Revealed a patent recently reported that the company Apple is working to develop scanners for fingerprints placed under the screen iPhone phone, eliminating the need to use the “Home” button, and therefore the possibility that the screen occupies the entire front of the phone space, which speaks of rumors that the company will do with the next phone .

It describes the patent, which was not developed by Apple itself , but purchased as part of a deal to buy the screens , “Lux View” LuxVue company in 2014 , a system that uses “emitting diodes light” LEDs mounted below the screen are both exploring the finger site, scanning its surface to be able to read fingerprints.

Word in the patent published by the US Patent Office and Trademark Office on Tuesday: “When you put the finger on the lower transparent layer, the emitting diodes infrared and existing under the screen detects infrared light Almntba and reflected from the furrows of the surface of the finger.”

She said the patent: “Then go around the red light rays Almntba this to the output as a bitmap image processor where it is processed to determine the unique fingerprint pattern surfaces. And because the screen can feel the infrared light, they are able to carry out the process to determine the shape of the surface of the finger even when the screen emit almost no visible light. ”

The focus of the technology developed by the company to use LuxVue emitting diodes light placed under the screen to clone the ability to detect the presence of a finger or other interactive elements on a glass screen.

For comparison, the majority of mobile devices technology uses capacitive touch screen, which reveals the change in capacitance when smooth finger or other vectors of electricity screen elements. This technique is also used in many of fingerprint sensors and other devices, but maligned they do not work well in cold weather, or when covered finger glove, but if the surface of the carrier gloves.

It describes the patent granted to Apple ‘s use of a set of sensors based on emitting diodes to light under the screen to clone each of the function of the touch screen and traditional capacitive, and scanners fingerprints, along the lines of the main button on the iPhone phone that supports read fingerprints and known as the Touch ID.

It is noteworthy that Apple is not the only company working on new technologies that allow the transfer of the necessary elements for the operation of the smart phone to the bottom of the screen. It is these elements, ambient light sensors, which you adjust the screen brightness to suit the surrounding environment, as well as sensors that turn off the screen when you hold the phone to the ear, and the ear headphones, the front of the camera.

This is those components placed below the screen and one of the biggest obstacles standing in the way provide a phone with a screen occupies 100% of the front, where he still edges around the screen is necessary to cover the side of the phone and the upper and lower edges as well as space.
