Also include the first left cable wire and the first right tightwire, the scaling plane top margin is fixed in the first left cable end end
The pulley of left end, the first left cable wire is set in the bidirectional slide wheel；The first right tightwire extreme ends are fixed on described
Scale the pulley of plane right-hand member, first right tightwire is set in the bidirectional slide wheel, by be pulled up the first left cable wire and
First the right cable wire, you can make the scaling Planar Contraction；Or along bidirectional slide wheel, the first left cable wire is drawn to the left side,
First right tightwire draws to the right, you can make the scaling Planar Contraction；
Also include the second left cable wire and the second right tightwire, the scaling plane left end is fixed in the second left cable end end
Pulley, the second right tightwire extreme ends are fixed on the scaling plane right-hand member pulley, and the second left cable wire is installed on institute
Left chain wheel is stated, second right tightwire is installed on the right pulley, be pulled up the described second left cable wire and be pulled up described
Second right tightwire can make the scaling planar development；Or along left chain wheel and right pulley, the described second left steel is drawn to the right
Rope and make the scaling planar development by drawing the second right tightwire to the left.
7. flexible LED display according to claim 6, it is characterised in that：The first left cable wire and the second left steel
The head end of rope is connected with each other, and the head end of the first right-hand member cable wire and the second right-hand member cable wire is connected with each other；
The support is provided with motor, and the motor drives the left chain wheel and right pulley；Control the motor forward or reverse
Can control the scaling planar development or contraction.
8. flexible LED display according to claim 7, it is characterised in that：First left cable wire, the first right tightwire, institute
State the second left cable wire and the second right tightwire replaces with chain, the bidirectional slide wheel replaces with two-way sprocket wheel, the left chain wheel and the right side
Pulley replaces with sprocket wheel.
Cable wire and pulley are replaced with into sprocket wheel and chain, when being driven using motor, makes transmission more accurate, chain is being driven contracting
It is more stable when putting planar development and shrinking.
9. flexible LED display according to claim 8, it is characterised in that：Middle position articulated section described in adjacent two away from
It is identical with the equidirectional scaling of LED screen from scaling.
