O2Micro Granted Patent

Date3-Jun-2003
SANTA CLARA, Calif. & GEORGE TOWN, Grand Cayman--(BUSINESS WIRE)--June 3, 2003--O2Micro® International Limited (Nasdaq:OIIM - News), a leading supplier of innovative power management and security ICs to mobile computer and communications manufacturers, was granted 29 claims under United States patent number 6,570,344 for its Inverter Lamp Grounding and Leakage Current Detection System.

The Lamp Grounding and Leakage Current Detection System provides a precise method for controlling CCFL current in multiple CCFL Common Ground Panel applications. The control method provides a tighter current tolerance amongst the lamps, resulting in a higher quality display with better uniformity of brightness and longer CCFL life. This patented methodology is ideal for LCD Monitor and TV, Notebook, DVD Player, and Game applications.

 

"This patent grant reduces backlight module assembly cost -- the cost per CCFL decreases as the number of CCFLs increase -- and simplifies CCFL wiring. This methodology is most advantageous when CCFLs are connected to LCD panel chassis," said Dr. Yung Lin executive vice president of O2Micro's Intelligent Lighting business unit.
