You must have doubts about a full screen. When the real machine comes to hand, it is a special-shaped screen or a water drop screen. It is difficult to buy a full screen. And the thick bottom border is conspicuous. Why do businesses promote full screens cannot do the “real” full screen in consumers’ hearts?

The hardest part of the full screen is the integration of the screen. Front earpiece, camera, fingerprint identification, etc. All these need the whole industrial chain to push forward at the same time. The full screen tests the design of various manufacturers in the mobile phone terminals. After all, the screen takes up a large amount of space. The internal design is compact. The design and size of various components are important. This is why some businesses like to reduce the battery content.

The arrival of full screen has had a great impact on the entire industry chain. When designing a full-screen mobile phone, It faces corresponding technical challenges in design. Such as the front panel, camera, earpiece, antenna design, software UI, fingerprint identification, process design, optical distance sensor and other aspects.

In fact, the idea of unlocking the screen fingerprint has long been put forward. But there are many technical difficulties to achieve this function.

It will take some time for the arrival of the “true full screen”. When our technology matures, businesses will break through the technical difficulty of the “true full screen”. Let’s wait and see.
