P.149L: Late‐News Poster: Behavior of OLED Panel under 4 Points Bending Test

Four‐point‐bending (4PB) test is a common method to evaluate the strength of a panel. In this paper, we discussed the behavior of organic light emitted display (OLED) during bending. We found most of OLED panels show a unique fracture mode that fracture originates from the sealing material frit, which is different from the glue used in LCD panels. This study verified this phenomenon through experiment and simulation.
