Correct debugging method of large screen LCD splicing

Liquid crystal splicing can be used as a monitor alone, and can be spliced into a large screen.According to the different using requirements, realization of variable will be small changed larger function: single partition display, single separate display, any combination, full screen, LCD splicing, double stitching LCD splicing screen, vertical screen display, image border optional compensation or cover, support for digital signal of roaming, scaling stretching, across the screen display, all kinds of display program up and running, full hd signal real-time processing.LCD splicing is a complete product, which is ready for use immediately, and the installation is as simple as building blocks. The use and installation of single or multiple LCD splicing are very simple.The edge of the liquid crystal splice is only 9mm wide, and the surface has a protective layer of tempered glass, built-in intelligent temperature control and alarm circuit and a unique "fast dispersion" heat dissipation system.Everything, not only suitable for digital signal input, analog signal support is also very unique.LCD splicing series products adopt unique and the world's most cutting-edge digital processing technology, allowing users to truly experience the full hd screen effect.

 

So is such a perfect big-screen display really that simple?The answer is no. It is not as easy as people think to correctly adjust the LCD splice screen.

 

Under normal circumstances, the hardware installation of the liquid crystal splicing system will not take much time and is relatively simple, which is more complicated than debugging.Video wall system debugging program, the image is not clear.If the display is unsatisfactory, especially in low brightness, blurry image edges, (source resolution is too high) interference fringe image aliasing stack feeling (or missing frame), the result is: Mosaic image of the liquid crystal does not contain a clear phenomenon.Immediately determine if the product is not available.Image to control products such as systems, matrix switchers, distributors, signal transmission cables, transmission, processing and display etc. Display terminals, DVDS, cameras, computers, etc., etc.Video source displayed.

 

There are two points to note about exclusion:

 

First: to check the first item to bear a certain time cycle of the problem, to carry out the inspection, will be deleted, once the problem is solved, you can save the inspection time in other parts can.First of all, one by one, only in this way, to form a terminal display resolution and signal display resolution, not only for points, with points, if you don't solve this problem, was left out on all equipment to verify it video signal, and whether if it is to rely on to adapt to reach the destination, or display format, may be it will greatly improve the brightness of the image, or replace the equipment display terminal zoom you can increase the conversion device, such as by using the properties of the change of the signal, can improve the VGA video signal of the video signal.

 

Two, please see the institution to minimize the loss to the minimum standard??The bandwidth matrix switcher between the image in the range and the signal source impedance.Finally, the fusion of focus and display devices is normal and the signal processing circuit is good.The most important is as follows.High ground reliable, good line construction so that signal ground, solid interface clean cable separation, and power and strict as power supply, signal line such as UPS, ac power connector end total, mark and manage a simple test.

 

Analysis: according to the symptoms, such as asynchronous, synchronous interface cable and transmission equipment, control and display terminal synchronous signal source within the frequency range of examination focus.By analyzing the test for too long, too small pictures, ghosts, transmission cables to confirm whether it is a solution to add signal amplifiers to such devices, or lane changes.Centralized bad, you can adjust the display terminal.
