Array substrate, manufacturing method thereof, and display apparatus

An array substrate, comprising:

• a substrate;
• a packaging layer over the substrate;
• and
• at least one sensor, each comprising a sensing thin-film transistor and a sensing unit electrically coupled with each other, wherein:
• the sensing thin-film transistor is arranged between the package layer and the substrate;
• and
• the sensing unit is arranged over a side of the package layer away from the substrate;
• wherein the sensing unit of the each of the at least one sensor comprises a third electrode, an active portion, and a fourth electrode, sequentially disposed over a side of the passivation layer distal to the substrate, wherein the third electrode is electrically coupled to the sensing thin-film transistor in the each of the at least one sensor;
• and
• wherein an orthographic projection of the third electrode on the substrate and an orthographic projection of the fourth electrode on the substrate stagger from each other.

A method for manufacturing an array substrate, comprising:

• forming at least one sensing thin-film transistor over a substrate;
• forming a packaging layer over a side of the at least one sensing thin-film transistor distal to the substrate;
• and
• forming at least one sensing unit over a side of the packing layer distal to the substrate, wherein each of the at least one sensing unit is electrically coupled to one of the at least one sensing thin-film transistor corresponding thereto to thereby form one sensor;
• wherein the at least one sensing unit comprises a third electrode, an active portion, and a fourth electrode, sequentially disposed over a side of a passivation layer distal to the substrate, wherein the third electrode is electrically coupled to the one of the at least one sensing thin-film transistor;
• and
• wherein an orthographic projection of the third electrode on the substrate and an orthographic projection of the fourth electrode on the substrate stagger from each other.
