Product Information
The spacing of the P3.91 LED screen is actually 3.91mm/7.81mm, that is, the spacing between the horizontal lamp beads is 3.91mm, and the vertical lamp bead spacing is 7.81mm. So its pixel density can be calculated as (1000÷3.91)×(1000÷7.81)=32256dot/m². The greater the pixel density, the clearer the display effect, so the display effect of the LED screen is clear.
Features
The higher-definition screen is more suitable for close-up viewing. Therefore, the P3.91 LED screen is a screen for close viewing. It is usually suitable for a viewing distance of 4 to 20 meters, so it is more used in indoor window and shopping mall atrium. In these areas, the viewing distance is short, and the playback clarity is high, and a certain degree of transparency is also required. Overall, P3.91 is the most suitable. Viewed at close range, the area is generally not very large. Therefore, its application area is mostly within 60 square meters.
