1. An electroluminescent display panel, comprising:

  • a display region, wherein the display region comprises a photosensitive device arranging region and a first normal display region which are arranged in a first direction;

    the display region comprises a plurality of pixels, the plurality of pixels comprise first pixels located in the photosensitive device arranging region and second pixels located in the first normal display region, wherein a region between adjacent first pixels is a light-transmission region, and an arranging density of the first pixels is less than an arranging density of the second pixels;

    the second pixels are arranged in an array, at least one first pixel is arranged in an extending direction of the first direction, in which the second pixels is located, in the photosensitive device arranging region;

    the electroluminescent display panel further comprises a plurality of signal lines extending in the first direction and arranged in a second direction, wherein each signal line is electrically connected to corresponding second pixels arranged in the first direction, and the first direction is perpendicular to the second direction;

    at least one of two adjacent signal lines has an extending line, the extending line is located in the photosensitive device arranging region and overlaps with orthographic projections of the first pixels in a first specific pixel group and a second specific pixel group on a light-emitting surface of the electroluminescent display panel respectively, and the first pixels in the first specific pixel group and the second specific pixel group are electrically connected to one extending line;

    wherein the first specific pixel group and the second specific pixel group comprise respective first pixels located in first straight lines of the second pixels correspondingly connected to two adjacent signal lines, the first specific pixel group and the second specific pixel group are adjacent in the second direction, and the first straight lines extend in the first direction.
