High-performance organic-inorganic hybrid plastic substrate for flexible displays and electronics

An inorganic-dominated silica/polyimide (PI) hybrid film has been successfully developed for the fabrication of flexible AMOLEDs. The existence of networks between silica particles in the PI matrix have been confirmed by 3-D tomography, respectively. The inorganic-organic hybrid film was achieved by roll-type processing with a variety of attractive properties, such as low coefficient of thermal expansion (CTE, 20 ppm/degrees C), high transmittance (within the wavelength range of 400-700 nm), excellent flexibility, and high Young's modulus. Additionally, a flexible color-filter, an AMEPD, and a flexible touch film were fabricated on hybrid film.
