Manufacturers who develop and produce LCD splicing screens know that the production process of industrial grade LCD screens is much higher than that of general display equipment. Even at the same panel level, the production requirements for LCD splicing screens must be more stringent. Many large screen display projects have not fully utilized the advantages of LCD splicing screens and have not achieved high-definition effects, with minimal seams. Although many security monitoring companies are now using LCD splicing screens, their understanding of LCD splicing screens is too simple, and their understanding of industrial grade display equipment is very shallow. In fact, many LCD splicing screen construction and selection companies currently do not meet the standards, even if they choose foreign brands. From a micro perspective, more companies only know about installation and neglect to master necessary knowledge. Today, LCD splicing screen manufacturer Huabangying will supplement some professional knowledge for everyone. 1. The comparative advantages of LCD splicing screens compared to other computer monitors are that LCD splicing screens use A-grade LCD panels, which ensure high reliability and quality display. For large screens, the role of LCD panels is undoubtedly the most important, accounting for about 70% of the cost. However, choosing A-grade panels for general monitors may result in increased costs. At present, LCD panels are divided into A, A -, B -, and B -. Choosing B panel is a good choice for computer monitors, but the application environment of LCD splicing screens also determines that LCD panels have higher requirements. It is bound to trigger a wave of seamless LCD splicing in the monitoring field, which will form a "surge effect" of market demand. 2. LCD splicing screen with ultra narrow border design. LCD splicing screen without borders, slim design on both sides, using less than 1mm cable, significantly better than the BSV LCD splicing technology of general display devices. Every product on each production line undergoes strict baking and testing before leaving the factory. Unlike "other machines", the procurement time for panels is very tight when they leave the factory, and production and assembly are done arbitrarily before leaving the factory. 4. LCD splicing screen adopts high-quality electronic components (IC, capacitor, inductor coil, etc.). The quality of LCD splicing screen products has strict component selection system and perfect production line. Because 'other machines' do not have inventory products, they are assembled, processed, and installed for customer use only after delivery, and the time is generally very short. 5. The LCD splicing screen has the unique technology of DNIEPro color and signal enhancement complementarity. For LCD displays, the control IC that accurately controls the reproduction of colors can make the display effect of LCD displays more outstanding. IC、 The quality of capacitors, inductors, and coils directly affects the lifespan and safety of the display. Its control IC can select 1 billion optimal colors from approximately 68.6 billion colors, making it more accurate in reproducing the colors of objects. However, typical display signal motherboards simply decode the signal and display it directly without going through IC processing. 7. The LCD splicing screen adopts advanced power supply DPMS DPMS management system, which maximizes the protection of the LCD panel by the power supply and signal board, while reducing power consumption. The "lamp drive circuit" of the monitor is connected to the lamp inside the panel by a high-voltage strip to light it up and control its brightness. 6. LCD splicing screens have dynamic enhancement signals, ensuring the darkening of black and white and dynamic ghosting. The design and selection of IC chips and control circuits for displays are also extremely important. First tier manufacturers have panel production lines themselves, which can design and develop control circuits from the most professional perspective. From material to workmanship, it ensures that large screen displays can work stably for a long time, and at the same time, various input signals are strengthened to ensure the effectiveness of grayscale. For "other devices", the CCFL lamps inside the panel are all driven to light up, causing the display to work at high brightness for a long time and severely damaging the lifespan of the panel due to long-term heating. The reason why LCD splicing screens are called low thermal energy panels is not because of the LCD panel, but because the motherboard uses chips to automatically change the CCFL lamps inside the panel to light up.
