austriamicrosystems and LG.Philips LCD Develop High Precision LED Driver for Latest LCD Backlight Technology


(Wireless News Via Thomson Dialog NewsEdge)
austriamicrosystems, a designer and manufacturer of high performance
analog ICs for communications, industrial, medical and automotive
applications, announced that it has co-developed a new high precision
LED driver, AS3693, with LG.Philips LCD.

Designed for LCD TV backlight applications, the S3693 allows dimming of
multiple segments of the LCD TV backlight, enabling highest contrast
ratios and best picture quality. So-called block dimming results in
only the required segments of the backlight being on, making bright
spots in the TV picture really bright and dark parts completely black.

austriamicrosystems' AS3693 high precision LED driver offers control of
16 LED channels, where each channel can be controlled completely
independently via built-in PWM generators while withstanding up to 50V.
With the highest precision current control of 0.5 percent the AS3693
offers better accuracy than any competitor 16 channel LED driver
currently on the market, guaranteeing the most accurate control of the
LED light output for both white and RGB LED backlight panels.

A whole chain of AS3693 drivers can be controlled via SPI or I C making
the device the top choice for larger LCD panels. External clock and
synchronizing inputs allow the easy synchronization of the LCD
backlight with the TV picture. Built-in safety features include thermal
shutdown as well as open and short LED detection.

Markus Luidolt, Marketing Manager for LED backlight drivers at
austriamicrosystems, said, "To meet our customers' requirements,
austriamicrosystems developed this high performance solution tailored
to the specific needs of LCD TVs with LED backlight. Easy
synchronization with the TV picture and highest precision to achieve
optimal color and brightness levels are the most important
characteristics of our AS369x-product family which is seeing strong
interest from leading players in the LCD TV arena."

austriamicrosystems will present its new LED driver family for LCD TV
backlight applications in an off-exhibition suite at the Consumer
Electronics Show 2008 in Las Vegas.
