LCD splaissimisel on järgmised omadused:
It can be used as a monitor alone, or it can be spliced into a large screen for use;
It can be realized according to different usage requirements, but the single-screen split display, the image frame can be compensated or covered;
Support digital signal roaming, zooming and stretching, multi-screen display, setting and running of various display plans, and the versatile large-screen function of real-time processing of full HD signals;
The LCD splicing screen is a complete product that can be used immediately, whether it is a single or multiple LCD splicing installation is very simple, but the large-screen display system is not that simple. The most important link is debugging! Only when the debugging is successful can it really operate. However, during the debugging process, some corresponding problems may occur, such as: unclear images in the debugging program of the video wall system; at low brightness, blurring the edges of the image, the interference fringe image with too high source resolution or stacking sense The result of frame loss is that the liquid crystal of the mosaic image does not contain a clear phenomenon and cannot be used, etc. Let me talk about the specific requirements for installing LCD splicing screens.
One, the choice of installation ground
The installation ground for LCD splicing screens should be flat, because the entire system of LCD splicing screens is relatively large in terms of volume and weight. The selected floor also needs to have a certain ability to bear weight. If the floor is tile, it may not be able to bear its weight. Another point is that the installed ground must be anti-static.
Second, the precautions for wiring
When installing the LCD splicing screen, pay attention to distinguish the power line and signal line when wiring, or mark it with a marker, and then install them in different places to avoid unnecessary interference. In addition, it is necessary to calculate the length and specifications of various lines required according to the screen size and installation location required by the project to avoid insufficient material supply or waste.
Three, ambient light requirements
LCD-ekraani heledus on palju heledam kui ühe ekraani heledus, kuid peate teadma, et helendaval korpusel on alati oma piirväärtus, nii et ümbritseva keskkonna valgus ei tohiks paigaldamisel olla liiga tugev, et valgus oleks liiga tugev, et näha vedelkristallekraani splaissimist. Ekraanipilt. Ekraani (näiteks akna) lähedusse siseneda võiv valgus tuleks vajadusel blokeerida ning seadme töötamise ajal seadme normaalse töö tagamiseks lülitada tuli välja. Ärge paigaldage valgustit otse ekraani ette, vaid paigaldage allvalgusti.
Fourth, the framework requirements
In order to facilitate the maintenance of the LCD splicing screen in the future, the frame edging must be a detachable edging. A gap of about 25mm is reserved on each side of the inner edge of the outer frame from the outer edge of the splicing wall, and the margin should be appropriately increased according to the number of columns in the large-scale splicing wall. In addition, in order to enter the cabinet for maintenance later, the maintenance channel is in principle not less than 1.2m wide. The detachable side strips should preferably be pressed by 3-5mm from the edge of the screen. After the cabinet and the screen are fully installed in place, the detachable side strips are finally fixed.
5. Ventilation requirements:
In the maintenance passage, air conditioners or air outlets must be installed to ensure that the equipment is well ventilated. The location of the air outlet should be as far away as possible from the LCD splicing wall (about 1m is better), and the air from the air outlet should not be blown directly against the cabinet to avoid damage to the screen due to uneven heating and cooling.
In the LCD splicing construction site, the installation and debugging should be based on the phenomenon reflected by the fault to determine the cause, and the synchronization interface and transmission cable of the equipment should be checked, and the synchronization frequency range of the signal source and the display terminal should be compared. If the image has ghosting, check whether the transmission cable is too long or too thin. The solution is to change the cable to test or add a signal amplifier and other equipment. If the focus is not ideal, you can adjust the display terminal. Facing the emergence of problems, we must first learn to analyze, so as to better solve the root cause of the problem. Through strong analysis, the inspection time can be shortened. These methods are some methods and techniques for debugging after installation. The installer must be proficient and good. Only professional people can do professional things.
