Apple Exploring New Display Technologies In Attempt To Raise Privacy On iOS Devices

Apple hit today U.S Patent and Trademark Office with another application patent with name of “Systems and Methods for Electronically Controlling the Viewing Angle of a Display”. The original inventor of this technology David Gere, describes the interesting privacy mode which activates the function that directs the light beams in different directions, preventing a person close to glance on the display and only allow those users to view the screen content who sits in front of it.

Patently Apple explains it more:

The new privacy option mode only allows those directly in front of the display to view its content. Anyone on the periphery would simply see a blank display. A number of professions may find this feature very appealing. The patent also vaguely points to this technology being used in association with a future pico-like projection system and/or 3D holographic display.

Well, after hearing about this technology you must be curious about it to know, How it works? So, 9to5mac has described it works a little more:

The trick for locking out peripheral viewing is a simple one, Apple argues. Picture elements comprising the display could be controlled by directing a light beam towards a liquid crystal material and steering it via microscopic mirror-like structures that apply a variable electrical control signal to the liquid crystal material.


So now what you think about this act by Apple, Is it useful for you?
