Screen fingerprints to unlock is the best fingerprint unlock solution for full display
Qualcomm under the fingerprint technology is expected next year mass production OLED screen into commercial difficulties. Raj Talluri, senior vice president of Internet connectivity at QUALCOMM, said Qualcomm's fingerprint recognition technology will be available next year and most of its flagship phones will use the technology.
Talluri said that the current screen fingerprint recognition technology is still in the stage from the concept of production, they found that the fingerprint sensor needs to penetrate the different materials, the parameters will be different, Qualcomm's goal is to make the technology can be applied to all materials.
With the smartphone into the era of full screen, mobile phone screen front of the fingerprint unlock space by squeezing, fingerprint lock placement program appeared in different programs and routes. Not long ago released Samsung Note 8 will be placed on the fuselage on the back of the fuselage. It is reported that the upcoming debut of the Huawei Mate 10 also uses a back fingerprint to unlock the program.
In fact, under the screen to unlock the fingerprint is a comprehensive screen background, the best fingerprint unlock program, but there are still many technical difficulties. At the World Mobile Conference held in Shanghai in June this year, VIVO exhibited the prototype mobile phone using the high-pass ultrasonic fingerprinting technology, but the phone is still in the testing phase and cannot be mass-produced.
Talluri that high-pass screen fingerprint recognition technology can be applied next year, which also means that next year released several flagship mobile phone millet 7, Samsung Galaxy S9, LG G7, HTC U12 and so may have to use the screen fingerprint recognition technology, This is the development of smartphone fingerprint recognition technology, is also a huge breakthrough.
It is understood that Qualcomm's new generation of fingerprint solutions can penetrate all screens except TFT, you can also penetrate the back shell metal cover, you can unlock in the water and so on. This means that the user is wet in the hand of the state, can still achieve accurate fingerprints to unlock.
Compared with the capacitance and optical fingerprint recognition, the advantages of ultrasonic fingerprint recognition is that it does not need to open the hole, for the full screen completely let way, improve the phone's waterproof and dustproof. The wet and dry requirements of the fingers to reduce the wet hands can unlock the phone.
But there are industry insiders pointed out that the current ultrasonic fingerprints can only penetrate the OLED screen. However, OLED panel two manufacturers, LG production capacity, Samsung's production capacity is almost Apple monopoly. Other manufacturers want to achieve under the screen fingerprint production, in the supply chain is still facing the test.
