Detection of defects on displays based on microscopic and optical coherence tomography examination

Abstract

[Excerpt] Introduction The use of displays in control car panels, smartphones, notebooks and LCD TVs has increased in the last decade. The large-scale manufacturing of new products emphasizes the need for fault detection at an early stage in the assembly process to detect the presence of scratches and particles. Therefore, fast, reliable and efficient displays inspection equipment is essential in order to reduce productionline stoppages, increase productivity and ensure the product reliability.[...]
