Backlighting Automotive LCD Displays with LEDs
With the continued adoption of advanced driver assistance systems (ADAS) in cars and consumer demands for better infotainment systems, the number and size of in-cabin LCD displays are rising.
LCDs have been used for decades in TVs, computer monitors, notebook computers, and other small-screen applications like car infotainment systems. LCDs use a matrix driver system with Thin Film Transistors (TFTs) to turn individual pixels off and on, allowing light to pass through color filtering to generate the image.

The light that passes through the display pixels is generated by a backlighting system that resides within the LCD and diffuses light across the back of the panel. Traditionally, LCD backlighting was provided by Cold Cathode Fluorescent Lamps (CCFL), but in recent years has transitioned to strings of light-emitting diodes that can offer better image quality, a longer operating life, and a simpler drive circuit.
