Patent reveals Huawei is working on in-display earpiece technology

Smartphone makers these days are working on new ways to reduce the bezels on phones while increasing the overall area of the display. This has led to smartphone makers using notches, in-display fingerprint sensors and even going back to sliding mechanisms.

While smartphone makers started with a big notch, the feature has now become considerably smaller on devices like the OnePlus 6T, where the company has used a water drop notch design.

Working on the same lines, Samsung recently unveiled its Infinity notch designs at its Developer Conference wherein it will use small notches for the front camera. The designs include Infinity U, Infinity V, Infinity O, New Infinity and the Infinity Flex for the foldable screen.

Huawei is also expected to adopt the Infinity O design for its upcoming P30 series.

Smartphone makers such as Huawei, Samsung and Asus are also working on in-display cameras, which will remove the need for a notch. Now, Huawei has filed a new patent with the United States Patent and Trademark Office (USPTO) where it has used an in-display earpiece, allowing it to reduce the bezels without using a notch.

Earlier, Xiaomi in the Mi Mix and Mi Mix 2 had used a piezoelectric speaker to put the speaker behind the display, however, the sound quality was not as good as regular speakers. With this, Huawei may be able to provide better sound quality without using a notch or big bezels.

The patent has revealed a small and thin hole under the display for the earpiece, however, what's missing from the front is the selfie camera. Either Huawei has placed the selfie camera along with the earpiece or the company might use an in-display selfie camera.

At the back, the device has a dual camera setup and a fingerprint sensor below it, meaning that the device will not sport an in-display fingerprint sensor. At the top, we can see the 3.5mm audio jack and the bottom has a USB Type-C port. The volume rockers and the power button have been placed at the right side.

While companies patent several designs, not all of them are used by the companies. We will have to wait and see if the company uses the device in any of its upcoming smartphones.
