Abstract

The utility model relates to an SMD LED outdoor display screen which comprises a mask, a middle waterproof ring, a PCB with an SMD LED, a bottom shell and a waterproof ring which are subsequently fastened, wherein, high-transparent lens are lined on the front side of the mask; black decorative protruding bars are arranged between adjacent lens; three black sunshade blades with different size are arranged between every two longitudinal lens. According to the technical proposal, compared with the prior plug-in LED display screen, the LED display screen has the advantages of large display angle of view, high pixel density, high definition, light weight, simple production process, high enterprise efficiency, good consistency, easy detachment and installation, and good planeness.

Description

A kind of patch type LED outdoor display screen

Technical field

The utility model relates to a kind of LED outdoor display screen, relates in particular to a kind of outdoor display screen that the paster LED of encapsulating not directly is affixed on pcb board that has.

Background technology

Be subjected to the influence of traditional LED encapsulation, LED shows when module is used for the open air, can only make with the straight cutting fluorescent tube, and existing LED outdoor display screen adopts face shield+slotting lamp or paster lamp PCB+ encapsulating+drain pan+O-ring seal+casing.Make LED show that module must spend a large amount of manually going and insert lamp and encapsulating when producing, and because be subjected to the casting glue properties influence, make that the embedding consistance of each module is bad and pollute the LED surface, have influence on the luminous consistance of LED, thereby have influence on the display effect of LED.

Traditional LED outdoor display screen visual angle is little, and dot spacing is big, complex manufacturing and should not controlling, and module itself is heavy, is difficult to cleaning etc. after the surface is contaminated!

The bright content of utility model

The utility model corrects at above-mentioned problems, makes properties of product significantly improve, and production efficiency promotes greatly.

Concrete technical scheme is:

It adopts by the PCB of face shield, middle water proof ring, band paster LED, drain pan, the fastening structure that forms of water proof ring order.Utilize the face shield of the high grade of transparency of front to use paster LED, the water proof ring in the middle of adding realizes that paster LED applies to outdoor display screen.

The face shield explanation: there are high transparent lens in the front, and the prominent bar of decoration of black is arranged between the adjacent LED, and the luminous energy of LED is well launched; Three black sunshade leaves not of uniform size are arranged between per two vertical LED, utilize visual effect to make two adjacent face shields seem more smooth; Decorate prominent bar and can utilize view effect, effectively prevent the direct projection of sunshine, it is attractive in appearance that module is adorned.

The PCB of band paster LED: be that the paster LED of encapsulating not directly is affixed on pcb board,, single led taking up room dwindled greatly, can make like this that total is lighter, physical picture element resolution is higher owing to adopted the not paster LED of encapsulating.

Described drain pan is equipped with O-ring seal.

Adopt the LED display after the above technical scheme to have following significant technique effect than existing plug-in type LED display:

1。Display view angle is big; Make the outdoor screen of LED left and right sides visible angle increase near 160 degree, visible angle increases near 100 degree up and down, has improved image viewing effect up and down greatly;

2. picture element density is big, sharpness is high, can realize physical picture element resolution 〉=15625 points of outdoor display screen/every square metre;

3. product itself is in light weight;

4. production technology is simple, the enterprise efficiency height: plug-in unit LED changes paster LED into, and process for filling colloid into is saved, and makes that production technology is simpler, the production cycle shortens, weight is lighter, and in addition, the light-emitting area on plane has made things convenient for the surface clean of display screen.

5. the product unanimity is good;

6. be easy to the folding dress;

7. flatness is good.

Fig. 3 is the cut-away view of the replacement scheme 1 of the utility model embodiment;

Fig. 4 is the cut-away view of the replacement scheme 2 of the utility model embodiment.

Wherein: 1, face shield, 2, middle water proof ring, 3, the PCB of band paster LED, 4, drain pan, 5, water proof ring, 6, the sunshade leaf, 7, irritate Waterproof glue line, 8, O-ring seal.

Embodiment

Describe the utility model by the following examples, should be noted that, cited embodiment should not understand the restriction to invention.

As shown in Figure 1 and Figure 2: present embodiment is by PCB3, drain pan 4, the fastening structure that forms of water proof ring 5 orders of face shield 1, middle water proof ring 2, band paster LED.Utilize the face shield 1 of the high grade of transparency of front to use paster LED, the water proof ring 2 in the middle of adding realizes that paster LED applies to outdoor display screen.

Face shield 1 explanation: there are 256 high transparent lens in the front, and the prominent bar of decoration of black is arranged between the adjacent LED, and the luminous energy of LED is well launched; Three black sunshade leaves 6 not of uniform size are arranged between per two vertical LED, utilize visual effect to make two adjacent face shields seem more smooth; Decorate prominent bar and can utilize view effect, it is attractive in appearance that module is adorned.

The PCB3 of band paster LED: be that the paster LED of encapsulating not directly is affixed on pcb board,, single led taking up room dwindled greatly, can make like this that total is lighter, physical picture element resolution is higher owing to adopted the not paster LED of encapsulating.

As shown in Figure 3: the replacement scheme 1 of embodiment adopts directly the PCB3 of band paster LED is irritated Waterproof glue line 7 backs and drain pan 4 and the fastening structure that forms of water proof ring 5 orders.

As shown in Figure 4: the replacement scheme 2 of embodiment adopts the PCB3 and the drain pan 4 of beating O-ring seal 8, the fastening structure that forms of water proof ring 5 orders of face shield 1, band paster LED.

Obviously; foregoing is just in order to illustrate characteristics of the present utility model; and be not to restriction of the present utility model, the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
