By Carrie Tsai, Last Updated: February 15, 2020
Since the first-ever one-curved edge screen Galaxy Note Edge was launched in 2014, the curved screen has been all the rage. Without a doubt, it's one of the best developments in smartphones in the past few years. Under the trend, more and more phone manufacturers have launched or are launching their curved screen smartphones to complete in the market nowadays. But at the same time, flat screens are also developing with the move towards full screens.
So the question arises, that if smartphones with curved screens are worth it or not. Curved vs. flat screen, which one is preferable? In order to figure out the question, here comes the comparisons. That is, to understand the differences between these two kind of screens. The following is going to list some differences between the curved screen and the flat screen by comparing different factors.

Price
Curved screens are much more expensive than the same level flat ones in the current smartphones market. For instance, Samsung Galaxy S10, a smartphone with curved screen, is at a price of $899.99 which is higher than the price of other flat screen Samsung Galaxy smartphones. Curved screens are at higher prices due to their higher production cost. This is because producing a curved screen is much more difficult, leading to more costs in production.
The good new is that curved screen smartphones are getting more and more cheaper and closer to the price of flat ones with the market saturates. Nevertheless, the flat screen is much more preferable on price compared with the curved one.
Appearances
The most obvious difference between the curved screen and the flat screen is their outer looking. Different from the flat ones which are flat in all directions, the curved screens usually have one-curved edge or dual-curved edges. They are so much better looking and gorgeous than the flat ones and greatly increase the aesthetics of smartphones.
Moreover, thanks to the curved edges which make the surface area of curves larger than that of a flat surface, smartphone manufacturers are able to fit a wider screen in a shorter overall width.
Building Material
Different from flat displays with normal rigid LCD panel, the curved screen is made from flexible plastic OLED materials. With non-rigid glass on the surface, the curved screen is more elastic and not easy to break, leading to less screen wear especially while being touched. In this way, compared to a straight screen one, the curved screen smartphone seems to be what you should chase for.
Nevertheless, OLED materials face the challenges of instability and short life due to the juvenility of OLED technology. At this point, the curved screen is less practical than the flat one.

Viewing Experience
One of the most noticeable advantages of curved screens on smartphones over flat ones is the better visual effects they can bring to users. Their curves on the side provide excellent 3D viewing experience. In addition, they also bring better overall image quality, improved contrast and color accuracy. Furthermore, they increase smartphone readability in ambient light. This is because a curved screen blocks other light and also reflects its own light better than a flat one.

Power Consumption
Considering power consumption, the curved screen seems to overshadow the flat one. A flat smartphone display is in need of more brightness because of its high strength of screen reflections, which causes more power consumption and shorter battery life. However, the curved screen is conducive to less power consumption and longer battery life. This is because its outer design greatly reduces visible reflections and brightness.
Screen Privacy
All the time, screen privacy leak problem exists in smartphones with flat screens. Flat screen users always complain that the contents on their screens could be easily seen or pried by others nearby due to high visible reflections.
Different from the flat one, the unique curvature of the curved screen prevents other people from viewing what's shown on the screen by blocking vision from the side, which improves screen privacy greatly. In addition, as mentioned earlier, the curved screen greatly reduce visible reflection, which avoids broadcasting the images on your screen to people near you. At this point, the curved screen seems to be more humane than the flat one.

Extra Cool Functionality - Edge Lighting
Edge Lighting is a new feature of curved screen smartphones which is exactly what flat screen ones don't have. It's available due to the curved edges in the corner of the curved screens. There comes no questioning that Edge Lighting is powerful and practical since notifications which can alert you such as phone calls and text messages are shown on it.
This new feature becomes one merit of the curved screen smartphones, which could affect the purchasing intention of consumers. Especially for phone users who are obsessed with novel features, this new feature could be the catalyst of users'decision of choosing the curved screen rather than the flat one.

Dropping and Breaking Risk
Compared with the flat screen smartphones, although the curved screen ones look gorgeous and have many cool functionalities, they are more fragile and less durable since they are more prone to drop and break.
The reason why they are inclined to dropping and breakage lies in their edges. On the one hand, the curved edges of curved screen smartphones are thinner, which makes them difficult to grip and in turn prone to dropping easily. On the other hand, more fragile glass areas in the margins increases the chance of cracking once the phone collides or drops.
However, smartphones with flat screens don't have the curved surfaces at the edges, which makes them less fragile and easy to hold tightly. Whether a screen is durable and resistant to drop or not can really affect the buying decision of phone consumers. After all, the majority of people will not choose to buy a phone with cool functionalities at the expense of durability.

Accidental Touches
Although the curved screen on smartphones is filled with lots of advantages, they still cannot work well sometimes due to accidental touches on the edges with the palm. While gripping the phone, it's easy to accidentally touch the edged displays where there are usually apps and phone tools. This can easily cause phone running issues. However, this problem will not exist while using flat screen ones since there are no edged displays on them.
Repair cost
As mentioned earlier, as compared to flat screens, the building material of the curved screens on smartphones is flexible OLED which is much more expensive and difficult to make. Therefore, their repair cost is much higher then flat ones. Moreover, the replacement of a curved screen is much more challenging than a flat one, which also increases its replacement cost.
Conclusion
From the above listed differences, I guess you can make better comparison of the curved screen and flat screen. In the fast developing information era, technologies in smartphones are emerging endlessly. Whether from flat to curved to full screen, making overall comparisons and trade-off before deciding whether to buy one is of great necessity. Hope you enjoy this article.
