Abstract

A display sticker with integral LED flasher circuit and power source adapted to be adhesively affixed to and readily removed from a fabric article. A printed circuit board having an LED, a control circuit and a battery is adhesively affixed to the back surface of a thin flexible sheet having printed indicia on its front surface. A rubber-based, pressure-sensitive adhesive is provided on the back surface of the flexible sheet to adhere the circuit board thereto, and also to adhere the sticker assembly to a fabric article such as an article of clothing.

Claims

1. A self-contained display sticker with an electronically controlled dynamic display, comprising:

a flexible sheet having front and back surfaces and printed indicia on said front surface;

an adhesive applied to said back surface of said flexible sheet;

a dynamic indicator; and

a printed circuit board smaller in surface area than said flexible sheet mounted on the back surface of said flexible sheet, said printed circuit board having integrally mounted thereon a signal generator IC having an output connected to said dynamic indicator, and a battery power source with a capacity less than or equal to 200 mA-hr electrically connected to said signal generator IC as the sole power source for said IC and said dynamic indicator.

2. The self-contained display sticker of claim 1, wherein said dynamic indicator is integrally mounted on said printed circuit board.

3. The self-contained display sticker of claim 2, wherein said indicator is an LED and said signal generator IC includes means for energizing said LED to flash at a humanly perceptible rate.

4. The self-contained display sticker of claim 2, wherein said printed circuit board has a single light-emitting element integrally mounted thereon as said dynamic indicator.

5. The self-contained display sticker of claim 2, further comprising a pushbutton switch integrally mounted on said printed circuit board and electrically connected to said signal generator IC.

6. The self-contained display sticker of claim 5, wherein said switch is a membrane switch.

7. The self-contained display sticker of claim 1, wherein said printed circuit board has front and back surfaces and said signal generator IC and battery are integrally mounted on said back surface of said printed circuit board, and wherein said front surface of said printed circuit board is affixed to and flush against the back surface of said flexible sheet.

8. The self-contained display sticker of claim 1, wherein said flexible sheet includes a pre-punched hole therethrough, wherein said indicator is an LED protruding through said hole when said printed circuit board is mounted on said flexible sheet, and wherein said signal generator IC includes means for energizing said LED at a rate of at most about 10 flashes per second and for a duration of less than five msec. per flash.

9. The self-contained display sticker of claim 1, wherein said signal generator IC includes a sleep state during which it draws 1 μ

A or less of current.

10. The self-contained display sticker of claim 1, wherein said printed circuit board is positioned near the center of said flexible sheet so as to be spaced apart from the periphery thereof.

11. A method of attracting attention to a display sticker bearing printed indicia on a front surface thereof and adhesive means applied to a back surface thereof for removably adhesively affixing said sticker to a mounting surface, comprising:

integrally mounting on a printed circuit board smaller in surface area than said sticker a control circuit means for energizing a dynamic indicator to operate in a humanly perceptible manner to attract attention to said printed indicia on said front surface of said display sticker, and a battery power source with a capacity less than or equal to 200 mA-hr electrically connected to said control circuit means as the sole power source for said control circuit means and said dynamic indicator; and

adhesively affixing said printed circuit board with said integrally mounted control circuit means and battery power source to said back surface of said display sticker, thereby producing a self-contained, electronically controlled, dynamic display sticker.

12. The method of claim 11, further comprising integrally mounting a pushbutton switch on said printed circuit board and electrically connecting said pushbutton switch to said control circuit means to control the energization thereof.

13. The method of claim 12, wherein said switch is a membrane switch.

14. The method of claim 13, wherein said printed circuit board has front and back surfaces and said control circuit means, battery power source, and pushbutton switch are integrally mounted on said back surface of said printed circuit board.

15. The method of claim 14, further comprising punching a hole through said sticker, providing an LED as said dynamic indicator, and mounting said printed circuit board such that said LED protrudes through said hole in said sticker.

16. The method of claim 15, further comprising energizing said LED with said control circuit means at a rate of at most about 10 flashes per second and for a duration of less than 5 msec. per flash.

17. The method of claim 16, further comprising providing said control circuit means with a sleep state during which it draws 1 μ

A or less of current.

18. The method of claim 17, wherein said printed circuit board is positioned near the center of said sticker so as to be spaced apart from the periphery thereof.
