Method / step
selection of installation ground:
The installation ground of LCD splicing screen shall be flat, because the whole system of LCD splicing screen is relatively large in both volume and weight. The selected ground also needs to have a certain weight bearing capacity. If the ground is ceramic tile, it may not be able to bear its weight. Another point is that the installation ground should be anti-static.
Precautions for wiring:
when installing the LCD splicing screen, pay attention to distinguish the power line and signal line during wiring, and install them in different places to avoid interference. In addition, the length and specifications of various lines required shall be calculated according to the screen size and installation position of the whole project, and the needs of the whole project shall be calculated.
although the brightness of LCD splicing screen is very high, it is still limited after all, so the light around the installation environment should not be too strong. If it is too strong, you may not see the picture on the screen. The light that may enter near the screen (such as windows) shall be blocked if necessary, and the light * shall be turned off when the equipment is running to ensure the normal operation of the equipment. Do not install a lamp directly in front of the screen, just install a barrel lamp.
in order to facilitate the maintenance of LCD splicing screen in the future, the frame edge must be removable. About 25mm gap shall be reserved between the inner edge of the outer frame and the outer edge of the splicing wall, and the allowance shall be appropriately increased according to the number of columns for large splicing wall. In addition, in order to enter the box for maintenance in the later stage, the maintenance channel shall not be less than 1.2m wide in principle. The removable edge strip should press the screen edge for 3-5mm. After the box and screen are completely installed in place, * fix the removable edge strip.
air conditioner or air outlet must be installed in the maintenance channel to ensure good ventilation of the equipment. The air outlet shall be located as far away from the LCD splicing wall as possible (about 1m is better), and the air at the air outlet shall not be blown directly against the box to avoid damage caused by uneven cooling and heating of the screen.
at the LCD splicing construction site, the installation and commissioning shall judge the cause according to the phenomenon reflected by the fault, and focus on the inspection of the synchronous interface and transmission cable of the equipment, as well as the synchronous frequency range of the signal source and the display terminal. If the image has ghosting, check whether the transmission cable is too long or too thin. The solution is to change the line for test, or add equipment such as signal amplifier. If the focus is not ideal, the display terminal can be adjusted. In the face of problems, we must first learn to analyze in order to better solve the root causes of problems. Through strong analysis, we can shorten the inspection time. These methods are some of the methods and skills of installation and debugging. Installation personnel must be proficient, and only professional people can do professional things.
professional knowledge of LCD splicing technology
manufacturers who develop and produce LCD splicing screens know that the production process of industrial LCD screens is much higher than that of general display equipment. Even at the same panel level, the production requirements of LCD splicing screen should be more strict. Although many security monitoring enterprises begin to use LCD splicing screen, their understanding of LCD splicing screen is too simple, and their understanding of industrial display equipment is very simple. In fact, at present, the construction and type selection of many LCD splicing screen engineers do not meet the specifications, even if they choose foreign brands. Many large screen display projects do not give full play to the advantages of LCD splicing screen, and do not achieve high-definition effect, * small splicing. From the micro point of view, more companies only know the installation and lack the necessary knowledge. Today, LCD splicing screen manufacturers supplement some professional knowledge for you.
1. Comparative advantages of LCD splicing screen and other computer displays
the LCD splicing screen adopts A-level LCD panel with high reliability to ensure the quality of display. For the large screen, the role of LCD panel is undoubtedly * important, which accounts for about 70% of the cost. However, the selection of A-level panel for general display will increase. At present, the LCD panel is divided into a , a -, B , B -. It is good for the computer monitor to choose B panel, but the application environment of LCD splicing screen also determines the high requirements of LCD panel.
2. Ultra narrow frame design of LCD splicing screen
the LCD splicing screen has no frame, slim design on both sides, and uses less than 1mm flat cable, which is obviously superior to the BSV LCD splicing technology of general display equipment. It is bound to set off an upsurge of LCD seamless splicing in the monitoring field, which will form a "blowout effect" of market demand.
3. High resolution LCD splicing screen supports point-to-point display
for "other machines", we mainly make great efforts on the chip of signal input processing. Although the parameters shown can reach 1080p, they are not full HD HDCP display, and their LCD is not a point-to-point display panel composed of 1920 pixels horizontally and 1080 pixels vertically
4. LCD splicing screen adopts high-quality electronic components (IC, capacitor, inductance coil, etc.)
The quality of LCD splicing screen products has strict component selection system and perfect production line. The products of each production line are strictly roasted and tested before leaving the factory. Unlike "other machines", the purchase time of the panel is very compact when leaving the factory, and the production and assembly leave the factory at will. Because "other machines" have no products in stock, they can only be assembled, produced, processed and installed for customers when they need to be delivered. The time is generally very short. The quality of IC, capacitor and inductance coil directly affects the service life and safety of the display.
5. The LCD splicing screen has the unique technology of dniepro color and signal enhancement
for LCD, the control IC with accurate color control can make the display effect of LCD more brilliant. Its control IC can select 1 billion * colors from about 68.6 billion colors, which is more accurate in restoring the color of the object. The general display signal motherboard simply decodes the signal and displays it directly without IC processing.
6. The LCD splicing screen has a dynamic enhancement signal to ensure the dark color and dynamic drag of black and white
the design and material selection of IC chip and control circuit of display are also very important. The first-line large factory itself has a panel production line, which can design and develop the control circuit from the perspective of * as a professional. From material to workmanship, it can ensure that the large screen display can work stably for a long time, and strengthen the processing of various input signals to ensure the effectiveness of gray scale.
7. LCD splicing screen adopts advanced power DPMS
DPMS management system enables the power supply and signal board to play a * role to protect the LCD panel and reduce power consumption at the same time. In the "lamp driving circuit" of the display, the high-voltage strip 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 lamps placed in the panel. The more the number, the higher the brightness. For "other machines", all CCFL tubes in the panel are driven to light up, so that the display can work with high brightness for a long time and heat for a long time, which seriously loses the service life of the panel. The mystery of why the LCD splicing screen is called a low thermal energy panel is not on the LCD panel, but driving the motherboard to automatically light up the CCFL tubes in the panel by using the chip.
