  enabling automotive designers to produce striking headlight designs
  matched by exceptionally long life and performance. Automobile
  designers are increasingly incorporating LEDs in lighting because
  they can be arranged in distinctive eye-catching designs—helping
  distinguish new models from old, or high end from economy.
  There is no question that automobile LED lighting has arrived, but it has not yet reached its full
  potential. Future models will feature more LED lights, including new shapes and colors, and more
  control over the individual LEDs. Simple strings of LEDs
  will give way to matrices of LEDs that can be individually
  dimmed via computer control, enabling unlimited real-time
  pattern control and animation. The future has arrived:

  Matrix LED Dimmer Enables Accurate Color Control and Pattern Production in RGBW LEDs &mdash LT Journal

  Matrix LED Dimmer Enables Accurate Color Control and
  Pattern Production in RGBW LEDs
  Keith Szolusha RGB LEDs are used in projector, architectural, display, stage and automotive lighting
  systems that require efficient, bright output. To produce predictable colors from an
  RGB LED, each of its component LEDs (red, green and blue) requires individual,
  accurate dimming control. High end systems can use an optical feedback loop
  to allow a microcontroller to adjust the LEDs for color accuracy. Adding a white
  LED to an RGB LED to produce an RGBW LED extends the hue, saturation and
  brightness values available in the color system. Each RGBW LED requires accurate
  dimming of four component LEDs. Two RGBW LEDs require eight “channels.”
  One way to drive and dim RGBW LEDs
  is to use four separate LED drivers, one
  for each color (R, G, B and W). In such a
  system, the LED current, or PWM dimming,
  of each individual LED or string is driven
  by separate drivers and control signals.
  In this solution, though, the number
  of LED drivers increases quickly with
  the number of RGBW LEDs. Any lighting system with a significant number
  of RGBW LEDs requires a substantial
  number of drivers and synchronization
  of the control signals to those drivers. The LT3965 matrix LED dimmer enables
  such a design, as shown in Figure 1. Each …
