Mixing LED-LED display manufacturing procedure
This is the first article of the "LED Display Manufacturers Encyclopedia" serial. But there are many history articles belong to this serial in fact. Now we will not change the titles of them because we don't want to conflict with the brower's existing favourites. So you could browse more to find the knowledge you want to learn. And if you're in led display business, we believe each knowledge page would be worthful especially if you are one of the purchasers. We always have the objective stand when we share our knowledge, no matter if you are client of us or not. Under this directory, the articles are not for commercial or advertising.
In this LED Display Manufacturers Encyclopedia, we shall introduce one process of the led display manufacturing - the LED mixing.
If we show you some LEDs for the LED display production, you would find no visually difference of its out appearance; even we light them on, you would feel them look the same. But just like an old saying "there's no leafs exactly the same in this world", there do exist some differences of the LEDs, though the differences are very tiny. But remember the led display is a visual product which needs very accurate brightness and color, because one led display requires very huge quantity of the LEDs. Once there's any slight difference between 2 areas on the led screen panel, the visual difference would be big and the screen will look awful.
So it is certainly very important to select the LEDs with close wave length and brightness. In additon, we need take further measures to eliminate the visual difference. The LED mixing is one of it.
When the LED display manufacturers receive a bulk of LEDs, they need to mix the LEDs with a special machine to disperse all of the LEDs. And when inserting the LED to the PCB board, the manufacturers need to follow the "rules of dispersion", and for that, the engineers would design a sketch of inserting the LED in advance for the workers to follow.
In essential, the LED mixing is to disperse the LEDs with slight difference on average on the LED display panel. So watching from a viewing distance, the audience would feel no brightness and color difference. So in fact, LED displays manufacturing process need to consider a lot of the rules of human vision.
As the contrary result, if the LED mixing process not accomplished or accomplished not well, the LED display screen would seem brightness and color not accordant - some part of the LED screen are darker, some part of the LED screen are brighter. So we'd say it affects directly the visual performance of the LED display. Without dispersing the LEDs on average, even with very high quality LEDs, the manufacturers could not produce a very good quality LED display.
