Embodiment Construction

[0048] Reference will now be made in detail to the preferred embodiments, examples of which are illustrated in the accompanying drawings.

[0049] In the OLED display device, since a crack may be generated in the encapsulation film at the edge in the folded region, the bent region, or the curled region, damage of the light emitting diode may occur.

[0050]That is, when the display device is folded, bent, or rolled, stress is concentrated in the packaging film at the edge in the folding area, bending area, or curling area, cracks may be generated in the packaging film, and moisture may penetrate through the cracks. The display area of ​​the display device.

[0051] Therefore, in the related art flexible OLED display device, the light emitting diode and / or the thin film transistor are damaged, resulting in a decrease in display quality and / or lifetime of the related art flexible OLED display device.

[0052] figure 2 is a schematic cross-sectional view of the flexible OLED d...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0074968 filed on May 28, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an organic light emitting diode (OLED) display device, and more particularly, to a flexible OLED display device capable of preventing damage to the light emitting diode. Background technique [0004] Various display devices for displaying images are currently in use. Flat panel display devices, such as liquid crystal display (LCD) devices, plasma display panels (PDP) and organic light emitting diode (OLED) display devices, are widely studied and used to replace cathode ray tube (CRT) display devices because flat panel display devices Excellent performance with thin profile and light weight. [0005] Among flat panel display devices, OLED display devices have been widely studied because th...
