Claim 7:
8. A touch display panel, wherein the touch display panel comprises:
a display panel comprising a display area; and
a touch component comprising a first area and a second area disposed corresponding to the display area, wherein the first area is disposed adjacent to the second area, and the touch component comprises:
a plurality of first touch electrode lines disposed in the first area;
a plurality of touch electrodes disposed in the second area; and
a plurality of second touch electrode lines disposed in the second area, wherein the plurality of second touch electrode lines are connected between the plurality of first touch electrode lines and the plurality of touch electrodes, and an interval between two adjacent second touch electrode lines is greater than a minimum interval between two adjacent first touch electrode lines;
wherein the plurality of touch electrodes comprises:
first type touch electrodes; and
second type touch electrodes, wherein in a first direction, the second type touch electrodes are arranged side by side with the first type touch electrodes, and a size of the first type touch electrodes is different from a size of the second type touch electrodes, wherein the first direction is a direction in which the second area points to the first area;
wherein in the first direction, the first type touch electrodes have a first height L1, the second type touch electrodes have a second height L2, the first area has a first size D1, and a number of the second type touch electrodes disposed in a same row with at least one of the first type touch electrodes is N, wherein N is an integer greater than or equal to 1, and the first size D1 is equal to an interval from the touch electrodes close to the plurality of first touch electrode lines to the first edge;
wherein the first height L1, the second height L2, the first size D1, and N satisfy following formula:

L2=L1−D1/N.
