Highly integrated LCD video processor for next-gen ASIL B automotive display systems

Renesas Electronics Corporation has released the RAA278830 Video Diagnostics Bridge IC, a highly integrated dual LVDS LCD video processor. The new IC integrates many of the features essential to designing ISO 26262-compliant ASIL B automotive display systems, such as HUDs, digital instrument clusters, camera monitor systems (CMS), and electronic mirrors.

As automotive safety systems increasingly depend on display systems, it has become critical that clear, uncorrupted images be presented to the driver. Missing frames, frozen images, and even incorrect warning icons can seriously compromise driver safety. The IC meets these concerns with functional safety features built into the device specifically to avoid any image corruption through monitoring of signal integrity and video content. The internal diagnostics and measurement engines can detect frozen video, incorrect colours, broken or corrupt video images, and flashing, flickering, and video images that could obstruct the driver’s view of the road (in the case of HUD systems).

The company has a long and successful track record of providing video signal processing solutions for the automotive market. In addition to standard analog video decoders, it offers the award-winning Automotive HD-Link (AHL) family of products that enables high-resolution images to be transported over low-cost cables and connectors. The RAA278830 adds to the company's leading line of integrated LCD controllers that have been implemented worldwide.

“Our automotive customers have consistently asked us to add functional safety features to our industry-leading video processing technology,” said Jason Kim, vice president and general manager of the Configurable Mixed-Signal Division at Renesas. “The RAA278830 delivers all of the features needed to create safe, easy-to-implement and economical LCD display for all types of passenger vehicles.”
