In recent years, with the acceleration of trends in automotive intelligence and electrification, consumer demands for in-car display technology have grown increasingly high. Traditional automotive displays mostly use LCD backlighting or Mini LED backlighting, but as technology continues to advance, Mini LED direct-display technology is emerging and gradually being adopted in the commercial vehicle sector. Recently, Jufei Optoelectronics collaborated with Changan Automobile to equip its new model Qiyuan E07 with the world’s first commercial mass-produced Mini COB Star-ring Smart Full-Color Interactive Screen. This screen utilizes Jufei Optoelectronics’ Mini LED direct-display technology, marking the company’s first application of this technology in commercial vehicles, a significant milestone for the LED display industry.
Mini LED Backlighting vs. Mini LED Direct Display Technology
1. Mini LED Backlighting Technology
Mini LED backlighting technology is currently one of the most widely used display technologies in automotive screens. This technology uses a large number of Mini LED chips placed behind the LCD panel to serve as the light source, providing higher brightness and more uniform display effects. Compared to traditional LED backlighting, Mini LED backlighting offers improved brightness and contrast, better meeting the demands of automotive displays.
However, despite the improvements in brightness and contrast, Mini LED backlighting still has limitations. Due to the characteristics of the LCD panel itself, it cannot achieve true black display, and contrast remains limited. Moreover, the backlighting technology may suffer from light leakage, which affects the display quality.
2. Mini LED Direct Display Technology
Mini LED direct-display technology is an entirely new display method that utilizes Mini LED chips directly as pixels, creating a self-emitting display. This technology offers significantly higher brightness and contrast, achieves true black displays, and boasts a longer lifespan and lower power consumption.

The advantages of Mini LED direct-display technology include:
- High brightness and contrast: Each pixel emits light independently, resulting in better brightness and contrast.
- True black display: It enables pixel-level true black display, improving contrast and overall display quality.
- Low power consumption and longer lifespan: The technology uses lower current to drive the LEDs, reducing power consumption and enhancing longevity.
Application and Significance of Mini LED Direct Display in Commercial Vehicles
As automotive intelligence and electrification continue to evolve, consumer demands for automotive display screens are becoming more sophisticated. Traditional Mini LED backlighting technology can no longer meet the increasing demand for display performance and quality. Mini LED direct-display technology can provide superior quality for central control screens, instrument clusters, entertainment displays, and more in commercial vehicles, displaying driving information, navigation, and entertainment content with higher precision, thereby driving the intelligent development of commercial vehicles and the broader industry chain.
Additionally, reports indicate that Li Auto‘s entire vehicle lineup and Geely’s LEVCTX5 model for the Asian Games will adopt Mini LED direct-display technology, bringing new display effects and performance improvements to in-car displays.
Mini LED direct-display technology provides higher brightness and contrast for clearer visuals, enhancing the driving experience and safety for commercial vehicle drivers. Displays with this technology also have a longer lifespan, reducing the frequency of replacements and repair costs, which lowers operational expenses and improves economic efficiency for fleet operators. Jufei Optoelectronics’ first use of Mini LED direct-display technology in commercial vehicles represents a significant innovation in automotive display technology, driving further technological progress in the entire industry.
Market Prospects and Challenges of Mini LED Direct Display Technology
With the rising consumer demand for smart cars and improved display performance, Mini LED direct-display technology holds vast potential for application in the automotive display market. As technology continues to advance and costs decrease, Mini LED direct-display technology is expected to gradually replace traditional Mini LED backlighting, becoming the mainstream technology for automotive displays. Furthermore, the technology’s applications extend beyond automotive displays to other fields like TVs, computer monitors, and virtual reality devices, with a promising market outlook.
However, despite its advantages, Mini LED direct-display technology faces several challenges in practical implementation.
Currently, the cost of Mini LED direct-display technology remains relatively high, limiting its widespread adoption in the automotive display sector. To lower costs, LED display manufacturers need to optimize production processes and supply chain management, enhancing production efficiency and reducing manufacturing costs.
The technology also involves multiple technical hurdles, such as mass transfer and driver circuit design. To overcome these challenges, companies must increase R&D investments and collaborate with universities and research institutions to foster technological breakthroughs. As more companies enter the Mini LED direct-display field, competition will intensify. To maintain a competitive edge, businesses need to continually improve product quality and service levels, focusing on brand development and market promotion.
Conclusion
The first application of Mini LED direct-display technology in commercial vehicles marks another revolution in automotive display technology. This move not only enhances display quality and lifespan but also drives innovation and market development. As technology progresses and costs decrease, Mini LED direct-display technology is expected to gradually replace traditional Mini LED backlighting, becoming the dominant technology in automotive displays. This will inspire more LED display companies to invest in R&D and market expansion, accelerating the adoption of Mini LED direct-display technology in automotive displays and providing consumers with better display products and services.
