Hybrid auxetic metamaterial platforms enabling multiscale isotropic expansion for distortion-free stretchable displays
Abstract Stretchable displays suffer image distortion due to transverse compression of substrates under uniaxial stretching. Although auxetic frameworks with negative Poisson’s ratios, which expand vertically during horizontal stretching, offer promising solutions, their void-rich structures are unsuitable for displays, requiring hybrid integration with continuous elastomeric substrates.
3D height-alternant island arrays for stretchable OLEDs with high active area ratio and maximum strain - Nature Communications
Abstract Stretchable optoelectronic devices are typically realized through a 2D integration of rigid components and elastic interconnectors to maintain device performance under stretching deformation. However, such configurations inevitably sacrifice the area ratio of active components to enhance the maximum interconnector strain.
Stretchable OLEDs based on a hidden active area for high fill factor and resolution compensation - Nature Communications
Abstract Stretchable organic light-emitting diodes (OLEDs) have emerged as promising optoelectronic devices with exceptional degree of freedom in form factors. However, stretching OLEDs often results in a reduction in the geometrical fill factor (FF), that is the ratio of an active area to the total area, thereby limiting their potential for a broad range of applications.
