LCD splicing screen is one of the most popular display screens currently favored by users. The LCD splicing wall composed of splicing screens will encounter unclear image display in actual operation, while the large-screen image of LCD splicing wall is not clear. : low brightness, poor edge focusing, ghosting (image smearing), interference fringe stacking (signal source resolution is too high) or image jagged (drop frame), LCD splicing wall no screen display (no signal screen display) ) and so on. Then, when the above phenomenon occurs, how should the maintenance personnel debug the LCD splicing wall?

The splicing screen wall shows the blue bottom:

  First of all, you need to understand why the splicing screen shows the blue background because of the cockroaches Regardless of the entire splicing screen wall or the single splicing screen unit showing the blue background, it means no signal. Therefore, when a single screen displays a blue background, it may be that the software settings, signal processor to screen signal line interface is loose or the wire is defective, check the interface for looseness, or change the line test. When the entire splicing wall is blue or multiple screens display the blue bottom, the problem is most likely the problem of the signal processor and the signal output device, and the second may be the poor connection of the signal line and the interface. In this case, you need to check the software settings, signal processor, signal output device, signal interface, signal line until you find the problem.

Splicing screen wall black screen:

  The black screen of the LCD splicing screen may be caused by the following problems: the setting parameters of the splicing software are incorrect, the driving board of the splicing screen is broken, the LCD screen is damaged, and the power board is damaged. We check according to these 4 points, the black screen of the splicing screen may be unpowered, or the splicing screen may be closed by software or remote control to eliminate whether it is hardware damage.

Debugging LCD video wall image display is not clear:

  Firstly, the segmentation check can be performed on the LCD splicing wall to find out the problem. First, check whether the resolution of the LCD splicing wall signal source is consistent with the resolution of the display terminal. If it is a video signal, it depends on whether the system can In accordance with the display terminal, if the requirements of the display terminal are not met, the nature of the signal can be changed by swapping the device or adding a conversion device.

  Secondly, looking at the bandwidth of the splitter and matrix switcher and its impedance to the signal source, whether the loss of the image can be minimized within the range of the standard distance. Finally, see if the focus and convergence of the display device is normal, and whether the signal processing circuit is good.

  In addition, if the LCD splicing screen image is ghosted, you need to check whether the transmission cable is too long or too thin. The solution is to change the line or add a signal amplifier and other equipment. If the focus is not good, you can adjust the display terminal and so on.
