Publication number: 20220392408Abstract: 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.Type: ApplicationFiled: July 5, 2021Publication date: December 8, 2022Inventors: Xin ZHANG, Yang ZHOU, Yi QU, Dongxiao SHAN, Yi ZHANG, Linhong HAN
