LED displays are no stranger to the display industry, but what is pixel spacing? What does it mean? Maybe not everyone can answer exactly. Here's what pindar engineers have to say:
What is pixel spacing?
The pixel pitch, which describes the density of pixels (LED wafers) on an LED display and is related to the resolution, is sometimes referred to as the pitch, which is the distance (in millimeters) from the center of a pixel to the center of an adjacent pixel. Since pixel spacing reflects the size of the space between two pixels, a smaller pixel spacing means less space between pixels, in other words, higher pixel density and higher screen resolution.
● pixel spacing refers to the density of pixels
● smaller pixel spacing represents higher pixel density and resolution
● pixel spacing is important because it affects the viewing distance
● the smaller the pixel spacing, the closer the viewing distance
● the viewing distance of the screen also reflects the pixel spacing value
Why is pixel spacing so important?
Pixel spacing is important because it affects the * viewing distance of the display. Lower pixel spacing allows for smoother edges and finer details. This allows the viewer to get closer to the screen and appreciate the sharp image without seeing individual pixels. When determining viewing distance and pixel spacing, the rule of thumb is that a smaller pixel spacing equals a smaller viewing distance. In contrast, larger pixel spacing increases the viewing distance. So piece one. The 2mm screen will have a higher resolution and smaller * viewing distance than the 16mm screen.
Note that although higher pixel density can improve visual quality, it does not mean that smaller pixel spacing is an ideal choice in any case. The extra pixel density is designed to provide a closer view. At larger viewing distances, the higher pixel density loses its visual advantage and increases its cost.
What kind of pixel spacing can meet my needs?
Smaller pixel spacing usually offers higher resolution, but is more expensive. Because it requires more LED wafers to create a higher pixel density, the material and production costs are higher.
So the question is, what kind of pixel spacing is appropriate? The answer is that consumers can determine the pixel spacing value of the LED screen by determining the viewing distance of the screen. The so-called viewing distance refers to the critical point of image fidelity. If the observer is too close, the image quality will decrease or the screen will appear pixelated.
For example, screens with interactive touch schemes require small pixel spacing to provide clear images to nearby viewers. LED screens that play in public, such as those that hang from the stage, can be made with higher pixel spacing. In simple terms, a smaller pixel spacing provides a higher-quality image, but if the screen is farther away from the viewer, the extra investment may not be necessary.
The industry generally USES three methods to determine the acceptable viewing distance:
Rule 10: this is a quick way to calculate approximate estimates of visual sensitivity distance.
The calculation formula is: pixel spacing ×10 = approximate viewing distance (in feet)
Visually sensitive distance: also known as retinal distance, this is the distance a person with 20/20 vision must keep from the screen in order to see a coherent image rather than a pixelated one.
The calculation formula is: pixel spacing ×3438 = visual sensitivity distance (in feet)
Average comfortable viewing distance: this is most people's estimate of comfortable viewing distance. This is a subjective estimate and will take into account such variables as eye line of sight, content resolution, and content type.
Although these methods are instructive, there is no correct answer for determining the viewing distance. The viewing distance of the screen * ultimately depends on whether the screen owner is comfortable.
