Abstract

The invention provides a color-changing film, a preparation method thereof, a shell and electronic equipment. The color-changing film comprises a first film layer; a plurality of elastic particles; the plurality of elastic particles are arranged on one side of the first film layer at intervals, and the plurality of elastic particles have a first color; the second film layer is arranged on the sides, away from the first film layer, of the elastic particles; when the plurality of elastic particles are in a first state, the orthographic projection area of the elastic particles on the first film layer is a first area S1, and the color-changing film shows the first color; when the plurality of elastic particles are in a second state, the orthographic projection area of the elastic particles on the first film layer is a second area S2, the color-changing film shows a second color, 25 < = S1: S2 < = 100, and the second color is different from the first color. The color-changing film provided by the embodiment of the invention has a color-changing effect and is low in preparation cost.

Description

technical field [0001] The present application relates to the field of electronics, in particular to a color-changing film, a preparation method thereof, a casing and electronic equipment. Background technique [0002] The color of the appearance of current portable electronic devices such as mobile phones and tablet computers is mostly fixed, and the appearance tends to be homogeneous. There is no color changing function, and users are prone to aesthetic fatigue, which seriously affects user experience. Contents of the invention [0003] In view of the above problems, the embodiments of the present application provide a color-changing film, which has a color-changing effect and is low in production cost. [0004] The embodiment of the first aspect of the present application provides a color-changing film, which includes: [0005] first film layer; [0006] A plurality of elastic particles; the plurality of elastic particles are arranged at intervals on one side of the f...
