Display LEDs / Mini & Micro LEDs — Advanced LED Solutions for Industrial Applications

Application Overview

QUEENDOM’s Display LED portfolio spans Mini LED backlight solutions for premium LCD displays and emerging Micro LED technologies for next-generation direct-view screens. As display manufacturers transition from conventional edge-lit LED to full-array local dimming (FALD) Mini LED architectures, our precision die and advanced packaging technologies enable the 10,000+ zone dimming systems that deliver OLED-competitive contrast ratios while maintaining higher brightness and avoiding burn-in risks. The Mini LED chips (typically 100-200μm) require exceptional die placement accuracy (<±15μm) and consistent optical performance across millions of units — manufacturing capabilities that QUEENDOM has developed through partnerships with leading panel makers in Taiwan, Korea, and China. For Micro LED applications, our sub-50μm flip-chip devices support the massive parallel transfer processes needed for direct-view displays ranging from smartwatch screens to modular video walls. The GaN-on-Sapphire and GaN-on-Silicon platforms offer different cost-performance tradeoffs for various display sizes and resolutions. With color conversion technologies including quantum dot and phosphor-silicone systems, we support the wide-gamut (DCI-P3, Rec.2020) color performance required for HDR content mastering and broadcast monitoring applications.

Application Cases

Mini LED Backlight for 85-inch 8K TVs

A leading Korean TV manufacturer deployed our 180μm Mini LED chips in a 10,240-zone FALD system for their flagship 85-inch 8K LCD television. The 0.008-inch die pitch enabled 5mm OD (optical distance) with uniform luminance (ΔL<5%), achieving 4,000 nits peak brightness for HDR10+ content. The quantum dot color conversion layer delivered 95% DCI-P3 coverage with ΔE<1.5 color accuracy. Production scale reached 500K units monthly with Cpk>1.67 on critical optical parameters.

Micro LED Smart Display Module

A Chinese display startup integrated our 30μm blue Micro LED dies with red and green quantum dot color conversion into a 1.5-inch smartwatch display module. The 350 PPI resolution required <±10μm die placement accuracy achieved through laser mass transfer. The resulting display delivered 2,000 nits brightness at 50mW power consumption — 3x efficiency improvement over comparable OLED panels. The inorganic LED structure eliminated burn-in risks for always-on display applications.

Pixel pitch options range from P0.9 (indoor 4K close-viewing) to P16 (outdoor billboard), with common-cathode driver ICs reducing power consumption by 30% compared to traditional common-anode designs.

Front-access magnetic modules and tool-less rear-service panels enable <5-minute module replacement without dismantling the entire display wall, minimizing downtime for digital-signage networks. EMC compliance per EN 55032 Class B ensures no interference with adjacent wireless communications (Wi-Fi, 5G, RFID) in retail and corporate lobby installations. IP65 front / IP54 rear ratings for outdoor displays, with conformal-coated PCBs (acrylic-urethane) preventing moisture ingress in humid tropical climates; operating temperature -20°C to +60°C. CE, FCC, and RoHS III certified; ETL/cETL listed for North American installations; CCC mandatory certification for China domestic market access.
