Smell-diffusing cell array substrate, apparatus for transferring smell information and electronic device including the apparatus

摘要

A smell-diffusing cell array substrate, an apparatus configured to transfer smell information and an electronic device are provided, the smell-diffusing cell array substrate includes at least one smell-diffusing cell having a microcapsule with a core-shell structure. A shell of the microcapsule includes a wall material and a photocatalyst dispersed in the wall material. A core of the microcapsule includes a smell-diffusion material and a hydrophilic liquid.

1. A smell-diffusing cell array substrate, comprising:
at least one smell-diffusing cell that includes a microcapsule having a core-shell structure, wherein a shell of the microcapsule includes a wall material and a photocatalyst dispersed in the wall material, and a core of the microcapsule includes a smell-diffusing material and a hydrophilic liquid, wherein the smell-diffusing cell array substrate is configured to control diffusion of a smell of the smell-diffusing material through the shell by changing exposure of the at least one smell-diffusing cell to UV rays such that hydrophilicity of the photocatalyst increases as exposure of the at least one smell-diffusing cell to the UV rays increases, and the hydrophilicity of the photocatalyst decreases when the exposure of the at least one smell-diffusing cell to the UV rays is stopped; and wherein when UV rays are radiated on the microcapsule, the photocatalyst is dissolved in the hydrophilic liquid to form a crack in the shell through which the smell of the smell-diffusing material is diffused, and when UV radiation is stopped, the hydrophilicity of the photocatalyst dissolved in the hydrophilic liquid decreases and the photocatalyst is precipitated such that the crack in the shell is at least partially filled with the precipitated photocatalyst.
