FPD Panel Inspection: Lighting Strategies for Display Manufacturing This case note explains how LuxMV engineers approach machine vision lighting inspection when stable contrast, repeatable positioning, and reliable defect separation are required on an automated line. Inspection Challenge The inspection target presents practical production challenges: small defects, changing surface reflectivity, limited installation space, and the need to keep false rejects under control. A lighting design must make the defect easier for the camera to separate before algorithm tuning begins. Lighting Approach A robust LuxMV setup starts with sample testing. Engineers compare illumination angle, wavelength, diffusion, and controller timing while keeping the camera, lens, and part position stable. The final recipe is selected by measured contrast margin rather than by visual preference alone. Where This Method Fits Typical applications include automated defect detection, OCR or mark reading, contour measurement, reflective-surface inspection, and quality control for parts whose appearance changes with material, coating, color, or process conditions. LuxMV Engineering Notes For production use, document the selected light model, exposure time, gain, aperture, working distance, trigger timing, and any polarizer or diffuser used in the optical path. This makes the inspection easier to reproduce when part suppliers, surface finish, or line speed changes.

Frequently asked questions
Can this article determine a final lighting specification?
No. Use the article as engineering context, then validate the light, camera, lens, working distance, and production conditions with the actual inspection target.
How can I discuss a related inspection requirement?
Share the target material, required feature or defect, field of view, working distance, camera and lens details, and representative images or samples with the LuxMV team.
