Abstract

The invention provides a liquid aperture, electronic equipment, and a driving method and a driving device of the liquid aperture. The liquid aperture comprises a first substrate, a first electrode plate, an insulating layer, a hydrophobic layer, a hydrophilic layer, a retaining wall, a second electrode plate and a second substrate which are sequentially and adjacently arranged in the optical axis direction of the liquid aperture; 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, and N second hollow structures exist between the first hydrophilic part and the second hydrophilic part; the first hollow structure and the N second hollow structures are communicated to form a closed cavity; the closed cavity is filled with transparent electrolyte and colored ink, and the colored ink is incompatible with the transparent electrolyte; and an electric field is formed between the first electrode plate and the second electrode plate to change the distribution of the transparent electrolyte and the colored ink in the closed cavity. The size of the light inlet hole of the liquid aperture can be adjusted by controlling the voltage applied to the first electrode plate and the second electrode plate.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010477421.9 and the application title "Liquid Aperture" filed with the China Patent Office on May 29, 2020, the entire contents of which are incorporated herein by reference. technical field [0002] The present application relates to the field of terminal equipment, and in particular to a liquid aperture, electronic equipment, a driving method and a driving device for the liquid aperture. Background technique [0003] The aperture is a component in the camera that controls the amount of light entering. The traditional aperture is composed of mechanical blades. The more blades, the closer the opening is to a circle, but at the same time, the greater the thickness, the worse the reliability. Such as Figure 1a and Figure 1b The structure of the traditional aperture 1' shown is schematic. The traditional aperture 1' has a plurality of mechanical blades 11', and the cen...
