An organic light-emitting diode (OLED) lighting device includes a substrate, at least a conductive wire, an insulating layer, a first electrode layer, an organic light-emitting layer and a second electrode layer. The conductive wire is disposed on the substrate and has a top surface away from the substrate. The insulating layer is disposed on the substrate and has an upper surface away from the substrate. At least a part of the top surface of the conductive wire is exposed from the insulating layer. The first electrode layer is disposed to cover the upper surface of the insulating layer, and is electrically connected with the conductive wire. The organic light-emitting layer is disposed on the first electrode layer. The second electrode layer is disposed on the organic light-emitting layer. According to the OLED lighting device of the invention, since the first electrode layer, the organic light-emitting layer and the second electrode layer are disposed on the conductive wire and the insulating layer such that they extend continuously in parallel to each other, conventional problems of thickness uneven of the organic light-emitting layer and cracks occurred at a bent part of an electrode can be solved, and thus a light-emitting uniformity of the OLED lighting device can be increased. In addition, a method for manufacturing the OLED lighting device is provided.
Description
technical field [0001] The present invention relates to a lighting device, and in particular to an organic light emitting diode lighting device and a manufacturing method thereof. Background technique [0002] Organic light-emitting diodes have the advantages of self-luminescence, low power consumption, and high response rate, and have attracted widespread attention in the fields of display and lighting. Organic light-emitting diodes generate light by electrically exciting a light-emitting layer of fluorescent or phosphorescent organic compounds. [0003] Most of the existing organic light-emitting diode devices use conductive thin films as electrodes to transmit current to the light-emitting layer, which is easily limited by the resistance value and is difficult to transmit large currents, resulting in unavoidable power loss. Especially in the field of lighting, this problem will be more obvious. Therefore, in order to transmit a large current, an additional shunt electro...
