Abstract

The embodiment of the invention discloses an OLED (Optical Light Emitting Device) illuminating device and a manufacture method thereof. The OLED illuminating device comprises a glass substrate, and a transparent anode, an organic functional layer and a metal cathode which are sequentially arranged on the glass substrate, wherein the transparent anode comprises a plurality of display unit electrodes which are mutually independent from each other and auxiliary metal electrodes connected with the display unit electrodes which are mutually independent from each other. The OLED illuminating device provided by the embodiment of the invention not only can solve the problem that the brightness of light emitted by the device is nonuniform, but also can reduce the device damage probability for the occurrence of short circuit points.

Description

Technical field: [0001] The invention relates to the technical field of lighting, and more specifically, to an OLED lighting device and a manufacturing method thereof. Background technique: [0002] With the global energy crisis and people's increasing attention to environmental protection, energy conservation and environmental protection have become the mainstream of society. As far as the lighting industry is concerned, the development of green lighting with high efficiency, long life, safety, environmental protection and stable performance has become a common goal of all countries in the world.
