Device and method for arranging a display

1 . A projection display device alignment system, comprising:

a viewing screen;

a projection display device displaying video on the viewing screen; and

an emitter emitting a medium,

wherein an indicator indicates that the projection display device is aligned with the viewing screen in response to the medium from the emitter.

2 . The system of claim 1 , wherein the emitter is a laser.

3 . The system of claim 1 , wherein the medium is a radio signal.

4 . The system of claim 1 , further comprising:

a receptor receiving the medium from the emitter,

wherein the indicator is coupled to the receptor.

5 . The system of claim 4 , wherein the indicator provides an audio or a visual indication that the projection display device is aligned with the viewing screen.

6 . The system of claim 4 , wherein:

the emitter is located at the screen; and

the receptor is located at the projection display device.

7 . The system of claim 6 , wherein the indicator displays on the viewing screen from the projection display device.

8 . The system of claim 7 , wherein the indicator indicates that the projection display device is aligned with the viewing screen when the projection display device is substantially centered with respect to a horizontal axis and/or a vertical axis of the viewing screen.

9 . A method for aligning a viewing screen with a projection display device, comprising:

emitting a medium;

determining the position of the viewing screen with respect to the projection display device; and

adjusting the projection display device or the viewing screen to be aligned with each other.

10 . The method of claim 9 , further comprising:

receiving the medium.

11 . The method of claim 10 , further comprising:

indicating that the projection display device is aligned with the viewing screen,

wherein indicating that the projection display device is aligned with the viewing screen comprises an audio or a visual indication.

12 . The method of claim 11 , indicating that the projection display device is aligned with the viewing screen device occurs when the indicating that the projection display device is substantially centered on a horizontal axis and/or a vertical axis of the viewing screen.

13 . A self-leveling viewing screen, comprising:

a viewing screen; and

a level device disposed on the viewing screen,

wherein the level device indicates that an edge of the viewing screen is substantially level.

14 . The screen of claim 13 , wherein the level device indicates that the top edge of the viewing screen is substantially level.

15 . The screen of claim 14 , wherein the screen comprises a housing and the level device is disposed in the housing.

16 . The screen of claim 15 , wherein a motor is disposed within the housing and the motor raises and lowers the viewing screen.

17 . The system of claim 1 , further comprising:

an image capture device capturing an image of the viewing screen; and

an adjuster that adjusts a position of video displayed on the viewing screen along a horizontal axis and a vertical axis.

18 . The system of claim 17 , wherein:

the adjuster comprises a lens shifter disposed within the projection display device, and

the lens shifter adjusts the position of video displayed on the viewing screen along the horizontal axis.

19 . The system of claim 18 , wherein:

the adjuster further comprises a telescoping post, and

the telescoping post adjusts the position of video displayed on the viewing screen along the vertical axis.

20 . The system of claim 18 , wherein the lens shifter adjusts the position of video displayed on the viewing screen along the vertical axis.

21 . The system of claim 17 , further comprising:

a control device coupled to the adjuster,

wherein a position of video displayed on the viewing screen is manually adjusted in response to a user input from the control device.

22 . The method of claim 9 , further comprising:

capturing an image of the viewing screen;

determining a position of projected video with respect to the video screen;

generating an adjustment signal based on the position of projected video with respect to the video screen; and

adjusting the position of projected video with respect to the viewing screen along a horizontal axis and a vertical axis.

23 . The method of claim 22 , wherein adjusting the position of projected video comprises adjusting the optics of a projection display device to adjust the position of projected video along the horizontal axis and/or vertical axis.
