Qualcomm's Ultrasonic Sensor Has Decided to Be Applied to Two Models of Samsung Galaxy S10

Samsung Electronics will apply the off-screen fingerprint identification technology that can be identified even if stained with water or soil on the new generation of strategic smartphone "Galaxy S10". Off screen fingerprint identification technology is a technology that can identify the fingerprint and judge whether it is the user or not on the smartphone screen without other key forms.

The content related to off screen fingerprint identification of Galaxy S10 was uploaded at Qualcomm's new product launch recently held in Maui, the United States. In the event, a sensor for fingerprint identification under the screen using Qualcomm ultrasound will be disclosed.

Qualcomm did not specifically determine the smartphone model equipped with this sensor. However, it has been rumored in the industry that Qualcomm's ultrasonic sensor has decided to be applied to two models of Samsung Galaxy S10.

Qualcomm is introducing an off-screen fingerprint identification sensor using ultrasound

It is said that Qualcomm's ultrasonic sensor, that is, the off-screen fingerprint identification technology applied to S10, has the characteristics of high permeability.

Alex katouzian, senior vice president and general manager of the mobile business unit of Qualcomm, said in an interview with reporters on December 5 that "Sony's sensor is very small and can be easily penetrated through all display layers in the terminal. If it is configured at any position, it can successfully identify fingerprints." he stressed that "even if the fingers are stained with soil, dust, water, etc., there are no obstacles in identifying fingerprints."

Ultrasonic waves have the property of penetrating and passing through substances. This is why ultrasound can be used to examine the fetus in the abdomen. Qualcomm's ultrasonic sensors also take advantage of this feature. The sensor is configured on the back of the display screen. Although the screen can only be seen from the outside, the ultrasonic wave can reach the fingerprint through the display screen. While touching the fingerprint, the changing ultrasonic value can be measured, and the fingerprint shape can be distinguished by algorithm.

Qualcomm's ultrasonic sensor has very high transmission intensity. Because not only the screen, but also the foreign matter stuck to the hand can be identified by fingerprint. At present, the capacitive fingerprint identification sensor, which is most widely used in smart phones, can not work normally when the finger is stained with sweat or water, and the off screen fingerprint identification can not be carried out.

However, the commonly known ultrasonic sensor can only operate on the flexible OLED display. The chief vice president of Qualcomm said that "LCD cannot be used" and said that "because the proportion of flexible OLED screens on smartphones is expanding, the ultrasonic sensor market will expand."

Gaotong said that the ultrasonic fingerprint identification sensor will be applied to mobile phones in the first half of next year. Samsung Galaxy S10 will be launched in the first half of next year.
