We are choosing LED outdoor large screens by what data to judge the quality of its products? Choosing the 'dot pitch, pixel' of the large outdoor LED screen is the key data! Below, we will introduce these two data.
First, the viewing distance of the LED display screen,
Where is the display screen placed, and how far people stand to look at it, is only an important factor in determining the dot pitch when choosing an LED display screen. Generally, there is a formula for the best viewing distanceu003ddot pitch/(0.3~0.8), which is an approximate range. For example, a display with a pixel pitch of 16mm (P16LED display), the visible distance is 16~54 meters, and the distance between the stations is closer than the minimum distance, and the pixels of the display can be distinguished, with a grainy feeling. Stronger, if you stand far away, the human eye can't distinguish the features of the details. (We aim at normal vision, excluding myopia and hyperopia). In fact, this is also a rough figure.
For outdoor LED displays, P10 or P12 are generally used for the short distance, and P16 or P20 for the farther ones; for indoor displays, generally P2.5~P5 are available, and for the farther ones, P6 and P7 are used. 62 or P10.
Second, the total number of pixels of the LED display.
For video, the basic format is VCD with a resolution of 352*288, and the format of DVD is 768*576. Therefore, for the video screen, we recommend that the lowest resolution is not less than 352*288, so that the display effect is good enough. If it is lower, it can be displayed, but it will not achieve better results.
For single and dual primary color LED displays that mainly display text and pictures, the resolution requirements are not high. According to the actual size, the problem of displaying the 9th font at the smallest size can be based on your text volume. To decide.
Therefore, generally choose LED display, the smaller the dot pitch, the better, the higher the resolution will be, and the display will be clearer. However, factors such as cost, demand, and scope of application must also be considered comprehensively.
