Patent ID: 8724026

Claim:
A method of displaying dual programs on a same display, the method comprising: displaying on the display during a first time interval, a frame of a first program using light polarized in a first polarization direction; displaying on the display during a second time interval, a frame of a second program, different from the first program, using light polarized in a second polarization direction, such that the displaying the frame of the first program and the displaying the frame of the second program appears to an unaided human eye to occur simultaneously and independently on the same display; continuing to display successive frames of the first and second programs in a time-alternating manner on the same display, such that the first program is enabled to be viewed by a first user, without the first user seeing the second program, through a first pair of polarized glasses, while the second program is enable to be simultaneously viewed by a second user from the same display, without the second viewer seeing the first program, through a second pair of polarized glasses that are polarized differently than the first pair of polarized glasses; transmitting a first electrical signal representing audio associated with the first program; and transmitting a second electrical signal representing audio associated with the second program.
