1. The difference between motherboards
Display the difference of the motherboard, the driver motherboard of the splicing screen is more important and better at handling dynamic images. Since the start-up time of the liquid crystal display usually does not exceed 8 hours, it uses a civilian-grade display motherboard, and the large LCD splicing screen has to withstand the part-time load of 24 hours a day, 365 days a day, so a professional monitoring motherboard must be used to ensure higher brightness Contrast clarity, super high temperature resistance, etc. Thereby reducing the application loss of the screen. If an ordinary display is used for a long time, its brightness and contrast will drop quickly, affecting its application life. This is why most LCD monitors can usually display images after the project is debugged, but some screens will become dark after a period of continuous startup.
2. Cost difference
There is a certain cost difference between ordinary DID LCD splicing and LCD display. Most professional DID splicing screens use metal casings, brand new A+ industrial LCD screens and professional monitoring and driving motherboards, so the cost is much higher than the display. Many low-cost LCD splicing products on the market are actually modified from displays. Basically, it can be said that the display forms the shell, and even the old screen can be used.
Third, the perspective difference
The large viewing angle of the DID liquid crystal splicing can reach 178 degrees, while the ordinary liquid crystal can only see the blank in the direction of 178 degrees. This is a very important criterion for distinguishing large LCD panels from LCD panels. The input signals of the two are also different. Mosaic screen is important to input video signal. In order to meet the interface requirements of different front-end equipment, splicing will have more interfaces than displays. For example, Boqi Technology LCD splicing screen products have BNC, VGA, RGB, HDMI, DVI and other interfaces to meet the input requirements of differential signals. The monitor must input VGA signal, and the interface must be VGA, which cannot meet the signal input requirements of various monitoring equipment.
Fourth, the difference between LCD panels
From the perspective of LCD panels, LCD displays are used for civilian displays, while ordinary DID LCD splicing screens use high-brightness industrial A+ LCD panels, which require a higher backlight than displays. Therefore, when liquid crystal displays are weak on the display screen, they cannot obtain good image effects.
