Title:
LIQUID APERTURE, ELECTRONIC DEVICE, AND DRIVING METHOD AND DRIVING APPARATUS FOR LIQUID APERTURE
Document Type and Number:
WIPO Patent Application WO/2021/238565
Kind Code:
A1
Abstract:
Provided are a liquid aperture, an electronic device, and a driving method and a driving apparatus for a liquid aperture. The liquid aperture comprises a first substrate, a first electrode pad, an insulating layer, a hydrophobic layer, a hydrophilic layer, a retaining wall, a second electrode pad and a second substrate which are sequentially and adjacently arranged in the optical axis direction of the liquid aperture, wherein a first hollow structure is formed in the middle of the retaining wall; the hydrophilic layer comprises a first hydrophilic part and a second hydrophilic part, N second hollow structures being present between the first hydrophilic part and the second hydrophilic part; the first hollow structure is in communication with the N second hollow structures to form a closed cavity; the closed cavity is filled with a transparent electrolyte and colored ink, the colored ink being incompatible with the transparent electrolyte; and an electric field is formed between the first electrode pad and the second electrode pad to change the distribution of the transparent electrolyte and the colored ink in the closed cavity. The size of a light entrance hole of the liquid aperture can be adjusted by means of controlling the voltage applied to the first electrode pad and the second electrode pad.
