Description

Technical Field

[0001] The utility model relates to the field of electronic products, in particular to a color-changing touch component and an electronic device. Background Art

[0002] As a closed shell of electronic products, the cover plate is often used in various industries, such as mobile phones, car products, etc. Taking a mobile phone as an example, a cover plate is usually provided on the front of the mobile phone to protect the display screen of the mobile phone.

[0003] At present, the cover of a mobile phone is usually directly covered on the display screen of the mobile phone. When the display screen is in the off state, the non-display area is usually black due to the black ink layer, while the color of the display screen itself in the display area is usually dark gray. Therefore, there is a visual difference in color between the window area and the non-window area of ​​the cover, which affects the visual effect.

[0004] In order to solve the above technical problems, a Chinese patent with patent number 202010186796.X discloses a cover assembly, comprising: a transparent cover having an inner surface, a window area and a non-window area adjacent to the window area; an ink layer, arranged on the inner surface, for defining the window area and the non-window area on the transparent cover; an electrochromic layer, adhered to the inner surface in direct contact, connected to the ink layer, and corresponding to the window area, the electrochromic layer having a colored state and a transparent state, wherein, when the electrochromic layer is in a colored state, at least the color of the connection between the electrochromic layer and the ink layer is consistent with the color of the ink layer. The electrochromic layer of the cover assembly is directly attached to the inner surface of the transparent cover, connected to the ink layer, and corresponds to the window area. The electrochromic layer has a colored state and a transparent state. When the electrochromic layer is in the colored state, at least the color of the connection between the electrochromic layer and the ink layer is consistent with the color of the ink layer, so that the visual boundary between the window area and the non-window area of ​​the cover assembly is not obvious, presenting an integrated visual effect.

[0005] However, as an electronic device, the electrochromic layer will inevitably accumulate static electricity during use. If the electrochromic layer accumulates too much static electricity, it will damage its internal circuit and affect the color-changing effect. Utility Model Content
