Patent ID: 10818876

Abstract:
The present disclosure relates to an organic light-emitting diode (OLED) display panel, including: a substrate, an OLED array layer configured on the substrate, a thin film packaging layer configured on the substrate and the OLED array layer, and a light extraction layer configured within the thin film packaging layer. The OLED array layer includes a plurality of OLED components arranged in matrix. The thin film packaging layer includes at least two inorganic barrier layers and at least one organic buffer layer. One side of the inorganic barrier layer facing away the substrate includes a plurality of pixel grooves corresponding to tops of each of the OLED components. The light extraction layer is configured within the pixel grooves, and the light extraction layer is covered by a flattening film configured to seal the light extraction layer within the pixel grooves, so as to flatten a surface of the inorganic barrier layer.
