Problems solved by technology

[0004] Usually, in order to prolong the service life of OLED device 11, generally can add desiccant 15 in OLED sealing cavity, as figure 1 As shown, but in practice, the inventors have found that the desiccant can only eliminate water vapor, and oxygen will also age the OLED device 11, that is, the addition of the desiccant cannot eliminate the residual oxygen in the closed cavity or the oxygen infiltrated from the outside, and still cannot improve the OLED. Aging problem of device 11

Abstract

The embodiment of the invention discloses an organic light-emitting diode packaging structure and a display device. The packaging structure comprises an organic light-emitting diode substrate and a packaging substrate, an organic light-emitting diode device is arranged on the surface of the organic light-emitting diode substrate, an active metal film layer used for absorbing oxygen inside the packaging structure is arranged on the surface of the packaging substrate, the organic light-emitting diode substrate and the edge of the packaging substrate are fixed in a bonding mode through sealing adhesive so that a sealed cavity can be formed, and the organic light-emitting diode device and the active metal film layer are located in the sealed cavity. According to the organic light-emitting diode packaging structure and the display device, the active metal film layer absorbs residual oxygen in the sealed cavity or oxygen which seeps in from the outside, the requirement of the organic light-emitting diode device for oxygen permeability can be met, the ageing problem of an organic light-emitting diode can be solved to some extent, and the service life of the organic light-emitting diode device and the service life of the display device can be prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of manufacturing liquid crystal display panels, in particular to an organic light emitting diode packaging structure and a display device. 【Background technique】 [0002] Organic Light-Emitting Diode OLED (Organic Light-Emitting Diode) devices have become a highly competitive device due to its advantages such as all-solid-state structure, high brightness, full viewing angle, fast response speed, wide operating temperature range, and flexible display. The next-generation display technology with great strength and development prospects, and OLED displays have also become a new generation of displays. [0003] The OLED device 11 is formed by fabricating an organic thin film on an OLED substrate 12, wherein the organic thin film is wrapped between a cathode and an anode metal, and when a voltage is applied to the two electrodes, the organic thin film will emit light. Since the organic film is very sensitive t...
