Array substrate, display panel, display device and display method

An array substrate comprising:

• a display region provided with a plurality of data lines therein;
• and
• a wiring region located around the display region and provided with a plurality of leading wires therein,
• wherein:
• the plurality of leading wires are connected with the plurality of data lines respectively in a one-to-one correspondence way;
• the plurality of leading wires comprise a plurality of first leading wires and a plurality of second leading wires, which are insulatively arranged in different layers;
• and
• the plurality of first leading wires and the plurality of second leading wires comprise at least one pair of up-and-down overlapped first and second leading wires to which data signals having the same polarity are input,
• wherein:
• each of the first and second leading wires comprises a leading wire body and a first bended connection end for connecting with a data line;
• the leading wire body of each first leading wire is up-and-down overlapped with that of each corresponding second leading wire;
• the first bended connection end of each first leading wire has a bending direction opposite to a bending direction of the first bended connection end of each corresponding second leading wire;
• and
• the first bended connection end of each second leading wire crosses a first bended connection end of another first leading wire adjacent to a corresponding first leading wire overlapped with the second leading wire.
