Unveiling the Most Effective Pixel Pitch for Your LED Display Screen: A Scientific Approach
The selection of LED display screen point spacing is related to two factors:
Firstly, LED display screen line of sight
The placement of the display screen and the distance from which people stand are important factors in determining the distance between points when selecting an LED display screen.
There is generally a formula for the optimal visible distance=point spacing/(0.3-0.8), which is an approximate range. For example, for a display screen with a point spacing of 16mm, the optimal visual distance is 20-54 meters. If the distance between the stations is closer than the minimum distance, the pixels on the display screen can be distinguished. The granularity is relatively strong, and if the station is further away, the human eye cannot distinguish the detailed features. We target normal vision, excluding nearsightedness and hyperopia. Actually, this is also a rough number.
For outdoor LED displays, P10 or P12 is generally used for closer distances, P16 or P20 is used for farther distances, while for indoor displays, P4 to P6 are generally acceptable, and P7.62 or P10 is used for farther distances.
Secondly, the total number of pixels on the LED display screen
For videos, the basic format is VCD, with a resolution of 352 * 288 and a DVD format of 768 * 576. So for video screens, we recommend a minimum resolution of no less than 352 * 288, so that the display effect is good enough. If it is even lower, it can be displayed, but it cannot achieve better results.
For single and dual primary color LED display screens that mainly display text and images, the resolution requirement is not high. Based on the actual size, the minimum display size of 9-point font can be determined according to your text volume.
So, LED display screens are generally chosen, and the smaller the dot spacing, the better, the higher the resolution, and the clearer the display. However, it is also necessary to consider factors such as cost, demand, and application scope comprehensively.
