising machines, digital signage, and interactive kiosks.
It features enhanced color accuracy, wide viewing angles, and adjustable backlighting to ensure optimal visibility in any environment, from shopping malls to outdoor venues.
