Embodiment Construction

[0033] At present, flexible packaging is a key process for flexible displays, which directly affects the defective rate and reliability of flexible displays. Such as figure 1 and figure 2 As shown, in the flexible package, an encapsulation film 03 covering the display device 02 is provided on the base substrate 01. The encapsulation film 03 is generally composed of three layers, namely the first inorganic film 031, the organic film 032 and the second inorganic film 033; , the first inorganic film 031 and the second inorganic film 033 have a certain hardness, which can effectively prevent water and oxygen from entering the display device 02, so as to prevent the failure of the OLED device, but the thickness of the inorganic film is relatively thin, less than 1 μm, so it cannot wrap the tiny Particles will cause packaging failure; the thickness of the organic film 032 is about 6 μm-10 μm, which can cover and wrap some fine particles, and is more flexible, so as to improve the ...

Abstract

The invention discloses an organic electroluminescent display panel, A manufacture method and a display device thereof, At least one boundary bar is provide in that peripheral region of the substrate,A demarcation bar surrounds a plurality of display devices disposed in a display region of a substrate and has a closed annular structure, the inorganic film can be deposited without using a mask when forming the encapsulation film, An inorganic film is directly deposited on the whole surface of the substrate, and a boundary column with a thickness greater than the sum of the thicknesses of the inorganic films is utilized, so that a part of the inorganic film covered on the boundary column is in a disconnected state from other parts, thereby avoiding a shadow region with uneven film thicknessand facilitating the design of a narrow frame for packaging. Moreover, due to the existence of the boundary bar made of organic matter, when the crack propagates from the edge of the display panel tothe middle, the boundary bar can stop the crack propagates to the middle, and the crack does not propagate from the inorganic film broken at the boundary bar to the middle, which effectively protectsthe device from the risk of failure due to the influence of water and oxygen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic electroluminescence display panel, a manufacturing method thereof and a display device. Background technique [0002] With the advancement of display technology, more and more active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, AMOLED) display panels have entered the market, compared with traditional transistor liquid crystal display panels (Thin Film Transistor Liquid Crystal Display, TFT LCD) It has the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. At present, it has gradually replaced traditional LCD displays in the display fields of mobile phones, PDAs, and digital cameras. [0003] At present, the packaging of OLED display panels can adopt flexible packaging to realize flexible display. In flexible packaging, it is necessary to use Mask when de...
