LCD splicing screen has become an increasingly important component of the security monitoring system. As the splicing technology of liquid crystals continues to improve, its application will become more and more popular, the technology content will become higher and higher, and the functions will become more comprehensive and powerful. . After rapid development in recent years, LCD splicing screens have achieved a series of technological innovations such as ultra-thin, ultra-narrow, arbitrary splicing, and multi-layer roaming. Currently, the largest liquid crystal splicing unit on the market can reach 60 inches, and the volume Small and light, easy to install.
Splicing large screens as high-end display products on the market, providing perfect solutions for security monitoring in traffic safety, energy, power, and other fields, and satisfying the monitoring screen display in multiple industries and multiple fields. Application requirements.
From the point of view of long-term development of security monitoring, the security monitoring digitalization, dispatching automation, integration of information resources, and central control management of LCD splicing screens also provide a new development path for security monitoring.
The reason for the black screen is basically:
Power, adapters, boards, and the worst result screen is broken.
The first is to check the power: performance as pressing the panel button without any response, the indicator is off, first use a multimeter to measure the voltage, if no voltage or voltage becomes very low, then one may be a problem with the input stage of the power circuit, also That is to say, there is a problem with the point source. This kind of problem is very common, usually burn insurance or voltage regulator chip is faulty, and some of the machines use built-in switching power supply. Therefore, when we stop the LCD splicing screen, we must ensure that the voltage is stable! Another condition If the program is washed away, it may result in no booting. This is like our computer cannot be switched on. Sometimes it is the cause of the software. This requires us to purchase software.
The appearance of screen flashing on the LCD splicing screen is generally the following:
The power adapter is damaged, the power plug is unstable, the voltage is unstable, the vga line interface is not firm, or the cable is broken.
The solution is: re-connect the vga line, carefully refer to the product wiring instructions, according to the above instructions to seriously conduct the connection, the interface should be plugged in, to avoid short circuit or contact failure phenomenon.
Use a multimeter to test the internal connection lines of the LCD panel to find out bad or short circuits, and replace the high-quality circuit cable. Use a multimeter to check whether the power supply of the LCD splicing screen is grounded. The screen flicker may be caused by this reason. If there is a problem, ground the power supply.
