Description

A kind of pel spacing is 10.66 millimeters a LED display module

[technical field]

The utility model relates to a kind of LED display module, and the centre distance between especially a kind of pixel is 10.66 millimeters LED display module, belongs to the LED display field.

[background technology]

The range of application of large LED display screen more and more widely, it can be applicable to various occasions such as indoor outer advertisement, physical culture, traffic, performance, exhibition, rally, is enriching people's life and many facilities are provided.Yet existing LED display, the module that pel spacing is less often has the following disadvantages:

1, the module size because of LED display generally is difficult to do greatly, because less, the quantity of required LED display module is inevitable more, make the flatness of entire display screen be difficult to regulate, and the slit between each LED module is excessive.

2, it is less to resemble several spacings, and led light source is closeer, the light that led light source sends on each pixel be easy to by around led light source block, thereby influence whole display effect.

Above-mentioned deficiency normally causes the major reason of mosaic phenomenon.

[summary of the invention]

For solving above-mentioned deficiency, the utility model aims to provide a kind of flatness that can effectively improve LED display, strengthen the screen display effect, fundamentally eliminated mosaic phenomenon, making display effect a kind of pel spacing more bright-coloured, more true to nature is 10.66 millimeters LED display module.

For achieving the above object, the utility model is achieved through the following technical solutions: LED display module (P10.66) is made of face shield, drain pan, PCB lamp plate, PCB drive plate, waterproof apron, their assembly relation is: the PCB lamp plate is fixed on the drain pan with screw, be covered with face shield above the PCB lamp plate, the back of drain pan is lined with waterproof apron, at last the PCB drive plate is placed on the PCB lamp plate that is fixed on the drain pan.

Described face shield is that the pixel of offering some arranged on the rectangle cover is lit a lamp and emptyly constituted, and described picture element lamp hole is rearranged by particular order by three onesize lamp holes;

It is characterized in that: lamp hole is arranged evenly on the face shield, three lamp holes of each pixel independently separately, luminous between the led light source can not influence each other like this;

Its another feature is: the uniform striped in face shield surface, good looking appearance can be eliminated reflective phenomenon.

Described drain pan is rectangular, and there are the reinforcement of some even layouts and the fixing pillar used of PCB lamp plate and face shield in the centre,

It is characterized in that: the area of drain pan is bigger, can lay 24*24 pixel (at present industry in generally only done 16*8 picture element), makes the easier adjusting of flatness of whole LED display screen;

Its feature also is: drain pan the right and left is made corrugated limit, the position wall thickness of avoiding led light source is thicker, all the other positions are thinner, form corrugated limit continuously like this, the module big for area, that pixel is little, this " design on corrugated limit " improved the flatness of entire module greatly;

Its feature also exists: be provided with the reinforcement of some even layouts in the middle of the drain pan, such design has also improved the flatness of module greatly.

Described PCB lamp plate is formed by 24*24 picture element rectanglar arrangement, each pixel is made up of by specific configuration three primitive colours LED lamps, its feature also is: the centre distance on the PCB lamp plate between the pixel is 10.66 millimeters (between 10.6～10.7mm), this spacing belongs to initiative in the LED display industry, and it is place about 10 meters that product is suitable for viewing distance.

Described waterproof apron is a silicon rubber loop, has excellent waterproofness and serviceable life.

After adopting this programme, just can effectively improve the flatness of LED display, strengthen the screen display effect, fundamentally eliminate mosaic phenomenon, make display effect more bright-coloured, more true to nature.

Characteristics of the present utility model and advantage will be described further in conjunction with the embodiments by accompanying drawing:
