The rapid diffusion of the first fingerprint sensors under the displays has allowed this technology to evolve in a short time; however, while we find ourselves dealing with LCD panels not yet supported – albeit for a short time – and sensors that cover only small portions of the screen, a further evolutionary step could come from Huawei.
The Shenzhen giant would have patented a new sensor capable of covering the entire area of the screen, without any kind of discontinuity. The patent is still pending approval, but has already been filed in six markets, including China, Europe, the United States, Japan, Korea and India.
As reported by the editorial staff of AndroidAuthority, this technology would not be limited only to extending the area to the entire display, but would also allow to customize the unlocking of each individual application, carrying out the verification directly when it is opened. As if that were not enough, the patent would also illustrate another interesting possibility, that is to activate the sensors only in a selected area of the screen. In this case, the sensor would consume much less energy, and would allow the user to choose the activation area most suited to him.
In short, if it is true that it is an interesting technology capable of representing a natural evolution of the current sensors under the display, history teaches us that the road between a patent and the real implementation is often long and convoluted – and often not. you don't even reach your destination. However, considering the direction the market is taking and the investments that are being made to bring this technology to LCD panels, Huawei's solution could find positive implications in a short time, and also be pursued by the competition.
