As we all know, dot interval is a main goal of LED electronic screen. What is dot interval? The interval between pixels reflects the pixel density from the interval between two pixels. The interval between pixels and the pixel density are the physical characteristics of the display screen; the information capacity is the quantity unit of the information carrying capacity displayed by the pixel density per unit area at one time.
How to choose the interval of LED electronic screen? To sum up, there are two main elements as follows:
Number one, viewing distance of LED electronic screen
Where the display screen is placed, and how far apart people usually stand to see, is only one of the main factors to determine the point spacing when selecting the LED electronic screen.
Generally, there is a formula that 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 interval, the pixels of the display screen can be distinguished. The sense of particles is relatively strong. If you stand far away, the human eye can not 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 close space, p16 or P20 is used for the farther space, while for the indoor display, P4 ~ P6 is usually available, and p7.62 or P10 is used for the farther space.
Second, the total number of pixels of LED electronic screen.
The resolution of video is 768 * 352, the resolution of DVD is 768 * 352. So as for the video screen, we advocate that the minimum resolution should not be lower than 352 * 288, which is good enough. If again low, can appear, but cannot achieve the very good function.
However, for the single and double primary color LED electronic screen which mainly displays text and pictures, the resolution requirement is not high. According to the practical size, the question of minimum display of 9 font can be determined by your text size.
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.
