DETAILED DESCRIPTION OF THE INVENTION
Before the subject invention is further described, it is to be understood that the invention is not limited to the particular embodiments of the invention described below, as variations of the particular embodiments may be made and still fall within the scope of the appended claims. It is also to be understood that the terminology employed is for the purpose of describing particular embodiments, and is not intended to be limiting. Instead, the scope of the present invention will be established by the appended claims.
In this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs.
Turning now to the figures, FIG. 1 depicts a prior art flexible LED display panel 1. The panel 1 comprises a flexible fabric curtain 2 upon which are affixed numerous LED's 3 in a density of about 2500 pixels per square meter. Each side of the panel 1 includes a number of signal connectors 4, for a total of eight (8) connectors shown in FIG. 1. Data boxes 5 associated with various arrays of LED's 3 are shown arranged in a grid on the rear surface of the display panel 1. A receiving box 6 located among the data boxes 5 is used to route the many and various electrical connections required to operate the panel 1. The panel 1 receives AC power from an external source 7, typically 120V AC power, which is transformed to 5V DC power 8 that is connectable to one or more additional panels as needed. A data cable 9, such as Category 5 or 6 LAN cable, extends from the receiving box 6 having processing electronics for communication with a computer 10. For suspension of the flexible LED panel 1 from a structure, the panel 1 includes a number of straps 11 which terminate in a rigid bar 12 that can be secured by the supporting structure on site.
Thus, when the panel 1 is used in an assembly with other panels, a number of connections must be made. For example, the signal connectors 4 on each side must be connected to corresponding signal connectors on the adjacent panel. This process is quite time-consuming, and can lead to failure of the connectors with so many connections to be completed and disconnected on a repetitive basis. Given the urgency with which such panel assemblies need to be completed on a tight time frame, these inefficiencies can be expensive to all parties. Also, it is not possible to connect such panels vertically, because the strap 11 and bar 12 arrangement does not permit a flush mechanical connection that allows seamless positioning of LED pixels in the vertical direction.
In FIG. 2, it can be seen that all signal connections in the improved panel 20 have been consolidated into a single connector 14 having leads 14A, 14B for input and output, respectively, labeled as Ethercon In and Ethercon Out, which allows quick and easy connection between panels, rather than as many as eight connections. The connector 14 extends from a processor panel 15 having suitable processing electronics for control of the LED's 3, and the processor panel 15 is located on the rear of the panel 20 along with the data boxes 5 which are interconnected as shown in FIG. 2. Power 16 from an external source is provided at 120V AC to various distribution points 17 and transformed in 5V DC power for the data boxes 5 and the processor panel 15. Although the number of such power distribution points 17 may change to suit the particular design of the panel 20, twelve such power distribution points 17 are shown in a preferred configuration. As indicated in FIG. 2, the connector 14 is operatively in communication with a computer 10 which controls the LED display 3 via the processor panel 15. The computer 10 includes software programming that can be controlled by a user to direct the LED's to display any desired image. Importantly, when the connectors 14 of various panels are connected to one another using their respective leads 14A (input) and 14B (output), and a single connector lead 14A from one panel 20 is also connected to the computer 10, all of the connected panels 20 are thus controlled in unison, such that control data signals provided by the computer 10 result in a harmonized image across all panels 20 as if the multiple panels 20 were acting as a single display. While a wired connection is shown, it also possible to connect the input connector lead 14A to a wireless device (not shown), such that wireless communication of the control data from the computer 10 can also be achieved.
Likewise, the improved panel 20 includes an upper and lower rigging bar 21, 22. Each such rigging bar 21, 22 is located behind the LED array 3, and contain a number of holes with fastening hardware such that a rigid attachment to other vertically attached panels 20 is available either above or below the first panel 20. The rigging bars 21, 22 are mounted flush with the last upper and lower rows of LED pixels. When adjacent panels are connected in this fashion, the LED pixels between connected panels are essentially continuous, making for a more uniform and desirable image. Importantly, such panels 20 may be connected to one another both vertically and horizontally, allowing a large matrix of panels 20 to be assembled for virtually any size or shape to display the desired text or imagery as controlled by the computer 10.
FIGS. 3 and 4 depict the processor panel 15 box 25 and cover 26, respectively, for use with the improved LED display panel 20. The box 25 conveniently consolidates the connections which enter the processor panel 15, and from which the single Ethercon connector leads 14A, 14B extend before communication with either an adjacent panel and/or the computer 10.

The citation of any reference is for its disclosure prior to the filing date and should not be construed as an admission that the present invention is not entitled to antedate such reference by virtue of prior invention.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention set forth in the appended claims. The foregoing embodiments are presented by way of example only; the scope of the present invention is to be limited only by the following claims.
