No.1 Application Scenarios: Comprehensive Upgrade of Large-Size Glass for Intelligent Cockpits
With the rapid adoption of intelligent cockpits, in-vehicle displays and glass components are becoming increasingly larger and more integrated, including:
CMS / Smart Rearview Mirrors, Central Control Panels, Touch Display Glass Cover Lenses
These components are required not only to deliver high-definition visual performance and responsive touch interaction, but also to provide optical and durability functions such as anti-glare, scratch resistance, and anti-fingerprint performance. As a result, significantly higher requirements are imposed on optical coating processes and equipment capabilities.
No.2. Market Challenges: Coating Uniformity Issues Driven by Increasing Substrate Size
1. Enlarged Substrates Expose Uniformity Limitations
Conventional coating systems struggle to achieve uniform film thickness over large-area glass substrates. Thickness deviations between the center and edges often lead to non-uniform brightness, contrast, and color performance across the display surface, directly impacting overall visual quality and user experience.
2. Limited Throughput, Poor Compatibility with Automated Lines
Traditional batch-type coating equipment typically involves frequent loading, unloading, and intermediate handling steps, resulting in long cycle times per substrate. This makes it difficult to seamlessly integrate with robotic handling systems and fully automated production lines.
3. Complex Multilayer Stacks, Difficulties in Stable Mass Production
Intelligent cockpit glass often requires multi-layer functional optical stacks, placing strict demands on film thickness control, chromatic consistency, and batch-to-batch repeatability. Conventional processes face challenges in maintaining long-term stability and yield when producing complex multilayer coatings at scale.
