Abstract

The present invention relates to the field of electronic equipment. A preparation method of a housing comprises the following steps of processing chamfers and / or rounds on first edges of a housing opening, and forming first narrow edges; forming a protection layer on the housing body, and performing first coloring on the first narrow edges; processing chamfers and / or rounds on second edges of the housing opening, and forming second narrow edges; and performing second coloring on the second narrow edges and the housing body. The preparation method of the housing is simple in process, the accuracy requirement is low, the visual effect that edges of a screen are free of frames when a portable electronic device is viewed from the front side can be achieved, and a series of related tests of the whole machine can be satisfied due to the fact that the housing has the narrow edges.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a casing and a preparation method and application thereof. Background technique [0002] With the continuous development of science and technology, the use of smart phones has become more and more extensive, and has occupied the mainstream position in the market at present, and is a necessary configuration for people's daily work and life. Due to its extremely high usage, people have higher requirements for it, not only pursuing the intelligence of mobile phones, but also pursuing the ultra-thin and narrow-edge design of mobile phones. [0003] At present, in order to improve the user's viewing experience, the screen of the mobile phone is getting bigger and bigger, but the larger mobile phone screen and the frame not only limit the design of the mobile phone product, but also are inconvenient to operate and carry. Extremely narrow bezel design or even "bezel-less" design can...
