  • Organic light emitting diode display package with sealant and adhesive reinforcing member
    Patent number: 9293729
    Abstract: An organic light emitting diode display may include a display substrate including an organic light emitting diode, a sealing member facing the display substrate to cover the organic light emitting diode, a sealant positioned between the display substrate and the sealing member and bonding the display substrate and the sealing member, and a reinforcing member positioned at an outer surface of the sealant and a space between the display substrate and the sealing member, in which shear stress and hardness of the reinforcing member are a function of a sum of thicknesses of the display substrate and the sealing member.

  • Method for manufacturing flexible display device
    Patent number: 9276047
    Abstract: A method for manufacturing a flexible display device includes forming a separation layer on a carrier substrate, laminating a flexible substrate having an area that is larger than an area of the separation layer, to the separation layer; forming a dummy pattern on and along an edge of the flexible substrate; exposing a portion of the separation layer by removing a portion of the flexible substrate at a side of the flexible substrate; and separating the separation layer and the flexible substrate from each other.

  • Manufacturing method for flexible display device
    Patent number: 9257679
    Abstract: A method of manufacturing a flexible display device, the method including depositing a separation layer on a supporting substrate; depositing a display panel on the separation layer; cutting the display panel to have a predetermined shape; cutting the supporting substrate and the separation layer to have a wider area than an area where the display panel, that is cut with the predetermined shape, contacts the supporting substrate and the separate layer; and separating the separate layer and the display panel from each other.
