Electronic equipment is wet or damp will cause a short circuit fire even serious, caused the fault and even fire, causing the loss of. So the combination part display screen and the screen body and building the purchase must be strictly waterproof and leakage proof; the screen body to have good drainage facilities, once the occurrence of water can smoothly discharge.
Outdoor LED wall screen may be affected by the strong electric magnetic attacks caused by lightning. So buy screen to install lightning protection apparatus in the display screen and the building. The display main body and the housing to maintain a good grounding, grounding resistance less than 3 ohm, high current lightning induced timely discharge
3.Heat resistance to low temperature
The temperature of the environment change greatly. Display work itself will produce some heat, if the ambient temperature is too high and the heat dissipation and the bad, the integrated circuit may not work properly, even burned, so that the display system can work normally; the installation of ventilation cooling equipment, the internal temperature of the screen body is between -10 to 40 DEG C. Behind the screen body is arranged above the axial flow fan, the heat discharge; selection of industrial grade integrated circuit chip operating temperature between -40 to 80 DEG C, prevent winter temperature is too low so that the display screen can not start

Chinese Institute of Metrology took accordance with the existing international standards, measured the bio-security of a p1.67 led display from both the blue light hazards to retina and the thermal hazards, and took comparison with a plasma TV and a LCD TV.
Test results show that, at the same brightness and white field conditions, although the peak brightness of the led display is higher than the other two samples in blue band, but its narrow band characteristics resulting weighted scored retinal hazard index not higher than plasma TV and LCD TV. The retina bio-security measured data has no significant differences between the three displays, the led display measurement results even better than the other two displays.
Whats should be keep in mind is that any display can cause permanent eye damage if keeping long-term view on the screen, thus, no matter what form of display is used, the audiences should pay attention to eye health and maintain good habits with the eyes.

How to Distingusih the LED Display Quality
Led display products is getting more and more popular for modern life, how to distingusih the led display quality? HSTV listed the following methods:

Surface flatness of the display should be within ± 1mm, so as to ensure the display image is not distorted. Partial raised or recessed will lead to the display viewing angle appears dead. The quality of flatness is determined mainly by the production process.
2. Brightness and viewing angle
Indoor full color screen brightness should be 800cd / m2 or more, outdoor full color screen brightness should be 6000cd / m2 or more, so as to ensure the normal operation of the display, otherwise the displayed image can't be seen due to low brightness.
3. The balance effect
White balance is one of the most important indicators of the display. Red, green and blue color science should take in the ratio of 1: 4.6: 0.16 in this way pure white is possible, if the actual proportion of any deviation occurs, the white balance bias. White balance is mainly determined by the quality of the display control system
4.The color reduction
Color reduction refers to the color display of color reduction. Display height should be consistent with the color of the playback source, so as to ensure realistic images.

How to get the most out of your LED screen?
Do you concentrate on your LED Screen? If you want to get the most out of your LED screen wall (and your customers), in terms of recognition from the audience, we will help you determine the best approach for creating a new ad.
Here we go with a few tips that might be useful for you (or your designer), when creating the next advertising to be broadcast on your LED screen wall. If you want to get the most out of your LED screen wall (and your customers), in terms of recognition from the audience, we will help you determine the best approach for creating a new ad.
First of all, let's address the ad duration. Some people make the huge mistake of creating 30 to 40 seconds ads. 30 seconds? Your audience is not sitting on a sofa waiting for the next TV show! They are most probably driving by at 45 miles per hour and hopefully they are more focused on the street rather than your LED Screen.Still, they should be able to see the entire ads, from start to end while passing by. So what's the point of creating a wonderful ad, if they can't read the advertiser's PHone number and address at the end because the ad is too long?
From my experience an ad should be a maximum of 10 seconds in length, and rarely 15 seconds.Longer ads are pointless because either your target sees the beginning and not the end, or vice-versa. In both cases, you didn't get the message across, and the audience did not find an interesting message on your LED wall.
Therefore your customer will have no interest in doing it again in the future because they didn't get much in return for their investment.Of course, there are exceptions to the "10 second" rule, such as when LED Screen walls are installed in pedestrian areas where people have more time to watch the LED screen wall. But as I said, those are exceptions and are rare.
