As Fig. 3, Fig. 5 .1, Fig. 5 .2, each LED lattice module is by being made up of plate shell 111, circuit board 112, LED lamp or the chip 113 of reflection hole, its plate shell 111 be shaped as a kind of contour body, circuit board be shaped as a kind of surface plate.

Principle of work of the present utility model is:

As Fig. 6 .1, the xsect of compass LED display screen 100, its outer wall are circular, and inwall is a regular polygon, and a corresponding polygonal limit connects an arc LED lattice module cell board 110.

Because the bottom surface of arc LED lattice module cell board 110 is the plane, has guaranteed its production technology and reliability.

Because the outside surface of each arc surface LED lattice module is a cambered surface, has guaranteed that the outside surface of arc LED lattice module cell board 110 is an arc.

Because the shape of each arc LED lattice module cell board 110 is identical, be convenient to install and displacement.

The utlity model has following advantage and good effect:

1, owing to designed arc LED lattice module cell board 110, make the successful release of LED circular arc display screen become possibility;

2, simple in structure, produce, install, replace easily.

3 compare with the circular arc display screen of incandescent lamp or fluorescent light, and the utility model is a kind of convertible image, abundant in content, energy-saving LED circular arc display screen;

4 compare with the rotating LED display screen, and the utility model is the fabulous LED circular arc display screen of a kind of display effect.

5 compare with the LED display of doing the distortion of little radian, and the utility model is a kind of good reliability, installs to be easy to LED circular arc display screen.

In a word, because the utility model ratio of performance to price height can be widely used in the circular arc display screen.
