Touch display panel

A touch display panel, comprising:

• an array substrate, the array substrate comprising:
• a first glass substrate,
• a plurality of scan lines extending along a first direction, a plurality of data lines extending along a second direction, wherein two adjacent scan lines intersect with two adjacent data lines to define a sub-pixel with a ratio of a long edge to a short edge being M:1, the long edge of the sub-pixel extends along the second direction and the short edge of the sub-pixel extends along the first direction;
• adjacent M′ sub-pixels along the first direction constitute a pixel group, M′ is a rounding off integer of M, and M′ is a natural number greater than 1, and
• a plurality of common electrodes each being block-shaped and arranged in an In matrix, wherein each of I and J is a natural number greater than or equal to 2, each of the plurality of common electrodes is correspondingly connected to at least one touch electrode wiring, and each of the plurality of common electrodes is connected to a touch drive circuit by the at least one touch electrode wiring;
• and
• wherein the touch display panel further comprises:
• a black matrix comprising a plurality of open areas, each of the plurality of open areas corresponding to a respective sub-pixel, and
• a plurality of color resistors comprising N colors, overlapping the plurality of open areas, and arranged along the first direction;
• wherein the color resistors with N colors are alternatively arranged, N is a natural number greater than 1,
• wherein each of the plurality of common electrodes overlaps with k*Z sub-pixels in the first direction, k is a positive integer, and Z is a least common multiple of M′ and N.
