Hello dear Tecnogalaxy readers, today we will talk about the smartphone with the camera under the Google display.

Smartphone makers have invested heavily in reducing bezels in recent years in order to create a beautiful edge-to-edge display. However, this poses some challenges, particularly as there is too little space to integrate the front camera and sensors into the frame. Currently, a perforated camera system is widely used, a small hole in the screen to accommodate the selfie camera.

The next step is the under-screen camera, as ZTE has already implemented with the Axon 20. Several phone manufacturers are expected to release their first smartphone with an under-screen camera this year, including Samsung, Xiaomi and Oppo. However, this new technology is not that easy to apply, without compromising image quality. Google has come up with an ingenious solution, according to a new patent.


In mid-September 2020, Google LLC filed a patent with the World Intellectual Property Organization (WIPO). The 23-page documentation titled “Full Screen Display with Sub-Display Camera” was released on May 6, 2021 and describes a Google Pixel smartphone with a front camera built under the screen.

The documentation mentions a Google phone with an OLED display. The front camera is positioned below the screen. To make this possible, an additional display panel is integrated, an OLED panel with the same pixel density will be used for this.


This is not the first time that we have reported the integration of a secondary display to support the camera technology under the screen. Earlier this year, Samsung filed a similar patent. However, Google wants to integrate this auxiliary display in a different way.

The camera sensor and lens are positioned under the screen. The second screen is placed directly in front of the camera, it is located below the main screen. A prism or mirror is placed between the camera and the auxiliary display.

When the camera is not in use, the content displayed on the second screen is reflected through the prism on the main display. As soon as the camera is activated, the prism rotates so that incoming light can reach the camera, allowing the user to take high-quality photos and video recordings. The optical module is shielded by a window of approximately 2-3 mm in size, according to the documentation.

The small auxiliary display also contains three sensors. The type of sensor can be further determined, such as an environmental sensor, a proximity sensor and / or an IR sensor. The latter can be used to enable 3D face detection.

With the Google Pixel 5, Face Unlock has been omitted to make way for a fingerprint sensor. However, it was indicated at the time that Face Unlock may return in future models.


For the moment, it is unclear when the first Google smartphone with an under-display camera will be announced. It was briefly speculated that the Google Pixel 6 (Pro), expected in the second half of 2021, will have a new type of selfie camera.

Recently, however, the first product renders of this device have appeared online, showing a perfect camera system. This could mean that we need to be patient until 2022 when the Google Pixel 7 series is introduced.

However, there is another option. In December last year, display analyst Ross Young reported via Twitter that Google will unveil its first foldable smartphone in the second half of 2021. Details on this device are still very scarce, but Google may see an opportunity to equip its foldable phone of this new camera technology.

In any case, there doesn’t seem to be the question of whether Google will launch a smartphone with an under-screen camera, but when …

That’s all, see you in a future article.
