What You Should Know Before Buying A LED Display

Special requirements for outdoor LED display

• Screen and the Screen and the construction of the junction must be strictly waterproof leak proof; Screen to have good drainage measures in the event of a smooth water discharge;
  (2) In the screen to install lightning protection equipment and buildings. Display main body and cover good grounding, grounding resistance of less than 3 ohms, so that large currents
  caused by lightning discharge in time;
  (3) installation of ventilation equipment, cooling, so that the internal temperature of Screen -10 ℃ ~ 40 ℃ in between. Screen behind the top of the installed fan, exhaust heat;
  (4) selected working temperature between -40 ℃ ~ 80 ℃ industrial-grade integrated circuit chip, the winter temperature is too low to prevent the display cannot be started. ;
  (5) In order to ensure a strong ambient light in the case of remote visualization, high brightness light emitting diodes must be selected;
  (6) shows that media use the new wide viewing angle control, wide viewing angle, color pure, consistent coordination, life expectancy more than 100,000 hours. Shows the outer
  packaging for the media the most popular along the square tube with cover, silicone seals, no metal of assembly; its exquisite appearance, durable, with anti-direct sunlight, dust-proof,
  Waterproof, anti-high temperature, anti-short circuit "Five Anti" feature.

Which issues should be considered when you Design and install an outdoor screen?

The main issues of outdoor screen as follows:
(1) screen installed in the outdoors, often sun and rain, wind and dust cover, working environment. Electronic equipment is wet or damp can cause serious short-circuit or fire, cause failure or even fire, resulting in losses;
(2) The screen may be due to strong electric magnetic lightning attack;
(3) significant changes in ambient temperature. Display work itself must have some heat, if the ambient temperature is too high and heat it bad, integrated circuits may
not work correctly, or even destroyed, so that shows the system does not work;
(4) wide audience and, Sight Distance is far, wide vision requirements; ambient light changes, in particular, may be subject to direct sunlight.

What is the function of the power supply?

The working voltage of the LED is 5V DC, and the power we have is 220v 380v or 110v. AC.
Then need a device to translate it. The device we usually called power supply. The output of the power supply is 5V. About the input voltage, it has 220v, 110v...
So you do not need to worry that the screen cannot work in your country. Please just tell us the input power you use, and we can make the right power supply for you.
We usually use the brand of ChuangLian, sometime use MeanWell brand.
Usually the normal power supply can work under -20 centigrade. If you need your screen working under -30 or -40 centigrade, you need a special power supply.
We have this solution. Just let us know your special requirements.

What is DIP? And what is SMD?

DIP means double in line package, we call led lamp. SMD means surface mounted device.

What is the minimum resolution needed for a clear image in the video screen?

At least 50000 pixels.

Brightness requirements for different environment
The general brightness of the following:
(1) Indoor:> 800CD/M2
(2) semi-indoor:> 2000CD/M2
(3) Outdoor (look northward):> 4000CD/M2
(4) Outdoor (facing south):> 8000CD/M2

Is foreign language in the message display available?

Yes, using the scl2008, scl2005 (a kind of control card) can display any kind of language you want if you can type it on computer.

Standard resolution for each application
(1) text display: as the text size and differentiate to demand;
(2) ordinary video display: 320 × 240 matrix;
(3) digital standard DVD Show: ≥ 640 × 480 matrix;
(4) The full computer video: ≥ 800 × 600 matrix;

Wireless control available?

Yes, the wireless communication of asynchronous system can take by GPRS, RF (Radio frequency) and IR (Infrared ray). In the synchronous system, you can remote control the computer which connect with the led screen and that computer connect to the internet through wireless network.

There are many kinds of models, how can we choose? According to which item? (1) Visible distance; visible angles
(2) using environment; brightness, temperature, humidity...
(3) Display text? Picture? Or video?
(4) Screen mechanical installation and maintenance space;
(5) installation place, how to make maintain.
(6) The communication method we need between computer and the control card.
(7) Cabinet you need. Steel? Stainless steel? Aluminium? Standard water proof? None water proof? With flight socket? According to different application, using different cabinet

What is the main function of our display? Where need it?

If you cannot find your answer here, please ask our sales directly. They will give you professional answer.

What is the main function of our display? Where need it?
Main function: show message, Variable Message (Changeable Message). Show information by characters, picture and video.
This information can be stored in the memory of the control card (we called Asynchronous system), or on computer, the information is the same as on the computer
(We called synchronous system.)Can show video from TV, DVD player, video camera...
Full color display most used for Advertising, entertainment (back drop of pub, stage, concern.) stadium (perimeter adverting, real time score, highlight replay)
>Single and dual color display most used for shop, company logo, road information, bus station, rail way station, airport, subway, taxi, toll station.

In a word, where need show information (whether it is for adverting, entertainment, service...) to the audience, there need a led display.
