  • Publication number: 20240120344
    Abstract: Embodiments of the present disclosure are directed to a display panel and a display device. A width of the fan-out wire positioned at the outer side is increased such that the impedance of the outer fan-out wire could be reduced. Furthermore, the second part of the second fan-out wire is bended in a direction away from the display region. This means that the second part only occupies the right/left redundant space and thus the second fan-out wire consumes less space of the lower side frame and the width of the fan-out region decreases. The present disclosure could achieve both comparatively low impedance of the fan-out wire and a narrow side frame.
