Abstract

Due to the recent development of different types of flexible displays, the lamination process for bonding between the organic light-emitting diode (OLED) panel and the window cover has become more important. In this study, we studied the process technology that can be applied to various types of displays by applying the pattern lamination process method using optically clear resin(OCR) instead of the existing optically clear adhesive (OCA). The OCR pattern was optimized by adding dam pattern during the process, and the overflow was within 0.1 mm and the thickness deviation was within 10%. Using the optimized process method, OCR with various viscosities could be used to optimize the process.

摘要

由于近来不同类型的柔性显示器的发展，有机发光二极管（OLED）面板和窗盖之间的粘合工艺变得更加重要。在这项研究中，我们通过使用光学透明树脂（OCR）代替现有的光学透明粘合剂（OCA）的图案层压工艺方法，研究了可应用于各种类型显示器的工艺技术。OCR图案通过在过程中添加坝图案进行优化，溢流在0.1mm以内，厚度偏差在10%以内。使用优化的工艺方法，可以使用各种粘度的 OCR 来优化工艺。
