Ashish Narsale/Rediff.com explains what a notch is and lists some top selling notch phones
How many times have mobile phone enthusiasts heard the word 'notch'?
Yes, I am talking about the distracting black patch at the top of your phone screen. While the general perception is the notch trend began with Apple's iPhone X, I would beg to differ.
The first ever smartphone to come with a notch was the Essential PH-1 manufactured by Essential Products, the company founded by former Android Inc co-founder Andy Rubin.
The Essential PH-1 was announced in May 2017, four months ahead of the iPhone X launch.
Which begs the question: what is the notch?
In order to reduce the bezel at the top of the phone, which holds essential sensors, and increase screen space, the bezel is shrunk to its centre into a notch.
In other words, the notch is the space at the top of the screen provided to hold essential sensors such as the front camera, light sensor, earpiece, proximity sensor, etc.
Ever since the race to build a bezel-less phone has begun, the bezel size is getting narrower.
Samsung has almost removed the bezel from the left and right side of the phone with its edge display or what Samsung calls the Infinity Display.
The fingerprint from the bottom of the screen is moved to the phone's rear so that the display gets stretched right till the bottom.
Similarly, the iPhone X too has got rid of the fingerprint scanner completely.
But the top bezel -- where the front camera, earpiece and sensor reside -- still poses a challenge.
While some brands trimmed the bezel as much as possible, some tried shrinking the components to the centre creating a notch at the top of the bezel.
Thus, the technical limitations to build a phone with full screen display led to the creation of a notch where the camera and other sensors could be placed.
Since then we have seen many phone brands like Oppo R15, Huawei P20 Pro, OnePlus 6, Lenovo Z5, Vivo X21 UD, LG G7 ThinQ, Xiaomi Mi 8 and Asus Zenfone 5z embracing the notch.
Users may like or dislike the notch design but, as the list above shows, many top phone makers are sticking to the notch.
A few days ago, we did see Vivo and Oppo try to solve the problem by introducing their Vivo NEX series and Oppo Find X respectively, but they had to make a few sacrifices on the way.
Both the phones have edge-to-edge display without having the notch and all the essential sensors which reside on the notch are hidden under the display or slide out of the phone's body.
Moving parts in any phone are unwelcome as they open themselves to wear and tear.
Right now, the tech is in its nascent stage but is innovating rapidly.
Here are a few popular phones that have incorporated the notch in their design.
