In the past, automotive interior displays such as instrument clusters were backlit primarily by vacuum fluorescent (VF) or incandescent lamps. Then LCDs started to make inroads. For years, the LCD backlighting technology of choice (and necessity) has been cold cathode fluorescent lamps (CCFLs). CCFL-backlit LCDs, powered by DC/AC inverters, have been used to achieve the brightness, durability, operating temperature range and styling demanded by automotive applications.
Advances in LED technology and the way LEDs can be incorporated into a backlight are changing the landscape. Now, LEDs are in everything from a simple monochrome PRNDL display, to instrument clusters, to fully integrated entertainment/navigation/HVAC/Trip Comp/Messaging center console displays.
