Keywords:LCD TV  LCD panels  LCD modules  lawsuit 

Sharp Corporation filed a complaint with the US International Trade Commission (ITC) against Taiwanese company AU Optronics Corporation and certain customers of AUO that manufacture LCD TVs and LCD monitors. Sharp also filed a lawsuit against AUO at the U.S. District Court for Delaware. The company intends to file additional lawsuits in the event it confirms that other products incorporating AUO's LCD panels or LCD modules infringe its patents.

In the two complaints, Sharp alleges that LCD panels and LCD modules manufactured by AUO, as well as any LCD TVs and LCD monitors sold by AUO's customers in the U.S. that use these LCD panels and LCD modules, infringe upon seven U.S. patents owned by Sharp, all relating to LCD technology. At the ITC, it seeks an order prohibiting imports and sales of these products in the U.S. Additionally, at the District Court for Delaware, Sharp also seeks compensatory damages with AUO as the only defendant.

Particularly, the seven U.S. patents of interest in the lawsuit: US Patent No. 6,879,364 - relating to LCD apparatus controlling alignment; US Patent No. 6,937,300 - method of fabricating LCD devices; US Patent No. 7,057,689 - LCD phase compensation element to achieve a wide viewing angle; US Patent No. 7,283,192 relating to LCD devices having a wide viewing angle; US Patent No. 7,304,626 - circuitry that may reduce flickering and improved display characteristics; US Patent No. 7,532,183 - LCD device drive method; US Patent No. 7,838,881 - relating to active matrix substrate for use in display devices such as a LCDs.
