17‐3: Study on Rollable AMOLED Performance Improvement

By considering rollable AMOLED display and application, optical and mechanical performances are discussed and optimized solutions are introduced. Different COE designs for rollable AMOLED are compared in power consumption, L‐decay and reflection. A rollable AMOLED module structure is designed with the impact absorption layer of the hybrid cover. Based on finite element simulation and neutral layer theory, module stack is optimized, accumuled strain is eliminated. Rollable performance and impact resistance are balanced. A portable device with rollable AMOLED is developed. Its mechanical design for rollable display application is introduced.
