1. A display panel, comprising:
a primary contour line defining an active display region, and a closed secondary contour line inside the primary contour line and not intersecting the primary contour line,
wherein the primary contour line is an outer contour after the display panel is lightened;
the primary contour line comprises one or more first portions extending non-linearly, and the secondary contour line comprises one or more second portions extending non-linearly;
pixels in the active display region of the display panel comprise pixels of a first type, pixels of a second type and pixels of a third type, an entirety of the pixels of the first type is located inside the secondary contour line, the pixels of the second type intersect the second portion, and the pixels of the third type intersect the first portion and an entirety of the pixels of the third type is located outside the secondary contour line; and
an aperture ratio of the pixels of the third type is smaller than an aperture ratio of the pixels of the first type, and an aperture ratio of at least part of the pixels of the second type is positively correlated with an area of a part, inside the secondary contour line, of each of the pixels of the second type.
