  • Publication number: 20230005410
    Abstract: A display panel and a display device are provided. The display panel includes: a display region and a peripheral region surrounding the display region. The display region comprises a first display sub-region and a second display sub-region. The width-to-length ratio of a channel region of an output transistor in a second gate shift register corresponding to the second display sub-region is decreased so as to reduce the charging time of pixels in the second display sub-region, so that the brightness of the pixels in the second display sub-region is consistent with the brightness region of pixels in the first display sub-region. The configuration facilitates achieving a narrow bezel while improving the display uniformness of the display panel without changing the existing circuit structure and occupying the additional bezel area.
