LED DISPLAY DEVICE FOR DISPLAYING PATTERN ON ROTATABLE OBJECT BY LIGHT-SCANNING
First Claim
1. An LED display device for displaying a pattern on a rotatable object by light-scanning;
- wherein when the rotating object rotates with a high speed, the pattern will display;
the device comprising;
a display device for displaying at least one pattern;
the display device being fixed without rotation in operation;
the display screen being connected to one end of a power wire;
the display device including a display screen, a processor and a memory;
the processor serving to control displaying of patterns on the display device;
the memory serving to store patterns to be displayed and other processing programs;
a rotating printed circuit board having at least one bank of LEDs;
the rotating printed circuit board being arranged on one side of a rotating body so that the rotating printed circuit board can be viewed easily;
a control circuit board controlling electric conduction of each LED;
the control circuit board having a switch bank;
the switch bank including a plurality of switches;
the switching operation of the switch bank being controlled by the control circuit board;
each LED being connected to a conductive wire which is connected to one end of a corresponding switch; and
another end of the switch being connected to a power source for supplying power to the LED to light up; and
an image scanner connected to the control circuit board;
the image scanner including a plurality of light sensors and a photoelectric converter;
the photoelectric converter serving for converting sensed light into electric current;
the image scanner can scan through the display screen of the display device so as to sense the pattern on the screen;
then sensed light signals being converted into electric signals and then the electric signals being transferred to the control circuit board; and
wherein the rotating printed circuit board, the control circuit board and the image scanner are arranged on the rotating body so as to rotate with the rotating body.
