Instant open and immediately closed, so the impact on the display screen is great, simply due to the impact of large voltage and damage to the screen.
2、 Ambient temperature
When the ambient temperature is too high or the heat dissipation condition is not good, pay attention not to open the screen for a long time; The screen should be installed in the temperature scale environment of – 10 ℃ ~ 40 ℃. If it exceeds the temperature scale, temperature control equipment should be installed. It is forbidden to install the LED display near any heat source.
High ambient temperature or poor heat dissipation conditions lead to the life reduction of LED display.
3、 Environmental humidity
When the display screen is installed, the relative humidity of the environment should be 30% – 70%. When the indoor humidity is lower than 30%, static electricity simply occurs; When the indoor environment humidity is higher than 70%, the lamp will be affected with moisture.
4、 Corrosive gas environment
Please do not install the display screen in the corrosive gas environment containing acid or alkali components, such as near the chemical storehouse and indoor swimming pool (users are advised to stick the screen on the outside if necessary).
