Array substrate and preparation method therefor, and touch-control display apparatus

An array substrate, comprising:

• an underlay substrate, and a plurality of first signal lines, a plurality of second signal lines, a plurality of touch signal lines, a first transparent conductive layer, and a second transparent conductive layer disposed on the underlay substrate, wherein:
• the first transparent conductive layer and the second transparent conductive layer are located at a side of the plurality of touch signal lines away from the underlay substrate;
• a touch signal line is connected with at least one touch sensing block, wherein the touch sensing block comprises a plurality of touch electrodes connected with each other and spaced apart, and the first transparent conductive layer or the second transparent conductive layer comprises the plurality of touch electrodes;
• the plurality of first signal lines and the plurality of second signal lines are intersected to form a plurality of sub-pixel regions, wherein each sub-pixel region comprises an opening region;
• and an orthographic projection of the touch signal line on the underlay substrate and an orthographic projection of the opening region of at least one sub-pixel region on the underlay substrate are overlapped;
• the opening region of each sub-pixel region is located in a display region and configured for display;
• within the opening region of the sub-pixel region, the touch signal lines are shielded by the plurality of touch electrodes;
• distances from the touch signal line to two second signal lines adjacent to the touch signal line are substantially the same;
• at least one touch sensing block comprises a plurality of touch electrode groups arranged in sequence;
• and at least one touch electrode group comprises a second plurality of touch electrodes spaced apart and a first connecting unit electrically connected to the second plurality of touch electrodes;
• and
• the touch sensing block further comprises:
• a second connecting unit located between adjacent touch electrode groups and electrically connected to the adjacent touch electrode groups.
