  • Patent number: 11624956
    Abstract: The present disclosure provides a display panel and a display device including the same, in which heights of at least some of metal terminals in a flexible circuit board bonding pad increase in a direction away from a driving chip. Therefore, more space is reserved for connecting traces between the metal terminals and the driving chip, thereby avoiding occurrence of a display abnormality caused by short-circuiting between the connecting traces due to limitation of space for setting the connecting traces and avoiding the metal terminals being too close to a fan-out trace area in order to reduce impedance.

  • Patent number: 11092860
    Abstract: The disclosure provides a display panel and a display device. In an array substrate of the display panel, at least two protrusions are defined on a side of a non-display region away from a display region to form an extending portion. A recess is defined between adjacent protrusions. A driver chip is disposed in a space between a periphery of a display region and a periphery of a non-display region. Distances between the driver chip, the periphery of the display region, and the periphery of the non-display region are increased. A bending section of a flexible circuit board is disposed in the recess. As a result, width of the non-display region will not be increased.
