Claims46
A system for providing a three dimensional video image to a user of 3D glasses, the system comprising:
- a power supply,
- first and a second liquid crystal shutters operably coupled to the power supply, and
- a control circuit operably coupled to the power supply and the liquid crystal shutters adapted to
- open the first liquid crystal shutter for a first period of time,
- close the first liquid crystal shutter for a second period of time,
- open the second liquid crystal shutter for the second period of time,
- close the second liquid crystal shutter for the first period of time, and
- transfer charge between the first and second liquid crystal shutters during portions of at least one of the first and second periods of time,
- wherein the first period of time corresponds to the presentation of an image for a first eye of the user and the second period of time corresponds to the presentation of an image for a second eye of the user.
A system for providing three dimensional video images, comprising:
- a pair of glasses comprising a first lens having a first liquid crystal shutter and a second lens having a second liquid crystal shutter, the liquid crystal shutters each having a liquid crystal, and
- a control circuit that alternately opens the first and second liquid crystal shutters and transfers charge between the liquid crystal shutters.
The system of claim 290, wherein the encrypted signal will only operate a pair of liquid crystal glasses having a control circuit adapted to receive the encrypted signal.
A method for providing a three dimensional video image using first and second liquid crystal shutters, the method comprising:
- closing the first liquid crystal shutter and opening the second liquid crystal shutter,
- then closing the second liquid crystal shutter and opening the first liquid crystal shutter, and
- transferring charge between the first and second liquid crystal shutters.
A computer program installed on a machine readable medium in a housing for 3D glasses having first and second liquid crystal shutters for providing a three dimensional video image to a user of the 3D glasses, the computer program comprising:
- closing the first liquid crystal shutter and opening the second liquid crystal shutter,
- then closing the second liquid crystal shutter and opening the first liquid crystal shutter, and
- transferring charge between the first and second liquid crystal shutters.
A system for providing a three dimensional video image using first and second liquid crystal shutters, the method comprising:
- means for closing the first liquid crystal shutter and opening the second liquid crystal shutter,
- means for then closing the second liquid crystal shutter and opening the first liquid crystal shutter, and
- means for transferring charge between the first and second liquid crystal shutters.
The system of claim. 33, wherein the synchronization signal comprises a synchronous serial data signal.
A system for providing electrical power to 3D glasses including left and right liquid crystal shutters, comprising:
- a controller operably coupled to the left and right liquid crystal shutters;
- a battery operably coupled to the controller;
- and
- a charge pump operably coupled to the controller;
- wherein the controller is adapted to transfer electrical charge between the left and right liquid crystal shutters when changing the operational state of either of the left or right liquid crystal shutter;
- and
- wherein the charge pump is adapted to accumulate electrical potential when the controller changes the operational state of either the left or right liquid crystal shutter.
A method of providing electrical power to 3D glasses including left and right liquid crystal shutters, comprising:
- transferring electrical charge between the left and right liquid crystal shutters when changing the operational state of either of the left or right liquid crystal shutters;
- and
- accumulating electrical potential when changing the operational state of either the left or right liquid crystal shutters.
A computer program stored in a machine readable medium for providing electrical power to 3D glasses including left and right liquid crystal shutters, comprising:
- transferring electrical charge between the left and right liquid crystal shutters when changing the operational state of either of the left or right liquid crystal shutters;
- and
- accumulating electrical potential when changing the operational state of either the left or right liquid crystal shutters.
A system for providing electrical power to 3D glasses including left and right liquid crystal shutters, comprising:
- means for transferring electrical charge between the left and right liquid crystal shutters when changing the operational state of either of the left or right liquid crystal shutters;
- and
- means for accumulating electrical potential when changing the operational state of either the left or right liquid crystal shutters.
