Abstract

The invention discloses an OLED (organic light-emitting diode) lighting substrate and a manufacture method thereof. The OLED lightening substrate comprises a substrate, wherein a positive electrode, an organic functional layer and a negative electrode are sequentially arranged on the substrate; a resistance layer is arranged between the substrate and the positive electrode, and the resistance layer is divided into multiple block-shaped resistors; the positive electrode is divided into multiple sub positive electrodes, and each sub positive electrode is connected with a block-shaped resistor in series; and the multiple block-shaped resistors are connected together through interconnection lines. The OLED lighting substrate and the manufacture method thereof disclosed by the invention have the characteristics that: a series-connection resistance layer is arranged between a power supply and the positive electrode, thus a current limitation action is achieved; and a whole large-area positive electrode is divided into smaller-area sub positive electrodes, so that the intensity of the gathered current generated by the positive electrodes isolated by resistors is weakened, the current gathering effect is weakened and short-circuit probability of the negative and positive electrodes is reduced, thus the problems that the electrode is easy to burn out and the light emitting is nonuniform are solved.

Description

technical field [0001] The invention relates to a lighting substrate and a manufacturing method thereof, in particular to an OLED lighting substrate and a manufacturing method thereof. Background technique [0002] In recent years, various types of flat panel lighting devices that are light in weight and small in size have been developed. Among various types of flat-panel lighting devices, organic light-emitting diodes (OLEDs) usually have many advantages such as low energy consumption, planarization, and large size, and have become the focus of next-generation lighting devices. [0003] Figure 1A It is a schematic diagram of the pixel structure of an existing organic light-emitting diode lighting device. The existing OLED lighting device generally includes a substrate 1 and a back cover 2, wherein an anode 3 is deposited on the substrate 1, and a very thin multi-layer organic function is provided on the anode 3. layer 4, and a cathode 5 located on the organic functional l...
