Video display and method providing vision correction for multiple viewers

A video display system for multiple users in an environment, the system comprising:

• a display device having a holographic layer, the display device measuring lighting in the environment;
• a processor coupled to the display device, the processor configured to
• modulate the display device so that a first user at a positioned at a first angle to the display device and a second user positioned at a second angle with respect to the display device can view a non-distorted image from the display device;
• and
• a holographic module operated by the processor, the holographic module configured to
• adjustably modulate the holographic layer to at least partially block the non-distorted image to the first user by generating an adjustable level of interference effect displayed in the direction of the first user while, at the same time, allowing a second user to view the non-distorted image, and
• adjustably modulate the holographic layer to at least partially block the non-distorted image to the second user by generating an adjustable level of interference effect displayed in the direction of the second user while, at the same time, allowing the first user to view the non-distorted image;
• wherein the processor is configured to adjustably modulate the holographic layer or a vision correction layer to adjust for the measured lighting in the environment.

A multi-view display screen 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 the multiple users of the display device than the vision correction layer;
• a processor coupled to the TV display device;
• and
• a camera coupled to the processor and aimed at the multiple users of the display device,
• wherein the processor is configured to
• conduct facial recognition of each of the multiple users and identify a first user and a second user of the multiple users,
• associate a first prescription as corresponding to the first user and a second prescription as corresponding to the second user,
• via a vision correction module, receive a source video signal, process a first corrected video signal adjusting for the first prescription and a second corrected video signal adjusting for the second prescription, and output the first corrected video signal at a first time and the second corrected video signal at a second time, and
• via a holographic module synchronized with the vision correction module, adjustably modulating the holographic layer at the first time and adjustably modulating the holographic layer at the second time, wherein the processor is further configured to adjust the holographic layer or a vision correction layer based on lighting in the environment.
