The Effect of Various UV Curing Patterns of Optically Clear Acrylate Adhesive for Flexible Mobile Devices |
| 초록 |
Development of Optically Clear Adhesive(OCA) for flexible displays is required. OCA for flexible displays should exhibit high elongation and resilience for free expansion. Recovery force and elongation rate have trade-off relationships with each other. Correlation between curing pattern and recovery/elongation rate of OCA has been studied. The UV Patternization process was devised to demonstrate both excellent elongation rate and recovery properties which are inversely proportional to each other. The elongation rate was measured by the stress relaxation test and the recovery was measured by the strain recovery test. The results of this study suggest that the patterned OCA according to the degree of UV curing could be applied as OCA for flexible displays by expressing elongation in low-curing areas and recovery in high-curing areas. |
