The main problems of outdoor full -color LED display are as follows
(1) The outdoor temperature changes greatly. When the display is working properly, it will generate a certain amount of heat. If it encounters high temperature weather, the heat dissipation effect is poor, and the integrated circuit will have abnormal work. Use again;
(2) The outdoor LED display will be affected by the brightness of the solar light, and there are some requirements for the brightness of the display screen.
(3) The installation environment of the outdoor LED display is generally large, because the display screen faces the audience, the visual distance must be appropriate.
(4) The full -color LED display is installed outdoors, and the ability to adapt to the environment is much higher than the indoor LED display. The outdoor environment and weather changes are diverse. The display screens are often blown by the wind and sun, and the working environment is relatively bad. Once the electronic equipment in the display is wet or exposed to high temperature, it will cause a short circuit of the line.
(5) In the summer thunderstorm, the display will be caused by the electromagnetic shock caused by lightning, so the lightning protection measures must be proper;
For the above special requirements, the outdoor full -color LED display must be done:
(1) Engineers need to calculate a full -color LED display based on the environment and viewing distance, so as to achieve the best display effect;
(2) In order to ensure that the environmental light is strong, it is necessary to watch at a long distance, and the diode of the super high brightness is needed;
(3) Install the lightning protection device on the full -color LED display. The main body and the box are kept well grounded, and the ground resistance should be less than 3?, So that the current generated by lightning is released in a timely manner;
(4) In terms of chip selection, choose industrial and integrated circuit chips between minus 40 degrees Celsius to 80 degrees Celsius to prevent the display from using the area with low environmental temperatures;
