Release time：2018-12-05　 Read: 6361

The LCD splicing screen is not installed like an ordinary display device, but it is simply installed. The installation of the LCD splicing screen should not only be careful to choose the installation site, but also pay attention to the light around the installation environment, and also pay attention to the wiring, and also have requirements for the frame, choose. Let's talk about how to install the LCD splicing screen.

Method / step

The choice of installing the ground:

The installation surface of the LCD splicing screen should be flat, because the entire system of the LCD splicing screen is relatively large in terms of volume and weight. The selected ground also needs to have a certain ability to withstand weight. If the floor is tiled, it may not be able to withstand its weight. Another point is that the installed ground should be able to prevent static electricity.

Wiring precautions:

When installing the LCD splicing screen, be careful to distinguish the power and signal lines when 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, calculate the length and specifications of the various lines required, and calculate the needs of the entire project.

Ambient light requirements:

Although the brightness of the LCD splicing screen is very high, it is still limited, so the light around the environment where the installation is selected should not be too strong. If it is too strong, the screen may not be visible. Light that may be incident near the screen (such as a window), if necessary, should be blocked, and the light should be turned off when the device is running to ensure the normal operation of the device. Do not install the lamp in front of the screen, install the drum light.

Framework requirements:

In order to facilitate the maintenance of the LCD splicing screen in the future, the frame edging must be detachable. In the outer frame, a gap of about 25 mm is reserved on each side of the outer wall of the wall, and the large wall should also be appropriately increased according to the number of columns. In addition, in order to enter the cabinet maintenance later, the maintenance passage is in principle not less than 1.2m wide. The detachable side strip is suitable for pressing the edge of the screen by 3-5 mm. After the box and the screen are completely installed, the detachable side strip is finally fixed.

Ventilation requirements:

In the maintenance passage, air conditioners or air outlets must be installed to ensure that the equipment is well ventilated. The position of the air outlet should be as far as possible from the LCD splicing wall (1m or so is better), and the wind at the air outlet cannot be directly blown against the box to avoid damage to the screen due to uneven heat and cold.

In the LCD splicing construction site, the installation and commissioning should judge the cause according to the phenomenon reflected by the fault. It is important to check the synchronous interface and transmission cable of the equipment, and the synchronization frequency range of the signal source and the display terminal. If the image has a ghost image, check if the transmission cable is too long or too thin. The solution is to change the line test or add a signal amplifier or other device. If the focus is not ideal, you can adjust the display terminal. In the face of the emergence of problems, we must first learn to analyze, in order to better solve the root causes of the problem, through strong analysis, can shorten the inspection time. These methods are some methods and techniques for post-installation debugging. The installer must be skilled and good, and only professional people can do professional things.

LCD splicing technology expertise

Manufacturers of R&D and production of LCD splicing screens know that industrial-grade LCD screen production processes are much higher than general display devices. Even with the same panel level, LCD splicing screen production requirements are 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, many LCD splicing screen engineering companies currently do not meet the specifications for construction and selection, even if they choose foreign brands. Many large-screen display projects have not fully utilized the advantages of LCD splicing screens, and have not achieved high-definition effects and minimal seams. From a microscopic point of view, more companies only know about installation, and lack of knowledge to master the necessary knowledge. Today, LCD splicing screen manufacturers add some expertise to everyone.

LCD splicing technology expertise

1, the contrast advantage of LCD splicing screen and other computer monitors

The LCD splicing screen adopts the A-class LCD panel, and the high reliability ensures the quality display. For the large screen, the role of the LCD panel is undoubtedly the most important, which accounts for about 70% of the cost, while the general display selects the A-class panel. There will be an increase in production. At present, the LCD panel is divided into A+, A-, B+, B-, and the B+ panel of the computer monitor is very good, but the LCD splicing screen application environment also determines the higher requirements of the LCD panel.

2, LCD splicing screen ultra narrow frame design

LCD splicing screen to the frame, slim design on both sides, using less than 1 mm cable, significantly better than the general display device BSV LCD splicing technology. It is bound to set off a seamless liquid crystal splicing boom in the field of surveillance, which will form a "blowout effect" of market demand.

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

For "other machines", it is mainly in the signal input processing chip, the parameters shown can reach 1080P, in fact, not full HD HDCP display, its liquid crystal display is not the point-to-point horizontal by 1920, A display panel consisting of 1080 pixels in length.

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

The quality of LCD splicing screen products has strict component selection system and perfect production line. The products of each production line are subject to strict baking and testing. Unlike the "other machines", the procurement time of the panel is very compact at the factory, and the production assembly is ready to go. Because "other machines" do not have inventory products, they must be assembled into the panel for production, processing, and installation for customers. The time is usually very short. The quality of ICs, capacitors, and inductors is good or bad, which directly affects the life and safety of the display.

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

For the liquid crystal display, the control IC that restores the color precise control can make the display effect of the liquid crystal display more colorful. Its control IC is able to screen 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 motherboard simply decodes the signal and displays it directly, without IC processing.

6, LCD splicing screen with dynamic enhanced signal to ensure black and white color and dynamic smear phenomenon

The design and selection of the IC chip and control circuit of the display are also extremely important. The first-line manufacturers have their own panel production lines, which can design and develop the control circuit from the most professional angle. From the materials to the workmanship, the large-screen display can be long. Time-stabilized work, while strengthening the processing of various input signals to ensure the effectiveness of gray scale.

7, LCD splicing screen using advanced power DPMS

The DPMS management system enables the power supply and signal board to maximize the protection of the LCD panel while reducing power consumption. The "lamp drive circuit" of the display, the high voltage bar is connected to the lamp inside the panel to illuminate it and control its brightness. Therefore, the brightness of the display is mainly related to the number of lamps placed in the panel, and the greater the number, the higher the brightness. For the "other machine", the CCFL lamp that drives all the panels is illuminated, so that the display works for a long time with high brightness and the long-term heat is seriously depleted of the life of the panel, and why the liquid crystal splicing screen is called a low-heat panel. The mystery is not on the LCD panel, but the drive board uses the chip to automatically change the CCFL tube inside the panel.
