This technology enables local dimming, significantly improving power consumption by a minimum of 50% while also supporting functional safety requirements.
Vehicles are now incorporating widescreen displays throughout the cabin to deliver a more immersive experience. Increased automation and autonomy are also pushing the requirements of these displays from a typical infotainment hub to a safety centre with visuals surrounding the vehicle. In addition, the automotive industry is accelerating the transition to electric vehicles, where power consumption is increasingly important.
In response, ADI has developed an 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.
ADI said that it was looking to enhance the in-cabin experience by enabling energy-efficient widescreens capable of local dimming through proprietary power management and processing solutions, as well as high resolution displays through Gigabit Multimedia Serial Link (GMSL) serialiser and deserialiser (SerDes) connectivity solutions.
“The future of the automotive experience is to bring consumer features into the vehicle,” said Patrick Morgan, Corporate Vice President of Automotive Electrification and Sustainable Energy at Analog Devices. “Through this collaboration, we are bringing the next wave of widescreen displays into the market with significantly improved power consumption and full functional safety capabilities.”
