Analog Devices (ADI) and AUO are collaborating to launch a safe and power-efficient widescreen display for automotive applications.


ADI announced on the 3rd that its Matrix LED display driver technology will be used in AUO's automotive widescreen display portfolio.

This technology enables local dimming, significantly improving power consumption by at least 50% and supporting functional safety requirements.

ADI developed a unique technique called 'local dimming' that drives LEDs behind the screen of automotive display devices.

Developed through proprietary power processing technology, this driver integrates all external switching positive channel field-effect transistors (PFETs), enabling high resolution and high contrast ratio for large automotive displays, providing enhanced LED diagnostic capabilities, and eliminating ghost images.

This system reduces power consumption by at least 50% compared to existing edge-light displays.

ADI's power product family consists of ASIL-B to D grades, which is an important consideration for many automotive manufacturers requiring functional safety characteristics to ensure stable operation within vehicles.

ADI aims to enhance the vehicle interior experience by implementing not only high-resolution displays through GMSL (Gigabit Multimedia Serial Link™) serializer and deserializer (SerDes) connectivity solutions, but also energy-efficient widescreens capable of local dimming through proprietary power management and processing solutions.

Simon Hsu, Head of Automotive Business Unit at AUO, said, “ADI’s local dimming automotive display drivers provide power efficiency that meets AUO’s quality standards. AUO AmLED displays feature excellent power saving performance, outstanding readability in bright sunlight, and high contrast ratios, significantly enhancing driving safety and the in-vehicle entertainment experience. In line with smart mobility trends, AUO is continuously advancing display technology and looks forward to further collaboration with the ADI team.”

Patrick Morgan, Corporate Vice President overseeing Automotive Electrification and Sustainable Energy at Analog Devices, stated, “The future of the automotive experience is bringing consumer electronics capabilities into vehicles. In this collaboration, ADI’s technology and leadership in high-performance automotive power have enabled the launch of next-generation widescreen displays that support significantly improved power consumption and full functional safety characteristics.”

AUO uses the MAX25500 4 x 24 automotive LED matrix driver in its local dimming automotive displays. This product belongs to ADI's automotive local dimming display driver family and is currently being supplied in mass production.
