The reason why the "notch" at the top of the screen did not disappear even on the iPhone 13, and the potential of the AR technology that appeared

The long -awaited "iPhone 13" series was announced, and this time many options were prepared.Among them, the iPhone 13 Pro and the iPhone Pro Max are the perfect models for film masters who can shoot high -quality videos.It may be true.The "iPhone 13" and "iPhone 13 Mini" are equipped with a larger battery than the previous model, and has a sensor shift -type camera shake correction function that was previously installed only on the most expensive model camera.

But all models have something in common.It is a notch (the protrusion at the top of the screen).We have been hoping every year that Apple will remove the "relics" for about five years and make the "Super Retina XDR display" a full screen.It's just like an organic EL display of Samsung's high -end smartphone.

According to a recent survey by the Apple Information Site "9to5mac", Apple fans' opinions are almost equally equal to whether Apple should maintain a notch or a punch hole type that puts the camera in a "hole" like other companies.It seems to be separated.Some 9TO5MAC readers point out that notch has a unique appearance to the iPhone.

There are also opinions that in this new era when masks began to be worn, the face recognition system "Face ID" should be completely abolished.However, as of September 2021, the number of masks has decreased.

But some of the changes in the iPhone 13 also indicate that Apple also regards notches as "unavoidable compromise products."This is because the notch area has been reduced by about 20 %.

Will it be replaced with a punch hole?

The difference is that it cannot be determined unless you look closely at the iPhone 12 and the iPhone 13.Only in comparison will notice that the width of the notch has clearly narrower than before.On the other hand, the area that can be used for apps and games is narrow due to the slightly thicker notch's depth and biting into the screen side.

It's a moment when you want to look up to the heavens.The phrase that the notch size is "20 % smaller" is noticeable, and the iPhone is not approaching the Android smartphone punch hall type display.

The problem is that Apple cannot replace the notch with a punch hole in any case.This is because the notch has various functions other than the camera.

Conventional iPhone with notch is equipped with the following parts:First, the front camera for self -portraits, environmental optical sensors, speakers, microphones, melee sensors, throwing illuminations, dot projectors, and infrared cameras.

Even if Apple placed the speaker and microphone around the top of the screen, it would not be enough for a punch hole.It is necessary to put a small black space on the display on the display side.

A deep relationship between notch and Face ID

These parts are indispensable for Face ID to work.The throwing illuminator irradiates the invisible infrared rays on the face.The dot projector projects thousands of infrared dots on the face.The infrared camera recognizes the patterns created by these dots, that is, the outline map of the face learned by the iPhone, and determines whether the subject is in a bright place or in a dark room.
