On September 7th, Meizu Li Nan published an article entitled "Don't argue, Samsung S8 is the real full screen" in Zhihu, and talked about his understanding and views on "full screen".
In response to the concepts of "Lei Jun: Xiaomi's first full-screen in the world" and Xiaomi MIX2 "Full-screen 2.0", Nubia and Sharp released posters one after another yesterday. The copy of Full-screen 2. 1 and Full-screen 29.0 is obviously aimed at Xiaomi. Unexpectedly, this stalk has caused a spoof carnival of netizens. ......
Overnight, Huawei Full Screen 3.0, Hammer Full Screen 9.0 and even the nonexistent "Perfect Mobile Phone Full Screen 10.0" came, but the most classic is the spoof of this LeTV mobile phone: Full Screen +∞, yes, we still have money to make mobile phones.
Various concepts and arguments about full screen will continue. With the release of products from various manufacturers, the gap between posters and actual products will be seen by everyone. But there is no doubt that 20 17 is the year when full-screen mobile phones broke out, which will also lay the foundation for mobile phone design languages in recent years. Faced with the current design of full screen, manufacturers need to face many problems: for example, the integration of full screen is not high, it is difficult for sensors to avoid opening holes, and it is difficult to choose between front fingerprint and full screen ... Some of these problems have been compromised, and some have already made some choices.
Now let's analyze what are the problems under the comprehensive screen, and what compromises and trade-offs have been made for these comprehensive solutions now in front of us (the technical side is racing).
Ideal full screen
Literally, the full screen means that the front of the mobile phone is full of screens, and the four border positions of the mobile phone are borderless, and the screen ratio is close to 100%.
Mobile phone in reality
As we can see from the picture, our mobile phones now have:
Top: receiver, sensor, front camera
Left and right: borders and buttons are all done to the extreme.
Bottom: fingerprint, charging data interface, earphone interface, speaker.
If you want to realize the ideal full-screen mobile phone, these must be solved or abandoned through new technical solutions.
Let's take a look at what solutions have been released by these full-screen mobile phones, and what compromises and trade-offs have been made.
The first kind:
This scheme is not much different from the current mobile phone:
The upper and lower parts are further compressed, and the full screen of 18: 9 is adopted under the condition that the external outline size is basically unchanged.
In order to reduce the size of the bottom, the front fingerprint compromised and changed to the rear fingerprint.
The second type:
This scheme further compresses the top size through a special-shaped all-in screen:
The front camera at the top is still retained, and the receiver and sensor can be compressed and put together with the front camera, or can be replaced by other schemes.
The bottom is basically retained, and the pre-fingerprint compromise is changed to the post-fingerprint.
The third kind:
This scheme will basically reach 100% at the top and left and right sides:
Top: the receiver adopts bone-to-bone or ceramic acoustic system; Sensor: adopt ultrasonic sensor or TP contact induction; The front camera compromised and put it at the bottom instead.
Bottom: The bottom is basically retained, and a front camera is added, and the front fingerprint is compromised and changed into a rear fingerprint.
The fourth kind:
This scheme will realize left and right 100% visually through the curved screen:
Left and right: through the curved screen, the left and right will be 100% visually.
The top and bottom functions are retained, the size is further compressed by device optimization, and the pre-fingerprint is compromised to the post-fingerprint.
The fifth type:
In this scheme, the bottom and left and right sides are basically 100%, and the size of the top is further compressed by a special-shaped full screen:
Top: the receiver adopts bone-to-bone or ceramic acoustic system; Sensor: adopt ultrasonic sensor or TP contact induction; The camera is still there.
Down: Use off-screen fingerprints or other unlocking methods.
(Note: However, judging from the current liquid crystal devices, it is impossible for the bottom to approach 100%.)
At present, there are many problems that the full screen needs to face, such as the low integration of the full screen, the difficulty in avoiding the opening of the sensor, the inability to give up the front camera, and the difficulty in choosing between the front fingerprint and the full screen.
