Abstract
A liquid aperture, an electronic device, and a driving method and apparatus for a liquid aperture are provided. The liquid aperture includes a first substrate, a first electrode plate, an insulation layer, a hydrophobic layer, a hydrophilic layer, a sidewall, a second electrode plate, and a second substrate that are disposed adjacent to each other in sequence in a direction of an optical axis of the liquid aperture. A first hollow structure is formed in a middle of the sidewall. The hydrophilic layer includes a first hydrophilic part and a second hydrophilic part. There are N second hollow structures between the first hydrophilic part and the second hydrophilic part. The first hollow structure communicates with the N second hollow structures to form a closed cavity. The closed cavity is filled with a transparent electrolyte and dyed oil. The dyed oil is incompatible with the transparent electrolyte.
