A month after the launch of the iPhone 8 - although now it is speculated on with another unexpected new name -, the iPhone 7s and the iPhone 7s Plus, the creative machinery of Cupertino never sleeps. It is known that it is working on the iPhone 9 but the patents do not stop.
The last one that we have known simply has enchanted us, because it will allow us to control the angle of vision. So that we understand, that nobody will be able to look back over your shoulder to read what you do on your iPhone, iPad or Mac.
This patent has an entry date of June 30 of last year, but has been made public this Thursday under the name "screens with adjustable viewing angles" and uses a controllable electronic filter that we can adjust to polarize the screen. In this way, the user will choose it.
Lady, gossiping on public transport is over
The current LED screens have viewing angles as wide as possible, achieving even reaching 178 - half circumference -. Interestingly, the older LEDs had much lower viewing angles of up to 45 degrees. But now, you can modify it yourself.
The first implementation seems to be constituted by a liquid crystal screen that forms a kind of sandwich with the polarizable and colored layers. So apart from controlling the angle of view, we can also modify the brightness and intensity of colors and even omit or include images on the screen. Other possibilities of this technology include a backlight that is applied selectively to certain areas of the screen, so that we can illuminate or darken some sections.
But as we say, in addition to being integrated into the iPhone, it will not be limited to iOS devices. Most likely we will see it in the Apple Watch, the Mac and any other gadget that includes a screen.
