Touch unit, method for manufacturing the same and touch display panel

A touch display panel, comprising:

• a base substrate, and a plurality of touch units formed in an array on the base substrate,
• wherein the touch unit comprises at least two sub-units arranged in an array on the base substrate,
• wherein each of the sub-units comprises:
• a first electrode and a second electrode formed on the base substrate, an initial insulation layer being formed between the first electrode and the second electrode, wherein an orthographic projection area of the first electrode on the second electrode is located within an orthographic projection area of the initial insulation layer on the second electrode,
• wherein the first electrodes in each row of the sub-units are sequentially connected to form a first touch line, the second electrodes in each column of the sub-units are sequentially connected to form a second touch line, and each of the first touch lines and each of the second touch lines are connected to a control unit.
