  • Organic light emitting diode display and manufacturing method thereof
    Patent number: 9130192
    Abstract: A organic light emitting diode display including an organic light emitting display panel displaying an image, and a lower passivation film attached to a bottom of the organic light emitting panel and including a polymer resin and an antistatic agent, wherein the lower passivation film includes a plurality of stress adjustment patterns disposed to be adjacent to each other wherein decreasing the bending interval between the bending stress adjustment patterns formed at the lower passivation film processed with the antistatic agent and attached at the position corresponding to the bending portion of the organic light emitting panel, thereby selectively minimizes the stress of the bending portion of the organic light emitting panel, therefore, asymmetry of strains of the bending portions of the organic light emitting display panel can be prevented to remove a picture abnormality, and static electricity may be prevented.
