66‐3: Effective Foldable AMOLED Structure with Bendability and Impact Resistance

Mayuko Sakamoto,

Noriko Watanabe,

Katsuyuki Suga

et al.

Abstract: We developed an optimized shock absorber structure for foldable OLED displays using FEA (finite element analysis) which includes thin OCA and metal film with slits. Our AMOLED prototype passed a 200k times in‐fold bending test with 1.5mm bending radius and a ball drop test of 100g from the height of 60cm.

Rollable display has a characteristic feature in assessing surface quality which is caused by a periodic supporter structure. In the presence of such periodic deformation, we suggest a method to quantify them and verified a correlation with human recognition by performing a cognitive experiment. Our method can be utilized in assessing the surface quality including any linear and periodic component.
