The small pixel pitch LED has improved the image quality significantly on the LED display screen. Moreover, it shortened the viewing distance and have resolved technical problems related to low grayscale and high brightness. Also, it is widely accepted in many industries. So, what is a small pixel pitch LED? Continue reading the article to know more about it.


What is LED pixel pitch?


If you are looking for digital signage for your brand, LED pixel pitch is the industry term that you should be accustomed to. So, when it comes to finding the right LED display, it is important to know about the pixel pitch. That way, you can understand what is right for a successful image display.


In layman's terms, pixel pitch is the overall distance between pixels. Usually measured in millimeters, a pixel pitch is a measurement from the midpoint of a pixel to the midpoint of an adjacent pixel. When the pixel pitch is small, the LEDs will be closer. And, it results in higher resolution quality.


Higher pixel pitch means more distance between pixels. As such, you get a lower resolution. A small pixel pitch LED display relates to the resolution for optimal viewing distance. When the number is small, more pixels are used to make the image on the display. As such, it improves the display resolution and optimal viewing distance.


It means, when the pixel pitch is small, a viewer can have a good resolution even when standing close to the display. While small pixel pitch LED does improve the picture quality, they come at a hefty price. In short, when you have more LED clusters on the display, the pixel pitch will be lower. And, your expenses will be higher.


However, you can cut costs without compromising on the display quality by choosing a large pixel pitch provided your audience isn't too close to the screen. However, if there isn't much space between the screen and your audience, a small pixel pitch with 4mm is a must-have.


If you want to hang the display higher and further from your audience such as airport signage, a 6mm pixel pitch LED display should be the best choice. Images from a small pixel pitch LED make the edge of the image clear and the information is restored accurately.


How to measure pixel pitch?


On a discrete LED display, a pixel represents an LED lamp that is composed of 3 sub-pixels. Each of them represents an individual LED that comprises 3 RGB components. As you know, pixel pitch is used to describe the distance between two adjacent pixels on display screens, monitors, and televisions.


When it comes to curved displays or flat panels, where the screen has either light emitting or light-reflecting technology, pixel pitch is measured on the screen's surface. With the help of projection technology, pixel pitch is measured from where it is projected instead of the destination screen.


However, most of the time it is academic for people, and during vetting for an appropriate display for a specific application, you may hear pixel pitch while describing image quality on rear projection, LED back-lit LCD, LCD, and so on. Moreover, these technologies are always described in terms of "definition" or "resolution".


For example, high-res, high-def, high-definition, 2X, 4X, etc. And, "pixel pitch" is reserved for LED display technology. When it comes to indoor or outdoor SMD-LED or discrete display technology, it is all about the vertical and horizontal distance between the centers of LED lamps that are composed of the red, green, and blue diode.


In general, when is about calculating the pixel pitch o fa LED display, you need to calculate the total pixels that the screen can have. And, it shouldn't be less than 30,000 pixels. For example, if you need a 3x1 m screen, you need to convert the size to sq. m. and multiplying the base with its height.


In this case, you should have a LED with a 3 m. sq. screen. Next comes the pixel pitch that when multiplied by the number of pixels/m2 will give the value of 30,000 pixels. So, if you multiply the surface by 10mm pixels, you can reach the recommended pixels for producing videos and images.


What is a good pixel pitch?


There is no question that LED pixel pitch is an important thing you need to consider when it comes to viewing distance. Moreover, if the person goes too close to the screen, he or she can see the small pixels including the gaps in between them. This is when the viewing experience is not a satisfied one.


But what should be the right pixel pitch so that the viewing distance becomes accurate? Appropriate viewing distance means when the visuals are clear and there isn't any gap. While many theories revolve around the appropriate measurement and ratio, most experts agree that 1mm is the best pixel pitch accompanied with 8 feet viewing distance.


These days, viewing distance is attracting lots of attention and importance. That is because it is not only about the image quality but certain things such as project planning and expenses need its help. For example, you may want a 1mm pixel pitch but if the audience is 25 feet away, it is unwise to invest in a premium product. Instead, a 3mm display can do the job well.

Pixel pitch is a technical term that people use to differentiate between LED tiles. A pixel is nothing but an individual LED. And, the pixel pitch indicates the distance between two adjacent LEDs, measured in millimeters. Also, it indicates the minimum viewing distance calculated in meters.


In general, the optimal viewing distance should be 2 to 3 times that of the pixel pitch in meters. Moreover, pixel pitch impacts optimal viewing distance and the overall visual performance of the LED display screens. Pixel pitch is crucial because it helps to optimize the viewing distance needed for the display.


Keep in mind that an image might achieve finer details with a smaller pixel pitch. That's the reason why small pixel pitches are best for LED screens. That way, your audience can stand close to the display and enjoy a clear picture without worrying about the distraction caused by individual pixels.


Therefore, when it comes to determining the best viewing distance, one of the popular choices for people is to opt for a smaller pixel pitch. Smaller pixel pitch is the best thing for a close viewing distance. Hence, a 1.2mm LED display to have a higher resolution and optimum viewing distance compared to a 16mm LED screen.

With the evolving technology, the small pixel pitch LED display is in great demand. So, whenever you are looking for one, don't go after high configuration such as high-res, big size, tiny pixel, and so on. If you are looking for the right small pixel pitch LED, here are certain factors you need to consider.


  • Overall project budget - One of the benefits of a small pixel pitch LED display is that they have no stitch and can be separated infinitely. However, with the increase of LED lamp beads on each unit area, the requirement for circuits and heat dissipation is getting costly. As such, the small pixel pitch LED screen goes higher as well. When productivity rises and technology developed, the prices might be impacted.
  • Maintenance costs - For big screen size, the overall budget isn't the only thing to consider. High maintenance is another important factor that should be considered. In general, while the average life of an LED display might be around 100,000 hours, the density of these lamps is higher. Apart from that, the indoor thickness for PCBs isn't higher compared to outdoor. As such, it will make it difficult for the heat to dissipate and might cause partial failure. Power consumption can't be ruled out either. Operational costs for big LED displays are high.
  • Setup space - The small pixel pitch Led screens means that the image quality is much sharper even when you watch them from a close range. Therefore, if you need to watch the screen from a distance, you can choose a slightly bigger pixel pitch LED. Many people calculate the view distance as View distance = pixel pitch / 0.3~0.8.
  • Transmission compatibility - If you want the small pixel pitch display to work efficiently, the transmission equipment is crucial. For example, the monitoring system for security applications uses signal transmission in the form of 1080P, 1080I, 720P, H.264, D1, etc. But small pixel screens don't support a few of them. Hence, you should know whether there is a controller to support the formats. Resolution isn't the only factor that you should worry about.
  • Fill factor - LED display comprises of dots and when you got closer, the image becomes incomplete with non-uniformity in brightness. Sometimes, even a single dot could become ten times and cause serious eye-harsh feelings. According to the experts, the fill factor should be more than 50%.
