Forum scene
Driven by the wave of automotive intelligence, intelligent cockpit display technology is undergoing a comprehensive revolution. The trends towards larger screens and ultra-high definition are significant, with central control screens of 15 inches and above becoming mainstream, and 4K and 8K technologies becoming increasingly widespread. With the deep integration of multi-screen interaction and intelligent connectivity, automakers are increasingly demanding personalized and customized in-vehicle screens.
Product Solutions: Smart Cockpit Full-Scenario Product Layout <br /> Leveraging its advanced Mini LED technology and large-scale mass production capabilities, Hongli Display is gradually achieving full-scenario display product coverage for smart cockpits, including HUD head-up displays, digital instrument clusters, central information displays, electronic rearview mirror displays, rear-seat entertainment screens, A-pillar displays, and roof-mounted screens, providing a comprehensive range of solutions.
In 2024, Hongli Display successfully obtained supplier codes from several mainstream automakers and completed mass production and delivery of automotive backlight modules. To date, the company has successfully mass-produced automotive display projects including GAC's 15.6-inch central control display, JK's 13.02-inch digital instrument panel, and Jeep's 12.3-inch digital instrument and central control display screens.
Technological Advantages: Dual Process Routes + Full-Size Coverage <br /> Hongli Display has established a unique dual process route (POB and COB) and full-size product coverage in the Mini LED backlight field. The company's Mini LED backlight products possess the following advantages: High local dimming and high contrast: Supports HDR display for more detailed image layers; High cost-effectiveness: Optimizes costs through microstructure design and dual process routes (POB & COB); Full-scene coverage: Meets diverse needs from VR and automotive to TV.
The company employs a dual-technology strategy (Mini LED backlighting and traditional backlighting) in automotive backlighting to address diverse market demands. The first is automotive Mini LED backlighting: based on the R&D, production, and sales of Mini LED backlight boards, the company's automotive Mini LED backlight products have significant technological and cost advantages. The second is automotive traditional backlighting: the technology is mature, with multiple 12.3-inch, 14.6-inch, and 15.6-inch projects already in mass production. Furthermore, for the core component, the Light bar, Hongli Display possesses LED packaging capabilities and SMT assembly capabilities for light strips.
Innovative technologies
HUD (Head-Up Display) + Vehicle External Interaction Technology <br /> In terms of technological innovation, Hongli Zhihui is actively developing the HUD technology field, comprehensively advancing the development of its 11.98-inch P-HUD product. Simultaneously, it is increasing R&D investment in vehicle external interaction technology, promoting the innovative application of Mini LED direct-display technology in vehicle external display scenarios, and providing a richer human-vehicle interaction experience for future intelligent vehicles.
Looking ahead, Hongli Display will continue to deepen its expertise in Mini LED display technology, providing comprehensive support for direct-view products and backlighting products for VR, automotive, and TV applications. The company looks forward to collaborating with more industry partners to create a new future for intelligent driving visual experiences.
