Features of Installation Skills and Procedures of LCD Splicing Screen
The installation of LCD splicing screen
is not like ordinary display equipment, but simply installed as soon as it is placed. The installation of LCD splicing screen
should not only carefully select the installation site, but also pay attention to the light around the installation environment, and also pay attention to wiring, and there are also some requirements for the frame. Choose us to talk about how to install LCD splicing screen.
Selection of installation ground:
The installation ground of LCD splicing screen should be flat, because the whole system of LCD splicing screen is relatively large in volume and weight. The selected ground also needs to be able to withstand a certain amount of weight. If the floor is tile, it may not be able to withstand its weight. Another point is that the ground installed should be able to prevent static electricity.
Cautions for wiring:
When installing LCD splicing screen, attention should be paid to distinguishing its power and signal lines when wiring, and installing them in different places to avoid interference. In addition, according to the screen size and installation location of the whole project, the length and specifications of various lines needed are calculated, and the needs of the whole project are calculated.
Environmental light requirements:
Although the brightness of LCD splicing screen is very high, it is still limited after all, so the light around the installation environment can not be too strong. If it's too strong, you may not see the screen. The light that may be emitted near the screen (such as windows) should be shielded if necessary, 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, just install the tubular lamp.
In order to facilitate the maintenance of LCD splicing screen in the future, frame edge wrapping must be removable edge wrapping. About 25 mm clearance should be reserved on each side of the outer frame along the distance from the splitting wall, and the allowance of large splitting wall should be increased appropriately according to the number of columns. In addition, in order to enter the box maintenance later, the maintenance channel should not be less than 1.2m wide in principle. The removable edge bar is suitable for pressing the edge of the screen for 3-5mm. After the box and screen are fully installed, the removable edge bar is finally fixed.
In the maintenance channel, air conditioning or air outlet must be installed to ensure good ventilation of the equipment. The outlet position should be as far away as possible from the LCD splicing wall (about 1 m is better), and the outlet air can not be directly blown against the box, in order to avoid the screen damage caused by uneven heat and cold.
In the LCD splicing construction site, the installation and debugging should judge the cause according to the phenomenon reflected by the fault, and focus on checking 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 is duplicated, check whether the transmission cable is too long or too thin, the solution is to change the line test, or add signal amplifier and other equipment. If the focus is not ideal, the display terminal can be adjusted. Faced with 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 of debugging after installation. Installers must be skilled and good, so only professional personnel can do professional things.
