Journal ArticleDOI
Development of robust flexible OLED encapsulations using simulated estimations and experimental validations
Chang-Chun Lee,Yan-Shin Shih,Chih-Sheng Wu,Chia-Hao Tsai,Shu-Tang Yeh,Yi-Hao Peng,Kuang-Jung Chen +6 more
TL;DR: In this article, a robust methodology composed of a mechanical model of multi-thin film under bending loads and related stress simulations based on nonlinear finite element analysis (FEA) is proposed, and validated to be more reliable compared with related experimental data.
Journal ArticleDOI
Investigation of Optical and Flexible Characteristics for Organic-Based Cholesteric Liquid Crystal Display by Utilizing Bending and Torsion Loadings
TL;DR: In this paper, the authors introduced two important types of testing loads (i.e., entire reverse of bend and torsion with several cycles) to investigate the optical and flexible characteristics of film-type cholesteric liquid crystal displays (ChLCDs).
Journal ArticleDOI
Predictions and measurements of interfacial adhesion among encapsulated thin films of flexible devices
TL;DR: In this article, the authors employed the four-point bending test (4-PBT) to measure the interfacial strength of pressure-sensitive adhesive (PSA)/SiN passivation stacked thin films.
Proceedings ArticleDOI
Mechanical reliability enhancement of flexible packaging with OLED display under bending loading conditions
TL;DR: In this paper, a model of multi-layer under bending loadings and related stress simulations, based on finite element method (FEM), is proposed to analyze the stress/strain characteristic of flexible packaging with organic light-emitting diode (OLED) devices under various geometrical combinations of stacked thin films and plastic substrate.
Proceedings ArticleDOI
Packaging designs and flexural stress estimation for thin-film types of OLED devices
Chang-Chun Lee,Chih-Sheng Wu,Tzai-Liang Tzeng,Chia-Hao Tsai,Shu-Tang Yeh,Yi-Hao Peng,Kuang-Jung Chen +6 more
TL;DR: In this article, a nonlinear finite element analysis combined with the approach of full factorial design is performed to explore several concerned mechanical parameters within a whole structure and the results reveal that the thickness of PI_substrate is the most dominant to determine the position of neutral axis and the bending stress of indium tin oxide film, separately.
