It closes driving element and uses commercially available matured product, the prior art is also belonged to for control circuit itself and control principle, no longer in detail
Explanation.
As shown in Figures 2 and 3, PCB printed board 1 is square, and being one-piece on its four sides has with a thickness of 3-8mm
Boss 9, and formed on each side there are two boss 9, each boss 9 at the end angle of PCB printed board 1, wherein
The distance of another side of outer side edges distance PCB printed board 1 of boss 9 is 5-15mm, generally 10mm, as shown in figure 4,8 convex
Platform 9 is on full symmetric four sides for being distributed in PCB printed board 1.
Below the LED screen module in the utility model is installed to be formed for large spherical surface LED screen and be illustrated, when
It is so not limited to this, can be adapted for the LED display of arbitrary surface, in mounting and adjusting, execute according to the following steps:
First: the LED screen module in the utility model is fixed on curved surface skeleton 8, and curved surface skeleton 8 is by stainless steel
