Hole Punch Displays – Are they better than Notch Design?
Now that Honor View 20 is out, it's time to talk about the 'Hole Punch' display concept. Well, before that, let's go back to the point which led to a new design trend in smartphones. On the eve of iPhone's 10th anniversary, Apple released its 10th iteration, iPhone X, with an arguably highest Screen-to-Body ratio in any iPhone. It was all possible because of the NOTCH at the top. Since then, several smartphones have copied, modified, and changed the design of smartphones forever. I always believed in one thing, and it proved all along.

3. So, Is Hole Punch Display Better than Notch?
If Apple launches something and calls it innovation, I bet several Android OEMs will copy or re-create it. It's been proved with the 'NOTCH' adoption.
Since 2016, with the introduction of Mi Mix to the market, OEMs have started focussing on reducing the bezels to give a higher Screen-to-Body ratio. At the end of 2017 [September], with the introduction of 'Notch' on an iPhone, it went viral and ultimately got wider adoption. The same thing continued in the last year as we've seen a flood of phones with [ugly] notches [yeah, I mean Pixel 3XL]. Some brands even went further and compared the dimensions of the notch, which in their case was tiny compared to iPhone X's.

What is the Display 'Notch'?
The notch on a smartphone is to house the selfie camera, speakers, and the necessary sensors. The rest of the edges can give information such as time, signal strength, a couple of notifications [icons], etc. Now here comes a question – what about the viewability and UX? Several Tech Pundits [and a few OEMs] gave an absolute statement saying you'll eventually get used to it, and in fact, you won't even notice it.
So, was the trend continued? Let's find out in the types of notch displays –
Types of Notch Display Phones
As far as the trend goes, there're observably 5 types of notch display phones that exist now. Let's look at one by one, shall we?
1. No NOTCH Display Phones / Pop-up Camera Phones

When the Apex concept [later released as Nex] showcased at CES 2018, it blew everyone's mind. There was no notch and the front-camera pop-ups from the top, giving enough reasons to like it. From the design aesthetics, it was freaking brilliant, but again, it has a mechanical part that makes it pop up. So, in the long-term, it creates a lot of problems. It's the sole reason why many brands' haven't adopted it yet, but it turns out it's the big design trend in 2019 smartphones. Even the recent V15 Pro, Oppo F11 Pro, and the upcoming OnePlus 7/7 Pro feature a pop-up selfie camera.
The Find X from Oppo took it to another level by keeping a slider at the top. We've seen slider phones in the past, and as the mechanical parts are involved, the phones are less reliable and inefficient. The same thing is applicable to Find X, too. In both these slider phones, there was no NOTCH, and that's one of the main reasons why I liked both. The speaker and the sensors are at the extreme top, but again, the bottom bezels are thick AF.
2. Notch 'O' Display Phones
Before the iPhone X introduced the 'NOTCH,' the first notch smartphone was the Essential Phone, which launched in May 2017. The tiny 'O' notch at the top houses the selfie camera, but it was treated as an eye-soar. Brands' haven't shown interest in the beginning, but with the launch of iPhone X and the wider adoption, some brands [majorily Chinese] announced their Notch 'O' phones. Vivo, Huawei, and Honor were among the top.
On the contrary, the South Korean smartphone giant, Samsung, was never interested in the 'Notch' design, but it's coming with 'M' series this year, which would feature a notch. It even showcased its new design concepts – Infinity U, V, and O last year.
Besides the 'O' notch, brands like Oppo, Vivo, and Huawei have also introduced the waterdrop notch.
3. Water Drop Notch Display Phones
Waterdrop notch is a derivative of 'O' notch that featured in the Essential phone. Compared to all the notch phones, the waterdrop notch phones have got the broader appeal. Smartphones such as Oppo F9 Pro, Vivo V11 Pro, RealMe 2 Pro, Mate 20, etc. features a waterdrop notch.
I liked the waterdrop notch than the traditional notch as the screen real estate is higher, and doesn't appear as an eye-soar.
There's one thing I couldn't understand is 'why smartphone manufacturers couldn't come up with an ideal solution that breaks' the traditional approach? Then began the era of slider phones!
4. Slider Camera Phones
We've already seen this in Oppo Find X and Vivo Nex, but the OEMs took enough time actually to adopt it. One other reason which I feel is the new iPhone Xs Max hasn't shown an innovative design change, so the better way to make phones notch-less is to adopt the slider.

