Definitions

  • a display device includes:
  • a display panel and a functional film attached to the display panel ;
  • the display panel includes a polarizer, and the cleaning film layer is fixedly connected to the polarizer through the adhesive layer.
  • the base includes an adhesive layer and a substrate fixedly connected to the adhesive layer, and the driving electrode and the cleaning film layer are arranged on the substrate.
  • Polar liquid crystal molecules undergo anisotropic deformation after being stimulated by an electric field, shrink in the long axis direction of the polar liquid crystal molecules and expand in the direction perpendicular to the long axis.
  • an AC electric field is applied to the polar liquid crystal molecules to make the surface morphology of the cleaning film 23 change as the AC electric field changes, so as to realize the self-cleaning effect of one-key control from the outside world.
  • Water can be used in any area without being restricted by cleaning tools and materials. It is convenient and fast, environmentally friendly, harmless to the human body, and can prevent damage to precision devices in the display device.
  • the substrate 211 is a flexible transparent substrate 211, and the material of the substrate 211 is polyethylene terephthalate (PET) or polyimide (PI).

  • PI polyimide
  • the display panel 10 includes a polarizer 11 and a light guide plate 12, and the cleaning film layer 23 is fixedly connected to the polarizer 11 or/and the light guide plate 12 through the adhesive layer 212.
  • the cleaning mold layer is driven by an AC electric field, the surface morphology of the cleaning mold layer is changed, which is similar to macroscopic surface vibration to achieve self-cleaning.
  • the actual cleaning process is about 0.9s can achieve the effect of cleaning the dust, because the actual use process does not involve chemical reactions of substances, so the actual use times can be more than 500 times verified by experiments, which is convenient, fast, and safe and reliable.

Abstract

L'invention concerne un dispositif d'affichage et un procédé de fabrication associé. Le dispositif d'affichage comprend un panneau d'affichage (10) et une couche de film fonctionnel (20) ; la couche de film fonctionnel (20) comprend un substrat (21), une électrode d'attaque (22) disposée sur le substrat (21) et une couche de film de nettoyage (23) recouvrant l'électrode d'attaque (22) ; la couche de film de nettoyage (23) comprend des molécules de cristaux liquides polaires portant des groupes acrylate et l'électrode d'attaque (22) fournit un champ électrique à courant alternatif pour les molécules de cristaux liquides polaires. Sous l'action du champ électrique à courant alternatif, la surface de la couche de film de nettoyage se modifie avec le changement du champ électrique à courant alternatif, produisant une vibration de surface similaire à une vibration macroscopique, de façon à obtenir l'effet de nettoyage, de telle sorte à nettoyer l'intérieur et l'extérieur d'un dispositif d'affichage. Ledit dispositif d'affichage peut être utilisé à l'extérieur ou dans des régions qui connaissent des problèmes d'approvisionnement en eau ayant un climat aride, ne se limitant pas à un outil de nettoyage, étant pratique et efficace et respectueux de l'environnement, n'étant pas nocif pour le corps humain et pouvant éviter des dommages à des parties de précision dans le dispositif d'affichage.
