UV-cured OCAs are being widely used and getting more importance in the display industry. Especially, with the commercialization of the foldable display, the rheological properties of the OCAs which were inserted among functional films in a foldable display module are becoming more important. The properties of OCAs depends on the OCA composition as well as UV curing condition. In this study, we investigated the effects of UV curing process (i.e, UV intensity and irradiation time) and OCA composition on the rheological properties of OCAs. We found that OCA’s rheological properties(e.g., storage modulus, elongational viscosity, etc.) was changed as the UV Intensity and the content of IBOA(Isobornyl acrylate). |
