Apple's new patent: users can see the iPhone screen clearly when they wear sunglasses.

CTOnews.com, March 22 (Xinhua)-- according to a list published by the U.S. Trademark and Patent Office (USPTO), Apple has obtained a patent entitled US 11611058 B2, entitled "Devices and Systems using off-screen Image sensors." The most noteworthy aspect of the patent is that it allows users to clearly see what is displayed on the iPhone screen while wearing sunglasses.

Although current users can optimize by polarizing film, polarizer, polarizing layer or polarizing film on glass, the visual angle range is very narrow.

In its patent, Apple outlines an optical system that can be embedded at the bottom of the phone screen. Some of the patents for CTOnews.com translation are as follows:

The optical system can use the same light source to image the display and provide light to the sensor or sensor device.

The optical system can be adjusted with polarized light to dynamically and clearly display the screen content according to the user's visual angle. The optical system can also be configured to reduce the reflection of ambient light in the mobile device and to reduce the cross pollution of reflected and backscattered light to the imaging light of the display.
