Electrochromic device and application thereof

Abstract

The invention provides an electrochromic device and application thereof. The electrochromic device comprises a first transparent conducting layer, a color changing layer and a second transparent conducting layer, wherein the first transparent conducting layer comprises a first conducting part and a second conducting part; the second transparent conducting layer comprises a third conducting part and a fourth conducting part, the color-changing layer is located between the first conducting part and the third conducting part, the color-changing layer, the first conducting part and the third conducting part jointly form a film main body part, the second conducting part is bent to form a first bent part, and the fourth conducting part is bent to form a second bent part; and the first bent partand the second bent part are respectively provided with an electrode lead. The electrochromic device provided by the invention can be applied as a display screen protective film, can be applied to a rear shell or a protective shell of electronic terminal equipment, and can be applied to the electronic terminal equipment with a camera to realize an integrated color changing effect.

Description

technical field [0001] The invention belongs to the technical field of electrochromism, and relates to an electrochromic device and its application. Background technique [0002] With the continuous development of science and technology, there are more and more types of electronic terminal equipment such as mobile phones. When purchasing such electronic terminal equipment, consumers pay more and more attention to the appearance of the electronic terminal equipment in addition to the performance of the electronic terminal equipment itself. Variety and personalization. At present, some manufacturers set multiple colors on the casing of the electronic terminal equipment when it leaves the factory, in order to attract consumers. However, once the color of the shell is set, it will not change again, and it will only give consumers a sense of freshness for a short time, and cannot attract consumers for a long time. Therefore, more consumers will choose to put a personalized shel...

AI Technical Summary

Problems solved by technology

Although the electrochromic film provided by this patent has color changeability, but its edge needs to be provided with wiring to connect to the external circuit and be packaged, resulting in a circle around the edge of the electrochromic film that cannot change color, so that when the electrochromic film changes color , the discoloration of the back shell of the mobile phone cannot achieve an integrated effect

At the same time, because some current electronic terminal equipment, such as mobile phones, tablets, etc., have some special functional areas, such as fingerprint areas, cameras, flash lights, etc., some functional areas are still protruding, such as protruding cameras, resulting in the current electrochromic film. Unable to meet application requirements
