Optoelectronics includes all products and procedures that permit the conversion of electronically generated data and energy into light emissions, and vice versa. This includes devices which connect optical and electrical components to one another. In so doing they act as transmitters or receivers. Whilst LEDs generate light from current, i.e. act as transmitters, photodiodes or photoresistors do the exact reverse. The combination of transmitter and receiver within a single component is referred to a an optocoupler. Optoelectronic devices are incorporated in many devices in everyday use. Amongst other things these include light bars, LED displays and TFT displays, all of which of course you can order here in the shop.
