• first signal lines located in the display region, wherein at least part of each first signal line of the first signal lines extends in a first direction, and the first signal lines are arranged in a second direction intersecting with the first direction, wherein the first signal lines comprise at least one first-type signal line and at least one second-type signal line, wherein one of the at least one first-type signal line at least partially surrounds the at least two functional component regions, the at least one second-type signal line comprises a control signal line, and the at least one second-type signal line is broken at two sides of one functional component region of the at least two functional component regions in the first direction;
• a first non-display region located between the display region and one of the at least two functional component regions;
• a second non-display region at least partially surrounding the display region;
• a first-type driving circuit located in the second non-display region and electrically connected to one of the at least one first-type signal line and located at a side of the display region in the first direction;
• and
• second-type driving circuits located in the second non-display region and electrically connected to the control signal line and located at two sides of the display region in the first direction, wherein the display region located between the first functional component region and the second functional component region is provided with sub-pixels for display, the sub-pixels for display are connected to the second-type driving circuits adjacent to one of the at least two functional component regions by the second-type signal line;
• wherein the at least one first-type signal line comprises at least one first-type connecting line, wherein one of the at least one first-type connecting line electrically connects parts of one first-type signal line of the at least one first-type signal line that are located at two sides of one of the at least one functional component region,
• wherein the display panel further comprises pixel driving circuit groups arranged in the display region along the second direction, wherein each pixel driving circuit group of the pixel driving circuit groups comprises at least two pixel driving circuit rows arranged in the second direction, wherein each pixel driving circuit row of the at least two pixel driving circuit rows comprises pixel driving circuits arranged in the first direction,
• wherein the at least one first-type signal line comprises a plurality of first-type signal lines, the first-type driving circuit comprises first-type driving units that are cascaded, wherein one of the first-type driving units is electrically connected to the at least two pixel driving circuit rows in one pixel driving circuit group of the pixel driving circuit groups through at least two first-type signal lines of the plurality of first-type signal lines, and
• wherein the display panel further comprises at least one first jointing line, wherein at least two of the plurality of first-type signal lines that are electrically connected to the at least two pixel driving circuit rows in one pixel driving circuit group of the pixel driving circuit groups are electrically connected to one of the at least one first jointing line, and the one of the at least one first jointing line is electrically connected to the at least one first-type connecting line.
