Abstract
A method and system for enhanced viewing of a display device is disclosed in this application. In some implementations, a method and system for improving a perceived contrast of a screen of a display device is disclosed. Some implementations may also relate to a method and system for privately viewing content displayed on a screen.
Claims20
An eyewear device for improving a perceived contrast of a screen, the eyewear device comprising:
- at least one optical element configured to receive light emitted from a video screen, the at least one optical element comprising:
- a first passband configured to transmit a first transmitted range of wavelengths of light through the at least one optical element from the video screen, wherein the first passband is configured to block a plurality of visible wavelengths of light outside of the first transmitted range of wavelengths, the plurality of visible wavelengths comprises a first blocked range corresponding to shorter wavelengths than the first transmitted range and a second blocked range corresponding to longer wavelengths than the first transmitted range;
- a second passband corresponding to a second transmitted range of wavelengths of light, the second transmitted range corresponding to longer wavelengths than the second blocked range, the second passband being further configured to block light at a third blocked range of wavelengths of light, the third blocked range corresponding to longer wavelengths than the second transmitted range;
- a third passband corresponding to a third transmitted range of wavelengths of light, the third transmitted range corresponding to longer wavelengths than the third blocked range.

A method for improving a perceived contrast of a video screen, the method comprising:
- receiving a first signal from a transmitting device, the first signal corresponding to a first pattern of light emitted from the video screen;
- outputting a second signal from at least one circuit or processor in response to the receipt of the first signal;
- varying a transparency of at least one optical element in response to the second signal, the transparency being coordinated with the first pattern of light emitted from the video screen.
A system for privately viewing an image displayed on a video screen, the system comprising:
- at least one optical element, the at least one optical element of a display device being operable to vary in transparency;
- a receiver device being operable to receive a first signal from the display device;
- and
- at least one circuit operable to receive the first signal from the receiver device and transmit a second signal to control the transparency of the at least one optical element in response to the first signal, wherein a pattern of the variation in transparency of the at least one optical element corresponds to a pattern of transmission for a hidden image on the video screen.
