Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, belong to the scope of the utility model protection.

It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment It is only used for explaining relative position relation under a certain particular pose (as shown in drawings) between each part, motion conditions etc., such as When the fruit particular pose changes, then directionality instruction also correspondingly changes therewith.

In addition, the description for being related to " first ", " second " etc. in the utility model is only used for describing purpose, without being understood that To indicate or implying its relative importance or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", At least one this feature can be expressed or be implicitly included to the feature of " second ".In addition, the technical side between each embodiment Case can be combined with each other, but must can be implemented as basis with those of ordinary skill in the art, when the combination of technical scheme Occur conflicting or will be understood that the combination of this technical scheme is not present when can not realize, also not in the requires of the utility model Protection domain within.

Referring to figs. 1 to 3, technical solutions of the utility model propose a kind of LED display 100, and the LED display 100 wraps Include flexible PCB (FPC；Flexible Printed Circuit), the flexible PCB is as the LED display 100 Mainboard 10.

FPC(Flexible Printed Circuit；Flexible PCB) it is using polyimides or polyester film as base material Manufactured one kind has height reliability, excellent flexible printed circuit.With Distribution density is high, in light weight, thickness of thin, The characteristics of bending property is good.Technical solutions of the utility model are by using FPC as mainboard 10 so that the LED display 100 has Flexibility, the body for being attached at people can be bent or be arranged on clothes.So that the LED display 100 turns into wearable portable Show product.

Wherein, the crooked radian of the mainboard 10 can reach 360 degree.

In the present embodiment, the mainboard 10 has two surfaces being oppositely arranged, and two surface is all provided with matcoveredn 11.

Wherein, the protective layer 11 is coated with Protection glue, fluid sealant etc. in mainboard 10.

Preferably, the protective layer 11 is polyurethane adhesive coating 11.

The technical program by mainboard 10 by being coated with polyurethane adhesive coating 11 so that the LED display 100 has preferable Preferable pliability while can arbitrarily bend, also the conducting that bending is not easy to LED is had an impact, namely be not easy So that the loose contact of circuit 50, can guarantee that LED display 100 can be with normal work.And two surfaces provided with the coating can also Slight waterproof.

Further, compared with prior art in irrigated the LED display 100 of fluid sealant waterproof and dustproof structure.This LED Display screen 100 generates heat smaller, and weight is lighter.

Preferably, the polyurethane adhesive coating 11 is polyurethane AB glue mixed coating.Because AB glue mobility is preferable, standing is It can cover automatically complete.

Further, surface of the LED display 100 provided with LED 30 needs large area to be coated with the polyurethane adhesive, the painting The thickness of layer is moderate, avoid it is blocked up cause to cover LED 30 surface influence display effect, it is excessively thin, LED 30 can not be covered and reached Less than waterproof effect and bulk strength.If the height of LED is 3mm, then the thickness of the polyurethane adhesive coating 11 should be less than 3mm, it is advisable using 2mm or so.

In the present embodiment, the LED display 100 includes some LEDs 30, if a surface of the mainboard 10 is provided with Dry mounting disc 12, a LED 30 are located at a mounting disc 12.

Wherein, the LED 30 can be paster LED lamp 30, or plug-in unit LED 30, can mount and the peace Sabot 12, it can also weld and the mounting disc 12.

It is to be appreciated that the LED display 100 also includes IC chip, the mounting disc 12 electrically conducts with the IC cores, its In, the IC chip is arranged at mainboard 10 and deviates from the surface provided with LED 30.And the mounting disc 12 can be it is circular, square or It is ellipse.

In the present embodiment, the LED 30 is in matrix arrangement, to meet the integrally bending radian of LED display 100 It is required that there is more preferable visual effect.

Wherein, an embodiment is enumerated：Matrix array structure by LED 30 using 48*16.

Further, it is 3~6mm by the spacing between two adjacent LEDs 30.Arranged for above-mentioned 48*16 matrix Spacing between array structure LED 30 is preferably by 5mm.

Yet further, the LED display 100 designs 768 LEDs 30.

It is comprehensive to cause the integrally bending radian of LED display 100 good and good visual effect.

In the present embodiment, the LED 30 may also be configured to three-color LED light 30.

It is to be appreciated that IC chip setting control of correspondent program LED 30 is shown, for example pictograph is shown, or even should The color that pictograph is shown can be with a variety of, and the three-color LED light 30 can show the light of seven kinds of different colours, seven kinds of lamps Light, which can coordinate, shows different effects.

Due to the bending of LED display 100 have to the electrode circuit 50 of mainboard 10 certain infringement, especially crooked radian compared with When big.In the present embodiment, reference picture 3, the technical program show the direction of routing of the electrode circuit 50 of mainboard 10 with the LED The axis of bending direction of display screen 100 be arranged in parallel, is along electrode circuit 50, electrode circuit when bending the LED display 100 50 are influenceed by bending, so as to have infringement to electrode circuit.

Further, each LED 30 includes pin, the orientation of the pin and the circuit direction of routing It is parallel.Certain IC chip, and the direction of routing of circuit 50 of other devices use the design method parallel with bending direction.

In the present embodiment, the edge of the mainboard 10 is provided with bound edge 40.The bound edge 40 is used to protect the edge of mainboard 10.

Preferably, the bound edge 40 uses flexible material, such as quality of rubber materials.So that the LED display 100 occurs It is hardly damaged during collision.

And because the mainboard 10 setting polyurethane adhesive coating 11 is by way of coating, surrounding glue can overflow loss, Using the bound edge 40 is set, glue spilling is also prevented from.

In the present embodiment, at the uniform velocity using S-shaped revolution dispensing when coating polyurethane adhesive so that coating is evenly distributed.

Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
