1、 What is LCD splicing screen
LCD splicing screen can not only be used as a display, but also be spliced into a large screen. According to different use requirements, it can realize the functions of changing the size of the screen: single screen split display, single screen separate display, arbitrary combination display, full screen LCD splicing, double splicing LCD splicing, vertical screen display, optional compensation or coverage of image boundary, support digital signal roaming, zooming and stretching, cross screen display, setting and operation of various display schemes And real-time processing of all signals.
2、 Installation method of LCD splicing screen
1. The choice of LCD splicing screen installation site
The mounting surface of LCD splicing screen should be flat, because the volume and weight of the whole LCD splicing screen are relatively large. The choice of surface also needs to have a certain bearing capacity, if the wall is tile, it may not be able to bear the weight. Another thing is that the mounting surface should be able to prevent static electricity.
2. Matters needing attention in connection of LCD splicing screen
When installing LCD splicing screen, attention should be paid to distinguish power line and signal line in wiring, and install them in different places to avoid interference. In addition, the length and specifications of the required lines 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.
3.Ambient light requirements of LCD panel
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, the screen may not be visible. The light that may be emitted near the screen, such as windows, needs to be covered when necessary. The light should be turned off when the equipment is running to ensure the normal operation of the equipment. Do not install tube lights in front of the screen.
4.Frame requirements of LCD splicing screen
In order to maintain the LCD splicing screen more conveniently, the packaging edge of the frame must be detachable. A gap of about 25 mm shall be reserved along each side of the outer frame from the outside of the partition wall, and the edge of the large screen wall shall be increased according to the number of columns. In addition, in order to enter the maintenance box in the later stage, the maintenance channel shall not be less than 1.2m wide in principle. The detachable edge strip is suitable for 3-5mm pressing edge. After the box and screen are installed, the detachable edge strip is finally fixed.
5.Ventilation requirements of LCD panel
In the maintenance channel, air conditioning or air outlet must be installed to ensure good ventilation of the equipment. The air outlet should be as far away from the LCD splicing wall as possible (about 1m), and the air at the outlet should not be directly blown to the box, so as to avoid damaging the screen and uneven heat and cold.
This paper introduces the installation method and steps of LCD splicing screen. In the LCD splicing construction site, we should judge the cause according to the phenomenon reflected by the fault, check the synchronization interface and transmission cable of the equipment, and the synchronization frequency range between the signal source and the display terminal. If the image has double shadows, 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, you can adjust the display terminal. In the face of problems, we must first learn to analyze, in order to better solve the root cause of the problem, through powerful analysis, can shorten the inspection time.
3、 Wiring method of LCD splicing screen
First: link to LCD splice box
First of all, the connection of LCD is the connection of hardware. People who know more about LCD splicing screen know that splicing screen is composed of multiple small screens, and there are many signal interfaces behind the splicing screen. For example, HDMI, DVI, VGA, RGB, components, terminals and computers are all connected to the VGA interface. Usually we just need to connect the computer to the VGA interface. Because under normal circumstances, LCD splicing screen single use less. Therefore, if the whole LCD splicing screen is connected, the line only needs to be connected to the splicing processing device. After the splicing processors are connected in series, they only need to send a signal to access.
Second: links to matrices or controllers
In the scheme of large screen splicing curtain wall, the input signal or output signal may be different, or the display of multi-channel signal input or output is required. At this time, the matrix must be equipped, and the matrix interface is more and more abundant, just find the corresponding interface. If you do not understand the matrix signal access, it is recommended to ask professional and skilled personnel for installation.
