LED is divided by pixel density or pixel diameter.shenzhen led screen display module

　　Because the LED dot matrix module specifications used in the interior screen are relatively uniform, it is usually divided by the pixel diameter of the module:

　　43.75mm 44100 pixel/square meter

　　74.8mm 27800 pixel/square meter

　　75.0mm 17200 pixel/square meter

　　At present, common indoor LED displays are: P4, P6, P7.62, P8, P10. The pixel diameter of the indoor LED display will basically not exceed 10mm. The main reason is the visual distance and image display effect.

　　The pixel diameter and pixel spacing of the outdoor LED display currently do not have a very uniform standard. The number of pixels per square meter is about 2,500 points, 3086 points, 3906 points, 5102 points, etc. Outdoor screens are common: P10, P12, P16, P20, P25. Basically, the LED lights are dominated by straight modules. Because the outdoor screen is to overcome the effect of light, the LED light is high. At the same time, the visual distance of the LED display is related to the pixel diameter, so the outdoor LED display is basically P10 or higher.

　　3. Divided into monochrome, double base color, three base colors

　　Monochrome refers to the light emitting material of only one color of the display, mostly single red.

　　Double -base screens are generally composed of red and yellow -green luminous materials.

　　The three -base color screen is divided into full color, consisting of red, green (wavelength 570nm), and blue; and nature color, consisting of red, pure green (wavelength 525nm), and blue.
