Zusammenfassung:This paper presents a color characterization model based on a simple classification followed by a polynomial regression. By applying a three‐step optimization flow to cluster center, polynomial terms and training data, the performance is significantly improved. The proposed model has been tested among 9 latest mobile OLED panels, and the average error of all testing panels are less than 0.44 in CIEDE2000 with only 125 training data.
