1. Unit board
The unit board is the main unit of the display screen, which is composed of light-emitting materials and drive circuits. The indoor screen is usually composed of unit boards.
2. Module
The module is the smallest display unit of the outdoor display screen. It is packaged in a fixed mold shell by several light-emitting diodes in a certain order through welding, glue filling and other processes to become a module.
3. Unit box
The unit box is the main unit of the display screen, which is composed of unit boards in a certain order. The outdoor screen is usually composed of the unit box.
4. Point spacing
It is the distance between two pixels of the bai, in mm. The denser the dot pitch is, the more pixels in a single du bit area are, the more delicate the displayed image is, and the more expensive the display screen is. Usually, the concept of point spacing is used for the outdoor screen, including P6, P7.62, P8, P10, P12, P16, P20, etc. I wrote an article "How to select LED display screen based on point spacing", in which the point spacing and selection are described in detail.
5. LED brightness
The brightness of LED is generally expressed in Luminous Intensity, and the unit is candela cd; 1000ucd (micro candela)=1mcd (millicandela), 1000mcd=1cd. The light intensity of a single LED for indoor use is generally 500ucd-50mcd, while the light intensity of a single LED for outdoor use is generally 100mcd-1000mcd, or even more than 1000mcd.
6. LED pixel module
LED is arranged into a matrix or pen segment, and prefabricated into a standard size module. The indoor display screen commonly uses 8 * 8 pixel module and 8-word 7-segment digital module. Outdoor display screen pixel module has 4 * 4, 8 * 8, 8 * 16 pixels and other specifications. The pixel module for outdoor display screen is also called the header module because each pixel is composed of more than two LED tube bundles.
