  • Patent number: 10831074
    Abstract: The present disclosure provides an array substrate, a display panel, and an electronic apparatus. The array substrate may include: multiple gate lines each extending along a first linear direction; and multiple data lines each extending along a second linear direction, wherein the multiple gate lines and the multiple data lines are interlaced with each other, the second linear direction is substantially perpendicular to the first linear direction; wherein a notch is defined on the upper edge. By the present disclosure, a wiring path of at least one of the gate lines or at least one of the data lines may avoid the notch. Therefore, a technical problem of uneven distribution of gate lines or data lines and abnormal display image due to the irregular shape of the display panel may be solved.

  • Publication number: 20200192147
    Abstract: The present invention provides a display panel and a display device, including a display area and a notch area disposed at one side of the display area; a thickness of a light shielding film in the notch area is less than a thickness of a light shielding film in the display area. By reducing the thickness of the light shielding film in the notch area, good light transmittance of the notch area is kept. Based on this, the notch area does not need to be cut off, which solves the technical problem that the notch area needs to be cut off in the existing display panels.
