Optoelectronics are devices that are some combination of electrical and optical. Perhaps the simplest is the Light Emitting Diode or LED which converts electrical energy into light. A listing of some optoelectronic devices follows. | Optoelectronics are devices that are some combination of electrical and optical.

* Parallel - Parallel displays connect to a microcontroller via a parallel interface( the bitwidth varies from 8bits to 32bits ). Displays can have a much faster update rate then serial since they allow arbitrary graphs to be display. The displays are typically much cheaper then serial display starting as low as $20. | * Parallel - Parallel displays connect to a microcontroller via a parallel interface( the bitwidth varies from 8bits to 32bits ).
