1. A display panel, comprising:
a first display region and a second display region that are arranged adjacent to each other, wherein:
the second display region is multiplexed as a photosensitive element disposure region,
the first display region includes a plurality of first pixels arranged in an array, and a first pixel of the plurality of first pixels includes a plurality of first sub-pixels with different colors,
the second display region includes a plurality of second pixels arranged in an array, and a second pixel of the plurality of second pixels includes a first region and a second region, wherein the first region has an area less than the second region, and
the first region includes a number of second sub-pixels with different colors, and the second region includes a same number of third sub-pixels with one or more colors, wherein a first sub-pixel, having a first color, of the plurality of first sub-pixels, has an area less than a second sub-pixel, having the same first color, of the plurality of second sub-pixels, and a first sub-pixel, having a second color, of the plurality of first sub-pixels, has an area less than a second sub-pixel, having the same second color, of the plurality of second sub-pixels, and the second sub-pixel having the first color or the second color has an area less than a third sub-pixel of the plurality of third sub-pixels, wherein the second color is different from the first color; and
a first substrate and a second substrate that are oppositely disposed, wherein the first substrate is provided with a plurality of signal lines, the plurality of signal lines at least include scan lines and data lines, and the scan lines and the data lines are isolated and crossed to define regions where the first sub-pixel, the second sub-pixel, and the third sub-pixel are located, wherein:
a signal line of the plurality of signal lines in the second display region is made of a transparent conductive material.
