Part 1: Got Spares?
Topic: The importance of having spares when purchasing / commissioning a DVLED video wall..
My wife is very particular. When we were planning for our wedding, she suggested that me and my groomsmen wear black suits. I said…
“Great! They’ve all got a black suit already. One less thing to worry about. Right?”
My wife explained to me that black is not black. She pointed out that if you have seven men stand next to each other in seven different black suits, then the shades of black will be noticeably different. Apparently, this would be bad for our wedding photos.
The point is – she was right. As usual. The difference of one shade of black next to another is very plain to see to even the most untrained eye. She had me. I had to make the call to my groomsmen, saying, “Sorry fellas, you’ve all got to go out and get new black suits.”
LED Panels & Batching
It’s the same with LEDs and batching. One batch will not be exactly the same as another in terms of color and calibration, so when taken together on a large video wall and compared directly with another wall made up of another batch of LEDs, there will be noticeable color differences between the two.
To address this problem, dvLED manufacturers will often provide spare modules from the same batch. This way, when a pixel goes out or a module is damaged or in need of repair, the spare can be swapped in to replace the damaged unit. If you select a solid manufacturer with U.S. service centers, they will usually repair your damaged unit and send it back to you under warranty. Once you have the repaired module back, it now becomes one of your spares.
Now, let’s say you didn’t select a manufacturer that offered spares or, perhaps, offered spares but no U.S. service. What happens when you need to replace a damaged unit? Well, best case scenario, you will be forced to purchase a new module from a different batch to replace the damaged one. The problem is that this new module could very easily stick out like a sore thumb and your brand-new video wall will forever be imperfect.
Worst case scenario, the module you are replacing was from a discontinued model and cannot be replaced. Now your video wall just became a really expensive paper weight! Try explaining that to your customer…
