And LED luminescent layer 300 will not influence the flexible degree of each flexible circuit board 210, basement membrane 100 etc..
It should be noted that in general, homogenizing the light that film layer 400 is mainly issued to uniform LED luminescent layer 300.It can manage
After the light source that Xie Di, LED luminescent layer 300 issues injects the one end for homogenizing film layer 400, it may occur that refraction, reflection and scattering, finally
Become the secondary souce that area is bigger, the uniformity is more preferable and coloration is more stable, another end-fire of film layer 400 is finally homogenized from this
Out.
Further, a kind of specific embodiment as flexible LED display module provided by the utility model, in general,
Multiple 310 array arrangements of LED pixel unit on each flexible circuit board 210, in this way, can ensure that LED luminescent layer 300 issued
The uniformity of light source and have corresponding brightness.Certainly, in fact, can also there is other different arrangement forms as needed.
Further, a kind of specific embodiment as flexible LED display module provided by the utility model, each LED
Pixel unit 310 includes red-light LED light-emitting component 311, green LED element 312 and blue-ray LED light-emitting component 313, namely
It is to say, in order to which display effect is more preferable, three colors (red, green, blue (RGB)) LED luminescence component in trichromatism can form one
Pixel.Moreover, as shown in Figures 2 and 3, red-light LED light-emitting component 311, green LED element 312 and blue-ray LED
Light-emitting component 313 is arranged in " product " font.In this way, compared to the arrangement form that " one " word in Fig. 4 arranges, each LED pixel unit
310 brightness can be more uniform.Certainly, in practical applications, the structure that " one " word arranges shown in Fig. 4 can also be used.
Further, a kind of specific embodiment as flexible LED display module provided by the utility model, in this reality
It applies in example, the thickness range of flexible LED display module is 0.3mm~1.0mm.Certainly, indeed, it is possible in 1.0mm or so.Separately
Outside, the planar dimension of the flexible LED display module is not fixed, and can be determined according to actual needs.Specifically in the present embodiment, this is soft
Property LED display module with a thickness of 0.3mm, planar dimension is 200mm × 200mm.
Further, a kind of specific embodiment as flexible LED display module provided by the utility model, Duo Gerou
Property LED display module splicing together after planar dimension range be 5 × 2.8m~40 × 22.4m.Therefrom, it may be appreciated that ground, respectively
Flexible LED display module can mutually splice, and each flexible LED display module can be spliced into arbitrary dimension according to actual needs
Large screen, its usual spliced full-size is 40 × 22.4m.Specifically in the present embodiment, it can be spliced into large screen ruler
Very little is 31000mm × 20000mm.
The utility model also provides a kind of display screen 10, which includes above-mentioned flexible LED display module 20, and
Display screen 10 is spliced by multiple flexible LED display modules 20.It is to be appreciated that the planar dimension range of the display screen 10 is
5 × 2.8m~40 × 22.4m belong to large-sized flexible display screen.It should be noted that passing through each flexible LED display module
Assembling, mainly can be assembled into LED display flexible for the display screen 10.
It should be noted that as shown in figure 5, above-mentioned flexible LED display module 20 be equipped with connect with control system (not shown)
Connectivity port 21, in this way, each LED pixel list in LED luminescent layer 300 can be driven by control system after on-load voltage
Member 310 shines, and also processed picture signal can be conveyed to display screen 10 by route by control system, realizes and shines
Display etc..Obviously, which can be applied to the places such as cinema as display screen.It should be noted that specifically at this
In embodiment, as shown in fig. 6, offering multiple connecting holes 11 around display screen 10, passed through by line piece such as rope corresponding
The display screen 10 can be fixed on display/panel bracket by connecting hole 11.Certainly, in practical applications, others side also can be used
