As we all know, dot interval is an important index of LED electronic screen. What is dot interval? Point spacing reflects the pixel density from the interval between two pixels. Point spacing and pixel density are the physical characteristics of the display screen; information capacity is the quantity unit of information carrying capacity displayed at one time of pixel density per unit area.
How to choose the interval of LED electronic screen? To sum up, there are two main elements as follows:
First, the viewing distance of LED electronic screen
Where to put the electronic screen, usually how far apart people stand to see, is only an important factor to determine the point spacing when selecting the LED electronic screen.
Usually there is a formula, the best visual interval = point interval / (0.3 ~ 0.8), which is an approximate scale. For example, for a display screen with an interval of 16mm, the best visual interval is 20-54m. If the distance between stations is closer than the minimum distance, the pixels of the display screen can be distinguished. The sense of graininess is relatively strong. If you stand far away, the human eye can’t distinguish the features of details. We aim at normal vision, not including myopia and hyperopia. Originally, this is also an approximate figure.
For the outdoor LED electronic screen, P10 or p12 is usually used for the closer one, p16 or P20 for the farther one, while for the indoor display screen, P4 ~ P6 is usually available, and p7.62 or P10 for the farther one.
Second, the total number of pixels of LED electronic screen.
About video, the fundamental is VCD format, resolution 352 * 288, DVD format 768 * 576. So as for the video screen, we advocate that the minimum resolution should not be lower than 352 * 288, so that the display effect is good enough. If again low, can appear, but cannot achieve the very good function.
As for the display of text and image based single and double primary color LED electronic screen, the requirement of resolution is not high. According to the actual scale, the question of minimum display of 9 font can be determined according to the amount of your text.
Therefore, in the selection of LED electronic screen, if it is installed in the indoor LED electronic screen, the smaller the interval is, the better, the higher the resolution will be, and the display will be clear; if it is outdoor LED electronic screen, we should think about the viewing interval. If the interval is too small, people in the distance can’t see clearly, if the interval is too large, people in the near can’t see clearly, so we should sum up and think. However, we need to think about factors such as scale and capital.