Honor and Xiaomi have already showcased their slider phones with no mechanical sliders, but no one is sure about its reliability. And hey, even the recent Samsung Galaxy A80 has a slider that pop-ups and rotates the rear camera to act as a front-facing camera. That's the combination of Oppo N1 and Oppo Find X.

In my opinion, the OEMs have no choice to adopt this slider Cameras trend as the notches are too mainstream now!

You'd have already noticed the traditional notch design and water-drop even on the budget-end smartphones, so it doesn't make a vast difference introducing a new smartphone with the same top-notch design. So, the best option available now is to adopt a slider or add something more unique, i.e., Hole Punch/Infinity-O.
5. Hole Punch Displays
Vivo has become one of the first smartphone makers to introduce the in-display fingerprint sensors on a smartphone, and now it's widely available on major flagships. Besides fingerprint, everyone's eye is on keeping a camera unit under the display to give an extremely higher screen to body ratio. Well, it's not possible even now, but OEMs like Samsung and Huawei found an alternative.
To keep away from the notch, and at the same time, give enough real estate, Samsung showcased a hole-punch design dubbed as Infinity-O in its Samsung Galaxy A8s. In the picture below, you could see the selfie camera protruding from the display. For achieving this, the hole drilled till the very bottom [surface layer], and the selfie camera embedded inside it. It leads to an unwanted black ring around it.
There's no way you can hide the black ring or cover the selfie camera with pixels. It doesn't go away when watching the videos, and it just stays right there. Get used to it!
One of the significant downsides which I feel here is not only the distraction but also the leakage of light. As the selfie camera is placed right above the bottom layer and covered by the display layers, the light entering in and out won't be the same as in a traditional front cam. So, we can expect not-so-good quality selfies. However, we might need to see the actual camera samples before judging it.
Besides, as there's a hole in the screen, the display is prone to breaking, shattering, etc. I wonder how Samsung is going to justify this.
In the case of Honor –
They were able to fix the problems associated with the hole punch concept [already]. From what I read in XDA, the Honor View 20's selfie camera doesn't fully penetrate in the display, yet gives the same camera function as a traditional smartphone.
Here in the Honor View 20, they used an LCD. With a unique technique called Pixel transition technology, they were able to control the flow of liquid crystals, thereby enabling more light for the camera. It confirms that the screen is also more durable than its competitors' as there are more layers of glass over the camera.
Unlike traditional manual drilling, Honor has adopted Photolithography drilling, which made it possible to keep the aperture as small as possible. Because of this, the diameter of the hole came out at just 4.5mm, whereas, in Samsung Galaxy A8s, it's around 6.7mm. Whichever be the size, even in Honor View 20, you can't cover the camera with the pixels, meaning, it just stays there at the extreme left.
Maybe when the screen is dark [off], you might not be able to notice it, but when the screen lit and you're watching videos, playing games, you'll see it. Nonetheless, the hole punch is the prime solution for the notch-less designs now, and with the official launch of Honor View 20, Huawei opened roads for others' to follow it. Meaning, Huawei became the first OEM to launch a hole punch flagship phone.
So, Is Hole Punch Display Better than Notch?
Whether it's a notch, or a slider or a hole punch display, brands came up with these concepts to give a bezel-free experience. Compared to Notch, the screen real estate is higher in hole punch, but you might feel the same distraction. As of now, the hole punch cameras are the extreme left, meaning the time, notifications, and signal strength indication is right next to each other.
You might also feel a little trouble when accessing the notification bar because you know, Android supports notch, but not the Infinity-O or the Hole punch. Anyway, unless the OEMs come up with a groundbreaking tech that covers the camera with the pixels when not in use, I feel, the design changes are just a temporary solution.
Also, isn't Apple supposed to be an innovative-driver? But now, things are upside down. Should we expect an iPhone with the hole-punch display? Well, we've to wait for the leaks.
For now, you can expect more [a lot] hole punch smartphones to release in the coming months.
Update – It's here. Oppo and Xiaomi showcased their concept phones, which have under-display cameras, which solves the problems associated with the 'NOTCH.' Oppo did show a demo, but it's yet to hit the markets.
