一直以来,触摸液晶显示屏贴合工序被认为是业界最难控制的工序,其质量直接影响整屏性能,会引起贴合气泡、黄斑、Mura(专用词,指显示器亮度不均匀,造成各种痕迹的现象——编者注)以及焊点强度不足等各种质量缺陷。实践中,影响贴合质量的关键参数为涂布后的OCR膜厚,因而调整涂布设备各项工艺参数以达到OCR膜厚最优成为贴合工艺设计的主要工作。一、DOE概述DOE是Design of Experiment(试验
All along, touch the LCD screen laminating process is considered to be the most difficult process in the industry, its quality directly affects the entire screen performance, will cause fit bubble, macula, Mura (special words, refers to uneven display brightness, resulting in various Traces of the phenomenon - editor’s note) and the lack of strength of solder joints and other quality defects. In practice, the key parameter that affects the quality of fit is the OCR film thickness after coating. Therefore, adjusting the process parameters of the coating equipment to achieve the optimal film thickness of OCR becomes the main work of laminating process design. First, DOE Overview DOE is Design of Experiment (test
