LED backlight for touchscreens and cameras

Look in any new car today and you'll see traditional dashboard and central consoles being replaced by LCD displays and infotainment touchscreens. Soon we may have screens for front and rear passengers and with all the various camera, rear view mirrors could easily switch to an internal display. In fact some analysts believe the average car will have up to 20 cameras and 15 displays by 2030. Of course one issue with LCD displays is the need for good backlighting. That is where a proven step-up DC/DC conversion is vital.
