Pantalla LED con tamaño de píxel pequeño
Pantalla LED con paso de píxeles pequeño, también conocida como pantalla LED con paso de píxeles fino, se refiere a una pantalla LED cuyo paso de píxeles es inferior a 2,5 mm y superior a 1 mm. Los pasos de píxeles más comunes son 1,25 mm, 1,56 mm, 1,875 mm y 2,5 mm.
Debido al pequeño paso de píxeles, podemos ver la pantalla LED desde una distancia más corta y la pantalla puede tener una resolución Full HD en un tamaño pequeño.
- Las pantallas LED de paso pequeño tienen excelentes características, como alta eficiencia de visualización, bajo consumo de energía y alta vida útil técnica.

Ultimate Guide for selecting Small pixel pitch led screen

What is small pitch led screen
For a certain size led screen, with smaller pixel pitch, the bigger resolution and shorter viewing distance the screen can be. With more resolution, the screen can show more details with the same image. With shorter viewing distance, we can use the screen in more applications. Small pixel pitch led screen is the led screen whose pixel pitch is among 1mm-2.5mm. Popular pixel pitch have 1.25mm, 1.56mm, 1.875mm, and 2.5mm.
Let’s imaging if you want to install a HD led screen in your company’s conference room.
If using pixel pitch 6mm, The screen size would be 11.52m W x 6.48m H, Which is not realistic
While if using pixel pitch 1.875mm, the screen size would be narrow down to 3.6m W x 2.025m H, similar to the projector’s area. But way much better viewing experience.
Quick takeouts:
1: Pixel pitch is the physical distance between adjoint pixels.(normally measured by millimeters)
2: The shortest viewing distance ( where your naked eye can not distinguish individual pixels) normally can be calculated by viewing distance = pixel pitch * 1000/0.8. You can also determine your ideal pixel pitch when you know your shortest viewing distance.
For example: For 2.5mm pixel pitch, the viewing distance is suggested to be 2.5*1000/0.8=3125mm, which means the viewing distance should be 3.125m away.
For 1.875mm pixel pitch, the viewing distance is suggested to be 1.875*1000/0.8=2343mm, which means the viewing distance should be 2.3m away.
For 1.56mm pixel pitch, the viewing distance is suggested to be 1.56*1000/0.8=1950mm, which means the viewing distance should be 1.95m away.
For 1.25mm pixel pitch, the viewing distance is suggested to be 1.25*1000/0.8=1562.5mm, which means the viewing distance should be 1.56m away.
Types of small pitch led screen
As the small pixel pitch led screen’s pixel pitch is less than 2.5mm, from the installation and application, it can be divided into two categories.
Rigid led screen with Cabinet and Flexible led screen.
Rigid small pixel pitch led screen normally has a Die casting cabinet and the LED module is attached to the cabinet by the magnet. It is very popular to make a big flat screen, and widely used in conference room, schools, hotels, and resorts, etc.
Small pixel pitch flexible led screen is normally used in applications that needs to make a curve shape. We need to customize the cabinet from project to project. Small pixel pitch flexible led screen is very popular used in Sphere ball led display, column led display and TV studio background video wall.
Different technology of small pixel pitch led screen
When the pixel pitch gets smaller, it required that the package of the led lamp should also get small. While the package of the led lamp can not become small all the way down, and when the package becomes smaller, the Electrodes on the package would also become smaller which makes the soldering on the PCB board become weak. There are four technology used in small pitch led screen led lamps. SMD, GOB, COB, and 4in one lamp.
SMD: This is the original led lamp used in small pixel pitch led screen, popular led lamp has SMD1010 for making pixel pitch 1.25mm, SMD1212 for making Pixel pitch 1.56, SMD1515 for making pixel pitch 1.875mm and SMD 2020 for making pixel pitch 2.5mm. The benefit is that there have many supplier, and also price is cheap. While as mentioned above, as the package become smaller, the electrodes also become smaller, which would make the soldering contact on the PCB not strong enough (especially under moisture), and would cause dead pixels.
GOB: GOB is a technology used to upgrade SMD. GOB means glue on board which means put a layer of glue on the SMD led board. As the glue is fixed, hence it can protect the led lamp from scratch, and also protect the lamp from moisture which means the led module have less dead pixels rate. It can also enlarge the viewing angle of the led screen.
The drawback is that even with the same batch glue, it is still possible that those glue would have color difference, which reflect on the led module.
COB: COB means chip on board, which means putting the led chip directly on the pcb board. In doing so, the led lamp does not need package anymore. The height of the led module also become smaller. It can also making even smaller pixel pitch.
The drawback are. First: it need a big investment in COB machine, Second: If there is a dead pixel, you can not repair it by changing a lamp, you would need to send it back to the factory. Third: Even produce in the same batch, the led module’s surface might have color difference. Fourth: The price is also very expensive.
4 in one lamp: 4in one lamp means 1 package consists 4 led lamps(pixels). As some of the electrodes can be used together, hence using 4 pixels in 1 package can save the electrodes and the size of the package can also become bigger which would be good for SMT process and soldering.
The drawback: The pixel pitch is determined by the 4 in one lamp, As there have four pixels in one package, hence the pixel pitch of the led screen is already determined by the adjoint pixels. This makes it tough to make different pixel pitch screen products. The price is also expensive.
Benefit of small pitch led screen
1:High contrast rate
For all led lamp used in small pixel pitch led screen are all black cover lamps, which would makes the surface of the led screen has a darker background. Besides when the pixel pitch become smaller, the gap among the led lamp also become smaller, which also enhance the dark background. The dark background ensure the led screen can have a high contrast rate.
2:High refresh rate
To power a small pixel pitch led screen, it needs high end IC, which makes the led screen has a high refresh rate, normally the refresh rate of the led screen can reach 3840Hz.
3:Shorter viewing distance
When the pixel pitch gets smaller, the viewing distance can also get smaller, Which gives us a good viewing experience.
4:Smaller sizes
For a certain resolution required led screen, small pixel pitch led screen can have a smaller size then normal pixel pitch led screen.
5:Easy maintenance
Most small pixel pitch led screens is using the magnet to attach the led module on the screen frame. Hence it is very easy to use a front service tool to replace the failure led module. Makes it very easy to maintain.
How to install Small pixel pitch LED Display
First step: Install the supporting frame of the led screen
Second step: Install the cabinet frame on the supporting frame, make the frame’s surface even
Third step: Connecting the power cable, and signal cable
Fourth step: Attach the LED module to the cabinet
Fifth step: Config the led screen, then ok to use the led screen now.
