  • LED chip integrated with hybrid sensor and method of fabricating the same
    Patent number: 10211382
    Abstract: The present invention relates to a light emitting diode (LED) chip, in which a hybrid sensor is formed in a nitride-based LED structure. A chip structure embedded with such a hybrid sensor functions as an LED light emitting sensor which can monitor environmental pollution while functioning as a lighting element at the same time and has an effect of being used as a variety of environment pollution sensors according to the type of an electrode material.
    Type: Grant
