Abstract

In a method for determining a position of at least one display screen within an array of coupled display screens an emitted signal from an adjacent display screen is detected. The detecting is performed by a sensor coupled with a side of a plurality of sides of a display screen. A positional code number is determined based on the detecting. The positional code number includes a bit number corresponding to a detection of the signal emitted from the adjacent display screen.

First claim

What we claim is:

1. A non-transitory computer-readable storage medium comprising instructions stored thereon which, when executed by a computer system, cause said computer system to perform a method for determining a position of at least one display screen within an array of coupled display screens, said method comprising:
detecting signals concurrently emitted from each adjacent side of an adjacent display screen, said detecting concurrently performed by sensors adjacent said each adjacent side of said adjacent display screen; and
determining a positional code number based on said detecting, said positional code number comprising a bit number corresponding to a detection of said signal emitted from said adjacent display screen.

2. The non-transitory computer-readable storage medium of claim 1 , wherein said method further comprises instructions for:
sending said positional code number to a receiver of positional codes.

3. The non-transitory computer-readable storage medium of claim 1 , wherein said method further comprises instructions for:
performing said detecting and said determining after signals at corner display screens of said array of coupled display screens are turned on.

4. The non-transitory computer-readable storage medium of claim 1 , wherein said method further comprises instructions for:
repeating said detecting and said determining after signals at corner display screens of said array of coupled display screens are turned off.

5. The non-transitory computer-readable storage medium of claim 1 , wherein said determining a positional code based on said detecting, said positional code comprising a bit number corresponding to a detection of said signals concurrently emitted from each adjacent side of an adjacent display screen comprises instructions for:
if a signal is detected at said side of said display screen, wherein said signal is emitted from said adjacent display screen, then determining a positional code of a bit number 1; and
if a signal is not detected at said side of said display screen, then determining a positional code of a bit number 0.

6. The non-transitory computer-readable storage medium of claim 1 , wherein said detecting signals concurrently emitted from each adjacent side of an adjacent display screen, further comprises instructions for:
detecting a signal emitted from a signal output of an adjacent display screen, wherein said detecting is performed by a signal detector coupled with a side of a display screen, wherein said signal detector communicates through a single cable coupled with said array of coupled display screens.

7. The non-transitory computer-readable storage medium of claim 1 , wherein said detecting signals concurrently emitted from each adjacent side of an adjacent display screen, further comprises instructions for:
detecting a signal emitted from a signal output of an adjacent display screen, wherein said detecting is performed by a signal detector coupled with a side of a display screen, wherein said signal detector communicates wirelessly with other signal detectors coupled with said array of coupled display screens.
