Generally, heat dissipation is a major factor that affects the lighting intensity of liquid crystal splicing system lamps. Generally speaking, according to the way of taking away heat from the radiator, the heat dissipation mode can be divided into active heat dissipation and passive heat dissipation. Active heat dissipation is to forcibly take away the heat emitted by the heat sink through heat dissipation equipment such as fans; The so-called passive heat dissipation means that the heat source of the large screen splicing light source is naturally distributed into the air through the heat sink, and the heat dissipation effect is proportional to the size of the heat sink. So how should we maintain the heat dissipation of the LCD splicing screen in the daily use of hot summer? Compared with traditional electronic products, the environment in which the high-brightness liquid crystal display screen is located is also complex and changeable. The use value of any electronic product is reflected in the long-term use process, it is not only necessary to pay attention to the methods and methods, but also to be diligent in the maintenance of the display screen to ensure the quality of the high-brightness LCD screen. Here, we will tell you how to maintain the highlight LCD screen! ? 1. Keep the humidity of the use environment of the high-brightness liquid crystal display screen. Although it is sometimes inevitably affected by the weather, the wind and rainy days have certain damage to its appearance, but if it enters the display screen, it will cause corrosion of some parts, which will cause permanent damage. No matter how good the advertising machine is, it will not be able to withstand scrutiny. ? 2. In order to avoid possible problems, stay as far away as possible from the items that will cause danger to the advertising machine. When cleaning the screen, it is also necessary to gently clean the screen. The mentality is also crucial. Patience and care will reduce the damage to a very low level. ? 3. It is required to have stable power supply, not to neglect charging in time, keep good grounding, pay attention to weather forecast, take protective measures before bad weather comes, and cut off the power supply to prevent damage. ? 4. The switching sequence of the highlight LCD screen :? A: turn on the control computer to make it run normally before turning on the highlight LCD screen. ? B: turn off the high-brightness LCD screen before turning off the computer. ? 5. It is recommended that the LCD highlight screen rest for more than two hours a day. The higher the power, the stronger the kinetic energy. If it has been used for a long time, the life will be shortened. ? 6. Regularly check whether the display screen is in working condition and whether the line is in good condition. If there are any abnormal problems, repair or replace them in time. ? 7. Do not play all-white, all-red, all-green, all-blue and other all-bright pictures for a long time, so as not to cause excessive current, excessive heating of the power cord, damage to the display screen lamp and affect the service life of the display screen. Do not disassemble or splicing the screen at will! ? 8. Highlight the internal line of the LCD screen, non-professionals are prohibited from touching, so as to avoid electric shock or damage to the line; If there is a problem, please ask a professional for maintenance. Method 1: keep the liquid crystal splicing screen ventilated and at normal temperature through ambient temperature control; You can use a fan or air conditioner to control the ambient temperature; Try to avoid the LCD splicing screen for a long time. Method 2. Regular inspection technicians check on time and regularly check the use of various display screens. If there is a good inspection habit, any quality problems can be eliminated in time and handled in the first place. It can also solve the problem of LCD splicing screen unit board failure caused by high temperature. Method 3: the use of heat-conducting materials the optional LCD splicing screen uses a more high-quality and durable heat-conducting material. The splicing screen not only saves maintenance, but also saves heat in time.
