Tunable band-stop filter, method of driving the same and electronic device

A tunable band-stop filter, comprising:

• a first substrate comprising a first base substrate and a wire structure on the first base substrate;
• a second substrate comprising a second base substrate and a common electrode on the second base substrate;
• and
• a liquid crystal layer between the first substrate and the second substrate,
• wherein the wire structure comprises a first wire structure and a second wire structure, and a first endpoint of the first wire structure is connected to a first endpoint of the second wire structure, a second endpoint of the first wire structure is connected to a second endpoint of the second wire structure,
• the first endpoint of the first wire structure and the first endpoint of the second wire structure are configured to input electromagnetic wave signals, the second endpoint of the first wire structure and the second endpoint of the second wire structure are connected and configured to output the electromagnetic wave signals, the first wire structure, the common electrode and a liquid crystal layer between the first wire structure and the common electrode constitute a first phase modulation structure, and the second wire structure, the common electrode and a liquid crystal layer between the second wire structure and the common electrode constitute a second phase modulation structure.
