Zusammenfassung: | The utility model discloses an organic light-emitting diode illumination screen, and the screen comprises a substrate, a plurality of organic light-emitting diodes disposed on the substrate, and packaging layers which are used for packaging the organic light-emitting diodes. Each organic light-emitting diode comprises a first electrode, a second electrode, and an organic functional layer disposed between the first and second electrodes. The organic functional layers are arranged independently. The packaging layers are respectively used for the packaging of one or more organic light-emitting diodes, wherein the number of the packaging layers is not less than two. The arrangement of an independent light-emitting zone and an independent packaging film at the same time protects the screen from being damaged completely because of defective points of the organic light-emitting diodes or poor packaging effect, thereby prolonging the service life of the screen. |
