Abstract: A display panel includes a substrate and a first display region. The first display region includes: a light transmission region, a first blocking portion located at a side of the substrate, a second blocking portion located at a side of the first blocking portion away from the substrate, and a first conductive layer located at a side of the second blocking portion away from the first blocking portion. The first conductive layer includes a first hollowed portion and a first non-hollowed portion. The first hollowed portion is located in the light transmission region. Along a first direction, the first blocking portion at least partially overlaps with the second blocking portion, and an overlapping location between the first blocking portion and the second blocking portion at least partially overlaps with the first non-hollowed portion. The first direction is perpendicular to a plane of the substrate.

Abstract: Provided are a display panel and a detection method therefor, and a display device. A first substrate of the display panel includes a first base plate and light-emitting elements. A second substrate opposite to the first substrate includes a second base plate and a retaining wall structure. An orthographic projection of the retaining wall structure onto the first substrate is located between adjacent light-emitting elements. The first substrate includes a first electrode, the second substrate includes a second electrode. In a first direction perpendicular to a plane where the display panel is located, the first electrode and the second electrode at least partially overlap as a first overlap, and the retaining wall structure and the first overlap at least partially overlap. The first and second electrodes are electrically connected to first signal terminal and second signal terminal, respectively.
