Outdoor LCD advertising machine has strong pertinence, high arrival rate, and can be accepted by consumers without being rejected. The development potential of outdoor advertising machine is huge. However, the erratic weather in the outdoor environment will always make the outdoor advertising machine undergo severe tests. The following Xiaobian will introduce the principle and maintenance knowledge of the outdoor advertising machine to work in high temperature and cold environments.
Zhongyu Display has a certain relationship with its design for the LCD advertising machine to work in an outdoor high and low temperature environment, which is mainly reflected in the design of the shell:
1. The thickness of the advertising machine casings we have seen is relatively thick. Generally, a casing with a thickness of more than 28cm is required. There must be a reason for such a thick casing. Because the outdoor environment is relatively harsh, this thick There is a protective advertising machine in the thick casing. Generally, the outdoor advertising machine is equipped with a high-power roller fan and an industrial air conditioner in the casing to dissipate heat, so the advertising machine can work at high temperature.
2. The LCD screen of the outdoor LCD advertising machine is also different. The high-brightness LCD screen is specially used for outdoor use. The outdoor high-brightness screen has the function of automatically adjusting the brightness. When the brightness reaches the highest or when the weather is dark, it can automatically adjust the brightness. Adjust the brightness to display, and in a low temperature environment, the chassis also has the ability to resist low temperature. In addition, the glass of the outdoor advertising machine is made of anti-glare AR glass, and the glass will not reflect light due to sunlight. It will also have the effect of concentrating light energy to generate temperature, and the power of the outdoor advertising machine is relatively large, and the operation of the machine will also generate a certain temperature. Air conditioning and heating modules.
Maintenance knowledge:
1. Keep the humidity in the environment where the outdoor advertising machine is used, and do not let anything with moisture properties enter your outdoor advertising machine. Applying power to an outdoor advertising machine that contains humidity can cause parts to corrode, which can cause permanent damage.
2. To avoid possible problems, we can choose passive protection and active protection, try to keep the items that may cause damage to the outdoor advertising machine away from the screen, and wipe the screen as gently as possible to avoid possible damage. Sex is minimized.
3. The outdoor advertising machine has the closest relationship with our users, and it is also very necessary to do a good job of cleaning and maintenance. Exposure to the outdoor environment for a long time, such as wind, sun, dust, etc., is easy to get dirty. After a period of time, the screen must be covered with dust. This needs to be cleaned in time to wrap the surface with dust-proof soil for a long time to affect the viewing effect.
4. It is required that the power supply is stable and the grounding protection is good. Do not use it in harsh natural conditions, especially strong lightning weather.
5. Metal objects that are easy to conduct electricity such as water and iron powder are strictly prohibited in the screen. The outdoor advertising machine should be placed in a low-dust environment as much as possible. Large dust will affect the display effect, and too much dust will cause damage to the circuit. If water enters for various reasons, please turn off the power immediately and contact the maintenance personnel until the display panel in the screen is dry before use.
6. It is recommended that the outdoor advertising machine rest for more than 2 hours a day, and the outdoor advertising machine is used at least once a week during the rainy season. Generally, the screen is turned on at least once a month, and it is lit for more than 2 hours.
7. The outdoor advertising machine needs to be regularly checked for normal operation and whether the line is damaged. If it does not work, it should be replaced in time. If the line is damaged, it should be repaired or replaced in time.
8. Non-professionals are not allowed to touch the internal lines of the outdoor advertising machine to avoid electric shock or cause damage to the lines; if there is a problem, please ask a professional to repair it.
