Array substrate and touch display device

An array substrate comprising:

• a plurality of pixels arranged in an array, wherein each pixel comprises N sub-pixels of different colors arranged along a first direction, and N≥3;
• a plurality of touch sensor units arranged in an array, wherein each touch sensor unit corresponds to m*N sub-pixels in the first direction, and m is a positive integer;
• a plurality of touch signal lines, wherein each touch sensor unit is connected with at least one touch signal line;
• wherein along the first direction, each touch sensor unit in a same row is connected with a same number of touch signal lines, each touch signal line is connected with a corresponding touch sensor unit through an access point, and the access points of the touch signal lines connected to a same row of touch sensor units are in a same sub-pixel color environment,
• wherein the access points of the plurality of touch signal lines are in at least two colors of sub-pixels,
• wherein the array substrate comprises at least one touch display area, and in each touch display area, access points of touch signal lines connected to the same row of touch sensor units are between same adjacent two colors of sub-pixels.
