Abstract
This paper describes the development of a cost effective and reliable spacer inspection system for AC-plasma display panels. The system generates three dimensional profiles of spacers using a light-section microscope in conjunction with a PC-based vision system. Structured lighting is used in the light section microscope to provide a measure of spacer height. The system provides an economical way for 100% inspection of all spacers to improve display panel quality and yield
