Every day a new technology pops up, and the entire market gets an upgrade. Smartphones are one of the most trending product markets in the world, and even the smallest innovations get a tremendous response from the customers. One of such technologies is the fingerprint sensor which was first introduced as a revolution by Apple Inc. in their iPhone 5S, and since then the technology has taken different shapes, and a surfeit of smartphones are available in the market with all sorts of additional features.

In 2019, the manufacturers took another step towards innovation and introduced under-display fingerprint sensors. It is the next big thing in the market along with notch feature, which is attracting more audience as both the features combined offer a full display which suits the taste of the users. But is the under-display fingerprint sensor really a need or it is just a fancy technology to gather more crowd. Let us look at the advantages and disadvantages to understand it better.



Having a fingerprint sensor at the backside is pretty common in smartphones. The under-display sensor provides the touch of future as well as adds to providing a better look for the back panel.

The under-display sensor also feels more natural and is much more convenient to use while holding the phone on hand. It does the work of using the phone at ease without taking any unnecessary space on the phone. As it is not visible, it helps in making the phone look neater than the other smartphones.

Having a fingerprint sensor at the back also put in the effort to pick it up from the table for unlocking. Other than than, the fingerprint sensor under the display can have more area to use as compared to centimetre sensors. It is also protective of the grease and water as the sensor is not exposed and is buried under a glass screen.


The main con of under-display fingerprint sensor is that both optical-type and ultrasonic sensors are slowers than the capacitive ones and also have a higher error rate. They are also dependent on the functionality of the display and gets slower over time as the device gets old.

The cost of repairing can also be a disadvantage as the damage to the screen can also cause the sensors to malfunction and can cost additional money.
