When choosing an LED full color display, it is crucial to determine the appropriate dot pitch based on the viewing distance, which will directly affect the display effect and viewing experience.
First, you need to understand the concept of dot pitch. Dot pitch refers to the distance between the centers of two adjacent pixels on the display, usually expressed in millimeters (mm). The smaller the dot pitch, the higher the resolution of the display and the clearer and more delicate the image.
For closer viewing distances, such as in indoor conference rooms, exhibition halls and other places, the audience is closer to the display, and a smaller dot pitch is usually required. Generally speaking, if the viewing distance is within 2 meters, it is more appropriate to choose a dot pitch between 1.2mm and 2mm. This can ensure the clarity and detail of the image without obvious graininess.
When the viewing distance is between 2 meters and 5 meters, you can consider choosing a dot pitch of about 2mm to 3mm. Within this distance range, it can not only ensure good image quality, but also achieve a balance between cost and display effect.
For longer viewing distances, such as large outdoor billboards, stadiums and other scenes, since the audience is far away from the display, a larger dot pitch can be selected. If the viewing distance is 5 to 10 meters or even farther, a dot pitch of 3mm to 6mm or larger may be able to meet the needs. A larger dot pitch can still present a clear image when viewed from a long distance, while also reducing costs.
For example, in a small indoor studio, the distance between the audience and the display is mostly around 3 meters. A LED full color display with a dot pitch of 1.5mm is selected, and the picture is very clear and colorful, giving the audience an excellent visual experience.
In a large outdoor square, the audience may be more than 10 meters away from the display. A display with a dot pitch of 5mm is selected, which can not only clearly display information, but also is more reasonable in cost control.
In addition, the use scenario and display content of the display need to be considered. If you need to display high-definition video, images or small text information, you may need to choose a display with a smaller dot pitch to ensure the display effect even if the viewing distance is far.
In short, determining the dot pitch of LED full color display according to viewing distance requires comprehensive consideration of multiple factors. Through reasonable selection, it can not only meet the requirements of display effect, but also optimize costs and bring satisfactory visual effects to the audience.
