Welcome back to your new date with me: Blu, the one and only Boss of Wave&Co (in disguise).
After a long and intense spying/monitoring session in my Company, carefully hidden behind an innocent nap (even though, as you know, I’m always on watch!) …
I felt like telling you, dear human beings, something more about my beloved led walls.
What is an SMD LED, a DIP, and a Mini-led?
This has nothing to do with code names of doggy sneaks or mini sneaks, it’s a led technology we are talking about! If you don’t know anything about it, then it’s time for the generous me to share my knowledge with you.
DIP (=dual in line package)
These LEDs have a cylindrical shape, with a roundish upper end to improve the light dispersion. Inside it, there’s only one cell with a semiconductor crystal that emits light when crossed by electricity. Since it has only one cell it can produce just one colour (red, green or blue). That’s why we need three DIP LEDs, of different colours, to have a pixel. Depending on the led wall resolution and the distance of the screen, these LEDs will be weld closer or farther.
The key points of this kind of led are high brightness, durability, and resistance to collisions. That’s why they can be used, above all, in outdoor installations, advertising, stadiums, events, etc. and wherever the public can see them from a big distance.
SMD LED (=surface mount device)
These LEDs have a rectangular shape and three cells with a different coloured diode each. Three colours (RGB) in the same box, weld on a printed circuit. Their code name has 4 numbers: two stands for its length and the other two for its height (measures are in a tenth of a millimetre). An SMD LED 2020, will be 2mm x 2mm, just to say. Well now, if you understood me so far, you can easily imagine that an SMD LED pixel pitch is thinner than a DIP LED one, while its resolution is higher. These LEDs are mostly used in indoor installations, and to be watched from a close distance, but thanks to few technical changes (to be waterproof and brighter for example), they can be used also in outdoor installations.
For example, White Face SMD LEDs are brighter and perfect for outdoor installations, while Black Face SMD LEDs are a good choice for TV broadcast thanks to their high contrast and low reflection.
What’s SMD LEDs’ strength? High resolution, high definition, closer point of observation, even though, generally speaking, they are not as bright as DIP LEDs.
Mini-led and Micro-led
(=you don’t need me to explain this title, do you?)
We are now looking at what people may address as the future of led walls. The thinnest pitches.
A Mini-led is a light-emitting diode with a size of about 100 micrometres. Now, do you really need me to tell you what’s the resolution of a mini-LEDs screen? Ok, I will anyway: it’s surprisingly high!
On the other hand, a micro-led is smaller than 100 micrometres (!) but, alas, the current technology is not mature yet for mass production and its costs. Mini-LEDs instead are relatively cheaper because machinery is already ready to go and they can be used also to produce an LCD, not only led walls. That’s why they lead the market.
