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: 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: Embodiments relate to a method of forming an organic light emitting diode (OLED) display device. A first inorganic layer, a first organic layer, and a second inorganic layer are formed on pixel regions of an OLED display device. At least part of a first inorganic layer is formed using atomic layer deposition (ALD), such that the first inorganic layer completely covers particles generated on the OLED. Embodiments also relate to an OLED display device with pixel regions, each pixel region including an OLED, a bank layer across a boundary between adjacent pixel regions, and a first inorganic layer on at least a portion of the OLED and the bank layer. The first inorganic layer includes a first inorganic sub-layer and a second inorganic sub-layer.
