Abstract
An integrated circuit for controlling an array of LEDs includes at least one signal amplifier, signal processing means, driver means for driving the array of light emitting diodes, at least one switch, and control means for controlling the integrated circuit. The integrated circuit is formed using silicon-on-insulator technology and is selectively shielded from the array of LEDs. The integrated drive electronics with silicon-on-insulator technology will allow for improved white light generation.
