Strength Innovation of In-Vehicle Display Supplier: The Application of Air Imaging to Light Field Screens by K&D Technology

The global automotive cockpit is experiencing a fundamental shift from a "mechanical space" to a "digital living space." According to research by Guohai Securities, the smart cockpit market is rapidly growing, expected to increase from 57.9 billion yuan in 2025 to 117.1 billion yuan in 2030, with an annual compound growth rate of about 15%.

Behind the market growth is the fierce competition of technical paths. Analysis by Sigmaintell Consulting points out that MiniLED and OLED have formed a "competitive cooperation relationship" in the field of vehicle displays, competing while iterating in the mid-to-high-end markets. The traditional "multi-screen stacking" logic is facing bottlenecks: limited physical space, visual fatigue, and fragmented interaction have become common issues in the industry.

The market calls for solutions that can break physical boundaries and reconstruct the human-car relationship.

K&D Technology's Innovation Matrix: Three Core Products that Break Screen Boundaries

To stand out in the vehicle display field, K&D Technology has not joined the internal competition of screen parameters but has focused on a series of innovative products as core, reshaping the value experience in the vehicle display field from three dimensions: aesthetics, safety, and health.

Innovative Product 1: Display Invisibility—Intelligent Wood Grain Hidden Display, Reconstructing Interior Aesthetics and Functional Boundaries

Core Concept: Screens should not be "visual black holes" in the cabin, but should become part of the high-end interior itself.

Technical Breakdown: The breakthrough of this technology lies in the precise integration of semi-transparent silk-screen printing and Mini LED local dimming technology. By high-precision silk-screen printing, real wood grain or leather texture is printed on the cover plate, achieving perfect integration with the interior when the screen is off. When lit, the high-partition Mini LED backlight system precisely activates the display icon area, while the rest maintains a decorative texture, solving the problems of "light leakage" and "halo" in traditional backlighting in dark scenes, achieving dynamic, pure coexistence of "decorative area" and "display area".

Pain Points and Value: It fundamentally resolves the contradiction between large screens and the cabin's overall design aesthetics, elevating the automotive interior from merely "decoration" to a composite functional unit of "decoration + intelligent interaction". For car companies seeking differentiated luxury and integrated aesthetic design, this provides a new dimension beyond screen parameter competition.

Innovative Product 2: Interaction Without Medium—Medium-Free Air Imaging, Defining New Safety Standards for Spatial Interaction

Core Concept: True safe interaction should allow the driver's line of sight to remain on the road.

Technical Breakdown: Based on the principles of negative refraction flat lens and light field reconstruction, K&D Technology's "air imaging" technology can form a stable, interactive real image in the air without any physical medium. It is supported by an ultra-high brightness (up to million-nit level) Mini LED backlight module and a precise optical system, ensuring clear imaging in complex vehicle light environments. This technology has "five protections" (fingerprint-proof, infection-proof, anti-static, contactless, medium-free), making it naturally suitable for the vehicle environment.

Pain Points and Value: It directly tackles the core pain point of driving safety—the driver's line of sight deviation caused by operating physical screens. Floating information in the air such as navigation and speed, combined with gesture or voice control, achieves "eyes on the road" interaction, turning safety from passive protection to proactive interaction design, providing a key interaction safety solution for advanced intelligent driving cockpits.

Innovative Product 3: Visual Health—Holographic Light Field Screen, Tackling Industry Challenges of Visual Fatigue and Motion Sickness

Core Concept: Targeted relief of visual fatigue and motion sickness.

Technical Breakdown: This technology, through a unique multi-stage optical path reflection system, simulates and extends the visual focus, allowing for an equivalent far-view distance of over 3 meters on small physical screens like headrests. This is consistent with the natural state of the human eye viewing distant objects, allowing the eye's ciliary muscles to relax. Meanwhile, the precise depth perception provided by Mini LED further enhances visual comfort.

Pain Points and Value: During long trips, passengers staring at close screens is the main cause of visual fatigue and motion sickness (due to conflicts between visual and vestibular signals). The light field screen pushes the "screen" away through optical principles, effectively alleviating these symptoms, upgrading rear-seat entertainment from "functional configuration" to "health care experience". It establishes a technical moat centered on "health" for K&D Technology in segments such as family cars and high-end commercial vehicles.

The Full Chain Supply Advantage and Customization Strength under the Background of Domestic Substitution

In the context of increasing importance of supply chain stability, K&D Technology's core competitiveness as a local supplier stems from its unique "central enterprise strength + private enterprise vitality" dual advantage and deep vertical integration capability.

K&D Technology, through its parent company China National Building Material Group's over seventy years of accumulation in the new materials field, has successfully established a complete industrial chain closed loop "from sand to screen", achieving an entire chain layout from high-purity quartz sand → glass substrate → panel thinning → glass cover plate → 3A cover plate → touch → touch display → touch display integration.

This full industrial chain "independent controllable" model not only ensures the stable supply and cost optimization of key raw materials but also shortens the customization response cycle compared to the industry average level, significantly enhancing supply chain resilience.

In addition, K&D Technology, through a parameterized, modular agile development platform, can conduct deep joint development ( JDM) with automotive customers. Its intelligent manufacturing capability has also been nationally recognized, with its Bengbu factory selected as a "National Excellent Smart Factory" for the year 2025. This comprehensive capability, integrating R&D innovation, intelligent manufacturing, and industrial chain ecosystem, enables K&D Technology to quickly respond to the high reliability and personalization market demands of in-vehicle displays, elevating from a pure hardware supplier to a strategic partner for automotive companies in the smart cockpit field.

K&D Technology's exploration shows that the future competition of intelligent cockpit displays is essentially a comprehensive competition of optical, material, interaction, and supply chain integration capabilities. From "making the screen disappear" to "making interaction float", and then to "making vision relax", each step precisely addresses the key pain points of smart cockpit evolution. Through the full industrial chain advantage to ensure "stable delivery" and "cost competitiveness", K&D Technology is building a multi-dimensional competitiveness model that is difficult to simply replicate.
