2025 Focus on In-Vehicle Display Field HUD Development: K&D Technology Breaks Through with Technological Innovation

In 2024, the delivery volume of passenger cars in China equipped with HUD as a standard feature reached 3.56 million units, a year-on-year increase of over 55%. The penetration rate increased from 11% in 2023 to 16% in 2024, with the highest monthly penetration rate exceeding 17.4%. This data indicates that HUD technology has crossed the critical chasm in the theory of innovation diffusion, moving from early adopters to the early majority market, with exponential growth expected in the future. The HUD market is showing a dual-driven pattern of "high-end leading, mid-end popularization." Models priced below 300,000 RMB have become the main growth point for HUD penetration, accounting for nearly 70%.

In terms of technical routes, the market has mainly formed three HUD solutions: C-HUD (Combiner), W-HUD (Windshield), and AR-HUD (Augmented Reality). Among them, W-HUD, with its larger projection area and better user experience, occupies more than 70% of the market share. AR-HUD is growing rapidly, accounting for nearly 25% in 2024, becoming a key element in the differentiated competition of smart cars. Virtual panoramic display technology, led by brands like BMW and Xiaomi, is defined as the next generation of in-vehicle display innovation.

Technical Dilemmas of HUD PGU

Despite the rapid growth of HUD, the industry is still constrained by multiple technical bottlenecks, making large-scale popularization difficult. The primary issue is the contradiction between brightness and environmental adaptability: traditional TFT solutions have low light source utilization, with backlight brightness generally below 100,000 nits, making it easy for the display content to be "drowned out" in strong sunlight. Forcibly increasing brightness leads to soaring power consumption and overheating component issues. More troublesome is the risk of sunlight backflow—environmental light converges along the optical path back to the core image generation unit (PGU), easily causing component damage due to high temperature, becoming the "Achilles' heel" for outdoor use.

K&D Technology's Technical Breakthrough

Facing the common industry challenges, K&D Technology innovatively appliedMini-LED backlight technology to the HUD PGU field, bringing a breakthrough solution.

Compared to traditionalTFT solutions, Mini-LED backlight brightness can reach 1.2 to 2 million nits, significantly improving image brightness. High brightness also brings a substantial improvement in resolution and perfectly solves the contrast problem.

K&D Technology's PGU solution also has the advantages of low temperature rise and low power consumption, with clear comprehensive advantages compared to laser DLP technology.

At theIAA in Munich, Germany, K&D Technology's HUD PGU product was showcased, attracting numerous HUD field experts and scholarsbecause of its "ultra-high brightness, ultra-high contrast, low temperature rise, low power consumption" advantages. Both parties engaged in in-depth exchanges, sparking high expectations for future cooperation.

HUD PGU Reshapes the Driving Interaction Experience

Technical breakthroughs have brought revolutionary changes to real driving scenarios. K&D Technology's HUD PGU technology can achieve AR lane-level guidance, dynamically marking the driving trajectory at complex intersections in real-time through a dynamic light blanket.

At roundabouts and ramps, arrows are directly "laid" on the real road surface, providing intuitive navigation guidance for drivers.

Multi-scenario interaction is another highlight. By integrating with intelligent driving systems, K&D Technology's HUD can project pedestrian positions or obstacle alerts during automatic parking and blind spot warning. Especially in adverse weather conditions such as rain and fog, this functionality significantly enhances driving safety.

With more car companies following AR-HUD configuration, the PGU market is about to enter an explosive period. According to consulting firm Omdia's forecast, by 2027, global shipments of in-vehicle AR-HUD will exceed 5 million units, and PGU, as its core component, is expected to see a market size breakthrough of 5 billion RMB.

Cars are no longer just a means of transportation but have become a mobile space carrying more life and entertainment functions. In this trend,the innovation in PGU technology will no longer be limited to safety displays but will move towards a more immersive, smarter, and more humanized interaction experience.
