13 Illumination Control

The controller has built in driver functions to control different types of solid-state illumination (SSI) systems. Two types of signals go into the illumination system:

  • Enable strobes: Enable strobes are meant for turning ON/OFF of the Red, Green and Blue illumination modules independently. These signals are generated by the PWM sequences.
  • Current control signals: Current control signals meant for driving specified illumination module with specific level of current. The current levels can be specified by the user using DLPA3005 set current command. In case algorithms like LED WPC (White Point Control) and/or Dynamic Black are enabled, then the illumination current values are determined by these algorithms.

Commands are provided for current control of three types of systems:

  • General PWM based
  • DLPA3005 PMIC based

Use the Set Illumination Enable command to turn the illuminators ON or OFF.
