| Title: |
Organic Light Emitting Diode Methods and Apparatus |
| Abstract: |
Organic light emitting diode (OLED) methods and apparatus in which at
least one first OLED generates first radiation having a first spectrum,
and at least one second OLED generates second radiation having a second
spectrum different from the first spectrum. In one example, an
addressable controller is coupled to the first OLED and the second OLED
for independently controlling a first intensity of the first radiation
and a second intensity of the second radiation based on a network signal
including lighting information for a plurality of light-generating
apparatus. An OLED controller may be in communication with a user
interface to control different OLED-generated spectrums in response to
user operation of the user interface. In one aspect, a controller may be
configured to implement a pulse width modulation (PWM) technique to
control the OLEDs.
