Disclosed herein is an organic lighting apparatus that can reduce leakage current. The organic lighting apparatus includes a plurality of light-emitting portions, each of which has a first electrode including an electric current injection line, wherein the electric current injection line includes one or more fuse structures. With the electric current injection line including a fuse structure, when a short circuit occurs between first and second electrodes in a specific light-emitting portion, the fuse operates and prevents electric current from being injected into the short-circuited light-emitting portion, thereby making it possible to reduce leakage current.

An organic light-emitting diode display panel, a method of manufacturing the same, and a display device are provided. The organic light-emitting diode display panel includes a flexible substrate defined with a test circuit region thereon. The test circuit region is provided with a test circuit and defined with a circuit trace region. The circuit trace region includes a plurality of traces, a plurality of transistors, a control line, and at least one pin. Each one of the traces is connected to one of the transistors. The control line is electrically connected to a control end of each of the transistors to turn on or turn off the transistors to avoid the circuit from short-circuiting.

A display device includes a data line extending in a first direction, a scan line extending in a second direction crossing the first direction, a wire extending in the second direction, and a bridge electrically connecting the wire to the data line, where the wire includes a branch protruding from the wire in the first direction, and the bridge overlaps the data line and the branch of the wire.

A display apparatus includes a first substrate including a display area and a peripheral area on a side of the display area, a second substrate facing the first substrate, a fan-out portion arranged in the peripheral area and including a plurality of wires, a power supply line arranged over the fan-out portion and in the peripheral area, an insulating layer arranged between the plurality of wires and the power supply line, and a sealing portion arranged in the peripheral area. The sealing portion surrounds a periphery of the display area and attaches the first substrate and the second substrate to each other. The peripheral area includes an overlapping area in which the fan-out portion, the power supply line, and the sealing portion overlap one another. The power supply line arranged in the overlapping area includes a first conductive layer and a second conductive layer arranged on the first conductive layer.

An electronic device may have a display such as an organic light-emitting diode (OLED) display. The OLED display may have an array of OLED pixels that each have OLED layers interposed between a cathode and an anode. The pixels may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The distance between the partially transparent cathode layer and the reflective anode structure for a pixel may be selected such that light at the wavelength emitted by the pixel forms a standing wave between the anode and the cathode. The standing wave may have only one anti-node and the emissive layer for the pixel may be aligned with that one anti-node. To mitigate short circuits, a roughness reduction layer and/or short-circuit-reducing layer having a high sheet resistance may be formed between the anode the OLED layers.

An array substrate includes a base, conductive structures, a peripheral trace, a first insulating layer and a second insulating layer.
