Abstract: Embodiments of a curved display assembly are disclosed. The assembly includes a glass sheet having first and second major surfaces. The second major surface defines a first curvature of the glass sheet, and the first curvature has a bend axis. The assembly also includes a curved display having a second thickness between first and second display surfaces. The display has a display region and two overhanging edges adjacent to the display region and parallel to the bend axis. A first adhesive bonds the second display surface to the second major surface in the display region. A second adhesive is disposed between each of the two overhanging edges and the second major surface. The second adhesive has a higher elastic modulus than the first adhesive. The overhanging edges each extend a distance outside of the display area that is at least three times the second thickness of the curved display.

Abstract: The embodiments of the present application disclose an organic light emitting display panel and a manufacturing method thereof. The organic light emitting display panel includes an organic light emitting diode layer and a metal nanoparticle layer. The metal nanoparticle layer is disposed on a side of the organic light emitting diode layer in contact with external environment, wherein metal nanoparticles of the metal nanoparticle layer can use their own surface plasmon resonance absorption effect to absorb ultraviolet rays emitted from external environment to the organic light emitting diode layer, thereby preventing ultraviolet rays from irradiating the organic light emitting diode layer.
