Abstract: The present disclosure relates to a dummy pixel circuit, a display panel, and a display device, which belongs to the field of display. The dummy pixel circuit is applicable to a display panel provided with two through vias and disposed between the two through vias, and the dummy pixel circuit includes a pixel sub-circuit and a dummy sub-circuit. The pixel sub-circuit includes one or more first transistors, wherein a control electrode of the first transistor is electrically connected to the first gate line. The dummy sub-circuit includes one or more second transistors, wherein a control electrode of the dummy sub-circuit is electrically connected to the first gate line, a first electrode of the second transistor is electrically connected to a first electrode of a corresponding one of the one or more first transistors, and a second electrode of the second transistor is electrically connected to a second electrode of the corresponding first transistor. Each of the one or more first transistors corresponds to at least one of the one or more second transistors. The second transistor consumes the power transmitted transferred by the first gate line, and thus a total load of the pixel circuit electrically connected to the first gate line is increased. In this way, the pixel, to which the pixel circuit electrically connected to the first gate line corresponds, has an increased luminance, thereby mitigating display mura of display panel.

Abstract: The present disclosure belongs to the field of displays, and relates to a display panel and a display device. The display panel has a display region and a peripheral region. The display panel comprises a substrate, a driving circuit, and a plurality of first signal pins. The driving circuit is located on the substrate. The plurality of first signal pins are located on the substrate and are arranged at intervals in the peripheral region, and the plurality of first signal pins are electrically connected to the driving circuit. The plurality of first signal pins comprise at least two first pins, and the at least two first pins are electrically connected. Because the at least two first pins are already electrically connected, voltage signals outputted by the at least two first pins to the driving circuit may be balanced, thereby balancing the voltage signals outputted by the driving circuit to a light emitting element, and improving the uniformity and stability of the voltage signals. Thus, the display effect of the display panel is improved.
