Video display and method providing vision correction for multiple viewers

1. A multi-view display screen system comprising:

a TV display device for providing vision correction for multiple users without use of eyeglasses and for measuring room lighting where the users are located, the display device comprising

a vision correction layer, and

a holographic layer overlaid on said vision correction layer and in closer proximity to viewers of the display device than the vision correction layer;

a camera aimed at viewers of said display device and coupled to a processor for conducting facial recognition of and detecting the identity of a first user and a second user, determining a first distance between said first identified user and the display device and a second distance between said second identified user and the display device, and

determining a first angle of view for the first identified user and a second angle of view for the second identified user,

wherein said processor associates the first identified user with a first preloaded eye prescription and said first distance and associates the second identified user with a second preloaded eye prescription and said second distance;

a vision correction module for receiving a source video signal, replicating the source video signal into two or more source video signals, processing a first replicated source video signal and a second replicated source video signal in parallel,

wherein said first replicated source video signal is processed through multiple iterations to generate a first corrected video signal based on said first distance, additional data corresponding to vision preferences of said first identified user, first preloaded eye prescription, and said measured lighting,

wherein said second replicated source video signal is processed through multiple iterations to generate a second corrected video signal based on said second distance, additional data corresponding to vision preferences of said second identified user, second preloaded eye prescription, and said measured lighting,

wherein said vision correction module outputs the first corrected video signal to the vision correction layer which generates a first corrected video at a time t 1 , and outputs the second corrected video signal to the vision correction layer which generates a second corrected video at a time t 2 ; and

a holographic module synchronized with the vision correction module and configured to

modulate the holographic layer at said time t 1 based on said first angle and said first user identity to allow the first user to view the first corrected video while at the same time generating an adjustable desired level of interference effect to be displayed at said second angle corresponding to the second user to block in an adjustable manner and to at least partially block the first corrected video from view by the second user, and

modulate the holographic layer at said time t 2 based on said second angle and said second user identity to allow the second user to view the second corrected video while at the same time generating an adjustable desired level of interference effect to be displayed at said first angle corresponding to the first user to block in an adjustable manner and to at least partially block the second corrected video from view by the first user.

2. The multi-view display screen system of claim 1 , wherein the first prescription and second prescription correspond to different eye deficiencies.

3. The multi-view display screen system of claim 1 , wherein the TV display device comprises a plurality of liquid crystal displays.
