Title
(EN) ANTI-BLUE-LIGHT FILM AND DISPLAY DEVICE THEREOF
(FR) FILM ANTI-LUMIÈRE-BLEUE ET DISPOSITIF D'AFFICHAGE ASSOCIÉ
(ZH) 一种防蓝光膜及其显示器件
Abstract
(EN)
Provided is an anti-blue-light film, comprising a silica substrate (1), a metal nanoparticle structure (2), a graphene layer (3), and a transparent protective layer (4); the anti-blue-light film employs a structure combining metal nanoparticles and a graphene layer; the metal nanoparticles are utilized in the graphene layer, and, when excited by light, produce local plasmon resonance and enhance the absorption of high-energy shortwaves by the graphene layer, thereby effectively preventing the emission of high-energy shortwave blue light which harms the human body. The anti-blue-light film has a broad range of applications and can be arranged in different types of display devices to meet the requirements of different display devices concerning the prevention of the harm of blue light, thus better protecting the human body. Also disclosed is a display device containing the anti-blue-light film; the display device also comprises an outer frame (200), a reflective plate (300), a light-emitting diode (400), a diffusion plate (500), a diffusion sheet (600), a brightness enhancement film (700), and a liquid crystal screen (800). The anti-blue-light film can be arranged on the liquid crystal screen, between the brightness enhancement film and the liquid crystal screen, or between the light-emitting diode and the diffusion plate.

L'invention concerne un film anti-lumière-bleue, comprenant un substrat de silice (1), une structure de nanoparticules métalliques (2), une couche de graphène (3), et une couche protectrice transparente (4) ; le film anti-lumière-bleue utilise une structure combinant des nanoparticules métalliques et une couche de graphène ; les nanoparticules métalliques sont utilisées dans la couche de graphène, et, lorsqu'elles sont excitées par la lumière, produisent une résonance plasmonique locale et améliorent l'absorption des ondes courtes de haute énergie par la couche de graphène, ce qui permet d'empêcher efficacement l'émission d'une lumière bleue à ondes courtes à haute énergie qui blesse le corps humain. Le film anti-lumière-bleue a une large gamme d'applications et peut être agencé dans différents types de dispositifs d'affichage pour satisfaire aux exigences de différents dispositifs d'affichage concernant la prévention des blessures causées par la lumière bleue, ce qui permet de mieux protéger le corps humain. L'invention concerne également un dispositif d'affichage contenant le film anti-lumière-bleue ; le dispositif d'affichage comprend également un cadre externe (200), une plaque réfléchissante (300), une diode électroluminescente (400), une plaque de diffusion (500), une feuille de diffusion (600), un film d'amélioration de luminosité (700), et un écran à cristaux liquides (800). Le film anti-lumière-bleue peut être disposé sur l'écran à cristaux liquides, entre le film d'amélioration de luminosité et l'écran à cristaux liquides, ou entre la diode électroluminescente et la plaque de diffusion.
