Just like man is composed by various kinds of organs, the LED display screen is also consisted of many parts. As the modular design, the basic modular unit of the LED display screen is the LED cabinet. In other word,s the LED cabinet itself could be treated as a small size LED display. Being modular in nature, the cabinets are attached to each other like tiles to attain the required size of the display. Generally speaking, a regular LED display cabinet is consisted of six major parts:

• The LED modules type generally includes DIP and SMD LED modules, the pixel pitch usually ranges from 1mm to 50mm. The smaller the pitch, the shorter the viewing distance, and the higher resolution per SQ.MTR. The DIP type LED modules are usually used to the application of outdoor environment, and the SMD type modules are mostly used to the indoor application however it’s not absolute.
• Firstly the “LED cabinet” we mention here is just the “frame” to “hold” all the parts. It is one part of the “finished LED cabinet”.
  Usually we have two kinds material of LED cabinets, they are steel plate and aluminum plate. We can use the two kinds of material to manufacture different types of cabinet, such as simplified cabinet, standardized cabinet, curved cabinet, circular cabinet, double door cabinet, playground perimeter screen cabinet, lifting cabinet, front open cabinet, double front open cabinet etc. These cabinet can be customized according to your actual project condition and you requests.
• Power Supply Units. It includes different specs to suit different working temperature as well.
• Control System (Sending card and receiving card). We only use trusted brands such as LINSN, NOVA, DBSTAR etc. We will equip your LED display screen with proper cards according to your actual project condition and your requests.
• The power wire and ribbon cables are connected between the LED modules, power supply units, cooling fans and control cards.

The viewing angle of SMD LED display screen is about 160°(H)/120°(V) when the DIP LED display screen is about 110°(H)/60°(V). So for indoor LED display screens, we usually choose SMD type LED display screen for a wider viewing angle. But for outdoor LED display screen we usually choose DIP type LED display screens for its durable performance. When we want both wider viewing angle and good weather resistance capability, the same can be designed as required.

The value of best minimum viewing distance is determined by the value of pixel pitch, unit is Meter. For example, the best minimum viewing distance of P10mm LED display screen is around 10 meter, while the best mininum viewing distance of P16mm led display screen is around 16 meter.
This is a standard criteria while the same varies a little for different people.

1) Owing to the LED display screens are installed outdoor, working environment is very harsh, they often exposed to the sun and rain, and can’t avoid the wind erode and the dust cover, once the electronic equipment is wet or serious moisture will cause a short circuit or even fire, resulting in a big loss, so when install the led display, the led display screen body or the combination between the led screen body and architecture must be strictly waterproofing, also the screen body should have good drainage facilities.

2) The LED display may be attacked by lightning or affect by the strong electric magnetic, so it would be best to install a lightning arrested on the screen and the buildings. The led display screen body should keep a good grounding; let the current caused by lighting discharged in time.

3) The ambient temperature varies greatly. The led display screen works itself will produce some heat, if the ambient temperature is too high and the heat dissipation is bad, the integrated circuit may not work properly or even destroyed, such situation lead to the led display system may not work normally, so the led display screen should install the ventilation and the fans in each led display screen to exhaust the heat and to cool the temperature. Also the industrial-grade integrated circuit chips we adopted can work in temperature between – 40 ℃ ~ 60 ℃, in case the led display screen can’t be started in winter low temperature.

Comparing with traditional advertising media, LED digital signage have the following advantages:
1. The advertising on the LED screen is dynamic and constantly changing, so the audience would not feel bored when they watch the advertising program. People would like to stay for longer time to watch the vivid colors and beautiful images and videos.
2. Excellent convenience of program editing. During an advertising campaign, it is possible to correct and change the information instantly.
3. Though the advertising function of LED screen is great, the price is not high nowadays. And for the advertisers, the cost of advertising on LED screens is almost the same with traditional advertising billboards, but is much lower than Television and radio media.
4. The advertising on the LED displays is quiet and would not cause the boredom of the audience.
5. For the big companies, banks, publishing houses, casinos, hotels, entertainment complexes, the LED display attracts the interest in the promotion of their goods and services, and attract new customers to their offices.
