If you are confused about how to choose an appropriate direct-view LED display, then pixel pitch can play a significant role in determining it. It is a technical unit that is used to determine the LED display tiers and to signify the image quality and resolution. It enables LED display manufacturers to distinguish themselves from the competitors.
Other than that, buyers need to consider the following details in order to come up with the right LED display
What is Pixel Pitch
The distance from the center of the LED cluster/package to the next LED package, beside, below and above it measured in millimeters (mm) is referred to as pixel pitch. These packages are usually mounted on backplates and circuit boards, which are called modules.
These modules are grouped together to create larger display surfaces that are required for LED video walls. As for the cost, the wiring, manufacturing process and tiny LED lights in the modules are the important components.
Display and Pitch Resolution
For display assembly, the footprint of video walls is connected to the pixel pitch of the display screen. This idea is particularly important when a person has to create rental led video walls with specific resolutions, like 4K presentation screen.
Viewing and Pitch Distance
There is no doubt in saying that LED pitch is important while considering viewing distance. In case a person gets close to the display screen, he/she can see tiny pixels and gaps between them. That is the time when viewing experience is not satisfactory. So, what is the appropriate viewing distance? Precisely, it is when the visuals are smooth and there are no gaps.
While there are multiple theories about an appropriate ratio and measurement, most of the experts agree that 1mm is a good pixel pitch with 8ft viewing distance. The reason why viewing distance is getting a lot of importance is that it’s not just about the picture quality but project planning and expenses also need its assistance. For instance, one would admire a 1 mm pitch but if it is used at a place where the audience is 30 feet away, then there would be no point in investing on such a premium-priced product. A 3mm LED display screen can get the job done with the similar outcomes.
Nowadays, manufacturers use any of the following 3 methodologies to determine a reasonable viewing distance:
10x Rule: It is the easiest method to estimate the Visual Acuity Distance. The calculation is done as: 10 x Pixel Pitch = Estimate Viewing Distance. The resultant is usually in feet.
Retina Distance or Visual Acuity: Referred to as a formulated method of calculation, it involves an acceptable distance to which, a 20/20 eyesight individual can go without complaining about pixelated image. The formula is: 3438 x pixel pitch (in feet).
Average Comfortable Viewing Distance: Manufacturers used to estimate a comfortable viewing distance based on their observations and research. This subjective estimation is based on content resolution, type of content and person’s eyesight.
