Toshiba launches video processor for high-resolution display panels

Published: April 12, 2016 | San Jose, California

Toshiba America Electronic Components, Inc. (TAEC), has rolled out a new dual-picture video processor for high-resolution automotive displays. In-vehicle driver support information displays are growing in use, prompting demand for larger panels with higher resolution. Toshiba’s new TC90195XBG video processor supports high-resolution widescreen (1920×720 pixels) panels, improving on the support for wide VGA (800×480) provided by the company’s existing product1. In addition, the TC90195XBG can also simultaneously output two digital video signals to two panels, instead of just one.

“According to IHS Automotive, the annual market for vehicle display systems is expected to reach nearly $19 billion by 20212,” said Deepak Mithani, senior director, Mixed Signal Business Unit, System LSI Group at TAEC. “These larger displays will require reliable video processor chips to ensure their ability to reliably display safety, infotainment, and other driver information with high picture quality. Toshiba designed the TC90195XBG to accommodate these needs, including its ability to output images to two in-vehicle displays – another key trend. We will continue expanding our automotive video processor line-up to meet growing demand.”

The new video processor features two-picture composition mode and picture-separation mode with internal frame memory. The input stage complies with LVDS3 (OpenLDI), LVTTL4 and analog video signal, and a single image is composed from these signals and transmitted to the primary display. The device can separate the signals and output them independently to two panels, with resolutions of 1280×720 (LVDS output) and 800×480 (LVTTL output).

The TC90195XBG’s built-in three-channel picture-improver circuit boosts low-resolution images for display on high-resolution panels. It features dynamic YC gamma, color management, and HVD enhancement. The processor includes a 10-bit AD converter, multi-color decoder to accommodate all major video formats (NTSC, PAL, SECAM), and power-supply voltage of 1.2V / 3.3V.
