Intersil's Market-Proven, Highly Integrated LCD Controller Technology Improves Vehicle Safety
June 02 2014 - 8:05AM
Intersil Corporation (Nasdaq:ISIL), a leading provider of
innovative power management and precision analog solutions, today
announced its latest generation LCD video processor—the TW8836—with
both analog and digital video inputs, a built-in scaler and
de-interlacer, as well as image enhancement and On Screen Display
capabilities in a single-chip, hardware-based solution. Intersil's
LCD controller family is the most mature and market-proven product
of its type. Designed for ultimate flexibility and quality, the
TW8836 can be used to display rear camera video with graphic
overlay in less than 500 milliseconds from the start of a vehicle,
exceeding government safety regulations. This versatile device can
be used in a wide array of infotainment system applications and is
optimized for use with today's most popular SoCs.

The National Highway Traffic Safety Administration announced in
March 2014 that "rear-visibility technology" must be implemented as
standard equipment in all vehicles under 10,000 pounds starting in
2018, as part of the Kids Transportation Safety Act. The move aims
to reduce the number of deaths and injuries caused every year by
backup accidents, most involving children or seniors. Specifically,
the new law mandates that all new light vehicles sold in the U.S.
have the ability to display rear camera video within two seconds
from the time that the vehicle is put in the reverse gear. Many
experts anticipate that other regions around the world will follow
suit by implementing similar laws.
The TW8836 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 500 milliseconds, far exceeding the fast boot
requirements outlined in the new U.S. law. Because the TW8836 does
not require any external memory, the video is latency free and thus
ultra responsive to help increase the backup safety of vehicles.
Since the TW8366 is a hardware-based solution, many automotive
manufacturers view the LCD video processor as more reliable in
terms of fast boot capability and as a more stable video path for
the rear camera than competing software-based solutions supported
by the main processor. Because the main processors require time for
the operating system (OS) to boot up, there is risk to routing the
rear camera video through SoCs as any glitch in the software could
compromise the reliability and integrity of the backup camera
video, resulting in a violation of the new U.S. safety
regulation.
The TW8836 provides a special BT.656 output path that is
independent of the primary LCD scaler path, enabling ultimate
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 up, it can then route the source video to the
SoC via the BT.656 path to support overlay of graphics (GUI) on top
of the video. The combined video can then be sent back to the
TW8836 for display on the LCD via the Open LDI (LVDS) or digital
RGB input port. Such features allow the TW8836 to be used in
conjunction with the most popular infotainment SoCs in the
market.
The TW8836 LCD video processor can take virtually any type of
video input—including analog composite, S-video, analog 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—making it an ideal solution for
rear camera display or multiple video source infotainment
applications. Due to the extreme flexibility and extensive input
and output video support, the TW8836 can be used by automotive OEMs
to support a wider variety of both analog and digital video
sources, as well as offload the video processing workload from the
main processor, allowing the processor to support additional system
functionality or the manufacturer may simply use a lower cost
processor.
The TW8836 helps optimize the system design and overall cost as
it supports differential composite inputs, eliminating the need for
an external op amp. In addition, the device does not need external
DRAM, helping to keep the bill of material (BOM) cost of
implementing the LCD video processor relatively low.
"Intersil is continuing to break new ground in the automotive
space by serving the market with an extremely flexible and reliable
LCD video processor solution that can be used to increase the
safety of vehicles as well as enhance an infotainment system's
ability to support a wide variety video sources at the highest
grade quality," said Philip Chesley, vice president of Precision
Products at Intersil. "Intersil has been the leader in automotive
LCD controller technology for over 10 years, which enables us to
best serve our long-standing OEM partners' design requirements and
deliver a safer, best-in-class experience for consumers."
