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/°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.

An inorganic dominated silica/polyimide (PI) hybrid film has been successfully developed for the fabrication of flexible AM-OLED. The inorganic-organic hybrid film was achieved in roll type with a variety of attractive properties such as low coefficient of thermal expansion (CTE, 33 ppm/℃), high transmittance (within the wavelength range of 400 to 700 nm), excellent flexibility and high Yang's modulus.
