Analog Devices and AUO team up for local dimming technology.

Analog Devices is known for its many products in the industrial, communications, automotive, and consumer markets. AUO, on the other hand, is based in Taiwan and offers solution services that advance the frontier of innovation for display, system solutions, industrial intelligence, healthcare, and energy. The companies have teamed up to introduce the industry-first technology that enables local dimming. This significantly improves power consumption by a minimum of 50% and supports functional safety requirements.

Vehicles are now being incorporated with widescreen displays throughout the cabin as increased automation and autonomy push requirements ensure less power consumption. Meeting these demands, ADI has developed a unique approach called local dimming that drives LEDs behind the screen in the car display unit. Developed through a proprietary power process technology, the driver integrates all external switching positive channel field effect transistors (PFETs), enables high resolution and high contrast ratio for large automotive displays, provides improved diagnostics of LEDs, and reduces ghost images. The system reduces power consumption by a minimum of 50% compared to the traditional edge-lit display. ADI’s power portfolio is ASIL-B to D rated, a critical consideration for many automotive manufacturers that require functional safety features to ensure reliable operation within the vehicle.

Simon Hsu, Head of the Automotive Business Unit at AUO, said, “To help us maintain our leadership position in the market as one of the world’s top automotive display manufacturers catering to some of the largest OEMs, ADI’s local dimming automotive display drivers deliver the power efficiency consistent with the quality standard of the AUO brand. AUO AmLED displays feature power savings, excellent sunlight readability and high contrast ratio, which greatly upgrade driving safety and in-cabin entertainment experience. In response to the trend of smart mobility, AUO continues to advance display technology, and we look forward to furthering collaborations with the ADI team.”

 Patrick Morgan, Corporate Vice President of Automotive Electrification and Sustainable Energy at Analog Devices said, “The future of the automotive experience is to bring consumer features into the vehicle. Through this collaboration, our technology and leadership for high-performance automotive power enable bringing the next wave of widescreen displays into the market with significantly improved power consumption and fully functional safety capabilities.”
