Abstract: A flexible organic light emitting display (OLED) device includes a flexible substrate having a display area, a non-display area at a periphery of the display area and a folding region; at least one organic emitting diode on the flexible substrate in the display area; an encapsulation film covering the organic emitting diode; and a dam on the flexible substrate. The dam laterally surrounds the display area and includes: a first dam in the folding region; and a second dam outside the folding region, wherein the average thickness of the first dam is smaller than the average thickness of the second dam.

Abstract: A flexible organic light emitting display (OLED) device includes an organic emitting diode on a flexible substrate, an encapsulation film covering the organic emitting diode and including a first inorganic layer and an organic layer. The first inorganic layer is formed of a first material, and at least a portion of the first inorganic layer includes a dopant that increases the surface energy of the doped material compared to that of non-doped material.

Abstract: Embodiments relate to a flexible organic light emitting diode (OLED) display device and a method for manufacturing the flexible OLED display device. The display device includes a multi-layered encapsulation film coving pixel regions of the display device, and a metal layer on or within at least a portion of the encapsulation film, the portion in a bending region of the flexible substrate. The multi-layered encapsulation film includes at least a first inorganic layer, an organic layer, and a second inorganic layer. The metal layer is formed in the bending region such that the stress generated in the encapsulation film by folding, bending, or rolling operations in the bending region is reduced by the metal layer. The metal layer prevents generation of cracks in the encapsulation film and thus, prevents moisture penetration into the display area of the display device.
Abstract translation: 实施例涉及柔性有机发光二极管（OLED）显示装置和制造柔性OLED显示装置的方法。 所述显示装置包括所述显示装置的多层封装胶片的像素区域，以及位于所述柔性基板的弯曲区域中的所述封装膜的至少一部分上或其中的金属层。 多层封装膜至少包括第一无机层，有机层和第二无机层。 金属层形成在弯曲区域中，使得通过在弯曲区域中的折叠，弯曲或滚动操作在封装膜中产生的应力由金属层降低。 金属层防止在封装膜中产生裂缝，从而防止湿气渗入显示装置的显示区域。
