First, physical indicators
Pixel center distance from pixel pitch The distance between the centers of adjacent pixels. (Unit: mm)
Density (points)
The number of pixels per unit area (unit: point / m2). There is a certain computational relationship between points and the same point spacing. The calculation formula is: density = (1000 ÷ pixel center distance). The higher the density of the LED display , the sharper the image and the smaller the optimal viewing distance range.

Material and the process
Most of wood cable drum are pine wood,and about the process we make the step
Raw wood→Timber→Wood cable drum. All of the wood are come from forest.
–Structure
The diameter of both side circle is about 0.8m-3.5m and we also can meet your

enough products for you.
–Price
Have our own factory and workers and machine,so the price is more cheaper
than others
