One variety of these devices uses either active matrix or passive matrix addressing schemes; that organic variety of these devices can be used in flexible displays. The frequency of these objects' outputs is determined by the bandgap of the semiconductor that makes up a pn junction; at that junction, electrons fall into holes to release photons. For 10 points, name these diodes used in illumination.
