Outdoor Large LED Screen Installation Requirements
- Jan 06, 2018 -

LED screen have more types , according to the use of the environment can be divided into indoor and outdoor screen two. Indoor led screen and outdoor LED screen vary greatly. The first is the brightness is different, the brightness of the indoor screen to be several times lower than the outdoor screen to dozens of times; the indoor screen on the outdoor as the TV on the same brightness is not enough. Therefore, the outdoor screen must use ultra-high brightness LED, and in order to further increase the brightness and increase the visual distance, often in a pixel to encapsulate more than one high brightness LED. Second, the outdoor screen must be protected against rain, water, direct sunlight, dust, heat, wind, lightning and other indoor screens are not required to consider these issues.

At present, the main problems of the outdoor screen are as follows:

1. The screen is installed outdoors, often sun and rain, wind and dust cover, poor working environment. Wet or severely damp electronic devices can cause short circuits and even fire, triggering a fire or even a fire, resulting in a loss.

2. The screen may be affected by lightning strong electric magnetic strikes.

3. Ambient temperature varies greatly. The screen itself will have to produce a certain amount of heat, if the ambient temperature is too high and poor heat dissipation, the integrated circuit may not work properly, or even be burned, so that the display system does not work.

4. Audience wide, line of sight requirements far, wide field of vision. Ambient light varies widely, especially when exposed to direct sunlight.

Solutions and application requirements:

1. The combination of screen body and screen body and building must be strictly waterproof and leakproof. Screen body to have good drainage measures, in the event of stagnant water can be discharged smoothly.

2. In the screen and buildings to install lightning protection device. The screen body and the shell maintain a good grounding, grounding resistance is less than 3 ohms, the lightning-induced high-current discharge in time.

3. Install ventilation cooling, the screen body temperature between -10 ℃ ~ 40 ℃. Behind the screen body installed axial fan, discharge heat.

4. Use the working temperature -40 ℃ ~ 80 ℃ between the industrial integrated circuit chip, to prevent the winter temperature is too low to make the screen can not start.

5. In order to ensure long-distance visibility in the case of strong ambient light, you must use ultra-high brightness light-emitting diodes.

6. Display media selection of new wide viewing angle tube, wide viewing angle, pure color, consistent coordination, life expectancy more than 100,000 hours. The outer package of the display media is the most popular square cylinder with occlusion at the moment, sealed with silicone and without metal assembly. Its exquisite appearance, durable, with direct sunlight, dust, water, high temperature, anti-short circuit and other characteristics, the industry was called five anti-defensive.
