Problems solved by technology

[0002] With the development of communication technology, smart phones are becoming more and more popular, and the functions of smart phones are becoming more and more powerful. The main board structure, the battery is installed in the back cover, and various components and conductive lines connecting the components are distributed on the main board of the mobile phone. To take out the battery of the mobile phone, the back cover must be lifted completely, which is extremely inconvenient
Moreover, the electrical components arranged on the main board body are easily disturbed, which affects the influence of the main board of the mobile phone. At the same time, the color of the existing LCD display screen is not rich enough
