Panel display of multiple display units for multiple signal sources
First Claim
1. A panel display comprising a plurality of display units that form a display area, each said display unit having video random access memory (VRAM) for storing image data, a controller for processing broadcast data signals to provide said image data to said VRAM, and an image display panel for displaying said image data, wherein said controller for each said display unit is operable to accept concurrent broadcast data signals from multiple sources intended for said plurality of display units that form said display area, each said display unit being operable to process image information with respect to said display area independently from said multiple sources, calculate a relative location for each said display unit relative to other display units within said plurality of display units that form said display area, and extract an applicable portion of said image data from said broadcast data signals based upon said relative location.

Abstract
A panel display system having at least one source device coupled to a plurality of display units interconnected to form a larger display having any desired size and shape. Each display unit is a self-contained panel display having a video random access memory (VRAM) for storing image data, a controller for processing data signals to provide the image data to the VRAM, and an image display panel for displaying the image data. The self-contained panel displays substantially reduce the need for a separate driver card for each panel display, and substantially reduce the communications bandwidth between the source devices and the panel displays of the system. Means for interconnecting the display units include the use of data/control bus connectors and power line connectors, cables, network devices, local area networks, and/or wide area networks.

36. A panel display system comprising:
-
a plurality of display units arranged to form an image display area having a predetermined formation; at multiple sources coupled to said display area, wherein each said source broadcast control and data signals to said display unit of said display area, each said display unit being operable to process image information with respect to said image display area independently from said multiple sources, each display unit having a video random access memory (VRAM) for storing image data, a controller for processing said data signals to provide said image data to said VRAM, and an image display panel for displaying said image data; and means for interconnecting said plurality of display units, wherein said controller for each said display unit is operable to accept concurrent broadcast data signals intended for said plurality of display units that form said display area, calculate a relative location for each said display unit relative to other display units within said plurality of display units that form said display area, and extract an applicable portion of said image data from said broadcast data signals based upon said relative location. - View Dependent Claims (37, 38, 39, 40, 41, 42)
