1. Introduction
LED displays are not unfamiliar to those who are concerned about the display industry, but what is pixel pitch? What is its significance? Maybe not everyone can answer accurately. In this article, we will discuss the pixel pitch of LED displays.
2. What is Pixel Pitch?
Pixel pitch describes the density of pixels on an LED display and is related to resolution. It is sometimes called dot pitch, which refers to the distance (in millimeters) from the center of a pixel to the center of an adjacent pixel. Since the pixel pitch reflects the size of the space between two pixels, a smaller pixel pitch means less space between pixels. In other words, it means higher pixel density and higher screen definition.
Key Points:
1. Pixel pitch refers to the density of pixels.
2. Smaller pixel pitch means higher pixel density and higher resolution.
3. Pixel pitch is important because it affects viewing distance.
4. The smaller the pixel pitch, the closer the viewing distance.
5. The optimal viewing distance of the screen also reflects the pixel spacing value.
3. Why is pixel pitch so important?
Pixel pitch is very important because it affects the best viewing distance of the LED display. Lower pixel pitch values allow smoother edges and finer detail in the image. This allows the viewer to get closer to the screen and enjoy a clear image without seeing individual pixels. When determining the viewing distance and pixel pitch, the rule of thumb means that a smaller pixel pitch equals a smaller viewing distance. Conversely, a larger pixel pitch also increases the minimum viewing distance. Therefore, a 1.2mm screen will have a higher resolution and a smaller viewing distance than a 16mm screen.
4. What kind of pixel pitch can meet my needs?
Smaller pixel pitch usually provides higher resolution, but is more expensive. Because more LED chips are required to create higher pixel density, material and production costs are higher.
So the question is, what pixel pitch is the most appropriate? The answer is that consumers can determine the best pixel pitch value for LED screens by determining the best viewing distance of the screen. The so-called best viewing distance refers to the critical point of image fidelity. If the viewer is too close, the image quality will be reduced or the screen will appear pixelated.
The industry typically uses three methods to determine acceptable viewing distances
Choosing the right viewing distance is the key to ensuring the display effect of the LED display. Through methods such as dot pitch, resolution and screen size, as well as image quality, the appropriate viewing distance can be effectively determined to meet the needs of different applications. The following three methods are provided for your reference.
4.1 Point spacing method
Dot pitch refers to the distance between two adjacent pixels, expressed in millimeters (mm). Usually, viewing distance is directly related to dot pitch, and common empirical formulas are:
View distance (meters) = point spacing (mm)
For example, if the dot pitch of an LED display is 4 millimeters, the acceptable viewing distance is 4 meters.
4.2 Method of resolution and screen size
The viewing distance is determined by the resolution and size of the screen. The higher the resolution, the denser the pixels, and the viewing distance can be relatively close. Here is a common rule of thumb:
View distance (meters) = screen height (meters) × 2
This method is mainly suitable for large-screen displays, such as stadiums or outdoor advertising screens.
4.3 Image quality method
Considering the resolution ability of the human eye, the appropriate viewing distance can be determined by measuring whether the display content can be clearly seen when the viewer is at a certain distance from the screen. A commonly used criterion is:
View distance (meters) = 0.5 × diagonal screen (inches)
For example, a 50-inch screen has a viewing distance of about 25 meters.
Although these methods are instructive, there is no correct answer when it comes to determining viewing distance. The viewing distance of the screen ultimately depends on whether the owner of the screen is comfortable.
