[hard goods] LCD splicing screen installation skills and steps

The LCD splicing screen is not installed like an ordinary display device, but is simply installed and installed. LCD splicing screen installation should not only carefully choose the installation of the venue, but also need to pay attention to the light around the installation environment, but also pay attention to wiring, but also for the framework also has requirements, choose us to talk about how to install LCD splicing screen.

Method/step

Installation floor selection:

The installation surface of the LCD splicing screen should be flat, because the whole system of the LCD splicing screen is large in terms of volume and weight. The selected ground also requires a certain amount of capacity to withstand the weight. If the floor is a tile, it may not withstand its weight. Another point is that the installed floor should be able to prevent static electricity.

Cabling considerations:

When installing the LCD splicing screen, pay attention to separate the power line and the signal line during wiring, and install them in different places to avoid interference. In addition, according to the size and installation position of the screen of the entire project, the required lengths and specifications of various lines are calculated, and the needs of the entire project are calculated.

Ambient light requirements:

Although the brightness of the LCD splicing screen is very high, it is still limited, so the light surrounding the selected installation environment should not be too strong. If it is too strong, the screen may not be visible. The light (window) that may be injected near the screen may be blocked if necessary. At the same time, the light should be turned off when the equipment is running to ensure the normal operation of the equipment. Do not install the light just in front of the screen. Install the tube light.

Framework requirements:

In order to facilitate the maintenance of the LCD splicing screen in the future, the frame edging must be a detachable edging. In the outer frame, a gap of about 25mm is reserved along each side of the outer wall of the mosaic wall. The large-scale mosaic wall should also increase the margin appropriately according to the number of columns. In addition, in order to enter the box maintenance later, the maintenance access is in principle not less than 1.2m wide. The detachable edge strip is suitable for pressing down the edge of the screen by 3-5mm. After the box and the screen are fully mounted, the detachable edgebar is finally fixed.

Ventilation requirements:

In the maintenance tunnel, air conditioners or outlets must be installed to ensure good ventilation of the equipment. The position of the air outlet should be as far away as possible from the liquid crystal splicing wall (about 1m or so), and the wind at the air outlet can not be directly blown against the box, so as to prevent the screen from being damaged due to uneven cooling and heating.

At the construction site of liquid crystal splicing, installation and commissioning should be based on the phenomenon reflected by the fault to determine its cause. It is necessary to check the synchronization interface and transmission cable of the equipment, and the synchronization frequency range between the control signal source and the display terminal. If there is image ghosting, check if the transmission cable is too long or too thin. The solution is to change the line test, or increase the signal amplifier and other equipment.

If the focus is not ideal, you can adjust the display terminal. Faced with the emergence of problems, we must first learn how to analyze them so as to better solve the root causes of the problems. Through powerful analysis, we can shorten inspection time. These methods are all methods and techniques for debugging after installation. The installer must be skilled and professional. Only professional people can do professional things.

LCD splicing technology expertise

R & D and production of LCD splicing screen manufacturers know that the production process of industrial-grade LCD screen is much higher than the general display device. Even with the same panel level, the LCD splicing screen production requirements have to be more stringent. Although many security monitoring companies are now using LCD splicing screens, the understanding of LCD splicing screens is too simple, and the understanding of industrial-grade display devices is very simple.

In fact, at present, many LCD splicing screen construction companies do not meet the specifications for construction and selection, even if they choose foreign brands. Many large-screen display projects did not fully play the advantages of LCD splicing screens, and did not achieve HD effects, the smallest patchwork. From the microscopic point of view, more companies only know the installation, lacking the necessary knowledge to learn, LCD splicing screen manufacturers today to add some professional knowledge for everyone.

1. Contrast advantages of LCD splicing screen and other computer monitors

The liquid crystal splicing screen adopts the A-class liquid crystal panel, and the high reliability ensures the quality display. For the large screen, the role of the liquid crystal panel is undoubtedly the most important, which accounts for about 70% of the cost, and the general monitor selects the A-class panel. There will be increased production. At present, the LCD panel is divided into A+, A-, B+, and B-. The computer monitor selects the B+ panel very well, but the operating environment of the LCD splicing screen also determines the requirement of the LCD panel.

2, LCD splicing screen ultra narrow frame design

LCD splicing screen to frame, both sides of the slim design, the use of less than 1 mm cable, obviously better than the general display equipment BSV LCD splicing technology. It is bound to set off an upsurge of LCD seamless splicing in the monitoring field, which will create a "blowout effect" for market demand.

3, LCD splicing screen high resolution support point to point display

For the "other machines", the signal input processing chip is mainly used to work hard. Although the parameters shown can reach 1080P, it is not a full HD HDCP display, and its LCD is not a point-to-point horizontal direction by 1920. A vertical display panel of 1080 pixels

4, LCD splicing screen uses high quality electronic components (IC, capacitors, inductors, etc.)

The quality of LCD splicing products has a strict component selection system and a complete production line. Products from each production line are subjected to rigorous baking and testing. It is not like "other machines". The panel purchase time is very compact at the factory and the production assembly is free to leave the factory. Because "other machines" do not have inventory products, they must be assembled, produced, processed and installed for use by customers when they are delivered. The time is generally short. The quality of ICs, capacitors, and inductors is a direct influence on the life and safety of the monitor.

5, LCD splicing screen has a unique technology complementary to DNIEPro color and signal enhancement

For the liquid crystal display, the control IC for accurate control of color restoration can make the display effect of the liquid crystal display more colorful. Its control IC can filter out 1 billion of the best colors from about 68.6 billion colors, making it more accurate in reducing the color of objects. The general display signal board simply decodes the signal and displays it directly without IC processing.

6, LCD splicing screen has a dynamic enhanced signal to ensure the black and white sinking and dynamic smear phenomenon

The design and material selection of the display IC chip and control circuit are also very important. The first-tier manufacturers own the panel production line. The control circuit can be designed and developed from the most professional point of view. The use of materials and workmanship ensures that the large-screen display can be long. Stable time, at the same time, strengthen the processing of various types of input signals to ensure the effectiveness of grayscale.

7, LCD splicing screen uses advanced power supply DPMS

The DPMS management system maximizes power and signal boards to protect the LCD panel while reducing power consumption. The "lamp driver circuit" of the display, the high voltage bar is connected to the lamp inside the panel to light it and control its brightness. Therefore, the brightness of the display is mainly related to the number of tubes placed in the panel. The more the number, the higher the brightness.

For “other machines”, the CCFL lamps in the panel are all driven to light up, so that the display can work long hours with high brightness and the long-term heating seriously depletes the life of the panel, and why the LCD splicing screen is called a low thermal energy panel, The secret is not on the LCD panel, but the driving of the motherboard using the chip on the CCFL tube inside the panel can automatically change the light.
