Abstract

The present invention discloses an array substrate, a display panel and a display device. The array substrate comprises: a substrate and a pixel unit; a first electrode wiring and a second electrode wiring formed at one side of the substrate, wherein the first electrode wiring is configured to provide first power voltage signals to the anode layer of the pixel unit, and the second electrode wiringis configured to provide second power voltage signals to the cathode layer of the pixel unit; and a first metal wiring and a second metal wiring formed at a non-display area and enclosing a display area, wherein the first metal wiring and the first electrode wiring are electrically connected, and the second metal wiring and the second electrode wiring are electrically connected. The first metal wiring and the first electrode wiring are electrically connected, and the second metal wiring and the second electrode wiring are electrically connected to reduce the transmission wiring resistance andreduce the voltage drops of power supply signals on the transmission wirings. The individually arranged metal wirings are divided into the first metal wiring and the second metal wiring which are arranged in an insulation mode so as to reduce the stress on the first metal wiring and the second metal wiring.

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...
