Austria LG Philips LCD together with the development of microelectronics and LED drive

Global communications, industrial, medical and automotive applications IC design and manufacturer - Austria microelectronics analog (SWX:AMS) announced today (17), combined with LCD LG Philips LCD monitor supplier developing a new high precision LED driver AS3693 for LCD TV LED backlight applications, can achieve LCD TV backlight dimming with multi segment. The highest contrast and the best picture quality. The so-called block dimming refers to only the required period of the backlight light, TV screen is very bright and dark spot is black.

Austria microelectronics said, AS3693 high-precision LED driver can provide 16 LED channel control. When the voltage is up to 50V, each channel can be controlled independently by the built-in PWM generator. The highest current control accuracy of 0.5% AS3693, currently on the market than any one of the 16 channel LED driver has more excellent precision, can ensure the accurate control of white light and RGB LED backlight panel LED optical signal output.

Austria microelectronics, said the 2008 consumer electronics show will be held in Las Vegas, Garth, the display of the LCD TV backlight applications designed for the new LED driver series.
