Claim 0:
1. An optical switch, comprising:
a plurality of micro-grooves;
a micro-fluid disposed in each micro-groove of the plurality of micro-grooves;
a driving electrode disposed corresponding to the micro-fluid in each micro-groove, the driving electrode being configured to provide a voltage to a corresponding micro-fluid to control light transmittance of a region where the micro-fluid is located;
a first substrate and a second substrate that are disposed opposite to each other; and
a plurality of light-shielding portions disposed between the first substrate and the second substrate, the plurality of light-shielding portions enclosing the plurality of micro-grooves on the first substrate or the second substrate;
wherein the driving electrode includes a first electrode and a second eletrode that are disposed opposite to each other, and at least one third electrode on an inner side wall of each micro-groove;
the micro-fluid is located between a corresponding first electrode and a corresponding second electrode; and
one of the first electrode and the second electrode is electrically connected to the at least one third electrode, and the other of the first electrode and the second electrode is insulated from the at least one third electrode.
