Optimized for integrated multi-display cockpit systems, the fourth-generation SC172x Series of smart display controllers for automotive applications allow the implementation of even larger multi-display applications, also delivering the enhanced image quality needed for larger display sizes and higher resolution.
The SC172x Series is equipped with an APIX®3 SerDes-repeater function that allows daisy-chaining of multiple smart display controllers, enabling up to four display connections in a chain. By simplifying the integration of multiple displays, this function represents a significant improvement in vehicle wiring efficiency compared to the third-generation controllers.
Along with support for image compensation, the smart display controller meets the need for enhanced image quality, with LED control and pixel compensation by Local Dimming, and Warping-on-the-fly dynamic interpolation of the Warp Map.
As well as strengthening existing safety functions, with system safety being enhanced by adding a mechanism to monitor external LED driver error detection and internal algorithm, these smart display controllers support functional safety (ASIL-B) by complying with the ISO26262 development process.
