Abstract
The failure of display modules in cellular phones due to drop impact depends on the materials, stiffnesses and shapes of the phones. In the early development stage of cellular phones, the behavior of the display modules due to drop impact is tested using jigs where the display modules are installed. In this study, jigs of cellular phones for drop impact test of OLED modules were designed. The material, thickness and number and orientation of ribs were considered as design variables. Jigs were designed in a way that responses of modules due to drop impact were similar to those of modules in cellular phones. The maximum principal stresses at the upper glasses of modules were considered as responses, which were analyzed using a commercial software ABAQUS/Explicit. The drop impact analysis at the height of 1.5 meters showed that the responses of OLED module in the developed jig were in a good agreement with those in cellular phone.
