Since the beginning of this year, various regions have introduced incentive policies such as tax reductions and government subsidies to encourage the purchase of new energy vehicles (NEVs). The market is particularly vibrant during the Mid-Autumn Festival and National Day holidays, as automakers boost sales with promotional discounts. As a result, the NEV market is flourishing.
This booming automotive market is also driving growth in the demand for vehicle displays. According to CINNO Research, the rising trend of new energy vehicles and smart cockpits has led to a steady increase in demand for automotive display panels. Global shipments of automotive display panels are expected to reach 200 million units in 2023, and by 2030, that figure is projected to rise to 267 million units.
Accelerating Mini LED Backlighting Adoption in Vehicles
Among various technological solutions, Mini LED backlighting has emerged as a popular choice in the automotive display market due to its low power consumption, high contrast ratio, support for curved displays, and large-size capability. GGII forecasts that shipments of Mini LED backlit automotive displays will exceed 1 million units by 2025.
However, despite the growing popularity of Mini LED backlighting, there are still several challenges that need to be overcome to achieve mass production.
Challenge: High Technical Barriers
Mini LED backlighting is more complex than traditional LED technology in terms of design, packaging, driving, and control strategies. It requires a higher level of technical expertise and more investment in research and development. Additionally, ensuring consistent product quality and reducing defect rates remain obstacles to mass production.
Solution: Multi-Dimensional Efforts to Accelerate Mass Production
As a leader in the domestic LED industry, NationStar has extensive experience and robust R&D capabilities in Mini LED backlighting.
01. Technical Breakthroughs
NationStar‘s Component Division has prioritized the development of Mini POB and Mini COB technology platforms. By advancing white-light packaging structures, driving solutions, and material applications, the company continuously expands its Mini POB and Mini COB backlighting solutions to meet the demands of various terminal display products.
02. New Product Developments
In the automotive display sector, the Component Division has developed white-light and blue-light Mini POB and Mini COB solutions featuring high brightness, high contrast, and consistent quality. These products can achieve a 0mm OD value, making them suitable for ultra-thin display module designs. Some solutions have also passed AEC-Q102 automotive-grade testing.
03. Production Support
NationStar has built a new Mini COB production line with a cleanroom rated at 10,000-class, and some areas reaching 1,000-class. The production line features automation and intelligent processes, supported by a team of skilled technical professionals. This setup allows for rapid responses to new market demands and provides high-quality, customized Mini LED backlight solutions.
Challenge: High Production Costs
Cost is a critical factor in vehicle manufacturing, and the high production costs of Mini LED backlighting have impacted its price competitiveness in the automotive market.
Solution: Cost Control and Quality Enhancement to Break Price Barriers
Leveraging its advanced technological expertise and extensive market experience, NationStar’s Component Division has developed unique light source designs that allow light to be emitted across a wide viewing angle. This not only supports the thin and light design of display modules while delivering high image quality but also reduces the number of required LEDs, optimizing overall costs and enhancing the price competitiveness of Mini LED backlight products.
Continued Focus on Mini LED Backlighting
NationStar has a clear strategy for developing its Mini LED backlighting technology, focusing on continuous innovation and diversifying its solutions. The company aims to expand its presence across a range of applications, including automotive displays, televisions, monitors, and tablets. This year, NationStar’s Mini LED backlighting solutions for automotive displays have been showcased at major exhibitions, receiving high praise from attending customers.
