| Abstract: | Abstract— A screen‐mottling inspection and analysis system for CRT manufacturing has been developed for in‐factory quality control. This system is capable of translating the implicit knowledge of mottling judgement by the human eye to a quantitative and explicit knowledge through a machine. Screen‐mottling judgement by the human eye has always been argumentative and subjective to personal sensitivity. With the successful development of a CRT‐screen‐mottling checker, an accurate and consistent reading of ±0.1 units on a scale that ranges from 1.0 to 3.0 can be achieved. This eliminates the fluctuations of human judgement. To the authors' knowledge, there are a few mottling analysis systems used in non‐display‐related industries which only capture and analyze flat reflective surfaces. These systems cannot be used for CRT displays because of the non‐uniform glass thickness and curvature of the glass. This newly developed CRT‐mottling checker system is probably one of the first checkers for the CRT industry. |
