Vivo has introduced a new Under Display Fingerprint Scanning Solution during the Mobile World Congress (MWC) Shanghai 2017. Vivo UnderDisplay is a new fingerprint unlocking solution which utilizes built-in ultrasonic technology beneath the screen to realize fingerprint recognition in a more complete way, results faster & efficient smartphone unlocking regardless the screen condition. In conjunction of that, the brand has also introduced Digital Signal Processing (DSP) Photography Solution targeted for backlighting and night scene photography, and a Hi-Fi solution with a customized DAC decoding chip.

Independent DSP Photography Solution: Greatly improve backlighting and night scene photography

To improve photo quality in complicated lighting conditions such as low-light and backlight environments, Vivo is introducing its brand new independent DSP Photography Solution.

In day to day mobile phone photography, users might experience various complicated lighting conditions. The Vivo DSP Photography Solution is designed to help users take pictures with high quality and accurate exposure, and adjust the brightness of the image to make it better correspond to what is actually seen by the human eye. The photography processing speed has also been greatly enhanced.

Moreover, DSP photography solution allow taking multiple RAW pictures when shooting under complicated lighting condition and the DSP chip will then automatically process and compose a single RAW picture, which is then exported to JPG format by ISP. This will, theoretically, improves the overall quality of the image. Apart from a higher processing speed, the DSP Photography Solution can reduce shot noise for night scene photography to a large extent and even improve the beautification effects of Vivo's Face Beauty Mode.

New heights for smart phone Hi-Fi audio: new customized DAC decoder chip and headphone amplifier technology

Hi-Fi refers to High-Fidelity audio, and products equipped with this technology can provide the users with a high-quality music experience.

As the pioneer of Hi-Fi in smartphones, Vivo has established its position in the mobile phone audio industry through generations of products, and even has promoted the development of the audio chip industry. After bringing smartphone Hi-Fi audio to a new level with its Xplay6 phone, Vivo is releasing a new Hi-Fi solution with improved audio performance from a customized DAC decoding chip.

The new solution is focused on perfecting details via a customized DAC decoding chip together with a customized headphone amplifier, which improves SNR, dynamic range, distortion, and output power. It surpasses the high-quality audio experience of the Xplay6 with an SNR of 122dB, dynamic range of 120dB, distortion of -111dB, and output power of 2.2VRms.

The solution has twice the output amplitude as ordinary phones. In subjective acoustic evaluations it has shown better resolution and thrust, rich details, and strong spatial perception. Moreover, the headphone amplifier utilizes new processing technology to improve power efficiency as well as the overall audio experience.

[center]In-depth Sneak Peek on the Vivo Technology which Surpass Apple & Samsung – Under- Display Ultrasonic Fingerprint Unlocking!

In the early of June, we have been hearing a brand new technology that will crashes on the smartphone market - Under-Display Ultrasonic Fingerprint Sensor. Currently, under-display ultrasonic fingerprint technology has not been released in the world. However, over 445,000 topics concerning “under-display fingerprint sensor” have already appeared across the net. Meanwhile, on social media as well as traditional media, “under-display fingerprint sensor” has also leads to a global tech savvy’s attention. Rumor has it in the industry that iPhone 8, which going to launch such technology during September. Once iPhone employs ultrasonic fingerprint technology, it will soon become the mainstream fingerprint recognition solution. In this context, working together with Qualcomm, Vivo will be one of the first brands to introduce under-display ultrasonic-based biometric fingerprint technology.

Vivo Under Display (abbr. Vivo Under Display Fingerprint Scanning Technology) is jointly launched with Qualcomm. It is a new fingerprint unlocking solution which utilizes ultrasonic technology to realize fingerprint recognition. It is the industry’s most advanced fingerprint unlocking solution at the moment. Because of the high penetration ability of ultrasound, Vivo Under Display can realize soft-screen OLED fingerprint recognition, which is conducive to an integrated unibody phone design. Compared to traditional capacitive and optical fingerprint recognition technologies prevalent in the industry, Vivo Under Display does not lose its accuracy with wet fingers and in other conditions. Based on ultrasonic technology, Vivo will continue to research underwater fingerprint unlocking, gesture recognition, bioinstrumentation and other fields, and launch even more advanced recognition technologies.

Highlight Features

Stronger Penetration Capacity: Ultrasonic fingerprint recognition technology can solve the issue of penetration depth which limits current traditional capacitive fingerprint technology. The traditional capacitive recognition has a weak penetration capacity (penetrating 300um of glass at most). Vivo Under Display can penetrate more depth and more materials, such as 1.3mm of OLED, 800μm of glass, or 525μm of aluminum.
Even Better User Experience: In terms of waterproofing, dust-proofing, and reducing ambient light interference, this technology is in a relatively advantageous position compared to other fingerprint technologies. Compared to optical fingerprint solutions, Vivo Under Display is not affected by ambient light, and can work in more situations. Compared to capacitive fingerprint solutions, Vivo Under Display is relatively less affected by water marks or sweat marks, and has better accuracy with wet fingers and in other conditions, offering a much better user experience.
1. Benefits to Phone Design: Because of Vivo Under Display’s strong penetration capacity, it can ensure a phone body design without holes or divisions to realize OLED under-display fingerprint recognition. This can in turn help with future phone designs - infinity screens and integrated unibody design.
2. Benefits to Mechanical Waterproofing: Because no holes are required, a structural waterproofing design can be realized, minimizing the environmental restrictions in terms of phone usage.

In addition to Vivo Under Display, Vivo has also realized water resistant technologies for smartphone. The best waterproof phone has become a necessity in 2017, whether you’re accident prone or just a bit paranoid. It can put your mind at ease knowing your expensive new smartphone can withstand a dunk in the pool or a spilled drink at the pub. Combined with an integrated waterproof design, underwater unlocking, underwater photography and other activities are made possible to vivo smartphone.
Moreover, thanks to ultrasonic technology, the fingerprint recognition technology can also be further expanded to realize user interaction, such as gesture recognition (recognize gestures and implement the commands through finger swipe in the fingerprint sensor area, security verification and other fields, greatly enhancing the user experience.
