The constant current source receives a variable voltage input and outputs multiple constant current channels to one or more light sources for the vehicle display. The controller is further operable to alter a color or brightness of the light sources in response to a change in status of another vehicle system, thereby providing an indication to the user of the change in status."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"LED driver for vehicle display illumination","description":"A vehicle display illumination system includes a controller controlling a constant current source.
