Abstract
The invention relates to the field of electronic equipment and discloses a preparation method of a shell. The method comprises the following steps that the edge of an opening of the shell is subjected to chamfering and/or rounding to form narrow sides; a protection layer is formed on the second narrow side and a shell body, and the first narrow side is subjected to primary coloring; and the protection layer is removed, and the second narrow side and the shell body are subjected to secondary coloring. The preparation method of the shell is simple in process and low in precision requirement, and the visual effect that the edge of a screen is not provided with a frame when a portable electronic device is seen from the front can be achieved. In addition, due to the narrow sides, a series of relevant tests on a complete device can be achieved.
Description
Technical field
The present invention relates to electronic device field, be specifically related to a kind of housing and its preparation method and application.
Background technology
Along with the development of science and technology, the use of smart mobile phone is more and more extensive, already takes up at present
