Pixel structure, display panel, manufacturing and control method thereof

A method of manufacturing a display panel, the display panel comprising a plurality of pixel structures, the method comprising:

• providing a first electrode and a second electrode, at least one of the first electrode and the second electrode being a transparent electrode;
• forming a retaining wall on the first electrode, wherein the retaining wall and the first electrode together form a receiving recess;
• injecting a target liquid into the receiving recess;
• and
• placing the second electrode on the retaining wall to seal the receiving recess and thereby forming a sealed cavity, and the target liquid being within the sealed cavity;
• wherein the target liquid contains a plurality of particles, and the plurality of particles are configured to form photonic crystals with different lattice spacing under an action of different electric fields between the first electrode and the second electrode.
