In August, the Ministry of Industry and Information Technology, along with the National Radio and Television Administration, released a notification listing 104 exemplary applications for ultra-high-definition (UHD) video. This initiative aims to enhance the industry ecosystem and promote the large-scale implementation of UHD technology. At the same time, China’s national broadcaster and 25 provincial-level channels have largely shifted to high-definition (HD) broadcasting, with 73% of local city channels following suit. Last year, the country also launched its first 8K IPTV channel. These policy incentives and technological advancements are driving rapid growth across the entire UHD video industry, bringing the era of ultra-HD even closer.
As the UHD video market accelerates, Mini LED backlighting has emerged as a key technology for superior display performance. With its remarkable brightness, contrast, and wide color gamut, Mini LED technology is becoming the backbone of ultra-HD displays. Nationstar, a leader in China’s LED packaging sector, is strategically positioning itself at the forefront of this market. The company’s Component Division is actively expanding its Mini LED backlighting operations, overcoming technical challenges, improving product quality, and reducing costs to facilitate the wider adoption of ultra-HD displays.
Backlighting Brilliance: Mini LED Drives Ultra-HD Displays Across Multiple Fields
Within the Mini LED backlighting sector, Nationstar’s Component Division customizes its strategies to meet diverse market needs, leveraging its core strengths. It focuses on advancing Mini LED packaging technologies to enhance both performance and quality. The division promotes dual pathways with Mini POB (Package on Board) and Mini COB (Chip on Board) technologies, each excelling in delivering ultra-HD displays across various applications.
Mini POB Technology
- Applications: 55-inch, 65-inch, and 75-inch TVs, 27-inch, 31.5-inch, and 34-inch monitors, and automotive displays. Custom technical solutions are available for each.
- Key Features: Thin and light display modules, high image quality, and cost-effectiveness.
- Driving Architecture: Options include “Separate Light and Drive,” “PM Integrated Light and Drive,” and “AM-Micro IC Integrated Light and Drive.”
Key Focus of Mini POB
For larger displays like TVs and monitors, where cost efficiency is crucial, Mini POB technology significantly reduces the number of LEDs required within a backlight module while maintaining high production yields. This reduction helps lower backlighting costs, providing a clear cost advantage. In the automotive display sector, Nationstar’s improved POB technology offers enhanced reliability, resistance to temperature and current, and wide-angle optical dimming, meeting automotive screen requirements. Some products have even passed automotive-grade certification.enhanced reliability, temperature and current resistance, and wide-angle optical dimming—all aligning with automotive screen requirements. Some products have even passed automotive-grade certification.
Mini COB Technology
- Applications: 75-inch TVs, 12.9-inch tablets, automotive displays, VR displays, with custom technical solutions available.
- Key Features: High brightness, uniformity, and reliability.
- Driving Architecture: Options include “PM Integrated Light and Drive” and “AM-Micro IC Integrated Light and Drive.”
Key Focus of Mini COB
With an optical distance (OD) of 0mm or more, Mini COB technology enables ultra-thin designs, albeit at a higher cost. To mitigate this, Nationstar’s Component Division optimizes light source costs to keep the final module price accessible to consumers. The division has also set up the industry’s most advanced COB production line, improving production yields and reducing costs.
Riding the 5G and 8K Visual Revolution
Amidst the surge of 5G technology and the 8K visual revolution, Nationstar is poised to increase its R&D investments, enhance technological innovation, and develop cutting-edge technologies to maintain its leadership in the Mini LED backlighting market.
