Abstract

An adjustable LED display module is provided, including a plurality of light-emitting units, and at least a set of spacing adjusting mechanism. The spacing adjusting mechanism is of a retractable grid-like structure or a retractable mesh-structure. The plural light-emitting units are distributed on different locations of the components of the spacing adjusting mechanism. When the spacing adjusting mechanism operates to adjust the spacing, at least spacing between some neighboring light-emitting units will change so that the location after adjustment will vary. Hence, the display module will have different form factor and light dots arrangement to provide higher flexibility to fit various application environments and conditions as well as convenience for storage and transportation when contracted.

Claims

1. An adjustable light-emitting diode (LED) display module, comprising:

a plurality of light-emitting units; and

at least a set of spacing adjusting mechanism, said plural light-emitting units being distributed to different locations on components forming said spacing adjusting mechanism, when said spacing adjusting mechanism adjusting, at least spacing between some said light-emitting units being changed so that said LED display module having different length or width.

2. The adjustable LED display module as claimed in claim 1, wherein said spacing adjusting mechanism has a retractable grid-like structure.

3. The adjustable LED display module as claimed in claim 2, wherein said spacing adjusting mechanism comprises a plurality of light fixture racks and at least a set of linkage set, said linkage set forms a cross and are connected to the back of said light fixture racks so that said light fixture racks can expand and contract along a single direction in a retractable grid-like manner, and said plural light-emitting units are attached to the same side of said light fixture racks.

4. The adjustable LED display module as claimed in claim 3, wherein each said light fixture rack has a plurality of light-emitting units attached to surface of said light fixture rack and said light-emitting units have the same spacing.

5. The adjustable LED display module as claimed in claim 1, wherein said spacing adjusting mechanism has a retractable mesh-like structure.

6. The adjustable LED display module as claimed in claim 5, wherein said spacing adjusting mechanism comprises a plurality of X-shape coupling units coupling together, each said X-shape coupling unit comprises two linkage rods coupling at the middle point, and each said X-shape coupling unit has a plurality of light-emitting units attached.

7. The adjustable LED display module as claimed in claim 6, wherein said light-emitting units are located at the middle points between said coupling point of said linkage rods and four endpoints of said X-shape coupling unit.

8. The adjustable LED display module as claimed in claim 1, wherein said spacing adjusting mechanism has a retractable grid-like mechanism, comprising a plurality of light fixture racks and at least a set of retractable device, said retractable device is connected to back of said light fixture rack, and said light-emitting units are attached to the same side of said light fixture rack.

9. The adjustable LED display module as claimed in claim 1, wherein said light-emitting unit is an LED light source comprising red LED, green LED and blue LED.
