The color changing OLED display screen is embedded onto the upper surface of the mobile communication terminal body, the motherboard is integrated in a cavity of the mobile communication terminal body, the color changing OLED display screen comprises a plurality of compactly arranged color changing OLED apparatuses, each of the color changing OLED apparatuses comprises a heat-dissipating adhesive layer, ITO glass, a hole injection layer, a hole transmission layer, a first light-emitting layer, a first energy transfer regulating layer, a second light-emitting layer, a second energy transfer regulating layer, a third light-emitting layer, an electron transmission layer, an electron injection layer and a cathode electrode which are successively laminated. The mobile communication terminal provided with the color changing OLED display screen has a color changing function and is wide in color regulating range.

Description

technical field

[0001] The invention relates to the field of mobile communication, in particular to a mobile communication terminal with a color-changing OLED display screen. Background technique

[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. Meanwhile, the existing LCD display screens are not rich enough in color. Contents of the invention
