Modular and Configurable Display Device
A modular display device includes a housing module having a plurality of open face compartments and a back wall having access openings therein registering with each of the open face compartments. A circuit board is mounted on the back wall of the housing module and carries a plurality of light-emitting diodes mounted thereon and being energizable by the circuit board to shine through the access openings and light up the compartment. A lens is provided for each of the compartments and attached to the housing module to close the open face compartment. Each lens has an alphanumeric or other message thereon which will be backlit by the light-emitting diodes so that information is displayed. A plurality of these housing modules are mounted together side by side in order to form a display board of scalable and customizable size depending upon the number of information messages to be displayed and signaled.
1 . A modular display device comprising:
a housing module having a plurality of open face compartments, said housing module including a back wall having an access opening therein registering with each of the open face compartments,
a circuit board mounted on the back wall of the housing module and having a plurality of light-emitting diodes mounted thereon, said light-emitting diodes being energizable by the circuit board to shine through the access openings in the back wall,
and a lens attached to the housing module to close at least one of the open face compartments, and the lens having an alphanumeric or other message thereon to be backlit by the light-emitting diodes upon selective energization of the light-emitting diodes so that information is displayed.
2 . The modular display device of claim 1 in which a plurality of such housings modules are mounted together side by side in order to form a display board of scalable and customizable size depending upon the number of information messages that are desired.
3 . The modular display device of claim 1 further comprising the housing module having a back cover that is attached to the back wall of the housing module to cover and protect the circuit board.
4 . The modular display device of claim 3 further comprising said back cover having vent openings therein to vent away heat from the circuit board.
5 . The modular display device of claim 1 further comprising at least two light-emitting diodes located in each access opening and having contrasting colors so the message includes both the alphanumeric message content and also a choice of color.
6 . The modular display device of claim 1 further comprising mounting brackets mounted on at least one side of each of the module boxes to enable the attachment together of a plurality of module boxes to form a large scale display device of desired size.
7 . The modular display device of claim 1 further comprising each lens being a transparent or translucent plastic with an alphanumeric message thereon.
8 . The modular display of claim 1 further comprising said lens being a seven segment light-emitting diode counter or alphanumeric light-emitting diode display.
9 . The modular display of claim 2 in which the housing modules are connected by an Ethernet connection employing the RS-485 communication standard.
10 . A modular display device comprising:
a housing module having a plurality of open face compartments, said housing module including a back wall having access openings therein registering with each of the open face compartments,
a single circuit board mounted on the back wall of the housing module and having a plurality of light-emitting diodes mounted thereon and registering with the access openings so that upon energization a light-emitting diode the resultant illumination will illuminate the open face compartment,
and a plurality of lenses bearing an alphanumeric message and being mounted on the housing module to close the open face compartment and be back lit by the illumination within the open face compartment.
11 . The modular display device of claim 10 further comprising a plurality of light-emitting diodes registering with each access opening and having contrasting colors so the message includes both the alphanumeric message content and also a choice of color.
12 . The modular display device of claim 10 further comprising the display device having a back cover that is attached to the back wall of the housing module to cover and protect the circuit board, said back cover having vent openings therein to vent away heat from the circuit board.
13 . The modular display device of claim 10 further comprising mounting brackets mounted on at least one side of each of the housing modules to enable the attachment together of a plurality of housing modules to form a large scale display device of desired size.
14 . The modular display device of claim 10 comprising a plurality of said housing modules joined together side-by-side to make a large scale display board of desired size.
15 . The modular display device of claim 14 further comprising mounting brackets provided on at least one side of each of the housing modules to enable the side-by-side joining together of the housing modules.
16 . The modular display device of claim 10 in which the circuit board carries at least one dip switch and at least one electrical connector, and the back cover has at least one access slot through which the dip switch and the electrical connector can be accessed by a technician.
17 . The modular display device of claim 10 further comprising said module housing having four open face compartments.
18 . The modular display device of claim 17 further comprising said housing module being of molded plastic construction with an interior dividing vertical wall and an interior dividing horizontal wall so that two upper open face compartment are arranged above two lower open face compartments.
