Embodiment 1

[0071] Such as Figure 2a-2dAs shown, the present invention discloses an organic light-emitting OLED panel, comprising: a substrate 10 ; and a plurality of adjacent light-emitting units located on the substrate 10 . In the figure, only two adjacent light emitting units are shown, that is, the first light emitting unit 11 and the second light emitting unit 22 , other light emitting units are not shown. The organic light-emitting OLED panel further includes a third electrode 31 located between adjacent light-emitting units (ie, the first light-emitting unit 11 and the second light-emitting unit 22 ). Of course, since only two adjacent light emitting units are shown in the figure, a third electrode may also be provided between the second light emitting unit and the adjacent light emitting unit (not shown in the figure). It also includes a connection wire M for connecting the first light emitting unit 11 and the second light emitting unit 22 .

Abstract

The invention discloses an organic light emitting diode panel and device which is simple in preparation method and low in cost, and a preparation, short-circuit detection and short-circuit reparation method of the organic light emitting diode panel. The OLED panel comprises two or more light emitting units and one or more third electrodes, wherein each third electrode comprises an edge comprising a first edge extending out of the bottom side of the third electrode, and second electrodes of the adjacent light emitting units are positioned on the same layer and are disconnected at the edges of the third electrodes. Due to the fact that the light emitting units in the organic light emitting diode panel are connected in series, uniformity of integral brightness is ensured. The preparation method is simple and feasible. An ordinary open mask is adopted during preparation of the second electrodes, yield during technological process is ensured, cost is low, good operability is achieved, production cost is reduced, and production efficiency is increased.

Description

technical field [0001] The invention relates to the field of OLED (Organic Light-Emitting Diode) lighting, in particular to an organic light-emitting panel and an organic light-emitting device, as well as a method for preparing the organic light-emitting panel, a short-circuit detection method, and a short-circuit repair method. Background technique [0002] Generally, the light emitting principle of an organic light-emitting diode (OLED) light-emitting device is that electrons are injected into the light-emitting layer (EML) from an electron injection electrode (cathode), and holes are injected into the EML from a hole injection electrode (anode). The holes and electrons injected into the EML recombine in the EML to generate energy and excite electrons. Therefore, when electrons transition from an excited state to a ground state, light is generated along with it, enabling the OLED light emitting device to emit light. At present, there are two schemes for panel design of OL...
