Vivo is the first and only company that has demonstrated both "ultrasonic" and "optical" fingerprint testing machines under the screen:
Vivo used Xplay6 as the prototype in MWC in 2017, equipped with Qualcomm's ultrasonic fingerprint technology under the screen. The advantage of this scheme is that it has strong resistance to obstacles and can identify underwater, but the fingerprint identification speed of the tester was slow at that time;
In the CES in 2018, vivo uses vivo X20 Plus as the prototype, which is equipped with Synaptic's optical fingerprint scheme under the screen. The sensor model is Clear ID FS9500. The principle of photoelectric fingerprint recognition is that when the user's finger is pressed on the screen, the screen will light up, and its blue-green light will shine on the fingerprint for reflection. After reflection, the sensor in the fingerprint will take a picture of the finger like an image to match the fingerprint.
Everyone thinks that the mass production of the screen fingerprint engineering machine will take some time, On January 22, vivo official WeChat and WeChat enterprise account pushed the message of vivo X20 Plus screen fingerprint version. The copywriting is simply "the first mobile phone with screen fingerprint! # X20Plus screen fingerprint version # Surprise is coming, and we will start a new experience with you." In fact, it has been exposed on the Internet since last week. The model of the machine is vivo X20 Plus UD, and the price is 3998 yuan. The launch date is January 25.
Ordinary capacitive fingerprint includes front fingerprint and back fingerprint. In the previous interview, Vivo said that the current fingerprint scheme under the photoelectric screen costs 3-4 times more than the front capacitive fingerprint scheme. However, if the new model is really 3998 yuan, and the price is only 500 yuan more than that of the regular version of the vivo X20 Plus, it is still more conscientious.
Officially released at 7:30 p.m. on January 24
