55.3: Invited Paper: Development and Manufacture for Free Form Mobile Phone Screen.

When Apple Inc. pushed out their "bang panel"(notch screen) in 2017, many display manufacture companies set out to develop free form full screen of mobile phone. In order to seize the market quickly, Shanghai AVIC Photoelectron Co., Ltd (AVIC for short) developed and manufactured the panel only in three more months. This paper introduced how we realized rapid production of free form full screen and what problems we had solved. We discussed free form cutting not only by CNC (computer numerical control) grind but also by laser cutting. We also discussed free form sealant coating. Line open in Fanout Zone at CNC grind process was analyzed and solved. At last, a special "black blob" of free form screen from customer complaint was investigated and solved. [ABSTRACT FROM AUTHOR]
