Unit board specifications refer to the length and width dimensions of the LED display screen unit board, generally in millimeters (mm). Different LED unit board specifications will affect the size, resolution and splicing effect of the display screen.
Common unit board specifications include P2.5, P3, P4, P5, P10, P12.5, P16, etc., where the number after P represents the pixel pitch, that is, the center distance between two adjacent pixels, and the unit is also millimeters. .
Taking P4 unit board as an example, its pixel pitch is 4mm, and common unit board sizes are 256mm×128mm, etc. The pixel pitch of the P16 unit board is 16mm, and common unit board sizes are 256mm×128mm and 400mm×200mm. It should be noted that the unit board specifications of LED display screens of different brands and models may be slightly different.
In addition to unit board specifications, the technical parameters of LED display screens also include resolution, brightness, contrast, refresh rate, viewing angle, etc. Resolution refers to the number of pixels on the display screen, usually expressed in the form of the number of horizontal pixels × the number of vertical pixels.
Brightness refers to the luminous intensity of the display screen, contrast refers to the brightness difference between the brightest and darkest parts of the display screen, refresh rate refers to the number of times the display screen updates the display per second, and viewing angle refers to the angle from which it is viewed. Get the best visual effect when viewing the display screen. These technical parameters are very important for the selection and use of LED display screens.
