摘要： Embodiments of the present disclosure disclose a display panel and a fabricating method thereof. In the solution, on one hand, water-absorbing magnetic nanoparticles in a packaging layer are distributed along a direction perpendicular to the cover plate at a side far away from an OLED component, or distributed along an extension direction of the packaging layer at a periphery of a region in which the OLED component is located, thus reducing the damage to the OLED component of a display substrate. On the other hand, since the water-absorbing magnetic nanoparticles have magnetic property, the water-absorbing magnetic nanoparticles can be doped in the packaging layer material in a packaging and waterproofing process, and a magnetic field is applied to induce the magnetic nanoparticles to move to the side far away from the OLED component or to the periphery of the region in which the OLED component is located.

摘要： An organic electroluminescent device, a method for preparing an organic electroluminescent device, and a display panel are disclosed. The organic electroluminescent device comprises a conductive layer formed by transparent magnetic conductive particles which are mixed in the sealing layer and stacked on a surface of the first transparent electrode layer. The conductive layer increases the conductive performance while not increasing the thickness of the first transparent electrode layer, thereby avoiding decrease of the light transmittance caused by increase of the thickness of the first transparent electrode layer, and avoiding the problem of voltage drop due to poor conductivity of the first transparent electrode layer, so as to improve the display effect and use stability of the organic electroluminescent device.

Each group of films comprises three films, and an intermediate film in each group of films is an intermediate inorganic-organic hybrid layer. The packaged structure comprises at least one group of films; the at least one group of films encapsulates an OLED to be packaged. Each group of films comprises three films, and an intermediate film in each group of films is an intermediate inorganic-organic hybrid layer. The intermediate inorganic-organic hybrid layer is arranged as an intermediate film in each group of films, and connects an upper film and a lower film in each group of films, so that adhesion between the upper film and the lower film in each group of films is effectively improved, and stripping of the upper and lower films is avoided.
