Dual-picture video processor powers automotive hi-res screens

April 12, 2016 // By Christoph Hammerschmidt
Toshiba Electronics Europe’s new dual picture video processor for high-resolution automotive displays provides support for navigation, entertainment and driver support systems that are increasingly found in cars.

With increased demand for larger panels with higher resolutions, Toshiba’s new video processor TC90195XBG supports 1920x720 at (60 frames per second (fps) and 1920x1080 at 30fps panels, improving on previous processors, which only supported up to WVGA resolution. The new device incorporates a built-in picture improver circuit to enhance low-resolution images for display on high-resolution panels. It can also output two digital video signals, to a WXGA+ panel and a WVGA panel simultaneously.


With its built-in frame memory and a line-drawing engine, the TC90195XBG can be used for rear-view camera systems as well as supporting rear-seat entertainment and infotainment systems.


The processor supports picture composition and picture separation modes with internal frame memory. The input stage complies with LVDS (OpenLDI) and LVTTL; a single image is composed from these two signals and displayed to a WXGA+ panel. Alternatively, it can separate the signals and output them independently to two panels, with resolutions of 1280 x 720 (LVDS output) and 800 x 480 (LVTTL output).

Samples oare available now; mass production is scheduled to start in June 2016.
