In addition, a conventional screw fixing manner is not needed, a magnet is used for absorbing the main bodies, and the flexible LED display module is simple in structure and convenient to install.

Description

Flexible LED display module

Technical field

The utility model relates to a kind of LED display module, is specifically related to a kind of LED display module of flexibility.

Background technology

Because LED has that brightness is high, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and steady performance, and extensively be applied to various fields, and the LED display module is no exception, it relies on above-mentioned various advantages and is widely used in various places, does the main tool that mass information is propagated.Simultaneously the LED luminotron is day by day microminiaturized, and the resolution of LED display module is improved rapidly, in conjunction with the trend of HD video now, makes its application more and more wider.

On market, existing LED display module is all flat, general all forms a plane, the stent support of a customization of dependence by the rigid matrix of polylith.Display plane is stiff, many times is difficult to well incorporate surrounding enviroment, particularly in special-shaped environment, such as stage, passage, curved-surface building body of wall etc., display module is not collapsible, can't the nature be attached on main body, for example can not scrabble up cylinder or corrugated LED display.

In addition, existing rigid matrix brings also has integrity problem.Heavy module but has fragile panel, and in transportation, installation and maintenance process, slight collision, friction all might damage circuit or device, bring a lot of puzzlements to the user.

The utility model content

Technical problem to be solved in the utility model is, a kind of LED display module of flexibility is provided, and can make its torsional deformation, in order to be attached on the main body of various abnormity, and it is simple in structure, easy for installation, to solve the deficiency of prior art.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is that a kind of flexible LED display module comprises flexible PCB, protecting mask, paster LED chip and rubber layer; Described protecting mask is located at the front (being provided with the one side of paster LED chip) of flexible PCB; Described paster LED chip is embedded in protecting mask, and is electrically connected on flexible PCB; Described rubber layer is located at the reverse side of flexible PCB.

In order flexible LED display module to be adsorbed on various main bodys, be evenly distributed with several magnet in described rubber layer, by this rubber layer with magnet, can will flexible LED display module should be adsorbed on various main bodys with adsorbable magnet (for example irony main body).Further, in order to have concurrently attractive in appearance and to ensure absorption property, described magnet is the magnet of column type or the magnet of cubic type, preferably use diameter or length or widely be 5-9mm, and be highly 2-5mm.

For can easily be with the flexible LED display module torsional deformation, described rubber layer evenly has away from the one side of flexible PCB several rubber grains of distribution, this rubber grain can be column type, can be also cubic type, can be also other rule or irregular geometric configuratioies.

Further, described protecting mask is silica gel face shield or rubber face mask, can be also the face shield of other software materials, for example polypropylene material etc.

The utility model compared with prior art, has following advantage by said structure: 1. its flexible PCB that adopts, protecting mask and rubber layer are flexible, can make its any torsional deformation, in order to be attached on the main body of various abnormity; 2. do not need conventional screw fixation method, adsorb main body with magnet, it is simple in structure, easy for installation.Thereby solution of the present utility model existing rigid display module can not adaptive curved surface, and the problem of poor reliability.

Fig. 2 is vertical view of the present utility model.

Embodiment

Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.

As a specific embodiment, as depicted in figs. 1 and 2, a kind of flexible LED display module of the present utility model comprises flexible PCB 1, protecting mask 2, paster LED chip (not showing on figure) and rubber layer 4; Described protecting mask 2 is located at the front (being provided with the one side of paster LED chip) of flexible PCB 1; Described paster LED chip is embedded in protecting mask 2, and is electrically connected on flexible PCB 1; Described rubber layer 4 is located at the reverse side of flexible PCB 1.Wherein, flexible PCB 1 claims again " soft board ", is the P.e.c. made from flexible insulating substrate.Flexible circuit provides good electrical property, can satisfy design needs more small-sized and more high-density installation, also helps to reduce assembling procedure and strengthens reliability.Flexible PCB is the only solution that satisfies miniaturization of electronic products and movement requirement.Can free bend, coiling, folding, can bear the dynamic bendings of millions of times and not damage wire, can require to arrange arbitrarily according to space layout, and mobile and flexible arbitrarily at three dimensions, thereby reach integrated that the components and parts assembling is connected with wire; Flexible PCB can dwindle the volume and weight of electronic product greatly, and applicable electronic product is to the needs of high density, miniaturization, highly reliable future development.

Described protecting mask 2 is silica gel face shield or rubber face mask, can be also the face shield of other software materials, for example polypropylene material etc.The preferred silica gel face shield that uses both can play the dustproof and waterproof function, can also play good thermal conductivity.

In addition, described rubber layer 4 is located at the reverse side of flexible PCB 1, the components and parts 11(that is distributed with flexible PCB away from the one side of flexible PCB 1 is integrated chip for example), be evenly distributed with several rubber grains 41 between each components and parts 11, this rubber grain 41 can be column type, can be also cubic type, can be also other rule or irregular geometric configuratioies, is used for easily with the flexible LED display module torsional deformation.Be evenly distributed with several magnet 42 in described rubber layer 4, by this rubber layer 4 with magnet, can easily will flexible LED display module should be adsorbed on various main bodys with adsorbable magnet (for example irony main body).In order to have concurrently attractive in appearance and to ensure absorption property, described magnet 42 is the magnet of column type or the magnet of cubic type, preferably use diameter or length or widely be 5-9mm, and be highly 2-5mm.In Fig. 2, rubber grain 41 is set to cubic shaped, and magnet 42 is cylindrical shape, and magnet 42 is wrapped in rubber layer 4.

During concrete the use, the irony main body of adsorbable magnet will be set on special-shaped main body be adhered to, then the rubber layer with flexible LED display module of the present utility model simultaneously is attached on this irony main body, then sets power supply, and energising can make this flexible LED display module luminous.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
