In this work, a stretchable display based on LTPS AMOLED technology was designed. Our stretchable display, developed with a stretchable substrate with transitional area based on H-type kirigami pattern design, can withstand a 10% stretch ratio. The result show that the stretch ratio of substrate with transitional area is 25% higher than the substrate without transitional area since the concentrated stress was slow-released in the transitional area. Also, a more uniform bridge area layer structure and VDD signal was designed to ensure the stress and display homogeneity respectively. A TFE Dam was designed in each island to prevent the flowing organic encapsulation material.
We here demonstrated that a 200 PPI stretchable display can be deformed in an oval shape with radius of 50/90 mm and height of 3 mm. Besides, the relationship between the critical crack strain and modulus of different stretchable designs was verified. Based on the above research, the better module stacking for in‐plane and spherical stretching tests was further studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
