Display panel and display apparatus having a touch functional layer

A display panel, having a display region, and a first fanout region, a bending region, a second fanout region and a bonding region located on a side of the display region and sequentially away from the display region;

• and an area of the second fanout region is greater than an area of the first fanout region;
• the display panel comprising:
• a display substrate, including:
• a first power supply voltage line including a first connection portion and a second connection portion that are both located in the first fanout region, the bending region and the second fanout region;
• the first connection portion and the second connection portion are respectively located on opposite sides of a center line extending in a second direction of the display panel;
• and
• a touch functional layer disposed on the display substrate and including:
• a plurality of touch units disposed in the display region;
• at least portion of each of a plurality of touch lines, each touch unit being electrically connected to at least one touch line;
• wherein the plurality of touch lines extend from the display region to the second fanout region sequentially through the first fanout region and the bending region;
• the plurality of touch lines include first touch line groups and second touch line groups, and an average resistance of all touch lines of a first touch line group is greater than an average resistance of all touch lines of a second touch line group;
• and
• all the touch lines of the first touch line group are assembled to the bonding region;
• and
• a plurality of compensation lines each bent at least once in the second fanout region and assembled to the bonding region;
• wherein the plurality of compensation lines include compensation line groups that are in one-to-one correspondence with the second touch line groups, at least one compensation line of each compensation line group is electrically connected to at least one touch line of a respective second touch line group;
• wherein the first touch line groups and the second touch line groups include:
• one first-side first touch line group, two first-side second touch line groups, one second-side first touch line group and one second-side second touch line group that are sequentially disposed in a direction which is from the first connection portion to the second connection portion in a first direction;
• orthogonal projections of the first-side first touch line group and the first-side second touch line groups on the display substrate each overlap with an orthogonal projection of the first connection portion of the first power supply voltage line on the display substrate;
• and
• orthogonal projections of the second-side first touch-control line group and the second-side second touch line group on the display substrate each overlap with an orthogonal projection of the second connection portion of the first power supply voltage line on the display substrate;
• the first direction is substantially parallel to a boundary line between the first fanout region and the display region, and the second direction is substantially perpendicular to the first direction.
