1. A touch control display panel, having a display area and a bonding area disposed on one side of the display area and comprising:
a display layer comprising a plurality of sub-pixels disposed in the display area; and
a touch control layer disposed on one side of the display layer and comprising:
a plurality of touch electrodes disposed in the display area, wherein the touch electrodes are arranged in rows along a first direction and arranged in columns along a second direction, and the first direction is different from the second direction; and
a plurality of touch signal lines correspondingly connected to the touch electrodes by one-to-one and extending to the bonding area;
wherein each of the touch signal lines comprises a main part disposed along the first direction or the second direction and positioned on one side of the sub-pixels and a plurality of extending parts spaced apart from each other and extending from the main part toward an adjacent touch signal line, and one of the sub-pixels is disposed between two adjacent extending parts of a same touch signal line; and
each of the extending parts comprises two extending segments having different lengths, one of the two extending segments and a corresponding extending segment on the adjacent touch signal line are arranged side by side and spaced apart to form a first opening, another one of the two extending segments and another corresponding extending segment on the adjacent touch signal line are arranged side by side and spaced apart to form a second opening, and the first opening and the second opening are staggered from each other;
wherein each of the touch electrodes comprises a plurality of touch main parts extending along the second direction and disposed on the side of the sub-pixels and a plurality of touch extending parts extending from the touch main parts and spaced apart from each other, and the touch main parts are electrically connected to each other; and
wherein each of the touch extending parts comprises two touch extending segments having different lengths, and one of the touch extending parts and a corresponding touch extending part on an adjacent touch main part are arranged side by side and spaced apart to form two staggered openings; or
wherein the one of the touch extending parts and a corresponding extending part on the adjacent touch signal line are arranged side by side and spaced apart to form the two staggered openings.
