  • the difference from Embodiment 5 of the double glare film is that the base material of the second glare film is replaced by a water-oxygen barrier film 160 , that is, the water-oxygen barrier film is used as the film base material.
  • the difference from the second embodiment of the double glare film is that the electrochromic device is an EC device, and the base material of the second glare film is replaced by a water-oxygen barrier film 160 .
  • the side closer to the field of vision is the outer side, and the side farther away from the field of vision is the inner side.
  • the first glare film is close to the field of view, and it only has a texture layer and a coating layer, without an ink layer, and is in a semi-transparent state as a whole.
  • the second glare film is far away from the field of view, and its texture layer, coating layer and ink layer can all be selectively set.
  • the film substrate is made of transparent materials, such as glass, plastic, film, etc.; the transparent optical glue is made of OCA; the texture layer is UVpattern; the coating layer is NCVM.
  • setting the compound color-changing device in the protective case of the mobile phone and other electronic equipment has the following advantages: 1.
  • the compound color-changing device has a certain thickness and is arranged on the back of the mobile phone The thickness of the mobile phone will be significantly increased in the cover, and the protective shell is not sensitive to the increase in thickness; 2.
  • the composite color-changing device cannot be replaced in the back cover of the mobile phone, but it is easy to replace in the mobile phone shell, which can make any mobile phone have a color-changing function.
  • the above-mentioned embodiment of the double glare film using the co-film base material can reduce the overall thickness of the composite color-changing device.

Abstract

Le présent modèle d'utilité concerne le domaine technique des dispositifs de changement de couleur, et concerne un boîtier de protection de dispositif électronique à changement de couleur alimenté. Un dispositif de changement de couleur alimenté est situé sur un côté extérieur, et un film anti-reflet est situé sur un côté intérieur du dispositif de changement de couleur alimenté, ou le dispositif de changement de couleur alimenté est situé au milieu, et deux films anti-reflet sont situés sur deux côtés du dispositif de changement de couleur alimenté respectivement. Lorsque le dispositif de changement de couleur alimenté est dans différents états, les états peuvent être superposés avec la couleur et la texture d'un film anti-reflet, de sorte que différents effets visuels peuvent être présentés.
