The invention discloses an array substrate, a display panel and a display device. The array substrate includes a base substrate and a pixel unit; a first electrode wiring and a second electrode wiring formed on one side of the base substrate; the first electrode wiring Used to provide the first power supply voltage signal to the anode layer of the pixel unit, and the second electrode wiring is used to provide the second power supply voltage signal to the cathode layer of the pixel unit; the first metal wiring formed in the non-display area and surrounding the display area and the second metal wiring, the first metal wiring is electrically connected to the first electrode wiring; the second metal wiring is electrically connected to the second electrode wiring. The first metal wire is electrically connected to the first electrode wire, and the second metal wire is electrically connected to the second electrode wire, so as to reduce the resistance of the transmission wire and reduce the voltage drop of the power signal on the transmission wire. At the same time, the separately provided metal traces are divided into the first metal traces and the second metal traces which are insulated, so as to reduce the stress on the first metal traces and the second metal traces.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of semiconductors, and in particular, to an array substrate, a display panel, and a display device. Background technique [0002] In recent years, Organic Light-Emitting Diode (OLED) has become a very popular emerging flat display area product at home and abroad. This is because OLED displays have self-illumination, wide viewing angle, short response time, high luminous efficiency, and wide color gamut. , low operating voltage, thin panel, large-size and bendable panels and simple manufacturing process, and it also has the potential of low cost. [0003] OLEDs can be divided into two categories: passive drive and active drive according to their driving methods, namely, direct addressing and thin-film transistor (Thin-film transistor, TFT) matrix addressing. Among them, active driving is also called active matrix (ActiveMatrix, AM) type, and each light emitting unit in the AMOLED has in...
