Description

Technical field: [0001] The invention relates to an optocoupler device, in particular to a novel organic optocoupler device, which belongs to the field of optoelectronics. Background technique: [0002] An optocoupler is an optoelectronic device that is typically used to transmit signals while being electrically isolated. It can convert a signal into an optical signal, and then convert the optical signal into a signal that can be explored. Generally, it contains at least two functional components, that is, the functional component that can output light (input terminal functional component) and the optical signal output. Functional part for input and output as a detectable signal (output functional part). The most commonly used optocoupler is to use an electroluminescent device to convert an electrical signal into an optical signal, and then use a photosensitive device, such as a photosensitive resistor, photosensitive capacitor, photodiode or phototransistor, to convert the...
