Abstract:
1. An integrated driver and light emitting diode (LED module comprising: a vertical light emitting diode (LED) having a top LED conducting surface and a bottom LED conducting surface, the LED comprising at least an n-type epitaxial layer and a p-type epitaxial layer; and a vertical transistor in series with the LED, the transistor and the LED having been formed separately and independently prior to being connected in series, the vertical transistor comprising at least an n-type silicon area and a p-type silicon area, the transistor having a first terminal, a second terminal, and a third terminal, the first terminal being a bottom conducting surface of the transistor, the bottom conducting surface of the transistor being electrically and mechanically bonded to the top LED conducting surface, the LED and transistor being substantially the same size, the LED being configured to emit light when a first voltage is applied to the bottom LED conducting surface, a second voltage is applied to the second terminal, and a first control voltage is applied to the third terminal.
