Touch display panel and display device

A touch display panel, comprising:

• a base substrate, comprising a display region and a peripheral region surrounding the display region;
• and
• a touch metal layer, comprising touch patterns at least partially of which is in the display region, and touch traces in the peripheral region;
• wherein:
• each of the touch pattern comprises a plurality of pattern sub-blocks;
• at least one floating electrode is provided in each of the plurality of pattern sub-block;
• a touch pattern, of the touch patterns, with a partial missing region is regarded as a missing touch pattern;
• and
• in a pattern sub-block where the missing region is located, the at least one floating electrode is integrally and electrically connected with the pattern sub-block;
• wherein in one touch pattern, the pattern sub-block is provided with a plurality of protrusions on an edge of the pattern sub-block toward another pattern sub-block;
• and
• the plurality of protrusions comprise a first convex block and a second convex block arranged sequentially in a direction perpendicular to the edge;
• wherein a width of the second convex block in a direction parallel to the edge is smaller than a width of the first convex block in the direction parallel to the edge;
• wherein the plurality of pattern sub-blocks comprise two first pattern sub-blocks arranged in sequence along a first direction and electrically connected with each other, and two second pattern sub-blocks arranged in sequence along a second direction and electrically connected with each other;
• first pattern sub-blocks of different touch patterns in a same arrangement direction parallel to the first direction are electrically connected to form a first touch electrode;
• and
• second pattern sub-blocks of different touch patterns in a same arrangement direction parallel to the second direction are electrically connected to form a second touch electrode;
• wherein the touch trace comprises a first touch trace electrically connected with the first touch electrode, and a second touch trace electrically connected with the second touch electrode.
