On September 26th, Vivo held a media communication session with the theme of “Extraordinary experience of square inch fingertips”. vivo announced the latest technology upgrade on the fourth generation of photoelectric screen fingerprints. “Screen Fingerprint DSP Acceleration Technology” “. This technology combines the deep optimization of the SoC platform to achieve a 30% significant increase in the unlocking speed of the Vivo X23‘s screen fingerprints under low-temperature dry fingers and direct sunlight. It is reported that the technology will be carried on the vivo X23 for the first time and will be officially launched online in October.
Wang Xiaojun, vice president of hardware development at vivo, introduced at the meeting that vivo designed an independent processing unit for the fourth generation of photoelectric screen fingerprints, which was undertaken by Qualcomm Hexagon DSP and trusted execution environment.
Tim Yates, Senior Director of Product Management at Qualcomm, also attended the conference to interpret the AI? features supported by Qualcomm Snapdragon 670. He said that the performance of the Snapdragon 670 is 1.8 times higher than that of the Snapdragon 660. At the same time, because of the processing of neural networks and fingerprint data, the DSP can significantly increase the processing speed compared with the CPU, resulting in seamless and secure fingerprint unlocking. Experience. Tim Yates said that the Hexagon DSP and Trusted Execution Environment together deliver up to 3x faster speeds than using a trusted execution environment alone.
It is understood that this is the first technical cooperation between Qualcomm and vivo for the screen fingerprint technology.
At the communication meeting, vivo said that the “screen fingerprint DSP acceleration technology” enabled the X23’s screen fingerprint to achieve a 30% significant increase in the unlocking speed of “drilling scenes” such as low-temperature dry fingers and strong direct light. “Screen Fingerprint DSP Acceleration Technology” will be officially launched on the vivo X23 in October.
The vivo X23 mobile phone was released on the 6th of this month. It was upgraded to the fourth-generation photoelectric screen fingerprint unlocking technology. In the sensor hardware specification, the X23 uses F/1.5 large aperture and 720dpi ultra-high resolution fingerprint sensor. Large, clearer imaging, providing excellent hardware protection for higher recognition rates and faster unlocking speeds.
The Vivo X23 unlock speed is 40% higher than the X21. The official said that it only takes 0.35 seconds to unlock in the bright screen state.
In January of this year, vivo released the world’s first screen fingerprint technology mobile phone vivo X20 Plus screen fingerprint version, followed by March, vivo also appeared in the APEX mobile phone supporting half-screen unlock, but it is not clear when the technology is large-scale Mass production.
In the communication meeting, vivo also showed a small muscle – in the long-term investment and research and development optimization of the screen fingerprint field, vivo has applied for 140+ items related to software and hardware.
