Since the LCD splicing is a complete product, ie, ready to use, whether it is a single or multiple LCD splicing installation is very simple, but the large-screen display system is not so simple. After installation, to the most important part ---- debugging! Only when the debugging is successful can it really work. However, during the debugging process, some corresponding problems may occur, such as: the image of the video wall system's debugging program is not clear; at the low brightness, blurring the edges of the image, the source resolution is too high for the interference fringe image to misshape the stack or The drop frame causes the liquid crystal that results in a mosaic image to contain no explicit phenomenon and cannot be used. And so on, here's how to parse the problem for everyone:
First: to check the first item to bear a certain period of time, the inspection will be deleted, once the problem is solved, you can save the inspection time in other parts.
One by one, only such peer-to-peer, can form a display resolution of the terminal monitor and the display resolution of the signal source. If this problem is not solved, it is excluded from all devices to verify the video signal: 1. Whether to rely on adaptive arrival End point; 2, the display format, the brightness of the image can be greatly improved; 3, the replacement of the display device terminal scaling You can increase the conversion device, such as the use of this change in the nature of the signal, can improve the video signal VGA video signal.
Second: Please see the body of the bandwidth matrix switcher between the image and the source impedance within the distance range to minimize the loss.
Third: The integration of key and display devices is normal, and the signal processing circuit is good.
Fourth: reliable and good line construction on the ground in order to make signal ground, solid interface cleanliness cables separate, and the strength and strictness of the power, the number of signal lines, such as UPS, AC power connectors at both ends, marking and management a simple The test.
No matter what kind of problems occur in the implementation of project installation and commissioning for customers, we need to conduct a comprehensive analysis based on specific issues. While providing customers with high-performance products, both in terms of solutions and superb technology, we must do first-class service to allow customers to use the rest assured.
Large-screen LCD splicing correct debugging method
Large screen LCD splicing correct debugging method with the LCD large screen applications widely. LCD splicing features: used alone, as a display, spliced ​​into a large screen. According to different usage requirements, single-screen split display, single-screen single display, arbitrary combination display, full-screen liquid crystal splicing, double-splicing LCD splicing screen, and vertical screen display can be realized. Image frames can be compensated or covered, and digital signals can be roamed and scaled. Extensive, multi-screen display, setting and operation of various display plans, full-HD signal real-time processing of the ever-changing large-screen features.
