Apple presented in 2013 an innovation that little by little has been gradually reaching almost any mobile device worth its salt. We are talking about fingerprint sensors, those security tools that have changed not only the way we interact with mobile phones, but have even reached the way we pay in regular stores.
Since then, the fingerprint sensor has become more and more common, but the need to occupy a place in the front has become a stumbling block in an age where the front bezel tends to be minimized. Qualcomm has presented its fingerprint sensor, the same one that uses the latest model from the Chinese firm Vivo.
This integrated fingerprint sensor from Qualcomm is capable of being embedded in an aluminum panel and even under the glass of an OLED screen. This undoubtedly represents a very important advance, since we can include the fingerprint reader directly below the screen. This Qualcomm sensor could radically change this technology as we know it so far, which is why they have rushed to present it in the latest model of the Chinese brand Vivo.
This greatly complicates a technology that Apple intended to include in the iPhone 8, since Qualcomm sensor will have the consequent royalties for use, and as we well know, Apple is currently immersed in legal proceedings against Qualcomm precisely for the supposedly excessive payment of this type of rights for technological patents.
Returning to the issue at hand, the sensor will work on OLED displays up to 1,2 millimeters, as well as any glass cover up to 0,8 millimeters. In the same way, will work on aluminum panels with a thickness of 0,65 millimeters, Although this last detail seems less complicated, since it would end up placing the sensor at the rear, precisely what is intended to be avoided.
