P‐10.4: Study on the influence of composite structure on the strength performance of display module

With the increasing application and demand of flexible AOLED display modules in the global market, improving the strength performance of display modules has important guiding significance for the development of OLED technology. In this paper, the height of the falling ball is used as the test index of strength performance, and the influence of the composite structure on the strength of the falling ball is studied through the combination of composite structure with different thicknesses and materials. It is found that in the composite structure with the same thickness, using foam instead of PI structure can obtain better ball falling results. The falling result of silica gel material is better than that of foam material, and the overall thickness of silica gel is thinner.
