PURPOSE: An electronic card for a LED power source is provided to offer a digital concept electronic card by including a piezoelectricity circuit and a high brightness LED. CONSTITUTION: An FPCB(Flexible Printed Circuit Board)(100) includes a film type electronic circuit(115) and a piezoelectric circuit(110). The film type electronic circuit includes an LED(120). The piezoelectric circuit supplies power to the electronic circuit. A transparent core polymer layer(130) is formed on the FPCB and includes a light guide pattern(170) which induce the light of the LED to be emitted to a side space. A tip cover(140) is created on the transparent core resin layer. |
