Quality Assessment Model for Processing Organic Light-Emitting Diode Displays

Recent developments in the manufacturing of organic light-emitting diode (OLED) displays have resulted in devices featuring an expanded color gamut, self-luminosity, increased resolution, reduced power consumption, and lighter weight. These advantages have led to the extensive application of OLEDs in high-end portable consumer electronics. As a result, the functionality and quality requirements of OLED displays are becoming increasingly important. This study employed a process capability index C _pk in the development of an innovative, integrated assessment model for critical-to-quality processes involved in the production of OLED displays. This approach considers process capability associated with three quality characteristics: nominal-the-best, the-smaller- the-better, and the-larger-the-better. The proposed model is capable of determining whether the processing of OLED displays fulfills a desired standard of quality, thereby enabling OLED manufacturers to increase production quality and enhance competitiveness.
