Description
Technical field
The utility model belongs to the technical field of led display devices, especially belongs to the technology neck of small spacing led display devices
Domain, is related to a kind of led display devices.
Background technology
In recent years, small spacing LED display demand was in explosive growth, resolution ratio, contrast to led display devices
The important optical properties such as degree, visible angle and color uniformity are put forward higher requirements, and spacing is smaller, the resolution ratio of unit area
Bigger, display image is more clear, it is necessary to uses the led lamp beads of smaller.Led lamp beads are smaller, and single lamp bead institute is attainable steady
It is qualitative poorer, easily it is affected by, moisture-proof, windproof, rain-proof, anticorrosive, heat dissipation and uvioresistant etc. are all got over
To be more difficult to the requirement for meeting normal use；When carrying, installing with using, lamp bead crash rate is consequently increased.
At present, led shows that industry generally protects lamp bead using above lamp group by the way of covering mask, has on the mask
A series of lamp holes identical with the matching of lamp bead size, quantity, by the way that each lamp bead is buckled in the lamp hole of mask, realize mask
In pasting with fixing for lamp group surface.However, since mask is to be covered on by lamp hole buckle lamp bead above lamp group, led is shown
Often there is the phenomenon for hitting lamp, bad lamp in device, this phenomenon is especially prominent in small spacing led field of display devices.In maintenance, and need
The mask being buckled in above lamp group is removed, easily produces dead lamp, lamp bead comes off problem, causes lamp bead secondary damage, even more
The bad lamp phenomenon of large area, repair it is fairly cumbersome, this become small spacing led display devices use with faced in maintenance one
Hang-up.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of led display devices, it is provided in particular in small a kind of
Away from led display devices, which can be that led display modules or led show babinet or led display screens.The display device
It is obviously improved in moisture-proof, windproof, rain-proof, anticorrosive, heat dissipation with uvioresistant etc. performance, can substantially reduces display device
Bad lamp, hit lamp rate, in later period maintenance, can effectively avoid lamp bead come off and other infringement lamp bead phenomenons generation, and tie up
It is easier to repair program；It can better control over and adjust again at the same time the contrast, visible angle and uniform in color of led display devices
Degree.
In order to solve the above-mentioned technical problem, the led display devices of the utility model include bottom case, electronic component, circuit
Plate, LED lamp group, and mask is not pasted above LED lamp group, cure being fixed on embedding above the LED lamp group of circuit board
Resin bed, curing resin layer top are covered with light-transmissive film, and curing resin layer becomes protective layer jointly with light-transmissive film.
The bottom case is built-in with receiving, the cavity of fixed electronic component, further includes the fixed support structure of circuit board.
The circuit board is PCB circuit board or is fR4 circuit boards.
The LED lamp group is fixed on PCB circuit board front using SMT patch packaged types or is consolidated using COB packaged types
Due to FR4 circuit boards front.
The curing resin layer is heated obtained by fusing for sealed transparent material and acrylic polymers, thickness 0.5-1mm, thoroughly
Light rate is 50-90%, and hardness is Shao A65。- Shao A75。, it is attached to LED lamp group front.
The printing opacity film thickness is 0.05-0.1mm, and light transmittance 50-55%, is attached on curing resin layer.

Reference numeral:
1 it is bottom case, 2 be circuit board, 3 be LED lamp group, 4 be curing resin layer, 5 is light-transmissive film.
Embodiment
As shown in figure 3, the led display devices of the utility model include bottom case 1, electronic component, circuit board 2, LED lamp group
3rd, curing resin layer 4.Traditional led display devices can all cover mask above LED lamp group, so have to 3 surface of LED lamp group
Certain protective effect, but the led display devices of the utility model break through Traditional Thinking, in 3 surface of LED lamp group not covering surface
Cover.LED lamp group 3 is fixed on the top of circuit board 2, the embedding curing resin layer 4 above LED lamp group 3, the top of curing resin layer 4
Cover light-transmissive film 5.
As shown in figure 3, led display devices include bottom case 1, electronic component, circuit board 2, LED lamp group 3, curing resin layer
4 and light-transmissive film 5.Electronic component is fixed and terminates in 1 inner cavity of bottom case, which uses PCB circuit board or FPC circuit boards, will
LED lamp group 3 is fixed on PCB circuit board front using SMT patch packaged types, and encapsulation is fixed with to the circuit board water of LED lamp group
It is flat on in the corresponding mould of circuit board size, sealed transparent material and acrylic polymers are heated high temperature to being fused into liquid
State, after stirring and evenly mixing, obtains fluid resinous biend；Fluid resinous biend is injected into mould, bondline thickness 1mm, then
Dry, toast and obtain the circuit board for being attached with curing resin layer 4 and being fixed with LED lamp group, the light transmittance of the curing resin layer is
70%, hardness is Shao A70。, light-transmissive film 5 is attached on curing resin layer 4, which is 0.1mm, and light transmittance is
50%.By four pieces of above-mentioned packaged lamp groups, and the circuit board 2 of good attachment curing resin layer 4 and light-transmissive film 5 is spliced into led and shows mould
After group main body, it is fixed and is supported by bottom case, forms led display modules.Four pieces of above-mentioned display modules and bottom case are installed
Led show cases can be integrally formed, according to demand the sliceable led display screens for obtaining adult of size.
