AI Technical Summary

Technical Problem

Existing privacy display devices cannot flexibly switch between privacy mode and non-privacy mode, and affect the brightness for normal use.

Method used

The system employs a light-transmitting unit and a privacy unit positioned between a first substrate and a second substrate. By controlling the first electrode and the second electrode to generate an electric field, the electrochemical solute reacts under different electric fields, changing the ion concentration within the cavity, thereby achieving the switching between privacy mode and non-privacy mode.

Benefits of technology

It enables flexible switching between privacy mode and non-privacy mode for display products, avoids power consumption during the switching process, has fast response capability, and maintains normal display brightness and clarity in non-privacy mode.

Abstract

The application discloses a kind of peep-proof structure and display device, the peep-proof structure includes oppositely arranged first substrate and second substrate, and a plurality of light-transmitting units and a plurality of peep-proof units are arranged between the first substrate and the second substrate, the peep-proof unit includes retaining wall, flexible semi-permeable membrane, colorant, electrochemical reaction solute, low ion concentration transparent solution, first electrode and second electrode, flexible semi-permeable membrane divides peep-proof cavity into first cavity and second cavity, flexible semi-permeable membrane only allows solvent molecule to permeate, when first electrode and second electrode provide first electric field, electrochemical reaction solute occurs first reaction, and ion concentration in first cavity increases;When first electrode and second electrode provide second electric field, electrochemical reaction solute occurs second reaction, and ion concentration in first cavity decreases.By the above design, flexible switching between peep-proof mode and non-peep-proof mode can be realized.
