Description

A kind of flexible LED display screen

Technical field

The utility model relates to LED display, relates in particular to a kind of flexible LED display screen.

Background technology

At present; Known LED display structure all is body structure basically; Led display unit plate with the polylith hard is fixed on the casing exactly, forms single LED and shows module, during use these modules is spliced and combined into a LED display; Connect power supply and control system, play various literal and video image.The following characteristics of such LED display: 1. the least unit of forming LED display--LED shows that module all is a rigidity, can not flexural deformations, so general LED display also is a rigidity, and cannot flexural deformation, manufacture very difficulty of different in nature LED display; 2. volume weight is bigger, is difficult to whole Transporting, needs the LED display partition packing that will debug in advance during installation; Be transported to the working-yard, again the LED unit that separates shown that module re-assemblies debugging well, can come into operation; Use if flow; Need dismounting transportation repeatedly, this brings difficulty for the installation and the transportation of LED display, can consume great amount of manpower and material resources and financial resources.

Some flexible LED display screens are also arranged on the market at present, and a kind of structure is: single LED bulb is fixed on the cloth, with the back side of electric wire at cloth these LED is coupled together then, form a flexible LED display screen; A kind of in addition structure is that several LED lamps are welded on the rectangular circuit board; Again rectangular circuit board is packed into and form LED lamp bar in the shell; Then with these LED lamp strip units on cloth, LED lamp bar is coupled together with electric wire at the back side of cloth, form the flexible LED display screen; Also having a kind of structure is that the flexible PCB that has welded LED and electronic devices and components is installed in the soft rubber sleeve, forms the flexible LED lamp bar, the flexible LED lamp bar is arranged to be installed on the cloth cover then, forms a flexible LED display screen.

More than several kinds of structures following defective is arranged: 1. the connection electric wire at the screen body back side is many, breaks down easily, as long as wherein any wire loose contact; Will influence its use; In transportation and use, installing/dismounting repeatedly, the folding electric wire that all can cause damage poor reliability; 2. flexible LED lamp bar folding through repeatedly can cause flexible PCB internal copper thread breakage, and the components and parts loose contact needs often maintenance, and this also can influence the normal use of monoblock display screen; 3. in the above structure, LED bulb and flexible LED lamp bar are installed on the soft cloth cover, but the flexible nature of cloth is difficult to let monoblock flexible LED display screen keep a plane; And LED has directed luminous characteristics; The out-of-flatness meeting of screen body causes the LED light emission direction of diverse location different, widely different, and this species diversity can cause the brightness of monoblock LED display, color inconsistent; Image frame is inhomogeneous, the consequence of image quality; 4. outward appearance is plain.
