The majority of TFT LCD’s now have LED backlights rather than the original CCFL tubes. We also find that many displays are now supplied with integrated LED backlight drivers which allow for easier integration.

LED Backlight Drivers (medium)However, certain markets require more control and for that reason certain hi-rel displays are still supplied where a separate LED backlight driver is needed. Also, where displays have a modified backlight (perhaps High bright or NVIS) the original converter cannot be used.

To support these applications we have developed our own range of Smart LED Converters to provide the best control over modern LED backlights, and allow the customer to configure the backlight converter to their exact needs.

The Smart LED Backlight Drivers:

  • Configurable (using Smart LED Rover software) to a range of TFT displays
  • Usable as a temperature monitor and brightness control
  • Have a wide temperature range of -30 to + 80°C
  • Dimming: Smart LED-II = 10,000:1, Smart LED-III = 6000:1, Smart LED-IV = 15,000:1
  • Operating Temperature of -30 to + 80°C
  • Communicates with the converter via UART
