LCD controller can improve vehicle safety
Claiming to have the industry’s leading boot time, the TW8836 has both analogue and digital video inputs, a built-in scaler and de-interlacer, as well as image enhancement and On Screen Display capabilities. The single-chip LCD controller is designed to sync to a composite video source, scale and de-interlace the video, and display the image on the LCD panel in less than 500ms. The US National Highway Traffic Safety Administration will require rear-visibility technology to be standard equipment in all vehicles under 10,000 pounds from 2018. It will mandate that all new light vehicles sold in the US can display rear camera video within 2s from the time that the vehicle is put into reverse. No external memory is required and the video is latency free. As the main processors require time for the operating system to boot up, there is risk to routing the rear camera video through SoCs to avoid any glitches in the software compromising the reliability and integrity of the backup camera video. A special BT.656 output path is independent of the primary LCD scaler path, enabling system architecture flexibility. The chip can drive the panel directly and show rear camera video while the SoC is booting up. Once the SoC boots it can then route the source video to the SoC via the BT.656 path to support overlay of graphics on top of the video. The combined video can then be sent back to the controller for display on the LCD via the Open LDI (LVDS) or digital RGB input port. The LCD video processor can take virtually any type of video input—including analogue composite, S-video, analogue RGB, digital RGB and Open LDI (LVDS)—and drive almost any digital LCD panel up to WXGA (1366x768) resolution—including transistor-transistor logic (TTL), 1 CH Open LDI (LVDS) and timing controller-less (TCON-less) panels.
