Device with flexible led display module and method using same

Abstract

A light emitting diode (LED) device has one or more LED display modules. At least one of the one or more LED display modules has a plurality of LED display sub-modules. A plurality of LED display sub-modules are flexibly connected to each other to form a flexible display surface.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 475,055, filed March 22, 2017, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to light emitting diode (LED) devices and systems, and more particularly, to devices and systems having flexible LED display modules and methods of employing the same. Background technique [0004] Light emitting diodes (LEDs) are known and have been widely used in industry, primarily as low power light indicators. In recent years, LEDs with greater power output or greater luminous intensity have been developed for lighting. LEDs and the like provide better energy efficiency, safety, and reliability, and replace other types of lamps on the market (eg, incandescent lamps, compact fluorescent lamps (CFLs), etc.). Since daily lighting constitutes a significant portion of the grid load and s...

Problems solved by technology

Excessive heat generation is also a threat to the safe and reliable operation of digital LED sign displays

[0016] Additionally, the use of fans or rotating parts for digital LED signage displays significantly reduces their reliability as rotating parts are often the point of failure in these products

[0017] Since each LED driver 22 is connected to the central controller 20 via a cable 16B (e.g., a ribbon cable), large digital LED sign displays 10 typically require one or more ribbon cables 16B with a large number of wires to make the digital LED sign display 10 Expensive and unreliable due to the high risk that the wires in the ribbon cable may become disconnected and / or damaged over time, especially in outdoor applications

Additionally, these ribbon cables are often a point of failure for digital LED signage displays

[0018] Because all of the above components are received in the cabinet 14, prior art LED signage displays are often bulky and thus difficult to install and handle
