Point spacing reflects pixel density from the distance between two pixels, and point spacing and pixel density are the physical properties of the display screen; Information capacity refers to the number of units of information carrying capacity displayed at once per unit area pixel density. The smaller the dot spacing, the higher the pixel density, and the more information capacity per unit area can be displayed at once, making it suitable for viewing at a closer distance. The larger the distance between points, the lower the pixel density, and the less information capacity per unit area that can be displayed at once, making it suitable for viewing at a longer distance.
LED display screen sight distance,
The position of the display screen and the distance from which people usually stand are only important factors in determining the distance between points when selecting an LED display screen. Generally, there is a formula * * * that best visibility distance=point spacing/(0.3~0.8), which is an approximate range. For example, a display screen with a dot spacing of 16mm (P16LED display screen) has a visible distance of 16-54 meters. If the distance between the stations is closer than * * *, the pixel points on the display screen can be distinguished. The sense of granularity is strong, and if the station is far 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 display screens, P10 or P12 is generally used for close proximity, and P16 or P20 is used for farther proximity;
For indoor displays, P2.5~P5 is generally acceptable, while P6, P7.62, or P10 can be used for further displays.
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 suggest that the low resolution of * * * should not be 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.
