On June 28, vivo displayed a number of displays of invisible fingerprint identification+DSP photography technology jointly developed with Qualcomm at MWC Asia 2017. Among them, invisible fingerprint identification is the "offline fingerprint identification" that has been wildly rumored before. Vivo named it "invisible fingerprint technology", which is the first mobile phone brand in the world to master invisible fingerprint identification.
Vivo showed two solutions at the scene, one of which is the long-awaited "fingerprint identification under the screen", which uses ultrasound to identify room temperature beyond OLED screens and glass. However, because it is still an engineering demonstration machine, the speed of fingerprint entry and identification needs to be improved.
The other display machine uses the invisible fingerprint integrated into the rear of the machine body, and the corresponding unlocking action can be completed by touching the part integrated with "invisible fingerprint technology". In the current display machine, the model with invisible fingerprint identification on the back is faster than the display machine with "fingerprint identification under the screen" in recognition speed. Now let's look at a live demonstration video:

Because this technology can integrate fingerprint identification into the body without opening holes, manufacturers can have more room to play in the design of full screen mobile phones.
In addition to improving the integrity of the body, the "invisible fingerprint identification" also uses ultrasonic technology to complete the task of unlocking underwater, which is highly practical and can solve the natural defect of traditional fingerprint identification in waterproofing. Its demonstration effect is introduced in our demonstration video. More relevant parameters: Qualcomm Announces Advanced Fingerprint Scanning and Authentication Technology
In addition, vivo demonstrated the use of a new built-in independent DSP processor in cooperation with Qualcomm, which contains up to 256MB of operating memory.
The independent DSP processor can independently process multiple frames and synthesize RAW files to provide higher quality, backlight and better night view photos.

An X9s Plus equipped with a new independent DSP processor was also provided for demonstration. We used the iPhone 6s for simple comparison. In this set of contrast samples, the iPhone 6s are overexposed to improve the overall brightness of the image, while the X9s Plus, which uses an independent DSP processor, has better color and exposure control, and the overall image appearance and detail retention are much better. However, the specific imaging performance is still waiting for the launch of models equipped with Qualcomm independent DSP processors.
In addition to making breakthroughs in "invisible fingerprint technology" and independent DSP processors, vivo has also further strengthened the home guard's Hi Fi technology. It has customized a new DAC decoding chip and ear amplifier technology with Qualcomm. Officially, it can significantly improve the sound quality signal-to-noise ratio, dynamics, distortion and output power, but it has not provided specific parameters.
Vivo showed a new machine based on Xplay6+customized DAC on the spot, and showed a new ear amplifier. However, since audio belongs to the field of "metaphysics", the specific performance also needs to wait until the models equipped with new customized DAC decoding chips come into the market. However, Vivo's achievements in the audio field will not disappoint us.
