Flat Panel Display
Precision Linear Guidance Applications
Schneeberger has deployed over 800 custom positioning systems for flat panel display (FPD) manufacturing and inspection, with some systems manufactured and assembled in Asia. Covering Gen 4 to Gen 12 panel sizes, applications include automated optical inspection (AOI), colour-filter printing, interferometry, and other critical processes.
Linear Guidance Challenges in Flat Panel Display Manufacturing
FPD manufacturing equipment must handle large-area substrates, maintain precision positioning during high-speed motion, and meet throughput requirements for mass production.
Large-Area Substrate Handling
FPD substrate sizes continue to grow from Gen 4 to Gen 12, requiring positioning systems that maintain accuracy and stability across extremely large travel ranges. Schneeberger custom systems are scalable up to Gen 12 panel sizes to meet various generation production line requirements.
Multi-Head Parallel Inspection
Large-area panel inspection requires multiple optical inspection heads operating simultaneously to increase throughput. Schneeberger custom gantry systems support 4 independent AOI heads operating in parallel on a single platform, significantly improving inspection efficiency.
High-Damping Base Material
FPD inspection and printing equipment requires high-damping base materials to suppress vibration. Schneeberger uses high-damping base materials as an alternative to traditional granite, maintaining vibration suppression performance while reducing costs.
Precision Printing Positioning
Colour-filter printing processes require precision XY positioning to ensure colour pattern alignment accuracy. Schneeberger custom systems provide large-travel precision XY positioning platforms for Gen 8 and other large-area substrate printing requirements.
