Further material types for the first substrate 110 and the second substrate 120 are not enumerated and detailed herein, as would be understood by one of ordinary skill in the art.

Optionally, with continued reference to fig. 2, the magnetic fluid working medium 130 is filled in the accommodating chamber 1100. The magnetic fluid working medium 130 may include a solvent and magnetic particles doped in the solvent to have a color effect.
