About Video wall, which is what we often call video wall debugging service! Now many companies have bought video walls and found that the display effect is always wrong – either the color is dark or the light, or the eyes are hurt when the seam is filled! How can this tall and powerful display truly exert its domineering effect? This service is actually a technical job specifically to solve these headaches and provides global procurement services for weak current intelligent products!
Wall calibration, simply put, adjust every small screen that makes up the large screen to be appropriate! They must be evenly bright like a whole screen, with a small color deviation that cannot be seen, and the seams must be handled so that you can hardly notice the conversion. Why is it so difficult? Because a few different screens are put together, before calibration, just like each screen has its own temper, it is disobedient
1. Brightness uniformity debugging : First use professional equipment to measure the current brightness of each screen and record the jumping data; then use calibration software to adjust it bit by bit, and finally, you have to make the brightness of each screen, even different areas of each screen… basically the brightness is no different. (General professional services can adjust uniformity to more than 95%!)
2. Color consistency correction : This step is more troublesome! It is necessary to ensure that red is the standard red, and blue must be the right blue; this screen cannot be purple or green… After proofreading, from which angle you look at it, no matter which screen you have to have the same color!
3. Geometric splicing calibration : This is like putting a puzzle with many pieces. You must make the edges of each screen aligned up, down, left, and even the curves of the chamfered corners tightly!
Some users have asked me if I can adjust it casually and just calibrate it? Oh, that's far from that
=Self-tuning: It's just a simple operation such as pulling brightness in the menu, which cannot solve the fundamental uniform problem. It seems to be almost the same…it won't take long but it won't work.
=Professional service: People bring advanced instruments to the door, can speak with scientific data, and can also give… calibration reports, etc., and some service providers also provide the half-year review of the effect! More reliable, isn't it
How long can one calibrate? Generally speaking, as long as the screen is not moved frequently, there will be no major changes in the ambient lighting. Video wall calibration services are done carefully and there will be no problem using it for one or two years to achieve stable results! However, it is recommended to check once a year for the 24-hour shopping mall advertising screen to find out subtle deviations.
What do you need to prepare? Clean the gray on the surface of the unit in advance and reserve some space for people to operate calmly… The technician will bring his own notebook and that device.
How long does it take? The case with more than a dozen screens can be handled in about an afternoon. If there are too many screens or the problem of adjusting the first time is serious… it may take a whole day to look like it! I know that a very good company provides global procurement services for weak current intelligent products! In this industry, it is easier to do things with guaranteed equipment and accessories.
It is recommended that video wall users who have not been calibrated or feel uncomfortable are contacted to try it out quickly. The effect changes are so big that it can be scary! It’s really good for whoever uses it, and it’s not unfair to spend money on it!
