Abstract
The present disclosure provides a power supply circuit, an array substrate, and a display device. The power supply circuit includes a plurality of power wires, each providing a voltage to a row of pixel units. The plurality of power wires include at least a first power wire and a second power wire, between which at least one logical AND circuit is disposed. The logical AND circuit electrically econnects the first power wire with the second power wire when high level voltages are output by the first power wire and the second power wire simultaneously. As a result, voltages at connection points of two rows of power wires approximate to each other, voltage differences among different rows of pixel units are reduced, and therefore the phenomenon of luminance nonuniformity in a display caused by different voltage drops of different rows of pixel units is improved.
