Background
With the development of society and the continuous progress of science and technology, the requirements of people on the display screen of the mobile phone are higher and higher. The mobile phone screen is larger and narrower, and the trend of pursuing a full-screen mobile phone with a screen ratio close to 100% becomes mainstream all over the world. But actually, the mobile phone is limited by the current technology, only a mobile phone with an ultrahigh screen ratio is used for the moment, and a mobile phone with a front screen ratio of 100% cannot be used. The comprehensive screen mobile phone is a mobile phone with a screen percentage of more than 90% and an ultra-narrow frame design.
At present, devices such as a receiver of a mobile phone and the like can be made very small and hidden in a frame, but the front camera, which is a commonly used self-photographing function of a user at present, cannot be replaced by other technologies, and the arrangement of the front camera seriously hinders the improvement of the ratio of a mobile phone screen and influences the realization of the overall screen effect.
Meanwhile, due to the defects that the front camera in the existing full-screen mobile phone causes a deformed mobile phone screen such as bang and the like, the deformed mobile phone screen greatly increases the manufacturing process, thereby reducing the yield of the display screen.
