Description
Technical field
The present invention relates to a kind of LED display module, more particularly to a kind of checkerboard can be bent in space curved surface, turn round
Bent LED display module, can repeat to install and use, withdraw from resilient after external force.
Background technology
In the prior art, the LED of large format shows that curtain wall is formed by several LED display module group assemblings, institute
It states LED display module and mainly divides following a few classes：
1) box-type：Installation will be arranged in a matrix on circuit boards to form numerous LED light of picture element, circuit
LED light control and driving chip are also equipped on plate, these components form an electric appliance together with the printed circuit on circuit board
Unit, then the electric appliance unit (being in fact exactly one piece of circuit board as computer main board) is installed to a semi-enclosed gold
In category or plastic casing.The main function of the metal or plastic casing be in order to protect foregoing circuit plate in the case where being subject to external force,
Detonator circuit failure when will not distort generation structural deformation because squeezing, while also play the housing in above-mentioned metal or plastic casing
Upper setting is assembled into the effect of the mounting structure needed for more large format screen (also known as LED shows curtain wall), such as sets screw hole, hangs
Hook etc..Above-mentioned circuit board, metal or plastic casing and disengaging signal, power cord etc. just constitute one similar to box-type
LED display module.
The installation of numerous box type LED display screen modules is fixed in structure (being usually bulky steel structure frame) to be formed
The LED of large format shows curtain wall.
2) grating type：Above-mentioned box type LED display screen module is heavier in itself and not penetrating, by a combination thereof installation
LED display curtain is one piece of huge whole plate, not only heavy but also stuffy room without ventilation, therefore, occurs a kind of LED display of grating type in row
Module.
It is mounted on numerous LED light on the circuit board of fine strip shape, then circuit board is embedded in the metal or plastics of U-shaped
In slot, a kind of unit lamp bar is formed, plurality of cells lamp bar by required design is equidistantly lined up and is installed to a rigid frame
On frame, regularly arranged LED light and regularly arranged lamp bar form the pixel being arranged in a matrix in lamp bar.Usually by LED
Lamp controls and driving chip circuit board is arranged on the middle part of lamp bar or the driving structure body at both ends, then from lead-out wire thereon
Road is to control and drive the LED light in lamp bar.
Above-mentioned LED light bar, driving structure body are fixed on formation grille type LED display screen module on rigid frame.
It can be seen that this module removes lamp bar, driving structure body and unit framework, other parts are penetrating, just as a rectangle
Shutter.It is equipped on rigid frame by the screw hole of the module assembling combination, hook etc..
It (is usually bulky steel construction that the installation of numerous grille type LED display screen modules, which is fixed on large-scale rigid structure,
Frame) formed large format LED display curtain.
3) LED module combined type LED display screen
Each picture element is mounted directly to one by one on the carriers such as metope, billboard, form picture element is containing LED
The module of lamp, module described herein are the set of LED light, circuit board and chip, are the electric appliance unit of small size same specification,
The electric appliance unit is fixedly arranged in a small plastic box or is directly encapsulated into transparent plastic article, each module is only a pixel
Point is connected with signal and power supply cable between them.Such as a kind of billboard screen, it is exactly in one piece of advertisement with picture
Many holes are regularly beaten on board, then will be exposed in this kind of LED module clump hole, on daytime, it is seen that being opened up on billboard
The pattern shown, these LED modules exposed of night lighted under the control of signal to be formed picture element one by one be combined into it is various aobvious
Show content.
In general, it is far below using the resolution ratio of the LED display curtain of this kind of module composition by aforementioned two kinds of LED display moulds
The resolution ratio for the LED display curtain that group is formed.The reason is that one piece of high-resolution screen has more than million picture element, this
It is too waste of manpower really kind to be mounted directly method, at present also one method is：It is initially formed fritter and contains regularly arranged perforation
LED module unit, then several such unit combination installations are formed into large screen, the purpose is to reduce on-site installation work
Amount.
The benefit installed using picture element one by one is can be as installation site arbitrarily changes, such as occasions such as curved surface, because
It is the electric wire that can be arbitrarily bent between LED module, unlike aforementioned two kinds of LED display modules, if curved surface to be completed
Module must be manufactured curved surface in itself, be unyielding in itself because they are all rigid bodies.If using advance
It forms fritter and contains regularly arranged perforation LED module unit, be combined into large screen, then the speciality of its arbitrary surface variation
It has been do not existed that, because becoming rigid element after being mounted to unit in advance yet, no longer can arbitrarily be bent, distort, if you need to be bent,
It must be prefabricated by size in advance.
Above-mentioned several modules are both needed to be mounted on rigid objects.Thus, the construction or erection of a LED display curtain
It is required for building a rigid body structure surface or frame in advance.If scaffold, skin, glass curtain in construction site
Large display screen is built or set up to wall etc. just to be needed to destroy original structure to adhere to the display required rigid structure of screen, such as
Fruit on skyscraper or glass curtain wall surface, this reformed into take, the engineering that expense is huge, while destroy original building, such as
Fruit is the display screen used temporarily, has thus reformed into the project to lose more than gain.
4) the LED combination display screen described in my utility model patent ZL2013200331378
It uses LED display module to be directly bonded on attachment (such as slippery walls and glass curtain wall) and forms large-size screen monitors
Curtain, this mode are using reducing the workload that punching or bolt are installed by the way of bonding installation, if to form big face
The high-resolution screen of product, workload or huge to can not complete, and manually installed, each LED display module in scene
Between clipping room away from being also difficult to accurately hold, meanwhile, the form of this individual module combination is limited by the electric properties such as chip
Restriction, the overall brightness of screen is also difficult to improve at present, so being all the low-light level screen that can not be used daytime.
5) my another utility model patent ZL2012200599349《Combination, the tensioning of suspension LED display, bundle
Tie up connection structure》
It is that LED module or lamp bar are mounted on component units display screen on the unit grid body of reticular structure (to be equivalent to
LED display module) recombinant is installed in large-scale network and forms large screen, while my utility model
201220127867X《The tight formula LED combination display screen of tensioning》It is that will uniformly be inlayed on netted substrate made of light material
Embedding LED display module (being equivalent to LED display module), which is hingedly connected to again on the large-scale reticular structure being made of rope, to be formed
Large screen.Although both LED display modules with certain permeability, also fail to break away from module be one itself cannot
The yoke for the rigid body being arbitrarily bent is that can not install realization in complex-curved, small curved surface, the particularly occasions such as space curved surface
, while its installation fixed form quantities is larger.
Pass through the above-mentioned analysis to LED display, it has been found that the hermetic type of LED screen module either box-type, still
Grid-like, latticed permeability, they are all the rigid bodies that itself cannot be bent under external force, once it is bent by external forces
It will result in structure and circuit damage, while install that their structure is all heavy and that precision prescribed is higher is big for combining
Type structure.In a manner that LED module is mounted directly as picture element or workload is huge or be pre-assembled to module
Unit and become heavy not penetrating, while this circuit-mode its electrical property, brightness are also undesirable.
