Abstract

The utility model relates to an LED display screen, which belongs to the technical field of display screens and is formed by splicing at least two LED display modules. The utility model is characterized in that the LED display module comprises a base plate, a face shield, a PCB plate and a fixing splicing device, and the fixing splicing device is disposed on the outer surface of the base plate; the mutually spliced LED display module is also provided with a rotating splicing device which comprises at least one set of detachable hinge; hollow structures are correspondingly disposed on the base plate, the face shield and the PCB plate, and the face shield is transparent. The utility model is advantageous in that the LED display screen does not adopt unit casing to perform mounting, thereby the structure is simple, light and thin; the rotating splicing device and the fixing splicing device are utilized in mutual combination, thereby the mounting, dismounting and maintenance of the LED display module are more convenient and fast, and the LED display screens in different planes and curved surfaces can be spliced; hollow structures are correspondingly disposed on the base plate, the face shield and the PCB plate, thereby the light transmission of the LED display screen is improved.

Description

A kind of LED display

Technical field

The utility model belongs to the display screen technology field, relates in particular to a kind of LED display.

Background technology

At present,, show the LED display that module is spliced, be widely used in being used to transmit various information in the advertising medium of public arenas such as meeting room, station, square by LED along with the application of large tracts of land video wall.But, most of LED display all are made up of unit box, have sealing, heavy, opaque, shortcoming such as maintenance difficulties is big, the plane that makes up or curved surface are single, glass curtain wall of building in a lot of occasions such as high-altitude and irregular curtain wall etc. just seem very inapplicable.Therefore, this just presses for a kind of frivolous, printing opacity, simple in structure, easy accessibility, and can present the LED display of various planes or curved surface, thereby realizes LED display and all-environment perfect adaptation.

The utility model content

The technical matters that the utility model mainly solves provides a kind of simple in structure, frivolous, printing opacity, perfect heat-dissipating, easy accessibility, and can present the LED display of various planes or curved surface.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED display is provided, show that by at least two LED module is spliced, described LED shows that module comprises base plate, face shield, pcb board and fixing splicing apparatus, described pcb board is arranged between base plate and the face shield, pcb board is provided with LED lamp and driving element, fixedly splicing apparatus is arranged on plate outer surface, also be provided with the rotary splicing device between the LED of the splicing demonstration module mutually, described rotary splicing device comprises at least one group of detachable hinge, the LED that every combined page is arranged on mutual splicing respectively accordingly shows on the base plate of module, described base plate, all be provided with engraved structure on face shield and the pcb board accordingly, described face shield is a transparent face mask.

The beneficial effects of the utility model are: because LED display described in the utility model does not adopt unit box to assemble, so structure is simpler, and is more frivolous; The rotary splicing device of detachable hinge-type and the fixedly splicing apparatus use that mutually combines have been adopted, make LED show that assembling, dismounting and the maintenance of module are more convenient, and the LED display that can splice various planes and curved surface, improve the screen shape controllability of LED display, widened range of application; Correspondence position all is provided with engraved structure on base plate, face shield, the pcb board, and face shield adopts the transparent material preparation, has not only alleviated LED and has shown the weight of module, and improved the light transmission of LED display.So the utility model LED display can with various environment perfect adaptations.

Embodiment

By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

Embodiment as the utility model LED display, see also Fig. 1 to Fig. 4, LED display shows that by at least two LED module is spliced, present embodiment is 4, described LED shows that module comprises base plate 1, face shield 2, pcb board 3 and fixing splicing apparatus 4, described pcb board 3 is arranged between base plate 1 and the face shield 2, pcb board 3 is provided with LED lamp 31 and driving element, fixedly splicing apparatus 4 is arranged on base plate 1 outside surface, be used for LED display is fixed on the exterior wall of various buildings, also be provided with rotary splicing device 5 between the LED of the splicing demonstration module mutually, described rotary splicing device 5 comprises at least one group of detachable hinge, present embodiment is two groups, every combined page is arranged on the upper and lower of the LED demonstration module base plate 1 of mutual splicing respectively accordingly, described base plate 1, all be provided with engraved structure 6 on face shield 2 and the pcb board 3 accordingly, present embodiment is a bar shaped engraved structure 6, described face shield 2 is a transparent face mask, because base plate 1, engraved structure 6 corresponding settings on face shield 2 and the pcb board 3 are advanced indoor so outdoor light can pass engraved structure 6 irradiations.

In addition, described face shield 2 can also be provided with reference column and be used for the projection 21 of LED lamp 31 on the ccontaining pcb board 3, correspondence position is provided with the pilot hole that matches with described reference column on described pcb board 3 and the base plate 1, after reference column passes above-mentioned pilot hole, positioning plate 1 and face shield 2 well, and pcb board 3 is embedded in the base plate 1, described projection 21 sides also can be provided with engraved structure, are used for the LED lamp and dispel the heat better.Described in the present embodiment fixedly splicing apparatus 4 can adopt following structure, specifically see Fig. 4, comprise splicing pickup groove 41, latch 42 and snak link 43, latch 42 is arranged in the splicing pickup groove 41, and can move along splicing pickup groove 41, snak link 43 matches with latch 42, just can Fixed latches 42 when snak link 43 is depressed, described splicing pickup groove 41 and snak link 43 are made by metal material, and latch 42 is made by metal or plastics.
