IC CHIP FOR NON-CONTACT TYPE DATA CARRIER, NON-CONTACT TYPE DATA CARRIER, AND SYSTEM USING THE NON-CONTACT TYPE DATA CARRIER

摘要

PPROBLEM TO BE SOLVED: To integrally mount an organic EL light emitting device on an IC chip, and to provide adaptation to mass production and expectation for cost reduction. PSOLUTION: In the IC chip for the non-contact type data carrier, an organic EL integrally formed with the organic EL light emitting device is formed into an on-chip state on a terminal side face. A light emitting device driving circuit is built in a processing circuit of the IC chip, and the light emitting device driving circuit is composed of a light emitting device lighting signal generating circuit, a booster circuit, and a level converting circuit. The light emitting device lighting signal generating circuit generates a flashing signal, a random signal, and a fixed signal as output, and it generates an output signal only when an execution signal is sent from a control circuit in a data carrier chip.
