Abstract
A video display system for providing vision correction for multiple users may include a display device having a holographic layer and a vision correction layer. The system may also include a processor coupled to the display device to receive a first prescription corresponding to a first user and a second prescription corresponding to a second user, and to modulate the display device so that the first user at a first angle and the second user at a second angle can view a non-distorted image from the display device.
Claims17
A video display system for providing vision correction for multiple users comprising:
- a display device having a holographic layer and a vision correction layer;
- a processor coupled to the display device, the processor configured to
- receive a first prescription corresponding to a first user and a second prescription corresponding to a second user,
- modulate the display device so that the first user at a first angle and the second user at a second angle can view a non-distorted image from the display device.
A method of displaying vision corrected video for multiple users comprising:
- receiving, via a processor, a first prescription corresponding to a first user and a second prescription corresponding to a second user;
- modulating a display device having a vision correction layer and a holographic layer, through use of the processor, so that the first user at a first angle and the second user at a second angle can view a non-distorted image from the display device.
